A New York Times article dated Nov. 22, 1936, quotes from a lecture titled “Discoveries and Inventions” Lincoln gave in 1860, before he became president. Here’s the relevant part:
“Of all the forces of nature, I should think the wind contains the largest amount of motive power … Take any given space of the earth’s surface, for instance, Illinois, and all the power exerted by all the men, beasts, running water and steam over and upon it shall not equal the 100th part of what is exerted by the blowing of the wind over and upon the same place.
And yet it has not, so far in the world’s history, become properly valued as motive power. It is applied extensively and advantageously to sail vessels in navigation. Add to this a few windmills and pumps and you have about all. As yet the wind is an untamed, unharnessed force, and quite possibly one of the greatest discoveries hereafter to be made will be the taming and harnessing of it.”
Securing the World’s Largest Wind Turbine
Jim Bell, Managing Director, FoundOcean
At 7 megawatts (MW), Samsung Heavy Industries' S7.0-171 is the world's largest offshore wind turbine. The 196-metre tall structure is being installed 20 metres offshore in Fife, Scotland, with a connecting walkway to enable visitors to get up close to the structure.
GE Wants To "Power Up" Older Wind Turbines
Bringing the "brilliant" abilities of GE's newer wind turbines to its existing fleet means more output and profitability per turbine. Here's how.
Vestas wins 108 MW order for one of the largest wind power plants in Romania (http://www.pic4ever.com/images/8.gif)
36 V112-3.0 MW turbines ordered for the Crucea North wind project
With reference to Vestas Wind Systems A/S company announcement No. 44 of 10 October 2013, Vestas is pleased to announce a firm and unconditional order for 108 MW from S.C. Crucea Wind Farm S.R.L. / STEAG GmbH for the wind power plant Crucea North, located in the Constanta county in the province of Dobrogea.
The order includes supply, installation and commissioning of the turbines, along with a VestasOnline® Business SCADA solution as well as a 10-year full-scope service agreement (AOM 4000). Delivery is planned to start in April 2014 and commissioning is expected to be completed by December 2014.
The Crucea North wind power plant is one of the largest in Romania and represents a step forward in the development of Vestas’ relationship with one of the key players in wind energy in Europe.
”The negotiations with Vestas for one of STEAG’s biggest projects in wind energy have been efficient and focused,” states Dr. Ralf Gilgen, member of the Board of Management of STEAG GmbH. “We expect this to be the starting point for a successful strategic partnership in the development and realisation of international wind energy projects.”
“We are pleased to receive the Crucea North order from our valued customer Crucea Wind Farm S.R.L. / STEAG GmbH. This wind energy project marks another important milestone in further developing the Romanian wind market, and we are happy to support our customer’s business case with our 30 years of wind energy experience and efficient wind energy solutions,” says Thomas Richterich, President of Vestas Central Europe. “With this order Vestas reinforces its market leading position in the Romanian market having the strongest local presence and the largest operational fleet.”
The wind project totalling 108 MW will be a key contributor to Romania’s ambitious targets as detailed in its National Renewable Energy Action Plan. The 36 V112.3.0 MW wind turbines will produce more than 300 GWh per year, which corresponds to an annual saving of almost 124,000 tons of CO2 emissions. Furthermore, it will provide enough electricity to cover the residential electricity consumption of more than 550,000 persons in Romania.
As of 30 June 2013, Vestas has delivered 654 V112-3.0 MW turbines worldwide representing a total capacity of more than 1.9 GW, and has received more than 4.5 GW of firm orders for this model.
Every single day, Vestas wind turbines deliver clean energy that supports the global fight against climate change. Wind power from Vestas’ almost 50,000 wind turbines currently reduces carbon emissions by over 60 million tons of CO2 every year, while at the same time building energy security and independence. Today, Vestas has installed turbines in 73 countries, providing jobs for around 17,000 passionate people at our service and project sites, research facilities, factories and offices all over the world. With 62 per cent more megawatts installed than our closest competitor and more than 57 GW of cumulative installed capacity worldwide, Vestas is the world leader in wind energy.
The headquarters of Vestas Central Europe is located in Hamburg, Germany. The business unit is responsible for the sales and marketing of wind power systems as well as for the installation and operation of wind power plants in Germany, Benelux, Austria, Russia, Eastern Europe and Southern and Eastern Africa.
Vestas entered the Romanian market in 2008 and is now the market leader here, with headquarters in Bucharest as well as several working sites in the field for construction and service activities. The local economy benefits greatly from wind energy’s ability to drive economic growth; skilled jobs are created also in remote areas and around 60 per cent of the revenues generated through the lifetime of a modern 3 MW wind power plant go to local construction companies, suppliers, service providers and communities.

I looked up the average wind speed at Chicago (I'm certain it is much higher a hundred stories up in any of their many skyscrapers that could easily be fitted with wind turbines).
It turns out that, over a century ago, Chicago earned that nickname, not because of high wind speeds, but because:
Chicago has been called the “windy” city, the term being used metaphorically to make out that Chicagoans were braggarts. ;D
While Chicago is widely known as the "Windy City", it is not the windiest city in the United States: Milton, Massachusetts is. Chicago is not significantly windier than any other U.S. city. For example, the average annual wind speed of
Chicago is: 10.3 mph (16.6 km/h);
Milton is: 15.4 mph (24.8 km/h);
Boston: 12.4 mph (20.0 km/h);
New York City, Central Park: 9.3 mph (15.0 km/h); and
Los Angeles: 7.5 mph (12.1 km/h).
Many cities have higher average wind speeds BUT Chicago has skyscrapers. I have always wondered why they haven't started putting wind turbines on top of them. Yes, a structural engineering firm would have to do some beefing up of the building to handle the extra stresses and load but it would be worth it. If the average wind speeds are 20 mph or better a skyscraper height, you have a 24/7 continuous city power source built in to a metropolitan area (a high energy use area).

Spain’s First Offshore Wind Turbine Inaugurated
The first offshore wind turbine for wind energy company Gamesa and for the host-country Spain was inaugurated on Monday, in in Arinaga Quay (Gran Canary Island). The ceremony was attended by the President of the Canary Islands regional government, Paulino Rivero, the Minister for Industry, Energy and Tourism, José Manuel Soria, and the Chairman of Gamesa, Ignacio Martín.
The 5 MW 154 meter-tall turbine has a rotor diameter of 128 meters, sporting 62.5 meter-long blades, all combining to produce enough energy to supply 7,500 Canary Island homes with clean energy.
Gamesa is noticeably excited about their entrance into the offshore wind market, proclaiming that “Gamesa’s platform is set to become a benchmark in the sector thanks to the low cost of energy it offers customers.”
They were equally proud of the fact that the turbine parts were all made in Spain, noting however that “teams from all over the world participated in the product’s design and development phases”, including:
•The blades, each of which measures 62.5m long and weighs 15 tonnes, making them the longest ever produced and transported in Spain and among the longest in Europe, were made at the factory in Aoiz (Navarre)
•The nacelle, which measures over 12.5m long, 4m tall and 4m wide and weighs 72 tonnes, was made in Tauste (Zaragoza)
•The tower, which stretches nearly 90m high, was made by Windar (a joint venture between Gamesa and Daniel Alonso)
•The electric parts were made in Lerma (power train), Benissano (electric control cabinets), Coslada (converters) and Reinosa (generator)
Spain is one of the world’s largest wind energy producers in the world, and leveraging their extended coastline to further their dominant role in the industry will see enormous benefits for country and industry alike. (http://www.freesmileys.org/emoticons/tuzki-bunnys/tuzki-bunny-emoticon-022.gif)
Siemens*, or at least the company it has commissioned to make the video above, knows how to make a wind power advertisement.
One of the key takeaway impressions people seem to have after visiting a wind turbine up close (or even going to the top of one) is how entirely awesome and majestic these giant machines are. They’re staggering in their height and power.
And I’m sure offshore wind turbines are even more impressive, especially the 6-megawatt ones and 7-megawatt ones.
In this new Siemens video, all of this is excellently portrayed in cinematic style — not your typical “green” or cleantech advertisement.
Since Siemens is the company behind this excellent contribution to cleantech messaging and wind turbine branding, I thought I’d share more about what it has been up to in this space. Here are a few of the company’s recent wind power highlights:

4.Siemens To Provide 80 Wind Turbines For Giant German Offshore Wind Power Plant
5.Siemens CEO: Cleantech Is A “Vital Part Of Our Business” (VIDEO)
6.World’s Largest Wind Turbine Rotor Goes Online
Together with other wind power leaders, it should be noted that the cost of wind power has come down tremendously in recent years, from over 30¢/kWh 10 years ago to as low as 4¢/kWh today. :o Notably, this cost dropped has largely been brought on by making wind turbines larger and larger, more and more majestic.
wind turbines getting bigger and bigger
While the cost optimization from making onshore wind turbines larger and larger seems to be hitting a limit, larger offshore wind turbines may provide useful benefits for the quite different offshore wind environment. Hence the 6- and 7-MW wind turbines. Simply look above at how a 7-MW wind turbine compares to an Airbus A380 with a wingspan of 80 meters to get an idea of how humungous these machines are.
*Full Disclosure: This post was supported by Siemens through Be On media. That said, I wouldn’t have covered it if I didn’t think it was worth covering, and nobody from Siemens or Be On had any influence over what I wrote above.

The 120 MW Ashegoda wind farm in Ethiopia, now the largest wind farm in the whole of Africa, officially went online last weekend. As it stands, Ashegoda has actually already transferred around 90 million kWh of electricity to the grid. Now that its fully online it’s expected to produce around 400 million kWh a year. (http://www.clker.com/cliparts/c/8/f/8/11949865511933397169thumbs_up_nathan_eady_01.svg.hi.png)
The project, which was announced in 2008, was constructed over the last few years in a series of stages. When the first stage went online, it was the first of its kind in Ethiopia.
Image credit: EEPCo
Ashegoda is located about 18 kilometers outside of the city of Mekelle in Ethiopia. The Adama I and Adama II wind farms were also recently completed, boasting 51 MW of capacity each. They are located just south of the Ethiopian capital of Addis Ababa. The Ashegoda project was funded by the French bank BNP Paribas, the French Development Agency (ADF), and the Ethiopian Electric Power Corporation (EEPCo) — EEPCo will also manage the site.
Business Green provides some background on renewable energy development in Ethiopia:
Ethiopia has one of the fastest growing economies in the world, averaging growth of between 8% and 10% for each of the last 10 years. Last year UK Energy and Climate Change Minister Greg Barker led a clean tech trade delegation to the country as part of a wider mission to East Africa to help UK firms tap into what he called a ‘huge’ opportunity for green energy.
Ethiopia has an estimated 45 GW of hydroelectricity capacity potential, 10 GW of potential wind capacity, and 5 GW of geothermal potential. While the government’s current five year development plan envisages increasing the country’s current power generation capacity to 10 GW by 2015, to date it has only tapped around 2 GW of its green energy capacity.
With regard to the wider development environment in Africa, renewable energy development there has been largely centered around off-grid solar, but larger projects have been becoming somewhat more common in recent years. For example, see:

UK Offshore Wind Capacity Rises 80 Percent in One Year
Kelvin Ross, Deputy Editor, Power Engineering International
November 08, 2013
LONDON -- The installed capacity of the UK’s offshore wind sector has risen by 79 percent in a year. In the period from July 2012 to June 2013, capacity increased from 1,858 MW to 3,321 MW, boosted by four huge wind farms becoming operational – Greater Gabbard, Gunfleet Sands III, Sheringham Shoal, and London Array, which at 630 MW is currently the biggest offshore wind farm in the world (http://www.clker.com/cliparts/c/8/f/8/11949865511933397169thumbs_up_nathan_eady_01.svg.hi.png)
The increase is revealed in a new report, Wind Energy in the UK, compiled by trade group RenewableUK, and it marks the first time in a 12-month period that installed offshore capacity has outstripped onshore, which stood at 1258 MW.
Nevertheless, onshore also saw an increase of new capacity by 25 per cent, bringing its total capacity to 6,389 MW.
Onshore and offshore, a total of 2,721 MW were installed between July 2012 and June 2013, taking the UK’s total wind capacity up from 6,856 to 9,710 MW — a 40 percent increase. ;D
RenewableUK says that onshore, project sizes are declining overall, “due partly to the growth of the vibrant sub-5-MW market under the feed-in tariff, with projects at this scale now making up two-thirds of new onshore submissions. Other factors include a reduction in the availability of larger sites, and developers’ responses to changes in the planning system.”
However, the report notes that there are concerns within the wind industry about levels of political support and the government’s ambition for the sector, leading to a decline in confidence.
But it points out that despite this, “there is a substantial pipeline of projects under construction, approved but not yet built, and in planning”.
RenewableUK’s chief executive Maria McCaffery said: “We’ve smashed another record in the past year with more offshore wind installed than ever before — the 79 percent increase in capacity within 12 months is a terrific achievement. With onshore expanding by 25 percent, the wind industry as a whole has proved that it has the tenacity to achieve substantial growth.”

Yes. UK is leader of Offshore wind energy in the world. Though India is 5th in the world in Wind not even a KW Offshore wind turbine is erected! It is indeed a pity. In almost every field, we follow west. The time has come we should be INNOVATORS rather than remain as IMITATORS.I have been advocating Offshore Wind Farms for over a decade in India.
Also Wind Farm Co-operatives on the lines of those in Denmark, Germany etc. in India. A Wind Fund can be created and contributions to it can be exempted by Government of India under Section 80C. This way there will be mass participation in Wind Sector. Hitherto incentives are provided to big wind farm owners like Depreciation. When Private participation in the Renewables is given a big push, India can be a leading country in the Renewables especially WIND.
What is needed are sound policies and political will to push this clean energy. (http://www.pic4ever.com/images/301.gif) A Good R &D Effort in the Private Industry will help to improve the quality of the Wind Turbines and also accurate micro siting. (http://www.pic4ever.com/images/128fs318181.gif)
In this connection DEWI Micrositing Experience and Research activities have helped to get maximum output at Wind Farms in Germany and elsewhere.
Reliable predictions of the energy yield of wind farms are only possible on the basis of accurate near-site wind speed measurements. The critical aspects are selection of where the tower is to be placed, selection and calibration of anemometers, the height of the met mast and the installation of the sensors on the met mast. DEWI has been specialised in this area for many years and also offers additional services such as site calibration or long-term wind measurements for wind farm monitoring.
Apart from the general economic conditions of a planned project, an accurate measurement of the wind speed is the decisive factor in determining the economic efficiency of a wind farm. An error of 3% in the wind speed measurement can lead to a discrepancy of about 10% in annual energy production. It is therefore absolutely necessary to calibrate an anemometer individually before a measurement campaign; this is offered by DEWI as an accredited service.
DEWI’s Micrositing Department, with its longstanding experience in services and research activities, offers investors, developers and owners a high-quality, reliable data basis for planning wind farm projects worldwide. DEWI offers the whole range of services, from site inspection and analysis of existing wind measurement data to calculation of energy yield and wind farm efficiency and creation and optimisation of the wind farm configuration taking into account all important parameters specific to the site. On request, DEWI experts can also assist in the installation of meteorological measuring equipment and the analysis and checking of existing measurements.
For the simulation of wind and turbulence conditions in complex terrain, DEWI Micrositing offers special 3D CFD (Computational Fluid Dynamics) calculations, which are becoming increasingly important in international projects. This complex, cutting-edge calculation method allows investors, developers and owners to obtain the best possible prediction of the real turbulence conditions at the site.Similar methods can be adopted in India as well and Private Wind Industry should take lead in adopting best technology.

Snowtown II: Wind Power At A Cut-Throat Price! (http://carrieamedford.com/wp-content/uploads/money-emoticon.gif.jpg)
Windenergieanlagen für das Projekt "Snowtown II" / Wind turbines for Snowtown II wind farmSnowtown is a small rural community which is famous throughout Australia on account of how it once snowed there. Or possibly the place was simply named after a man called Thomas Snow. Either one. Land nearby is already the location of the imaginatively named wind farm Snowtown I, and is now the construction site for a brand new wind farm for which they’ve really gone out on a creative limb for and named Snowtown II. When completed towards the end of 2014 it will be Australia’s second largest wind farm and South Australia’s largest. One very exciting thing about this wind farm sequel is it looks set to provide some of the cheapest grid electricity in Australia. But more on that later. Now it’s time for me to give some bodacious details about this development.
Ninety Siemens wind turbines of three megawatts capacity will be erected on 80 meter high steel pylons for a total of 270 megawatts. The blades on 80 turbines will be 53 meters long while the remaining 10 will have 49 meter blades. Local farmers will receive $2.4 million a year for the use of their land and the expected lifespan of the wind farm is 25 years. Enough electricity will be produced to meet the demand of 90,000 Australians or 173,000 Italians. The total cost will be $439 million Australian which is $413 million US at current exchange rates.
The turbines are a gearless direct drive design. Not having a gearbox cuts the number of moving parts almost in half and saves money by reducing maintenance requirements by about 20% while having the disadvantage of increased weight. An interesting thing about this design is it rotates the generator around a shaft which is the opposite of how it’s usually done. Another interesting thing is that 10 of the turbines will have blades 4 meters shorter than the others meaning they will catch about 14% less wind. While this may seem a waste as it will make them less efficient in slow to moderate winds, they will be able to keep operating at very high wind speeds that can force longer bladed turbines to shut down and so makes the output of the wind farm more constant.
One thing I should probably tell you about Snowtown is the place really blows. (http://www.4smileys.com/smileys/seasons-smileys/storm.gif)
It blows so much that the existing wind farm has an excellent capacity factor of about 42%. (http://www.pic4ever.com/images/19.gif) This is one of the reasons why the new development will provide electricity at very low cost. Just what the exact cost will be depends on a variety of factors, but since air is currently free this means wind power has no fuel cost and so the capital cost of borrowing money is the largest component.
Using a 5% discount rate and a 25 year lifespan gives a capital cost of 3.1 cents per kilowatt-hour produced. ;D This may actually be a little high as the current parlous state of the world economy means it might be possible to borrow money for less than 5%, but it would be almost correct for Australia and as these sorts of calculations often use a 5% figure there are benefits in being consistent. Note that in places such as Europe, Japan, China, and the USA it is possible to borrow money at a considerably lower rate which significantly decreases the capital cost of wind power for them.
In addition to the capital cost there are payments to farmers for using their land. While less than 1% of the land will be removed from use by the wind turbines and they will improve the land by reducing wind speeds, the payments do add up and increase the cost of electricity to 3.4 cents per kilowatt-hour produced. Then there’s the cost of maintenance, integrating wind power into the grid, and other miscellaneous costs. Just exactly what they will add up to for the latest direct drive wind turbines I’m not sure, but a very rough rule of thumb for modern wind farms is 2% of the total capital cost per year which gives a total amount of 4.3 cents per kilowatt-hour.
But are my estimates correct? To check that I’m not merely tilting at windmills of the mind, I looked up the costs of running a wind farm given by the United States’ National Renewable Energy Laboratory. Adding the latest figures from 2012 for the fixed and variable costs for wind power to the capital cost give a result very close to my own of around 4.4 cents a kilowatt-hour or about 4.1 American pennies. Given that the average cost of Australia’s mostly fossil fuel generated electricity is about 5.6 cents a kilowatt-hour that’s quite a bargain. And the cost may actually be lower because, generally speaking, the more modern a wind farm is the lower the maintenance costs.
Some people mistakenly believe that electricity from wind farms isn’t as useful as that from coal power because wind is variable in its output, but when it comes to selling electricity to customers, wind and coal power are basically equal. In Australia our electricity market is divided into two parts.
The main part is selling electricity to consumers and over the time scale that electricity is sold we can very accurately predict the output of wind farms making wind and coal power almost the same for this purpose. (http://www.freesmileys.org/emoticons/tuzki-bunnys/tuzki-bunny-emoticon-005.gif) The other much smaller part of the electricity market involves stabilizing the grid and making sure it can deal with sudden increases in demand or falls in the supply of electricity.
In Australia we call this ancillary services. And when it comes to ancillary services wind power truly sucks. It sucks because the wind does not blow on command. But the solution to this is simple. Don’t use wind power for ancillary services. It’s a really stupid thing to do. While it’s not hard to find people on the internet complaining that wind is not suited for providing grid stabilization, it makes about as much sense as complaining that steel wool is not good for polishing your car. It’s not supposed to be! (http://www.freesmileys.org/emoticons/tuzki-bunnys/tuzki-bunny-emoticon-005.gif)
The low cost of electricity from Snowtown II combined with other developments such as the decreasing cost of solar power means that Australia will never build another coal power plant. This is something I’m very excited about. (http://www.clker.com/cliparts/c/6/7/1/12065737551968208283energie_positive_Wind_Turbine_Green.svg.hi.png)Renewable energy schemes like Snowtown II will leave coal for dead in Australia and that’s something you can take all the way to the bank. (http://www.pic4ever.com/images/128fs318181.gif)
Local residents are also very excited about the wind farm and in fact it is the most interesting thing that has ever happened to Snowtown. (http://www.freesmileys.org/emoticons/emoticon-animal-067.gif) If you don’t believe me, ring up the town and ask them. I dare you. (http://www.imgion.com/images/01/Angry-animated-smiley.jpg)

Efforts to Protect Raptors from Colliding With Wind Turbines Make Progress
Wind developers have long struggled with how to prevent birds - especially eagles and hawks - from crashing into turbines, and a solution may be at hand thanks to efforts at Montana's largest wind farm.
126 wind turbines comprise the 189 megawatt Rim Rock Wind Facility that's spread across 21,000 acres. By today's standards, the turbines are small at 1.5 megawatts each.
When NaturEner USA developed the project, which at peak production supplies 60,000 homes, it worked with the local Audubon group to site turbines as far as possible from raptor nesting sites.
Wind Farm RimRock Montana
But it's been a combination of human observers and radar tracking cameras that "provides the best kind of protections that have been deployed anywhere in the US," Greg Copeland, vice president of wind energy development told Associated Press.
Protecting raptors is being put to the test because the wind farm is near sandstone cliffs - prime habitat, where eagles and hawks nest in rocky outcroppings.
Since Rim Rock started operating late last year, only two raptors have died - a tiny number compared to typical wind farms.
How They Do It
Human observers - trained avian biologists - scan the skies from three locations throughout the day using high resolution spotting scopes.
Combined with radar tracking cameras, they can detect raptor flight patterns as far as 1200 miles away. When a likely collision is identified, they alert the San Francisco operations center to shut down turbines, which can be done in as little as 30 seconds.
That isn't a problem for power output because the wind farm is divided into zones, each with 4-8 turbines. When a shut down order is given, it applies to a particular zone, allowing the majority to keep operating. And shut down times range from 3- 30 minutes.
Rim Rock has had much more success using radar because it places the detection system outside the wind farm instead of in the interior, as most other developers do (which causes interference).
If raptors somehow get past the radar and human "biomonitors," there's a last line of defense - cameras mounted on turbines. The cameras have software that visually tracks raptors and if a bird flies within 200 meters of a turbine, it triggers a high frequency noise and flash of light that drives them away.
Finally, during times of year when wind patterns tend to push birds toward certain turbines, the company proactively shuts them down ahead of time and keeps them that way until the wind shifts.
Copeland calls this a "layered approach" and credits it as the key to successfully avoiding bird collisions. Through all this monitoring they have found that raptors are on the wind farm's footprint only about 10% of the time.
Copeland estimates the cost for buying and maintaining the radar units at about $750,000 over 5-10 years. That may seem like a lot of money, but it's worth it, he says, because they are a green company that cares about wildlife. And it also keeps potential regulation at bay.
Wind turbines generally kill fewer birds these days than older versions of the technology because blades are much larger and move more slowly. Still, at their tips they can turn at 200 miles per hour. Raptors are looking down for food, they don't expect a huge airborne object to strike them, Steve Hoffman, Executive Director of Montana Audubon told Great Falls Tribune.
More Difficult for Bats
Because bats are so small and fly at night, it's much harder to protect them from collisions - which happen at just about all wind farms.
In addition to colliding with turbine blades, they can be traumatized by changes in air pressure created as they turn.
Well over 600,000 bats are killed by turbines every year, according to research by Mark Hayes at University of Colorado, Denver. Other researchers believe it's as high as 880,000 deaths. Bat deaths are highest in the Appalachian region, says Hayes.
He believes a solution will be found for bats. Research is underway on sounds that may deter bats from turbines; another solution could be closing down turbines during times when bats are found to be most active.
Both raptors and bats are of particular concern because of their low fertility rates, giving birth to just one offspring a year. And bats are being further decimated by white nose syndrome.
The Bats and Wind Energy Cooperative has been working on ways to help bats for years. The alliance consists of Bat Conservation International, the American Wind Energy Association (AWEA), the U.S. Fish and Wildlife Service and National Renewable Energy Lab.
Studies are also underway to track the flight patterns of marine birds that could collide with offshore wind turbines.
Alstom Completes World’s Largest Offshore Wind Turbine
French engineering company Alstom have announced the completion of their at-sea installation of its new-generation offshore wind turbine, the 6-MW Haliade 150, located off Ostend Harbour at the Belwind site in Belgium.
The turbine, the largest offshore wind turbine ever installed in sea waters, boasts a 78 metre tower, a nacelle that stands 100 metres above the waves, blades over 73 metres in length, and pillars sunk over 60 metres into the seabed to support the mammoth construction.
As a result of its impressive specifications, the Haliade sports a yield 15% better than existing offshore turbines, allowing it to power approximately 5,000 households on its own.
“This project with Belwind asserts our technological leadership and our innovative abilities,” said Alstom Wind Senior Vice-President Alfonso Faubel. ”The installation of our turbine which is simple, robust and efficient thus contributing in boosting the competitiveness of offshore wind energy.”
The Haliade operates without a gearbox, (http://www.clker.com/cliparts/c/8/f/8/11949865511933397169thumbs_up_nathan_eady_01.svg.hi.png) instead working with direct drive, and due to a permanent-magnet generator there are fewer mechanical parts inside the device, which not only makes it more reliable but also helps to minimise operating and maintenance costs faced by traditional offshore wind turbines.
Given the specific expertise necessary to not only maintain a wind turbine, but one located offshore in likely-stormy waters, reducing operating and maintenance costs is a necessity many companies are striving towards. (http://www.pic4ever.com/images/earthhug.gif)
“Belwind’s tried and tested expertise in completing offshore projects and setting up wind farms has helped Alstom to perform the installation work in sea waters under the best possible conditions,” said Belwind chairman Wim Biesemans. “We are convinced that Alstom’s innovative wind energy technology will contribute in providing one of the future solutions to ensure clean, reliable and efficient energy.”
Five thousand households from just ONE wind turbine.
The fossil nukers out there will, once again, be forced to lower their ridiculous hyperbole about "how many" of this, that or the other Renewable Energy devices from PV to wind turbine numbers it would take to replace fossil fuel centralized dirty energy.
Latin America Report: Wind Sweeps Brazil's A-3 Power Auctions
Brazil Wind energy resources Map
Renewable Energy World Editors
November 21, 2013
New Hampshire, USA -- Brazil's latest A-3 auction, matching up developers and power purchasers to prepare renewable energy projects to meet the nation's electricity demand by 2016, was a landslide win for wind energy -- but a shutout for solar, which was included in the process for the first time.
More than 58 million MWh were sold for a total of U.S. $7.2 billion, according to the National Electric Energy Agency (ANEEL). An extra feature of the A-3 auction: developers are responsible for hooking their projects to the grid. The pool of qualified participants had included 429 projects exceeding 10.4 GW, the vast majority of which were wind (381 projects totaling over 9.1 GW) but also some solar PV (31 projects, 813 MW capacity) and some small hydro and biomass.
The overwhelming winners were wind energy developers, who saw 39 wind projects approved totaling 867 MW of capacity, nearly half of them in the southern state of Rio Grande do Sul. Two-thirds of those purchases were backed by Electrobras subsidiaries Electrosul and Furnas. By the end of this year, Brazil could end up auctioning a record 3 GW of wind.
On the downside, no bids were offered for any solar PV projects, :( which had been included for the first time. The low pricing (average 124.43 Brazilian reais/MWh, just under the ceiling price of R 126/MWh) had been roundly expected to be too low for solar projects which currently cost more than R 200/MWh. Two solar-friendlier alternatives reportedly are being explored: reducing the price of power on the market, or conduct solar-only auctions with a more applicable pricing structure.
IN THE NEWS
Chilean Solar Plant Updates: SunEdison has closed $100.4 million in debt financing for its proposed 50.7 MWp; San Andres solar plant in Chile, said to become the largest merchant solar plant in Latin America when it comes online in early 2014.

Solar Partnership in Puerto Rico: Schneider Electric and Fonroche have agreed to develop a 40-MW solar field in Humacao, promised to be the Commonwealth's largest plant upon completion.
70-MW Solar PV Plant Coming to Argentina: Schmid and M+W, with state energy supplier Energia Provincial Sociedad del Estrado (EPSE), have committed to design and build a 70-MW solar PV production facility in San Juan to produce monocrystalline silicon ingots through glass/foil modules starting in mid-2015, targeting use in the region's gold and copper mines and irrigation systems. A second phase will expand into upstream polysilicon manufacturing.
A DEEPER LOOK
The Untapped Potential of South American Geothermal: South America holds great potential for geothermal energy, but barriers to development have kept it largely unrealized. However some private investors and development banks are on the cusp of unlocking the abundant energy source. Our own Meg Cichon takes a closer look at this "open frontier" for geothermal energy development here on this lower end of the Ring of Fire horseshoe.
Tracking Latin America's Clean Energy Investment Climate: Latin America and the Caribbean captured six percent of the total $268 billion invested worldwide in clean energy in 2012, slightly more than the year before, thanks to strengthened government policy support and expanding supply chains, according to Climatescope 2013, a report from the Multilateral Investment Fund (MIF) and Bloomberg New Energy Finance (BNEF). Their interactive deep-dive and infographics illustrate where each nation stands in four key areas: enabling framework, clean energy investment and climate financing, low-carbon business and clean energy value chains, and greenhouse gas management activities. Among the study's encouraging data points: retail power prices remain generally high across the region which makes deployment of renewables more attractive, and nearly all of identified "value chain" links are filled. There are 927 carbon offset projects across the region, more than half of which are for power generation. And eight countries now have net metering laws.
ON THE HORIZON
Latin American Wind Capacity Doubling in a Decade: Latin America is the hottest growth market for wind energy, and installed capacity will roughly double by 2022 to 4.3 GW, according to a report from Navigant Consulting. Policy and macroeconomic challenges are slowing wind energy adoption in other regions, but Latin America will account for nearly 6 percent of global new wind power installations this year alone, and will "exhibit double-digit compound annual growth rates through the next 10 years," according to research director Feng Zhao. Brazil's latest wind power auctions led to 1.5 GW of new wind capacity and helped stabilize higher prices, he noted, and will provide the foundation for wind energy growth in the entire region.
Pricing Hydro Bids for Brazil's A-5 Auction: The second A-5 auction to be held Dec. 13 has been approved, contracting for renewable energy projects coming online in mid-2018. They include several hydropower projects bigger than 50 MW and priced at around $107-$139/MWh, with smaller ones priced at R 144/MWh.

Vestas Supplies Refurbished Wind Turbines to Developing World
To help the developing world stop relying on dirty diesel generators and switch to clean energy, wind turbine manufacturer Vestas and Masdar's renewable energy arm are bringing hybrid wind to rural communities that are off the grid.
Their collaboration, "Wind for Prosperity", plans to bring wind energy to one million people in 100 communities in the next three years. (http://www.freesmileys.org/emoticons/emoticon-object-081.gif)
"This is one of the biggest corporate initiatives to combat energy poverty and deploy green technology in developing countries. It's a triple win - generating growth, reducing pollution, and doing both profitably," says Morten Albæk, Group Senior Vice President for Vestas.
Communities will receive factory-refurbished wind turbines that are easy to transport, erect and maintain, combined with advanced diesel for backup.
Using Vestas's weather data processing capabilities, the partners are identifying parts of the world that desperately need energy and where there's lots of wind.
Masdar will serve as project developer and Vestas will focus on project design and sourcing and refurbishing wind turbines.
About 13 communities in Kenya - where about 200,000 people live - will be the first project sites starting in mid-2014, in partnership with investment group Frontier Investment Management. Other countries that are on their short list: Ethiopia, Tanzania, Yemen, Pakistan, Vietnam, and Nicaragua.
"We expect this to be a successful investment commercially -adding to the bottom line in the near term and helping to open new markets to wind energy further down the line," says Albæk.
"There was a time when corporate executives like me would throw money at solving these problems, ignoring our business savvy, our models, our metrics, in the spirit of aid. But we arguably did more harm than good -- and we certainly haven't solved the problem of poverty. So I believe it's time for a new vision.
It's time for partnerships that promote collaboration, not dependency. (http://www.pic4ever.com/images/47b20s0.gif) It's time for investment, not charity. It's time to deploy the world-class knowledge and technology we have, putting it to use for profit -- in multiple senses of that word. It's time for an initiative like Wind for Prosperity," says Albæk.
"We can help bring the many benefits of electrification -- improved health care, brighter educational prospects, easier access to water, better tools for agriculture, some new jobs, a big boost to business. We can lower the cost of electricity generation by at least 30 percent. We can take fuel trucks off the road and provide an alternative to the dirty diesel that, if even available, is often the only power-generating option. And we can make money doing it. It's a win-win-win-win scenario. Who could or would say no?" ;D
U.K. Wind Turbines Generate Record Power as Gas Plants Halt
Rachel Morison, Bloomberg
December 02, 2013
LONDON -- Wind power in the U.K. rose to a record, leading operators from RWE AG to SSE Plc to halt more expensive gas-fired power generation plants.
Wind output rose to as much as 6,053 megawatts at 2:10 p.m. London time today, beating a previous record on Sept. 15 and accounting for 14 percent of total supply, according to National Grid Plc data on Bloomberg. Generators halted 7,872 megawatts of gas-fired plants since yesterday, grid data show.
The U.K. plans to almost triple the amount of wind capacity by 2020 as it seeks to meet a target to get 15 percent of power demand from renewable energy sources. Wind and solar have no fuel costs, generally making them cheaper than coal or gas.
“As well as the higher wind power, demand is down by about 2 gigawatts from yesterday as well so it has given the chance for less efficient gas-burn facilities to drop output,” Gary Hornby, energy markets analyst at Inenco Group Ltd., said by e- mail today.
Wind may generate an average of 5,301 megawatts for the rest of today, 5 percent more than yesterday, according to Bloomberg’s wind model at 16:55 a.m.
Power demand is forecast to peak at 49,902 megawatts at 5 p.m. today, 6 percent less than yesterday’s maximum of 52,815 megawatts, according to National Grid data. Gas was generating 14,064 megawatts of power at 5 p.m., compared with 21,803 megawatts at the same time yesterday, grid data show.
“Wind will peak today, before slumping considerably overnight,” Byron Drew, lead forecaster at MetraWeather said in an e-mailed report. “It will then increase considerably toward the end of next week and next weekend as low pressure becomes influential.”
Wind generation is forecast to average 2,103 megawatts next week and is set to peak at 4,844 megawatts at 6 p.m. on Dec. 5, according to Bloomberg’s wind model. The U.K. got 8.2 percent or 1,952 gigawatt-hours of its power from wind in October, up from 5.8 percent the previous month, according to data compiled by Bloomberg Industries.
Power for today settled at 52.55 pounds a megawatt-hour, down 5 pounds from the previous day, in an auction on the U.K.’s N2EX exchange yesterday.
The U.K. seeks to install a total of 18 gigawatts of offshore wind farms and 13 gigawatts of onshore turbines by 2020. Current combined capacity is about 10.4 gigawatts, according to RenewableUK, a lobby group.
“We’re generating from a home-grown source which gives us a secure supply of power at cost we can control, (http://www.pic4ever.com/images/47b20s0.gif)rather than leaving ourselves exposed to the global fluctuation in fossil fuel prices which have driven bills up,” Jennifer Webber, a RenewableUK spokeswoman, said by e-mail. “Wind energy is consistently setting new records.”

Wind Testing Infrastructure Manager
Two state-of-the-art wind turbine drivetrain test facilities are now open for business: the Clemson University Wind Turbine Drivetrain Testing Facility in South Carolina and a National Renewable Energy Laboratory dynamometer at the National Wind Technology Center in Colorado. The two test facilities will be used to evaluate in a controlled environment the mechanical systems that convert the aerodynamic forces of wind turbine blades into electricity from a generator. Funded in part by the Energy Department (DOE) through the American Recovery and Reinvestment Act, the new facilities will help accelerate the development and deployment of next-generation technologies for both offshore and land-based wind energy systems.
Former Military Base Now Home to Advanced Wind Facility
Located on the site of a former Navy base with easy access to both rail and deepwater transport, the Clemson facility in North Charleston is ideal for testing the large, commercial scale turbines being developed by manufacturers for offshore wind farms. This facility, which opened last week, is equipped with 7.5-megawatt (MW) and 15-MW dynamometers that will enable the wind industry and testing agencies to verify the performance and reliability of drivetrain prototypes and commercial machines by simulating operating field conditions in a laboratory environment. Verifying a wind system's performance before it is commercially deployed reduces risk for both the manufacturer and system operator, and facilities like Clemson’s can simulate as much as 20 years’ worth of wear and tear on drivetrains in a few months.
In addition to testing the performance of the drivetrains, Clemson is using the facility's electrical infrastructure to build a 15-MW hardware-in-the-loop grid simulator. The grid simulator will mimic real-world circumstances, such as wide-area power disruptions, frequency fluctuations, voltage drops, cascading accidents, and cyber or physical attacks, to determine the effects of wind turbines on utility grids and grids on wind turbines.
Gaining Insight through Expertise
DOE's second new test facility at NREL’s National Wind Technology Center near Boulder, which also opened last week, offers industry the capability to perform accelerated tests on wind turbine drivetrains with capacity ratings of up to 5-MW. In addition, industry partners that use the facility gain access to on-site engineers with more than three decades of engineering experience.
NWTC now has two dynamometers that can be connected either directly to the grid or to a controllable grid interface (CGI). The dynamometer and CGI work in tandem to provide engineers with a better understanding of how wind turbines react to grid disturbances. With these additions, the NWTC is one of the only facilities in the world that can use these capabilities alongside operating multi-megawatt wind turbines in the field at the NWTC and energy storage devices undergoing testing there.
Watch the video above to find out how the dynamometer and the CGI work. Read this factsheet (at link below) for more information about the new NREL facility.
The two facilities are part of DOE’s overall strategy to increase the amount of electricity generated from renewable sources such as wind, reduce harmful greenhouse gas emissions, and create a more sustainable future for generations to come.

Record German Wind Power Lifts Renewable Share Over ’20 Goal (http://www.pic4ever.com/images/balloons.gif)
Rachel Morison, Bloomberg
December 06, 2013
BERLIN -- Record output from wind farms lifted Germany’s share of renewable electricity production above its 2020 target of 35 percent today as a storm from Scandinavia battered the nation’s northern coast.
A low pressure system dubbed Xaver, with hurricane-force winds of more than 140 kilometers (87 miles) an hour, hit the northern coastline of Germany today, according to the country’s weather service. Electricity produced by sun and wind supplied 27.2 gigawatts, or 36 percent, of Germany’s power at 1 p.m. Berlin time, according to the European Energy Exchange AG.
Germany is already Europe’s biggest producer of electricity from wind and sun and its newly formed coalition government agreed last month to get as much as 45 percent of electricity from renewables by 2025. (http://www.freesmileys.org/emoticons/tuzki-bunnys/tuzki-bunny-emoticon-036.gif) The share of power from wind and solar rose to 49 percent on Nov. 9, according to data compiled by Bloomberg. The average share of renewables in Germany across the whole of last year was 22 percent.(http://www.pic4ever.com/images/earthhug.gif)
“Germany might already be meeting its 2020 target for some hours, but it would need a lot more installed capacity to average 35 percent over a year,” Gary Keane, principal consultant at Poeyry Oyj, an adviser to governments and utilities, said by phone from Oxford, England.
Wind output in Germany hit a record of 25.2 gigawatts at 1:45 p.m. and will account for 39 percent of supply at 11 p.m., according to EEX data.
The strength of the storm forced turbines to shut down in some parts of Germany. (http://www.4smileys.com/smileys/seasons-smileys/storm.gif) The 48-megawatt Baltic 1 offshore wind farm operated by Karlsruhe-based EnBW Energie Baden-Wuerttemberg AG automatically halted operations at 1 p.m. when winds became too strong, Friederike Eckstein, a spokeswoman, said by phone.
“Wind turbines can start to cut out when wind goes above 60 miles an hour, so with a storm there is an increased risk of that happening,” said Keane.
German power for tomorrow declined 10.3 percent to 30.79 euros ($42.05) a megawatt hour on the Epex Spot exchange in Paris at 5:22 p.m. That’s 38.63 euros lower than the same contract in neighboring France which settled at 69.42 euros a megawatt hour, the data show.
Wind and solar power are given priority access to the grid in Germany, meaning peaks in production can force coal and gas- fed plants to reduce their output. (http://www.pic4ever.com/images/47b20s0.gif) The proportion of power produced from conventional plants is expected to fall to 61 percent at 11 p.m., compared with 79 percent at 7 a.m. today, according to EEX data.
“The storm will also bring heavy gusts of wind to the Netherlands, Denmark and Poland until tomorrow afternoon,” Andreas Gassner, meteorologist at MMInternational, said by e-mail from Appenzell, Switzerland. “Denmark and Poland could see as much as 15 gigawatts of wind until early on Monday.” (http://www.freesmileys.org/emoticons/emoticon-object-081.gif)

Global Warming Causes Severe Storms
Research Meteorologists See More Severe Storms Ahead: The Culprit -- Global Warming
January 1, 2009 — Research Meteorologists found that the temperature changes brought on by global warming are significant enough to cause an increase in the occurrence of severe storms.
Severe storms are those that cause flooding, have damaging winds, hail and could cause tornados. Their study revealed that by the end of this century, the number of days that favor severe storms could more than double certain locations, such as Atlanta and New York. Researchers also found that this increase would occur during typical stormy seasons and not during dry seasons when it may be beneficial.

(http://www.freesmileys.org/emoticons/emoticon-object-106.gif)Fact Check: IER Finds it Hard to Kick Habit of Attacking Wind Power
Elizabeth Salerno, AWEA
December 09, 2013
Like a chain smoker, the fossil fuel-funded Institute for Energy Research (IER) (http://www.pic4ever.com/images/2rzukw3.gif) seems addicted to spreading misinformation (http://www.u.arizona.edu/~patricia/cute-collection/smileys/lying-smiley.gif) about wind power.
In IER’s latest report, the fossil-fueled group claims that some states are benefitting more than their fair share from the tax relief encouraging wind power’s growth. As others have pointed out already (including the Union for Concerned Scientists and ThinkProgress), IER fails yet again.
The reality is that the wind industry provides clear economic and environmental benefits for all 50 states. Its incentive, the federal wind energy Production Tax Credit (PTC), is far smaller than the cumulative incentives provided to other energy sources, and has been so successful at driving private investment that it more than pays for itself by creating additional tax revenue.
Here’s the truth about wind power and the PTC:
1) Using tax policy to spur growth in energy sectors is nothing new
It’s important to understand that there is no comprehensive energy policy in the U.S. The reality is that much of what the U.S. has relied on to spur domestic energy growth is a collection federal, state, and local public policy techniques, including the tax code.
A new report out earlier this year, “Energy tax policy: Issues in the 113th congress” by the Congressional Research Service (CRS) makes this point clear:
“Energy tax policy involves the use of one of the government’s main fiscal instruments, taxes (both as an incentive and as a disincentive) to alter the allocation or configuration of energy resources and their use. In theory, energy taxes and subsidies, like tax policy instruments in general, are intended either to correct a problem or distortion in the energy markets or to achieve some economic (efficiency, equity, or macroeconomic) objective.”
The truth is, tax incentives for the energy sector began in 1913, when intangible drilling costs were given to the oil industry and dozens have been added since then, most of which support fossil fuels. In fact, the Nuclear Energy Institute’s own tally concludes that federal subsidies to fossil and nuclear energy sources totaled more than $650 billion from 1950 to 2010. Despite their remarkably long life spans, such incentives are mostly ignored (http://www.createaforum.com/gallery/renewablerevolution/3-311013201314.png) in the current energy debate.
Had the study looked at the more than $650 billion in federal support for fossil and nuclear energy over the last 60 years, it would have found the benefits and costs of that to be very unevenly distributed because only a few states produce the majority of those fuels, while all other states get the triple whammy of having to pay for the subsidy, having to send money to those states to buy the fuel, and then getting stuck with the pollution in their states.
And while other industries continue to receive tax incentives carrying an expensive price tag, the PTC more than pays for itself in local, state, and federal taxes over the life of wind power projects according to a NextEra Energy analysis.
2) All 50 states benefit from wind power equipped with the PTC
IER’s report strategically ignores the NextEra analysis demonstrating that the PTC more than pays for itself in addition to the sizable economic benefits wind power has produced in all 50 states.
Wind power generated $25 billion in private investment, paying millions to landowners and local communities. Every state in the union, including 70 percent of all U.S. congressional districts, has an operating wind project, manufacturing plant, or wind-related jobs.
All online wind energy related manufacturing facilities and wind energy projects, by Congressional Districts.
Wind energy is one of the most broadly dispersed energy industries, with manufacturing currently in 44 states and turbines installed in 39 states plus Puerto Rico.
U.S. Wind energy Capacity Installed by State
In fact, “Made in the USA” is now a label American wind power can proudly display on a majority (over 70 percent) of its parts and supplies. ;D
American wind power supports 80,000 full-time jobs and according to a Department of Energy analysis, with the right policies in place, wind power could support 500,000 full-time domestic jobs by 2030.
Wind energy brings taxes and other revenues to rural communities, benefiting county and local services, schools, and health care and public safety facilities. Plus, land lease payments to rural landowners, farmers, and ranchers hosting America’s new drought-resistant cash crop often total millions of dollars in states across the country.
WIND leases are FOREVER;(http://www.createaforum.com/gallery/renewablerevolution/3-141113185701.png)
Fracking LEASES are temporary and pollute your LAND!(http://www.desismileys.com/smileys/desismileys_1593.gif)
3) Wind energy is reducing electricity prices across the country
More than a dozen studies by grid operators and state governments have confirmed that wind energy reduces electricity prices by displacing more expensive sources of energy. That includes a recent report by Synapse Energy Economics that found that doubling the use of wind energy in the Mid-Atlantic and Great Lake states would save consumers $6.9 billion per year on net, after accounting for both wind and transmission costs.
Because the electric power system is a highly integrated network, many of these electricity price reduction benefits accrue to states that have little to no wind energy. For example, the Synapse study found that the $6.9 billion in benefits of wind energy would be broadly spread across the 13 Mid-Atlantic and Great Lakes states, even to states without wind energy, as wind plants allow fossil-fired power plants in other states to reduce their output and fuel use. These interstate consumer benefits of wind energy are even more clear when utilities buy wind energy from other states. For example, Southern Company’s Georgia and Alabama utilities have made three large purchases of wind energy from Oklahoma and Kansas, explaining that those purchases reduce its customers’ electric bills. (April 22, 2013 press release)
4) Environmental benefits from wind power are also spread across all 50 states
Another goal of the PTC was to establish better U.S. energy security and address concerns about the environment. As the 2013 CRS report notes:
“The U.S energy tax policy as it presently stands aims to address concerns regarding the environment as well as those surrounding national security. Incentives promoting renewable energy production, energy efficiency and conservation, and alternative technology vehicles address both environmental and national security concerns. Tax incentives for the domestic production of fossil fuels also promote energy security by attempting to reduce the nation’s reliance on imported energy sources.”
Adding wind power displaces the most expensive, least efficient power source on the utility system — usually an older fossil fuel plant. The total wind power installed today now allows us to avoid the equivalent of 100 million metric tons of CO2 annually — the equivalent of taking over 17 million cars off the road.
Wind power uses no water to generate electricity, while most other types of power plants use substantial quantities.Installing over 60 GW of wind power has resulted in saving the equivalent of 37 billion gallons of water annually. That’s 130 gallons of water per person. (http://www.freesmileys.org/emoticons/emoticon-object-103.gif)
Wind energy does not emit particulate matter, which is associated with heart and lung disease, and it also does not emit mercury or other heavy metals, which collect in the food chain and are harmful to human and animal health.
In fact, according to a report completed for the New York State Energy Research and Development Authority (NYSERDA), wind power has the lowest impact on wildlife and the environment of any of several technologies studied — including coal, oil, natural gas, nuclear, and hydropower.

The bipartisan support that the PTC has historically received has been a reflection of Congress understanding that the majority of American people want more wind energy. With all these economic and environmental benefits, it’s easy to understand why that overwhelming support exists.
IER’s best (worst) efforts will not change these facts. (http://www.pic4ever.com/images/128fs318181.gif)(http://www.desismileys.com/smileys/desismileys_0293.gif)

December 10, 2013
FRANKFURT -- EWEA’s biannual offshore wind conference and exhibition took place between 19 – 21 November in Frankfurt, Germany. International exhibitors and visitors could be clearly subdivided into typical marine and wind-industry related and additional companies and organizations offering specific products and dedicated offshore wind services such as a supersize HVAC submarine cable and several new foundation solutions.
ThyssenKrupp Mannex of Germany for instance presented a clever and innovative jacket foundation called Hexabase, described as the first industrial solution for offshore wind. The large-diameter open lightweight structure consists of so-called bionic elements, standardized pipes and pre-cast nodes, all of which mean a high automation level.
Here's a look at some new turbine product developments.
Samsung of Korea had a prominent display at the show with a large booth dedicated to the 7-MW S7.0-171 offshore turbine, a prototype of which was recently installed in the UK. The behemoth is designed for 25-year operating life and features the world’s longest 83.5-metre blades offering a record 171.2-metre rotor diameter. The compact medium-speed drivetrain comprises a two-stage planetary gearbox designed and built by UK firm David Brown. A rather unusual design feature is that the gearbox has been integrated inside the large-diameter hollow main shaft, which in turn is supported by two rotor bearings.
The medium-voltage permanent magnet generator (PMG) operates at 3.3kV, and all power electronics including power cabinets, power-electronic converter, MV-transformer and switchgear are located in the tower base. According a Samsung spokesperson the turbine can achieve 73 percent capacity factor at high-wind sites. The S7.0-171 under such conditions generates at 63 percent of the time measured over the year over 80 percent of its rated power, qualifying it as a “true power plant.” The company expects to receive certification in 2014.
Power engineering specialist ABB introduced a new 7-MW high-speed permanent magnet generator in Frankfurt. The generators come available in low voltage (690V) and medium-voltage (3.3kV, and either water or air-cooled. All ABB high-speed generators for wind turbines (DFIG, PMG and induction-type) are based on a standard modular platform principle and feature an adaptable turbine interface. The modularity also allows changing from DFIG to PMG and vice versa depending upon customer preferences. Developing a new high-speed generator in the 7-MW high-end capacity range could come a bit as a surprise, because most new super-class geared turbine developments now seem to focus at medium-speed solutions.
REpower of Germany introduced the long-awaited successor to its 6.15-MW 6M (2009) flagship model, a product platform history that commenced in 2004 with a pioneering 5-MW 5M turbine, both with 126-metre rotor diameter. The new offshore model technologically builds on the 6M (now renamed 6.2M126, pictured above) and comes with unchanged power rating. New main features include the switch to a load-optimized cast main chassis and an enlarged 152-metre rotor diameter. This offers 46 percent more rotor swept area and, according Repower, a 20 percent higher yield at 9.5 percent average wind speed sites. The new slender blades are a dedicated REpower in-house product development. The 6.2M152 incorporates again a high-speed geared drivetrain with DFIG and 6.6kV stator voltage. 66kV transformer output voltage is now optional and is expected to become a new offshore wind standard for intra-array wind farm cabling.
Two-bladed and Downwind
German engineering consultancy aerodyn based in Frankfurt introduced an innovative two-bladed 8-MW SCD 8.0 down-wind offshore turbine with 168-metre rotor diameter. (SCD stands for Super Compact Drive.) The SCD 8.0 incorporates a medium-speed drivetrain with a single rotor bearing flanged to an in-house developed planetary gearbox plus PMG. These main components in turn are flanged directly to a cast main carrier, and there is no separate nacelle cover.
One special product feature of the SCD 8.0 is a helicopter-landing platform integrated in the nacelle upper part, whereby actual landings are enabled only after locking the rotor in horizontal position. (See image, left, for an example of the 3-, 6-, and 8-MW products.)
Two-bladed turbines are new in the offshore market, but do offer specific advantages including easier deck stowage of fully assembled turbine heads (nacelle + rotor) plus time and cost-saving single-hoist installation. The SCD 8.0 is aimed at the European offshore market, and aerodyn owner/director Sönke Siegfriedsen firmly believes that a favorable 395-tonne head mass makes the turbine well-suited for both seabed-fixed and floating foundations solutions.
SCD 8.0 is a further development and optimization of the 6-MW SCD 6.0, an IEC class IIB turbine featuring 140-metre rotor diameter. Aerodyn’s Chinese partner and licensee Ming Yang is currently testing the SCD 6.0 prototype, with installation planned for early 2014. The SCD 6.0 was specifically developed for the hurricane-prone coastal stretch between Shanghai and Hong Kong, which, according aerodyne, is one of the world’s largest future offshore wind markets. Ming Yang already operates several 3-MW two-bladed onshore upwind SCD 3.0 turbines with 110-metre rotor diameter for IEC class IIIA locations. (See image, right, for an example of an onshore two-bladed turbine.)
SCD was first presented at the 2007 Husum wind industry fair and was one of the world’s first medium-speed turbine designs.
SCD technology is built upon aerodyn’s (design) experiences with its patented 5-MW hybrid-type offshore turbine called Multibrid M5000. This groundbreaking turbine was developed and patented during 1996/7 and is comprised of a single rotor bearing and a highly compact fully enclosed cast chassis that incorporates a single-stage planetary gearbox and permanent magnet generator.
AREVA Wind commercialized the M5000-116, and an optimized 5-MW M5000-135 prototype with enlarged 135-metre rotor was installed this autumn.
Siemens Energy finally presented its new 4-MW and 6-MW offshore turbines in Frankfurt, including a new 4-MW SWT-4.0-120 model version with 120-metre rotor diameter. The company said that it wants to reduce lifecycle-based cost of energy (CoE, which equals turbine cost/kWh/20-25y) for both the 6-MW direct drive and 4-MW geared turbine models by up to 40 percent compared to today’s levels.
Substantially reducing CoE remains the offshore wind industry’s main overall challenge for the future of offshore wind power, and is a huge task ahead for all parties involved. Achieving this goal requires sustained combined efforts from project developers to wind turbine and submarine cable installation vessel designers/suppliers, foundation designers/manufacturers, advanced transport-logistics, installation contractors, and wind farm upkeep specialists.

Fossil fuelers are handicapped by hydrocarbon tunnel vision. But most people no longer see things their way. Moreover, since more and more people are making a LIVING off of RENEWABLE ENERGY and less and less people are making a living from fossil fuels, the dirty energy will get pushed out.
Fossil Fuels should have been pushed out in the 1980s. This time they will be. 8)
Here's some more reaiity based community information fossil fuelers refuse to acknowledge. (http://www.pic4ever.com/images/301.gif)
Major Shipyard Now building MORE Renewable Energy machines than ships!
Imagine how quickly we could transition if the over 400 OIL TANKERS the Oil Industry builds EACH YEAR, were NOT BUILT and WIND TURBINES were built instead! That's a LOT of wind turbines and tidal or ocean current turbines! (http://www.createaforum.com/gallery/renewablerevolution/3-141113185701.png)
Oil Tanker costs:
DWT= DEAD WEIGHT TONNAGE CAPACITY
LR2 (Large Range 2), Suezmax class,120,000–200,000 DWT, $60.7M
VLCC (Very Large Crude Carrier), VLCC class, 200,000–320,000 DWT, $120M
ULCC (Ultra Large Crude Carrier), Ultra Large Crude Carrier class, 320,000–550,000 DWT, $120M PLUS
Now suppose you wanted to build 100 of those pigs at an average price of $100M or so (they're cheaper by the dozen!).
$100,000,000 X 100 = $10B
How many wind turbines can we buy with that $10B INSTEAD OF TANKER PIGS?
Here's a nice wind turbine outfit that is ALREADY kicking fossil fuel ass! Maybe we can do business with them. (http://www.createaforum.com/gallery/renewablerevolution/3-141113185047.png)
As of 2011, Vestas wind turbines generate enough electricity to provide for 21 million people. In January 2011, Vestas won the $1.5m (£940,000) Zayed Future Energy Prize in Abu Dhabi. (http://www.clker.com/cliparts/c/8/f/8/11949865511933397169thumbs_up_nathan_eady_01.svg.hi.png) ;D
Nice video! Too bad they didn't have to turbines spearing oil tankers as they surfaced! (http://www.pic4ever.com/images/128fs318181.gif) ;D
Using the information at the link below, you can get a bunch of the top of the line Vestas 8MW (formerly the 7M just two years ago but has been tweaked up) for around $8M if we order more than 300 MW worth of turbines (Yes, those are cheaper by the dozen TOO! (http://www.freesmileys.org/emoticons/emoticon-animal-042.gif)).
That means we can buy about ONE THOUSAND turbines for the price of 100 oil pig tankers. (http://www.clker.com/cliparts/c/8/f/8/11949865511933397169thumbs_up_nathan_eady_01.svg.hi.png)
Those 1,000 turbines will generate 8 GW of power near continuously because they will be placed offshore, to MKing's chagrin. ;D But don't worry, they have maintenance and some slack wind periods from time to time so you fossil fuelers can claim they are "discontinuous, unreliable and no good for baseload". (http://www.pic4ever.com/images/ugly004.gif)
But let's not stop there. The fossil fuel industry has enough capital to build 400 tankers in a single year so they technically have enough capital to build 4000 wind turbines producing 32 GW EACH YEAR. :o Consider, for a moment, what adding 32GW of renewable energy would DO to the energy picture of this planet. (http://us.123rf.com/400wm/400/400/yayayoy/yayayoy1106/yayayoy110600019/9735563-smiling-sun-showing-thumb-up.jpg)
Now consider that world governments have even more capital. Consider that adding ten times that much (320 GW each year) from various renewable energy technologies is feasible simply because there are several large wind turbine and ocean current and tide turbine manufacturers just as capable as Vestas of pumping out 4,000 8MW turbines a year (GE can make even more than Vestas).
And then there is solar PV and power towers and geothermal along with all sorts of energy storage technologies that, unlike oil tankers, don't spill their guts into the oceans on a regular basis and will provide 24/7 smooth power access to customers, regardless of what the nasty, negative, naysayers among us that will mendaciously claim otherwise as long as their portfolio has dirty energy stocks in them. (http://www.freesmileys.org/smileys/smiley-scared002.gif)
Within a couple of decades we could stop burning fossil fuels completely as long as we stuck to the current 18TW annual human civilization energy demand. (http://www.pic4ever.com/images/balloons.gif)
No more strip mining for coal or drilling for oil or fracking for oil and gas messing up our biosphere.
Consider what having 34% LESS ocean traffic and NO oil tankers or oil rigs would do for the health of the oceans.
Dear readers, always remember to remind the fossil fuelers a little item they ALWAYS seem to forget. And that is, that they DO NOT have an ESTABLISHED industry and a "going concern proven business model" as they claim because
A) They are massively subsidized
B) They are CONSTANTLY replacing equipment that lasts, at most, a couple of decades. At any moment they can decide to buy the renewable energy machines instead of fossil fuel transport and drilling equipment on the same schedule of replacement that they use to replace oil rigs, tankers, etc. BUT THEY REFUSE TO DO SO. (http://www.createaforum.com/gallery/renewablerevolution/3-311013201314.png)
Can you say, Mens Rea? >:(
At any rate, the shipyards are catching on that building Renewable Energy Machines provides more and better jobs than building polluting tanker pigs. GOOD!
Harland & Wolff Heavy Industries is a Northern Irish heavy industrial company, specialising in shipbuilding and offshore construction, located in Belfast, Northern Ireland.
The shipyard has built many ships; among the more famous are the White Star trio RMS Olympic, RMS Titanic and Britannic, the Royal Navy's HMS Belfast, Royal Mail Line's Andes, Shaw Savill's Southern Cross and P&O's SS Canberra. The company's official history, Shipbuilders to the World, was published in 1986.
As of 2011, the expanding offshore wind power industry has taken centre stage and 75% of the company's work is based on offshore renewable energy.
... the United Kingdom planned to build 7,500 new offshore wind turbines between 2008 and 2020, creating great demand for heavy assembly work.
Unlike land-based wind turbines, where assembly occurs on site, offshore wind turbines have part of their assembly done in a shipyard, and then construction barges transport the tower sections, rotors, and nacelles to the site for final **** and assembly. As a result of this, in late 2007, the 'Goliath' gantry crane was re-commissioned, having been moth-balled in 2003 due to the lack of heavy-lifting work at the yard.
In June 2008, assembly work at the Belfast yard was underway on 60 Vestas V90-3MW wind turbines for the Robin Rigg Wind Farm. This was the second offshore wind farm assembled by the company for Vestas having completed the logistics for the Barrow
Offshore Wind Farm in 2006. In August 2011 Harland and Wolff completed the logistics for the Ormonde Wind Farm which consisted of 30 REpower 5MW turbines.
In March 2008, the construction of the world's first commercial tidal stream turbine, for Marine Current Turbines, was completed at the Belfast yard. The installation of the 1.2MW SeaGen Tidal System was begun in Strangford Lough in April 2008.
In July 2010, Harland & Wolff secured a contract to make a prototype tidal energy turbine for Scotrenewables Ltd. Manufacture of the SR250 device was completed in May 2011 and has been undergoing testing in Orkney since.
As of April 2012, the booming offshore wind power industry has taken centre stage. Harland & Wolff are currently working on three innovative meteorological mast foundations for the Dogger Bank and Firth of Forth offshore wind farms, as well as putting the finishing touches to two Siemens substations for the Gwynt y Môr offshore wind farm. Seventy-five per cent of the company's work is based on offshore renewable energy.
Harland & Wolff is one of many UK and international companies profiting from the emergence of UK wind- and marine-generated electricity, which is attracting significant inward investment.

Wind energy becoming cheaper than natural gas :o
By John Upton
In the blustery Midwest, wind energy is now coming in even cheaper than natural gas. From Greentech Media:
“In the Midwest, we’re now seeing power agreements being signed with wind farms at as low as $25 per megawatt-hour,” said Stephen Byrd, Morgan Stanley’s Head of North
American Equity Research for Power & Utilities and Clean Energy, at the Columbia Energy Symposium in late November. “Compare that to the variable cost of a gas plant at $30 per megawatt-hour. …”
Byrd acknowledged that wind does receive a subsidy in the form of a production tax credit for ten years at $22 per megawatt-hour after tax. “But even without that subsidy, some of these wind projects have a lower all-in cost than gas,” Byrd said.
And the gas industry certainly gets plenty of its own subsidies. >:(
Wind is also breathing down the neck of the coal industry in the region: ;D
Wind is even going head-to-head with Powder River Basin coal. “In the Midwest, those wind plants are, many times of the day, competing against efficient nuclear plants and efficient PRB coal plants,” Byrd said.
Oh yeah, nuclear. As we reported earlier this year, wind is threatening nuclear too. (http://www.pic4ever.com/images/47b20s0.gif)
While wind and solar farms can be expensive to build, Byrd points out that the fuel for them is free, giving them an edge in the country’s competitive electricity markets. (http://www.pic4ever.com/images/19.gif) (http://www.pic4ever.com/images/128fs318181.gif)

With a wind PTC expiration potentially days away, expect more deals like this one to get projects qualified under the gun.
James Montgomery, Associate Editor, RenewableEnergyWorld.com
December 16, 2013
New Hampshire, USA -- We're just days away from the end of calendar 2013, which means a number of annual rituals: holiday parties, lists of top-everything-whatever -- and angst over the expiring production tax credit (PTC) that has been key to the U.S. wind industry's growth. ??? >:(
Last year's PTC was ultimately extended at the 11th hour, and its language tweaked this spring changing the requirements that a power plant must be online to requiring that a plant be "under construction" either through physical work being done or the developer having incurred 5 percent of the total cost. With the PTC's expiration looming one again, look for some last-minute announcements as wind developers try to get some projects nailed down.
And now we have Exhibit A: (http://www.clker.com/cliparts/c/6/7/1/12065737551968208283energie_positive_Wind_Turbine_Green.svg.hi.png)MidAmerican has ordered 1 GW of turbines from Siemens AG for its five planned new wind farms in Iowa scheduled to come online in 2015, spanning sizes of 44 MW up to 500 MW, adding to the roughly 2.3 GW the company already operates in the state. The blades will be built in Siemens' Fort Madison, Iowa plant and the nacelles and hubs will be assembled in Hutchinson, Kansas. With these turbine investments, those projects officially qualify for the PTC as it currently exists, according to Adam Wright, VP of wind generation at MidAmerican.
About half of that collective 1 GW of new Iowa wind capacity is expected to be installed by the end of 2014, with the "civil work" completed for the remaining 500 MW, which will add turbines and come into service in 2015, Wright explained. But in a surprise, he also revealed that the 44-MW Vienna II expansion originally slated to be completed in the fall of 2014 has already begun commercial operations -- it came online on December 4, to take advantage of the current PTC's bonus depreciation. (http://www.createaforum.com/gallery/renewablerevolution/3-051113192052.png) (http://www.websmileys.com/sm/violent/sterb029.gif)
MidAmerican and Siemens will broadcast all this news live at 1 pm Central Time today; watch it here or on AWEA's home page.
Iowa is one of the leading U.S. state adopters of wind energy, getting nearly a quarter of its total power generation from wind in 2012. It ranked third in the nation for MW installed (5.1 GW) and number of wind turbines (3,200). The Iowa Wind Energy Association projects 10 GW of installed capacity in the state by 2017, with a statewide potential of 570 GW.
UK Approves 450 Million Pound Offshore Wind Port Project Plan
Alex Morales, Bloomberg
December 18, 2013
LONDON -- The U.K. approved a 450-million pound ($736 million) project to build manufacturing and port facilities for the offshore wind industry in northeast England, expanding the country’s drive to develop the technology. ;D
Able U.K. Ltd. was given the go-ahead for the project after satisfying a government request for more detail on how it will accommodate for seabirds and a railway line affected by the plan, the Department of Transport said today in an e-mailed statement. Parliament must now consider compulsory purchase powers to acquire some of the land needed, it said.
Britain has more installed offshore wind power than the rest of the world combined, and ministers have identified the technology as key to U.K. efforts to slash carbon and boost renewables. Deployment of 10 gigawatts, almost triple current installations, is possible by 2020 ;D, according to the government, which has shied away from setting an official goal.
The approval is “testament to a continuing sense of long- term confidence in the offshore wind sector, which is at the very heart of our green energy future,” Maf Smith, deputy chief executive officer of the RenewableUK lobby group said in a statement. “Offshore wind, and the supply chain it is building, could create tens of thousands of green-collar jobs to coastline communities in areas where they’re needed most.”
The project on the banks of the Humber River in northeast England includes about 1,300 meters (4,300 feet) of deep-water docks and 906 acres (367 hectares) of land for offices and factories, according to its website. Able says the project may create 4,000 jobs.
It’s designed to be used by offshore wind project developers that need to deploy large components such as foundations and wind turbine towers and nacelles to their sites at sea. The intention is for the first dock to be available for use in 2016.
“It provides the opportunity, not available at any other U.K. location, to create a critical mass of activity,” Able Executive Chairman Peter Stephenson said today in a statement. “The Humber is ideally placed in close proximity to the world’s largest proposed offshore wind farms.”
Able Marine Energy Park on Dec. 9 signed a memorandum of understanding with Strabag SE’s Stuttgart, Germany-based offshore wind unit identifying it as the company’s preferred location to build a factory for the mass production of foundations for offshore wind turbines, with the potential to create up to 500 jobs.

Renewable Energy could "NEVER" fill the gap because
1) It is TOO EXPENSIVE AND HAS TOO LOW AN EROI. (http://www.u.arizona.edu/~patricia/cute-collection/smileys/lying-smiley.gif)
2) It can't provide baseload power due to "intermittence". (http://www.createaforum.com/gallery/renewablerevolution/3-241013183046.jpeg)
3) Forced lessening of total energy use will impair the economy drastically because GDP ALWAYS tracks total energy use!
4) Renewable Energy cannot be deployed quick enough to avoid a collapse.(http://www.freesmileys.org/smileys/smiley-scared003.gif)
WELL, both "1)" and "2)" have been proven FALSE.
As to "3)" we have already proved that is false in the last 13 years.
HOW DID WE DO THAT? According to Amory Lovins of the RMI, US GDP is 25% higher than in the year 2000 and we use MUCH LESS TOTAL ENERGY!
BUT, ya never know... Item "4)" may still happen,,, 8)
I say that IF IT DOES HAPPEN, it will have NOTHING to do with energy and be solely climate catastrophe caused. :P
6 Reasons Why Nuke Fan Is Dead Wrong About Wind Energy
American Wind Energy Association | December 7, 2013 11:45 am
By Michael Goggin
The Energy Collective blog recently carried a column, Limitations of Unreliable Energy Sources, aka ‘Renewables,’ by Rod Adams, a longtime nuclear power advocate and critic of competing energy sources. In his column, Adams repeats a number of false statements about wind power.
When corrected, his claims actually highlight a number of ways in which wind energy’s efficiency is superior to that of other energy sources.
Wind energy significantly reduces carbon emissions and does not noticeably reduce the efficiency of fossil-fired power plants on the utility system.
Recent analysis of the impact of wind on the efficiency of fossil-fired power plants found that with renewable energy supplying 33 percent of the electricity, wind produces 99.8 percent of the expected fuel use and carbon dioxide (CO2) emissions savings after accounting for all cycling impacts, or savings of 1,190 pounds of CO2 per megawatt hour (MWh) of wind. This analysis is based on real-world hourly emissions data for all fossil-fired power plants in the Western U.S, and puts to rest the fossil fuel industry myth that wind energy’s emissions savings are lower than expected.
Transmission pays for itself through economic and reliability benefits.
Numerous studies show that grid upgrades more than pay for themselves through the reliability and economic benefits they provide to consumers. The claim that a significant amount of wind energy is lost in transmission to consumers is false, as almost all line losses occur on low-voltage distribution lines, and thus apply to all energy sources evenly (page 30).
Wind energy has a lower integration cost than large conventional power plants.
Every wind integration study has found that there is more than enough flexibility on the power system today to accommodate very high levels of wind energy. In contrast, the need for reserves to accommodate the sudden failure of conventional power plants is far larger and many times more costly than for wind (see calculations in footnotes 6 and 7). Adding wind energy to the grid does not cause any need for new power plant capacity, and actually significantly reduces the total need for power plants.
Wind energy curtailment has only occurred due to localized transmission constraints (that are being eliminated), and never because the amount of wind output exceeded total demand on the power system.
Even the curtailment caused by localized transmission congestion is being eliminated as long-needed grid upgrades catch up with wind energy’s rapid growth, with curtailment cut in half from 2011 to 2012. (see page 44) Further declines are occurring in 2013, with curtailment on the ERCOT (Electric Reliability Council of Texas) system now approaching zero.
Onsite energy use is far higher at conventional power plants, on the order of 7 to 15 percent of power plant energy production.
In contrast, the figure for wind plants is typically far less than 1 percent. A comprehensive literature review of all peer-reviewed studies on the lifecycle carbon emissions impacts of all energy sources demonstrates that wind’s impact is a fraction of all conventional energy sources, and is also much lower than most other renewable energy sources.
Energy storage is not needed for wind energy.
The U.S. has added 60 gigawatts (GW) of wind, and Europe even more, with zero need to add energy storage. As explained above, there is plenty of flexibility on the existing power system. Interestingly, nearly all of the 22 GW of pumped hydro energy storage in the U.S. was added to help accommodate the inflexibility and additional reserve needs imposed by large nuclear power plants.
Finally, it seems strange to talk about the efficiency of different energy sources without discussing the fact that most fossil and nuclear power plants immediately waste 2/3 of the energy in their fuel as waste heat at the power plant, while most modern wind turbines capture around 50 percent of the energy available in their fuel. The U.S. Department of Energy’s data on the average efficiency of different types of power plants is here:
•Coal: 32.7 percent efficiency
•Gas: 41.9 percent efficiency
•Nuclear: 32.6 percent efficiency
Siemens to Supply Turbines for $2.6 Billion :o Cape Wind Project
Ehren Goossens, Bloomberg
December 24, 2013 | 2 Comments
NEW YORK CITY -- Siemens AG, Europe’s biggest engineering company, agreed to supply turbines to the $2.6 billion Cape Wind project, the first offshore wind farm planned in the U.S.
Siemens will install 130 of its 3.6-megawatt turbines at the facility that’s now seeking finance for construction in Massachusetts waters, the Munich-based company said today in a statement. Financial details of the agreement weren’t disclosed.
The deal along with a proposal from Siemens to take a $100 million equity stake in the project raises the chances that the project will move forward. Residents including the family of former President John F. Kennedy have sued to stop the project, ??? >:( saying it will spoil a uniquely beautiful area.
“Siemens will most likely be an investor in the project,” Randy Zwirn, chief executive officer of SiemensEnergy Inc., said in an interview.
Siemens, the largest supplier of offshore wind turbines, said the deal is subject to final negotiations. Its 3.6 megawatt turbine is the most installed offshore turbine in the world, Jim Gordon, founder and owner of Boston-based Energy Management Inc., the parent of Cape Wind, said in an interview.
“Because it’s the first offshore wind farm in America, it was very important for us to pick the workhorse of the offshore wind industry,” Gordon said.
Siemens said last week that Cape Wind is likely to qualify for a tax credit that expires at the end of this year. It has faced delays due to lawsuits opposing it.
“The process was careful and deliberate, and we fully expect our permit will be upheld,” Gordon said. “We fully anticipate the legal decision our way simply because this has been one of the most comprehensively reviewed energy projects in decades in the United States. They’ve been using these avenues as a delaying factor.”
The Interior Department has said about 1,000 gigawatts of potential wind energy exists off the U.S. Atlantic coast, though no projects have been completed. Several, including the Block Island project are moving forward as well.
The U.S. awarded a lease to Cape Wind Associates LLC in 2010 for an area 5 miles (8 kilometers) off mainland Cape Cod. It’s spread over 25 square miles known as Horseshoe Shoal and would generate on average enough electricity to power 200,000 homes, according to the Energy Department.
“This is really the first offshore wind project of any significance anywhere in the U.S.,” Zwirn said. “As the leading supplier of offshore wind turbines in the world, we obviously have an interest to see that market potential to be developed.”
Warren Buffett’s Berkshire Hathaway Inc. unit MidAmerican Energy Holdings Co. awarded Siemens, whose largest business is energy, on Dec. 16 with a more than $1 billion contract, the largest ever, for 448 turbines for wind farms in Iowa.

Subsea Cables Bring Offshore Wind Power to the People
Cables are increasingly recognized as a crucial aspect of wind farm construction and operation. Here, we offer a glimpse of a Norwegian subsea cable manufacturing facility and review the challenges of this evolving market.
Tildy Bayar, Contributing Editor
December 19, 2013
LONDON -- It might be surprising to learn that Norway’s tallest building is Nexans’ 120-metre extrusion tower at the company’s submarine high-voltage direct current (HVDC) cable factory in Halden. Nexans makes subsea cables that connect offshore wind farms to the grid, transports them around the world and installs them underwater so that the cables can bring clean power from offshore wind farms to onshore substations and from there to our homes.
Several different types of cable are used in offshore wind projects. Low (up to 1 kV) and medium-voltage loop cables transmit the electricity produced in the turbine’s generator to the transformer, usually located at the tower’s base. Then array cables connect the turbines on a wind farm to each other and export cables carry their power to the grid. Finally, underground and overhead line (OHL) cables that make it all work on land.

On a recent tour of the factory, sponsored by Nexans, guides explained that the high tower at the Nexans factory houses the vertical extrusion machinery that begins the cable-making process. From “clean rooms” at the top of the tower, superclean polyethylene and cross-linkable, super-smooth “semicon” are fed through a closed system of huge tubes back down to an extruder at ground level, where the conductive material and insulation are spit out simultaneously from multiple extruders that feed into a single head. The tower can produce 15 km of cable in one week before the workers have to stop the process to change the enormous receiving baskets.
The height of the tower is important because all of the heat must be removed from the materials before they enter the tube. Curing and cooling takes place in a dry atmosphere of pressurized nitrogen in the building before the materials are fed from the tower to various stations in other buildings through “cable ways” which are little wheeled tracks running across and between buildings.
Using copper, aluminum, lead and wire, the materials are formed into cable lengths weighing up to 400-500 kg. At the end of the process the lengths are combined using proprietary joints to make 60-70 km cables.
After several more processes involving insulation and strengthening of the cables, they are tested for resilience and torsion. As a wind turbine’s nacelle rotates, the cables are severely twisted, so they must be extremely resistant to both torque and vibration. The torsion tests on cables simulate 20 years of use in a wind installation. Nexans said the exact test applied to a given cable depends on the customer’s specifications.
A Challenging Market
The wind industry’s move to deeper waters is challenging, according to Nexans, because transport vessels can only hold so much cable. Nexans’ flagship transport and laying boat, the Skagerrak, holds 50 tons of cable on its built-in turntable. The Skagerrak can accommodate 65 workers and has travelled all over the world. Not many vessels can hold its capacity, according to the company, and there are just one or two others in the world including the Giulio Verne, belonging to Nexans’ main competitor Prysmian.
The Nexans "Capject" can dig trenches in soft or hard sediments, according to the comany, and is able to operate in depths of up to 1,000 meters. Credit: Nexans.
With wind farms moving further offshore, said Vincent Dessale, chief operating officer of the submarine high voltage business line, Nexans’ customers are seeking increasingly higher transmission capacity, which means producing larger and longer cables. The Halden plant ran into problems in 2012, with an invoice delay in submarine cables leading to a drop in Nexans stock and an eventual restructuring of the business. The company has learned some lessons, it said, including that “feeding in more machines and manpower to match market demand is not sufficient” and that “coping with growing complexity and increasing timeline uncertainty requires highly structured organization, robust processes and the right mindset,” said Dessale.
Another challenge is that cables are becoming increasingly important in risk management. “One of the key differences between offshore and onshore wind farms, at the concept and design phase is the need to consider cable failure when designing the electrical architecture,” said David McNaught, senior engineer at consultancy Frazer-Nash. “If a submarine cable fails in service the consequences for the operability and profitability of the wind farm could be dire; especially if there are delays in securing a suitable repair vessel or if weather conditions are severe, likely during the winter months.
“It is essential that the electrical cable systems of wind farms have high reliability – that the system has the ability to withstand unforeseen circumstances,” McNaught continued. Cable risk is a relatively new aspect of wind project financial analyses, he said, but it is increasingly being considered – to the point where new guidelines from GL Renewables Certification, published in January, include on-site and power export cables. To address this growing concern, Nexans said it has scaled up risk analysis at the tendering stage and the company is working to develop and implement risk mitigation before beginning production.
Another challenge is transport for larger and longer cables. The current Skagerrak, the third in its line and 130 km, was built in 1993; the Skagerrak 4, which is expected to be complete in 2014, will be 140 km.

The market is growing in complexity, too, said Dirk Steinbrink, executive vice president for high voltage and underwater cables. The project scope of Nexans’ work has expanded to offer not just cables but turnkey interconnection solutions, he said.
On the Northwind project, which is expected to be completed before the end of 2013, Nexans is contracted to supply cables to connect the Belwind 2 offshore wind farm to Northwind, and Northwind to the shore. The project’s scope includes cable design, testing, supply, jointing termination work and on-site testing (called cable witnessing). The company said that it would use the largest cable ever manufactured at the project site, a 1-meter wide, 30-kg behemoth.
Offshore wind farm developers must also consider the social impact of the installation process. “The acceptance level from people living [near a site] is quite low,” ??? >:( Steinbrink said. “They like green energy but don’t want to see us doing the work. So we do micro-tunneling, especially in places with tourism.” (http://www.clker.com/cliparts/c/8/f/8/11949865511933397169thumbs_up_nathan_eady_01.svg.hi.png) ;D
Frédéric Michelland, senior executive vice president for high voltage and underwater cables, North and South America, does not expect the market for wind turbine cables to evolve dramatically over time. Today, he said, Nexans covers 80 percent of the European market, while “tomorrow that will move to North America and China – but we expect our market to remain largely European.” In Europe there are “still plenty of projects where most of the action will take place,” he said.

American Wind Energy Association | December 13, 2013 4:09 pm
By Bentham Paulos
Renewable electricity records are being broken every day. In early October, Germany hit a 59 percent renewable peak, Colorado utility Xcel Energy peaked at 60 percent wind at the beginning of the year and Spain got its top power supply from wind for three months leading into 2013.
But that’s chump change compared with Denmark. According to data from Energinet, the national grid operator, wind power has produced 30 percent of gross power consumption to date in 2013. This includes more than 90 hours where wind produced more than all of Denmark’s electricity needs, peaking at 122 percent on Oct. 28, at 2 a.m.
And Denmark has plans to get to 50 percent more wind by 2020, creating even bigger hourly peaks. Energinet predicts the country may hit as many as 1,000 hours per year of power surplus.
To champions of renewables, this is validation that a clean energy future is possible and that the transition is already underway. These regions also give insight into what is to come in the U.S., and what needs to change to keep a reliable and affordable power system as clean energy grows.
Postcards from the future
As part of America’s Power Plan, we have developed a series of “postcards from the future,” describing places like Denmark that are already grappling with a high-renewables future.
Studies and real-world experience are underscoring that there are many tactics available to deal with the variability of wind and solar, and that these tactics are largely substitutes for each other.
While energy storage comes to mind first for many people, the truth is that the grid has functioned just fine with very little storage. Power system operators have to deal with variability all the time, with or without renewables. Demand fluctuates with the weather, time of day, social activities, and industrial operations. And supply varies unexpectedly too, such as when a power plant breaks down. The fluctuations of wind and solar, especially at moderate levels, are just one more variable—one that may or may not add to overall variability, depending on the system and timing.
Power system engineers use a whole suite of tools to match supply and demand, both minute-to-minute and over longer time frames. The most obvious example is a dispatchable power plant, like a gas turbine. But they also benefit from bigger balancing areas (trading power with neighbors), more transmission connections to reduce congestion, faster-acting fossil power plants, direct load control and demand response, targeted energy efficiency, and curtailment of wind and solar plants.
Hydro power and even fossil fuels are the traditional forms of energy storage, but many more are emerging, such as using power to heat district heating systems, compressed air, batteries and flywheels, and charging electric cars during the renewable peak.
It is increasingly common to treat wind power as a controllable generator, rather than just letting it go full out. System operators in New York, Texas and the Midwest direct wind farm owners to submit five-minute forecasts of output, and ramp up and down if necessary to meet system demands, just like conventional generators. The Midwest ISO enforces this with a “dispatchable intermittent tariff.”
Making it work: Easy Solutions First
So how can Denmark be 122 percent wind-powered? Where does the extra power go?
Denmark is part of an integrated regional grid with the Scandinavian countries and parts of Germany. They have a constant trade with utilities in the region, especially hydro plants in Norway.
As renewables grow and as Denmark attempts to phase out fossil fuels altogether by 2050, the country is aggressively adopting smart grid technologies, leading Europe in research and demonstration projects on a per-capita basis. The island of Bornholm will be a test bed, with extensive smart grid and renewable energy deployment. Demand response is beginning to grow, though in a different form than in the U.S. Denmark also has big goals for electric cars, and has exempted them from the 180 percent sales tax applied to gas and diesel vehicles.
But conventional solutions will be the first solution through better grid links between countries. As Germany’s Agora Energiewende has put it in its 12 Insights report, “Grids are cheaper than storage facilities.” More grid connections allow surplus power to be shipped off rather than curtailed or stored. Larger balancing areas reduce the variability of wind and solar across a wider geographic area. Agora thinks storage will only be necessary when renewables constitute 70 percent of total supply.
As in the U.S., European regulators are grappling with policies to integrate large amounts of renewables. While technical issues remain, they are not really new, only of a larger scale. Most of the integration tools are known; they just need to be bigger and more capable to deal with bigger variations.
Less known are the policy issues. How big should control areas be? How much should be invested in transmission lines, and who should pay for them? What is the relative value of energy payments, versus capacity payments or ancillary services? Most of all, how should we pay for the services we need to keep the lights on?
In America’s Power Plan, Mike Hogan of the Regulatory Assistance Project calls for aligning power markets with clean energy goals, giving proper incentives for market flexibility.
With 2020 just around the corner, it will be instructive to see how Denmark deals with getting half its electricity from the wind. What will the country do with a 200 percent wind day? ;) ;D

Wind Energy Helps Ward Off Power Outages
Michael Goggin, AWEA
January 08, 2014 | 6 Comments
Over the last 48 hours, wind energy played a critical role in keeping homeowners warm as grid operators across the Eastern and Central U.S. worked overtime to keep up with record-breaking winter demand.
Most importantly, wind energy provided massive quantities of extremely valuable electricity when grid operators needed it most to meet demand from electric heaters and furnace fans. In several cases, wind energy’s output provided the critical difference that allowed grid operators to keep supply and demand in balance and the lights on. Wind energy also helped by offsetting natural gas consumption at gas-fired power plants, keeping natural gas prices in check by making more natural gas available for building heat.
The last two days serve as a powerful reminder that wind energy plays a critical role in diversifying our energy mix, improving energy reliability and reducing energy costs for homes and businesses. Diversity inherently makes the power system more reliable by protecting against the unexpected failures that afflict all energy sources from time to time.
While wind energy output does change with the wind speed, such changes occur far more slowly than the unexpected outages that frequently occur at large conventional power plants. Moreover, changes in wind energy output are predictable using weather forecasting, while conventional power plant failures are not, making them far more difficult and costly for grid operators to accommodate.
Diversifying our energy mix with wind energy also protects consumers from energy price fluctuations. By providing consumers with more choice, wind energy reduces the price of both electricity and fossil fuels and hedges against price volatility, both during times of crisis and over the longer-term.
As the winter storm moved from west to east over the last two days, wind energy repeatedly proved its reliability and value:
As the cold and high winds first rolled into the Upper Midwest, the MISO grid operator saw very high wind energy output of around 8,000 MW, enough to supply 6 million average homes under typical conditions.
Then in Texas, the more than 2,000 MW of wind output on Monday morning was the critical difference keeping heaters running as the grid operator struggled with numerous outages at conventional power plants. More than 13,000 MW of conventional power plants were down for maintenance, while another 2,000 MW of conventional power plants experienced unplanned outages, forcing the grid operator to resort to emergency procedures. In a similar incident two years ago, wind energy earned accolades from the grid operator for helping to keep the lights on as dozens of conventional power plants failed in another cold snap.
More cold air reached the East Coast Monday evening. The grid operator for the Mid-Atlantic and Great Lakes states, PJM, saw very high wind energy output when it needed it most. Wind output was above 3,000 MW when the grid operator faced extreme challenges due to the unexpected failure of numerous fossil-fired power plants as well as two large nuclear power plants in Pennsylvania and Illinois.
Finally, on Tuesday afternoon, very high electricity prices and natural gas prices across New England are being reduced by high wind output across the region’s wind plants.
Wind energy diversifies our energy mix, providing consumers with more reliable and lower cost electricity during both extreme weather and normal conditions.
Agelbert Comment on the comments: ;D
January 9, 2014
Thank you Brian Ross and Jeff Green for providing truth and logical discourse to the comments.
When the tsunami hit the East coast of Japan, wind turbines directly in its path did not fail and continued to provide electricity vitally needed after the disaster. They were the unsung heroes of that tsunami. But not ONE SINGLE newspaper article was written in the USA about these marvels of renewable energy technology.
Also, anyone with absolutely any knowledge about how transmission lines are affected by high winds and loads from freezing rain and/or branches falling on them knows that wind, particularly in the winter, is a huge challenge to grid stability. Centralized power plants WEAKEN the grid by reducing redundancy along the transmission lines that DON'T fail. Multiple redundant power sources like wind turbines are providing a high amount of power exactly when the wind is highest and transmission lines are most subject to outage by wind damage.
Wind turbines are further proof that distributed renewable energy is the only viable future for energy on this planet has. But, of course, the defenders of centralized power utilities will continue to fight it with hyperbole, exaggerations and mendacity while they are silent as tombs about the massive subsidies all these dirty energy providers are sucking out of us in order to remain "competitive". LOL!
I live in Vermont and Green Mountain Power is extremely pleased with wind turbine performance during the recent high winds and freezing rain providing power to thousands of homes with space heaters, not furnaces, for heat.
Yes, New Englanders mostly heat with furnaces but those furnaces require electricity to maintain the combustion spark AND a yearly inspection running over $150 along with skyrocketing heating oil costs. People are pretty tired of that game.
I switched to electric heat and have saved thousands of dollars in heating costs in the last 8 years. For those that use wood pellet stoves, no outside electricity is needed but those still pollute the air MORE than wind turbine electricity heat. We do not need to keep destroying forests to heat our homes! If you can make the pellets from biofuels then go for it as long as you don't contribute to destroying old growth forests; that's just wrong because it hampers biosphere diversity and a livable biome for thousands of species.
Here's my latest blog right here at Renewable Energy World picturing a viable energy future:

This mesmerizing Earth Wind Map showcases real-time data on global wind conditions in the form of snaking neon lines. Breezes are represented by thin strands of green lines, strong winds with long streaks of yellow, while the most violent currents are shown in red.
The Earth Wind Map gathers weather data from the Global Forecast System at the National Center for Environmental Prediction, a NOAA initiative. The script then translates the data into a user friendly interactive animation.
Interactive maps seem to be one of the best ways of bringing environmental data to the general public – in the past we’ve also featured Google’s high-res global deforestation map, and a map showing major U.S. fires in the last 11 years. This fascinating new tool goes above and beyond by providing specific data on the position, date and conditions of wind measurements. The map is not exactly real-time, but it comes pretty close: the data is updated every three hours and it can be set to show wind conditions on any day in recent history.
Some news about WIND POWER that Gail Tverberg may have missed... ;)
This is certainly an interesting initiative, and I’m happy we had the chance to dig into it in more detail than we did when the initiative was unveiled in November.
It does help bring electricity to people without electricity or who are using dirty, expensive, health-damaging fossil fuels for electricity generation — 50 million such people is the target.
It also provides revenue to Vestas and other initiative partners. In other words, it helps the environment, it helps individuals financially, it helps individuals to improve their quality of life a great deal, and it brings revenue to Vestas. Win-win-win-win.
CHEAP renewable energy for up to 1.3 BILLION people by taking old turbines being replaced by new, bigger turbines in Europe, refurbishing them and them putting them in proven high wind areas in third world areas in cooperation with governments providing incentives GIVES INVESTORS over 50% LOW RISK RETURN ON INVESTMENT! As the speaker says, "You don't get any better than THAT for a business venture. (http://www.pic4ever.com/images/47b20s0.gif)
So WHY doesn't Gail Tverberg recognize this and support it? Why does she spend time poo pooing wind power? You KNOW why. She is biased for fossil fuels, period. She is urging people to throw away a tremendous opportunity for clean, environmentally friendly profits that actually help third world countries, unlike dirty polluting energy, in order to safeguard fossil fuel corporation interests.

Japan's Fukushima Commits to 100% Renewable Energy
by Rona Fried
Three years after Japan's nuclear meltdown, Fukushima Prefecture announced it will transition to 100% renewable energy by 2040.
The region, which has a population of about two million people, doesn't want to return to nuclear power even as the national government remains committed to getting the reactors back online. A recent survey shows that 53% of Japan's citizens want nuclear power phased out and 23% want it shut down now.
Currently, Fukushima gets 22% of its energy from renewable sources. One of Japan's biggest solar projects could be located there, but residents also want to bring back small farming communities.
Called "Solar Sharing," farmers are growing crops underneath solar panels. They are growing crops like canola - which absorbs radiation - in an effort to decontaminate their farmland and their abandoned livelihoods. Solar panels are designed on a pergola-type structure that lets in enough sun to grow crops below.
They are also planning 1 GW of offshore wind off Fukushima's coast by 2020, where a $226 million floating offshore wind farm project is already in motion.
Nagano, the Japanese prefecture which hosted the Winter Olympics in 1998, has pledged to switch to 100% renewable energy by 2050.
The nuclear disaster has changed the way people think about energy, Tetsunari Iida, director of the Institute for Sustainable Energy Policies in Japan, told Responding to Climate Change (RTCC). On the other hand, community power development offers a sense of "local ownership and participation."
In Germany, 74 regions and municipalities have already reached 100% renewable energy, according to the newly established Global 100% Renewable Energy Campaign.
At the Warsaw Climate Summit last November, delegates were stunned when the Japanese national government rolled back its long-held target of cutting emissions 25% below 1990 levels by 2020. The new target is 3.8% below 2005 levels by 2020.
Japan's Growing Pains
After implementing the world's most generous feed-in tariff two years ago, Japan is now the world's second-largest solar PV market, installing 7 gigawatts in 2013 (the country has 10.5 GW installed in total). Developers turned more to solar than wind or geothermal because it's cheaper and quicker to develop.
The government target for solar is 28 GW by 2020 - and 40% renewable energy by 2030 - and corporations from Softbank to First Solar have been rushing to fulfill it, with 22.4 GW already approved.
But developers are running into a raft of barriers, most notably limits to grid capacity, but also finding available land, waiting lists for components and a shortage of qualified technicians.
For example, Softbank's 180-plus GW solar project - three large projects on the island of Hokkaido - has been put on hold because the utility hasn't decided which projects will be able to connect to the grid.
About a quarter of all solar projects are being built on Hokkaido, Japan's second largest island, because it's one of few areas with relatively large pieces of inexpensive land. But the grid can't handle all those projects. About 20% are being denied access to the grid altogether and 37% have been told they will have limited access, according to survey by the Japan Renewable Energy Foundation.
To deal with that, the government is building the world's largest battery bank in Hokkaido (the northern part of Japan) and another, much smaller, 2 MW bank in Okinawa (the southern part) to stabilize the flow of solar energy. It will invest $33 billion on grid modernization and development over the next 10 years, particularly to spur growth of wind energy.
Meanwhile, Panasonic's work around to the situation is to focus on small rooftop solar. "Rooftops don't require the purchase of land, and there are transmission lines already available nearby. "Rooftops are going to be more popular," Kazuhiro Yoshida, who heads the solar division, told Bloomberg.
Kyocera is supplying solar panels for installations that spread across 80 farms in Japan.

Denmark: 99% Wind on 25th Jan
January 29, 2014
Denmark is not only the birthplace of the modern wind industry and the original FIT policy concept, but also the pioneer of a bold national target to achieve 100% RE by 2050 in the power, heating, and transportation sectors. And they are well on their way. The screenshot shows that the country is well on its way. On 25th Jan, 99% electricity in Denmark came from wind turbines: 4.112 MW wind production and 4.156 MW electricity consumption.
As one can see from this website of current power production (http://energinet.dk/Flash/Forside/UK/index.html), the Danes publish a real-time overview of their power sector broken down into the categories of central power stations, cogeneration (local CHP), and wind turbines. Add those three together and subtract electricity consumption, and you get the net power exchange.
US Senate Committee Votes to Extend Tax Breaks for Wind Farms (http://www.pic4ever.com/images/earthhug.gif)
Stephen Ohlemacher, Associated Press
April 04, 2014 | 2 Comments
WASHINGTON, D.C. -- U.S. wind farms would keep their treasured tax breaks as part of an $85 billion package of temporary tax cuts passed by a key Senate committee Thursday.
Some U.S. firms with foreign income would be winners too after Senate Finance Committee Chairman Ron Wyden, D-Ore., backed off plans to significantly trim the package.
Congress routinely passes the package of more than 50 temporary tax breaks for businesses and individuals, but they were allowed to expire at the start of the year. The Senate Finance Committee voted Thursday to extend all but two of them through 2015.
The bill passed on a voice vote, with support from both Democrats and Republicans.
Congress is expected to pass the tax package by the end of the year, so businesses and individuals can continue to claim the tax breaks when they file their 2014 taxes next year.
Wyden acknowledged that periodically extending temporary tax breaks makes it difficult for businesses and families to plan. He said he hopes to work on a comprehensive overhaul of the tax system, making some of the tax breaks permanent while eliminating others.
"Many of these extenders are well-intentioned and ought to be permanent," Wyden said. "Their stop-and-go nature obviously contributes to the lack of certainty."
But Wyden's inability to scale back the package shows how difficult it can be to cut cherished tax breaks.
"The challenge on taxes is to always try to find the common ground where you can move ahead," Wyden said after the vote.
Wyden's initial draft of the bill would have eliminated a generous tax credit for using wind farms and other renewable energy sources to produce electricity. But the credit was restored, at a cost of $13.3 billion.
Sen. Chuck Grassley, R-Iowa, claimed credit for saving it.
"Renewable energy supports thousands of jobs and generates billions of dollars in investment across the country," Grassley said. "It's good news for the economy and for energy diversity to restore these provisions."
Democratic leaders haven’t scheduled the measure for consideration by the full Senate. In the Republican-led House of Representatives, (http://www.pic4ever.com/images/pirates5B15D_th.gif) lawmakers are focused on making some provisions permanent and repealing others.

After 20 years of tax breaks for wind that have cost a 100 billion dollars we have an industry that is dependent upon the taxpayers as much as any Pentagon contractor. About half the cost of any wind turbine is paid for with federal subsidies. On top of this there are state mandates and various backdoor subsidies to expand the grid at other people's expense rather than the wind farm paying for this like other power generators. At the same time the wind quality at new sites is decreasing that implies we have used up most of the really good sites when considering both wind conditions and transmission costs. (http://www.smileyvault.com/albums/userpics/12962/noway.gif)
This raises questions. Should the taxpayer rather than the ratepayer pay for electricity bills in the U.S. That is what this level of subsidy implies. Should the political establishment make technology choices? It is a fundamental policy shift in the U.S. Historically the role of government has included R&D and subsidies to help commercialize new technologies. That is to address risks considered too large for the private sector to bear. However, today it is a subsidy program so large that it would make American agriculture blink in disbelief. It is state planning that matches the old Soviet Union--with every indication that it is working about as well. This experiment as been done in Germany where it has managed to double electricity costs within a decade and increase carbon dioxide emissions while only producing 24% of the total electricity demand.(http://www.pic4ever.com/images/2rzukw3.gif)

US Wind Energy Output Breaks Records ;D
Michael Goggin, AWEA
April 04, 2014
Wind energy is breaking records across the U.S., thanks to long-needed transmission upgrades that are relieving congestion on the power grid and allowing more clean energy to reach consumers.
Last week, a new record was set on the main Texas grid, the Electric Reliability Council of Texas (ERCOT), reaching over 10,000 MW of wind. This was the most ever for a U.S. power system, the equivalent of powering more than five million average Texas homes. In two previously unreported records, wind energy supplied a record 39.7 percent of total ERCOT electricity demand this past Monday, March 31, and two weeks ago the Southwest Power Pool region just to the north of Texas set a new wind record with 7,202 MW of wind production.

MUNICH and LONDON -- Siemens AG won a 1.5 billion-euro ($2.1 billion) contract for a Dutch offshore wind park that will also give Europe’s largest engineering company its biggest-ever energy service contract.
The order for the Gemini wind park, 85 kilometers (53 miles) offshore from Groningen, Netherlands, comprises 150 wind turbines with a capacity of four megawatts apiece, the Munich-based company said today in an e-mailed statement.
“We have considerably improved our service approach for this wind park,” Markus Tacke, the head of the wind-power division at Siemens, said in a telephone interview. The provision of equipment accounts for about half of the contract’s value, he said.
Siemens has tempered its willingness to bid for big-ticket work since Joe Kaeser became chief executive officer in August. Delays to projects connecting offshore wind farms to the grid have led to charges topping 1.1 billion euros since 2011, prompting Kaeser to promise investors that the company would be more circumspect in future contract tenders.
The company signed a power transmission contract last month with TenneT Holding BV under more lenient conditions, intended to avoid a repeat of such charges, which have also burdened earnings at Zurich-based competitor ABB Ltd.
Siemens is also building a 160 million-pound ($268 million) wind turbine factory in northern England to improve its ability to serve the North Sea offshore wind market. Britain’s 3,689 megawatts of installed offshore wind capacity represent more than half of the 6,930-megawatts global total, according to Bloomberg New Energy Finance. A thousand megawatts is almost as much as a nuclear reactor produces.
Tacke expects Siemens wind power operations as a whole -- including onshore turbines -- to increase revenue by 5 percent to 6 percent annually in the next two to three years. Siemens has set the division, with sales of 5.2 billion euros last year, a profit margin target of 5 percent to 8 percent of revenue. That compares with a 6 percent margin last year, when charges for faulty onshore turbines held back profitability.
Still, offshore wind projects have been canceled as developers better understand the costs of the projects. Utilities have negated as much as 5,760 megawatts of planned capacity since Nov. 26, when RWE AG dropped its 1,200-megawatt Atlantic Array.
German offshore wind costs may fall as much as 39 percent by 2023, the Stiftung Offshore-Windenergie lobby group estimated in August. The cost at that time was 0.13 euros to 0.14 euros per kilowatt-hour.
The service element of the Siemens deal will last 15 years and includes a dedicated ship and helicopter.
“Service is an important element of the offshore wind industry’s commitment to bring costs below 0.10 euros per kilowatt-hour by 2020,” Tacke said.
The Gemini wind park is due to start operations in early 2017. (http://us.cdn2.123rf.com/168nwm/lenm/lenm1201/lenm120100200/12107060-illustration-of-a-smiley-giving-a-thumbs-up.jpg)
“Overall, it will almost triple the Dutch wind energy output that is currently there,” Gemini Chief Executive Officer Matthias Haag told reporters in Amsterdam today.
Investment in the Dutch offshore wind farm, in which Siemens’s financing arm holds a 20 percent stake, will total almost 3 billion euros. Canada’s Northland Power Inc. owns 60 percent of the group, with Dutch offshore engineering specialist Van Oord NV holding 10 percent and Dutch public authorities the remaining shares.
About 70 percent of the project’s funds were provided in the form of secured construction and term-debt financing from 12 banks, three export-credit agencies and the European Investment Bank, according to a statement yesterday from Northland. The debt has been hedged to give an effective interest rate of about 4.75 percent, it said.
The lenders include ABN AMRO Bank NV, BNP Paribas SA, Bank of Tokyo-Mitsubishi UFJ Ltd., Deutsche Bank AG, Export Development Canada, Natixis, Sumitomo Mitsui Banking Corp., Bank of Montreal, Canadian Imperial Bank of Commerce, Bank Nederlandse Gemeenten, Banco Santander SA and CaixaBank SA, Northland said.
The three export credit insurers are Denmark’s Eksport Kredit Fonden, Germany’s Euler Hermes SA and Ducroire-Delcredere SA from Belgium.

Digging Deeper Into The UGE
Earlier this month, UGE launched its latest vertical axis wind turbine – VisionAIR3. Tina Casey’s coverage on Clean Technica sparked some lively discussion about the small wind industry, both in the comments on the article and in a separate article by Mike Barnard.
Barnard and UGE CEO Nick Blitterswyk recently engaged in a point/counterpoint on some of these areas of contention, and I was Cc’d on all of that. We decided that it would be worthwhile to publish this for a broader audience. An edited version of their conversation appears below.
Nick: First off, Mike, thank you for your article and for the opportunity to have this discussion. Your article provided a good analysis of where the technology is at, and you have every right to be skeptical given the industry’s past.
We’ve tried to be very honest over the years, even when it’s been difficult in an industry that has had a lot of unsubstantiated hype. Like any company, we’ve of course tried to draw interest to our products, but always try to stay within the bounds of reality. We appreciate you keeping things in check.
Mike: I’m glad you reached out.
VIsionAIR5 micro wind turbine.
Nick: One thing you mentioned in your article is the rated sound level. To clarify, 38dBA is the number that Intertek certified the VisionAIR5 unit at, which is the lowest that we know of for any wind turbine. Given the logarithmic nature of the measure, this is significantly less than one rated at 42dBA. To make two other points, first, our units’ RPM decreases as the unit size increases, and this does result in a lower sound level (http://www.clker.com/cliparts/c/8/f/8/11949865511933397169thumbs_up_nathan_eady_01.svg.hi.png) , so the UGE-9M measure of 38dBA we note is correct (as is the higher measure for our smaller VisionAIR3 unit). And second, I thought I would draw attention to the fact that in the certification process Intertek could not discern any measurable volume of noise below 8 m/s, something we also found impressive. (http://www.pic4ever.com/images/8.gif)
Mike: On the noise issue, please understand that I have read virtually every acoustics study related to wind turbines, as well as all the health studies, and interact with acousticians such as Dr. Geoff Leventh all globally every week in my efforts around dismissing the noise and health myths related to utility-scale wind turbines. I write on acoustics regularly and am even occasionally asked to peer review studies in the space. (http://www.pic4ever.com/images/34y5mvr.gif)
The difference of noise is certainly there but is a fairly irrelevant differentiation unless the device is positioned right on top of people’s bedrooms. You can certainly highlight it as a marketing differentiator but from an empirical perspective it’s a trivial amount of noise easily mitigated. In industrial settings it’s even less relevant. And highlighting it as a marketing differentiation for VAWTS tends to tick me off because it feeds a certain class of anti-wind hysteria (http://www.freesmileys.org/smileys/smiley-scared002.gif) (http://www.createaforum.com/gallery/renewablerevolution/3-051113192052.png) (http://www.desismileys.com/smileys/desismileys_0293.gif) which impacts utility-scale wind deployments.
Thanks for pointing out the slower revolutions resulting in less noise. I look forward to certified results on that as well.
Nick: Understanding where you come from on the noise issue helps me understand your point; it’s not one we’d want to muddle for sure. Like you said in your article, there is a class of customer to which this point is important, though, and that is primarily who we are targeting when we mention it is quiet. We meant no harm to the industry; our intent was not to state that a typical HAWT is loud, per se.
Mike: People have overly heightened concerns regarding noise. (http://www.pic4ever.com/images/128fs318181.gif) As my assessment of acoustic attenuation pointed out, any sensible siting will mean virtually no difference between the UGE VAWT and an equivalent HAWT. And outside of a tiny niche of acoustically sensitive commercial sites, once again there will be no appreciable noise from either device. I understand that it’s useful marketing, and that the UGE VAWT is quieter, but it’s going from really quiet to really really quiet, or to put it another way from an irrelevant level of noise to an irrelevant level of noise, for the majority of your customers. But this is a place where people are irrational, and noise is a deeply complex space that’s poorly understood and poorly explained. I’d undoubtedly be using it as a differentiator in your shoes as well.
Nick: Thanks for the clarification. On to the naming issue you raised — the “5″ in VisionAIR5 is named with respect to the height (roughly 5 meters). This is in line with what utility-scale wind turbines most commonly use. Within distributed wind, Southwest for years sold the Skystream 3.7, where 3.7 was the diameter in meters of its rotor. By no means are we trying to confuse anyone into thinking it is rated at 5kW.
Mike: There isn’t a standard per se, just some observable patterns and some potential for confusion. Regarding the number 5 and the impression it leaves, I have looked at specs on a lot of wind generation devices and the majority have output as a numerical qualifier on the name, especially in utility-scale wind. It might be different in the small wind category, especially historically, but that’s more the observed reality that I see. Point taken that it’s not intended to imply output, but I trust you see why it could be misconstrued as well.
Nick: Interestingly enough, when we used to use the kW rating it actually caused a lot more confusion, as 1) people just didn’t understand what it meant, and 2) you’d find companies using any range of rated wind speeds to, in essence, cheat the system. When speaking with our customers we stress the kWh output according to the SWCC certification, which we find a much more useful measure for both ourselves and our customers.
Mike: Fair point. I’m working up more material on real innovation in the wind industry. I’m interested in more information on the levelized energy agreement and your focus on developing nations. Can you share more on that?
Nick: We launched our Levelized Energy Agreement Program last August. Similar to the United Wind model you referenced in your article, it involves project financing, though our fund is dedicated to the telecoms industry in developing countries. The problems of course are well known — expensive, variable, and unreliable diesel, without really any good alternative. What we do is look at the operator’s current costs and lock in the same rate for a 10-year contract. We then upgrade the power equipment on the site (including RE), thereby lowering its OPEX and benefiting over the project lifetime. Because we’re making the primary energy source, diesel, the back-up, and adding RE and batteries, it’s clearly a more resilient solution as well, addressing another key concern.
Whole Foods Brooklyn
Mike: The part that appeals to me is the business model innovation of going after developing countries as a market. It will be interesting to see how that plays out as many countries have small wind generation manufacturing shops of their own, with folks reverse engineering the common designs to create adequate, local and usually very cheap offerings. As adequate eggbeater VAWT blades can be made with pretty much aluminum siding and some wire, it will be interesting to see how that plays out.
Nick: Part of how we’ve been able to raise financing for this market is to separate the country risk as much as we can by targeting large telecom operators with a safe parent, often one based outside of the country our project is in. I’m sure you’ve looked at this too, but the economic returns of DRE projects in developing countries is often very strong, so it’s a nut we’ve at least partially ****, for one (sizeable but somewhat niche) market.
Mike: Once again, I continue to like UGE as a business and wish you every success. Given your model of multiple technologies as a system, it’s unclear why you wouldn’t offer a horizontal axis device as a component to people who want more output for less footprint as well as your vertical-axis device but I’m sure that’s a debate you’ve had internally many times. At least right now UGE is differentiated in part by offering the VAWT, but I suggest to you that business model and channel differentiation are now more important to your future than adherence to a singular wind generation technology.
Nick: We understand that the Cp of our vertical axis wind turbines is currently lower than that of leading horizontal axis wind turbines, though we have been making significant progress over our company’s history to increasing the efficiency and very firmly believe we have the most efficient VAWTs available, with further improvements in the works. Like you said in your article, we benefit from aesthetic and noise considerations despite the lower efficiency; we believe there are durability advantages as well, though admit that is still being proven. This is where the industry is at, and we’re happy to be able to lay the facts bare.
You mentioned in your article that we imply someone could or should place a wind turbine on top of a home. If we say this anywhere I apologize, though I don’t believe we do and would be embarrassed if so. The picture you show in the article was from a very temporary exhibition in Spain, circa 2010, that displayed the unit not unlike one would install a wind turbine indoors at a trade show.
Regarding offering a HAWT, we’ve considered it many times, and we actually offer a 10kW unit in limited volumes. We continue to consider making it a mainstay of our product offering, but for two factors. First, we wouldn’t want to design and manufacture one ourselves unless we felt very confident we could clearly differentiate ourselves in that market. Maybe we could, but it would take years and millions of funding, and we don’t think the pay-off would be there. Which leads me to the second point — unfortunately, very few of our customers are asking for it. The way the solar market is going, we are growing very fast on the solar side, but get very little interest for a horizontal axis wind turbine. We wish that wasn’t the case, but unfortunately it is. Most of our customers wouldn’t consider installing a Bergey-like wind turbine (as solid of a product as it is), but quite enjoy using our VAWTs, so we continue to focus on making that technology as strong as possible for those customers, while also investing additional R&D resources on the rest of the DRE solution, including our SeamlessGrid line of power electronics, battery storage, and site optimization software. So while not married to the VAWT technology, we are happy with how our business model is evolving, but remain open to considering other technologies down the road.
Mike: My external response to people not approaching you asking for HAWTs is that right now your brand is fairly tightly tied to the helical VAWTs. It’s in practically every picture published, it’s visually distinctive and the tiniest bit of Googling leads people to the supposed advantages of VAWTs over HAWTs (and to Gipe’s and my material on the two as well). Good marketing, but not necessarily what’s best for all of your customers. I would bet that if you replaced your graphics stock with 50:50 VAWT and HAWT instead of 100% VAWT, you would get a lot more people asking for HAWTs, or about them. After all, your real innovation isn’t the technology, although you are strongly identified with it right now. UGE really is a small renewables solutions firm whose sole wind component happens to be a VAWT. There’s a chicken-vs-egg thing here, and I think you are ignoring a big part of your potential market, but I’m also sure you’ve had these debates a million times.
To your point about building vs OEMing, I get asked fairly often about how to become a manufacturer of small wind turbines, and I invariably answer, “Don’t.” OEM them and build your own distribution and installation firm, or become part of the distribution channel of an existing company. Designing a new small wind turbine in the USA for manufacturing is a route to bankruptcy, not riches. The products are stable, refined and mostly commodotized. It’s the business model that differentiates these days. There are good choices out there. Given your success, I wouldn’t be surprised to see an outright acquisition strategy at some point.
Nick: Completely agree. On issues like noise, selling a HAWT, etc., it’s clear you know the industry extremely well (http://www.createaforum.com/gallery/renewablerevolution/3-141113185047.png) as you touch on many of the same points we have mulled (and continue to) over the years. In terms of what the future may hold, I look forward to discussing further and keeping you updated! Thanks again for the opportunity to discuss.

BEIJING -- China has taken steps to accelerate the development of its offshore wind power industry in a bid to increase the installed capacity beyond its 428.6 MW installed at the end of 2013.
Some industry analysts expressed pessimism concerning the offshore wind power sector in China as the industry has experienced slow progress with only 39 MW in installed capacity added last year, a year-on-year decline of 69 percent. However, the China National Renewable Energy Centre (CNREC) said that a number of new offshore wind farms are scheduled to kick off within this year, including the 100-MW Phase II expansion project of Don ghai Bridge in Shanghai and China Lon gyuan Power Group’ (Lon gyuan) Nanri Island project already under construction in Fujian province. Two projects are also under contruction in Jiangsu province: China General Nuclear Power Group's new offshore project in Rud ong on track to start construction in the second half of this year and Lon gyuan's windmill project in Dafeng.
In early 2014, the National Energy Administration (NEA) issued a Notice on Developing Offshore Wind Power Projects selecting Shanghai as well as Fujian and Zhejiang provinces as the locations for the country’s key pilot construction projects for offshore wind power. The Shanghai government announced in early May new initiatives to boost support for its new and renewable energy sectors, providing subsidies of 0.1 yuan per kWh for onshore wind power projects and 0.2 yuan per kWh for offshore wind farms. However, some industry analysts expressed concerns about the impact of regional subsidies on the nationwide feed-in tariff for offshore wind projects.
The rapid growth of the Chinese offshore wind power sector requires a rational and clear tariff structure, allowing offshore wind farm developers to have realistic expectations of what the return on their offshore wind power investments should be and in turn, boost the development of the whole sector, according to analysts. (http://www.desismileys.com/smileys/desismileys_0293.gif)
The NEA and the pricing department of the National Development and Reform Commission (NDRC) have been in ongoing discussions concerning the tariff rates for offshore wind farms and expect to issue the rates within this year.
An industry expert at NDRC indicated that the combined capacity of approved offshore wind farms in China, including intertidal projects, has exceeded 4,000 MW. The combined capacity of offshore wind projects scheduled to start construction by 2015 will exceed 300 MW, according to data from CNREC.
The U.S. Department of Energy (DOE) said in early May that it will allocate up to $141 million to three pioneering offshore wind demonstration projects over the next four years to help speed up the deployment of more efficient offshore wind power technologies. Benefiting from the support for offshore wind projects in the U.S., Fishermen's Energy's 25MW offshore windmill backed by Xiangtan Electric Manufacturing, a China-based electrical equipment manufacturer, won a US$4 million grant from the DOE, subject to regulatory approvals.

The rapid growth of the Chinese offshore wind power sector requires a rational and clear tariff structure, something the Chinese are serious and methodical about because they are clear eyed about what the future holds if they do not make sure ALL renewable energy technologies achieve the goal, and achieve it SOON, of total demand destruction for fossil fuels. That's what the USA can't seem to understand.
This is NOT about replacing an inferior technology for harvesting energy with a superior and cheaper technology; this is about Homo sapiens survival. The Chinese understand this. If only the USA did. We have, in the USA, the stupidest, most suicidal energy policy on the planet.
I hope the Chinese pull the plug on the building of coal power plants, decommission built ones and embrace Amory Lovins' accurate assessment of industrial civilization that with efficiency increases in the energy production technology from power source to consumer, over 90% of the wasted energy can be eliminated and we can power ALL the needs of present industrial civilization with only 10% of what we now use. It's called NEGAWATTS and it is REAL. Why? Because a 5 to 10% efficiency increase (easily achievable with modern technology) in the transmission and/or generation of power has a multiplicative effect when it reaches the consumer. A 5% efficiency increase at the generation source EQUALS over 70% energy saving at the consumer. That is why the consumer savings, so far, have had such a small effect on fossil fuel demand. That HAS to change. Amory Lovins knows how to do that and has been doing it for several years.
I think China gets it. Our US (s)elected (by the fossil fuel oligarchy) "representatives" don't. >:(
Offshore wind power to grow six-fold, boosting turbine makers, HSBC says (http://elqahera-trading.com/home/wp-content/uploads/2012/04/dollar-sign-thumbnail1.jpg) (http://elqahera-trading.com/home/wp-content/uploads/2012/04/dollar-sign-thumbnail1.jpg) (http://elqahera-trading.com/home/wp-content/uploads/2012/04/dollar-sign-thumbnail1.jpg) (http://elqahera-trading.com/home/wp-content/uploads/2012/04/dollar-sign-thumbnail1.jpg) (http://elqahera-trading.com/home/wp-content/uploads/2012/04/dollar-sign-thumbnail1.jpg) (http://elqahera-trading.com/home/wp-content/uploads/2012/04/dollar-sign-thumbnail1.jpg) :o ;D
Offshore wind power is set to grow six-fold by 2020, benefiting turbine makers including Vestas Wind Systems (VWDRY, VWSYF) and Gamesa Tecnologica (GCTAF), HSBC says.
Total global installed capacity of wind turbines at sea is forecast to rise to 43 gw by 2020 from 6.5 gw at the end of 2013, with the U.K., China and Germany the biggest offshore wind markets, according to HSBC.
The opportunity for manufacturers justifies a strategic long-term focus on the offshore segment, the firm advises; after 2015, “the rapid growth in offshore installations becomes a key to driving growth in wind technology."

The nautilus shell took time off from fitness-namesake duty to inspire The Liam F1 Urban Wind Turbine, which we are renaming The Not-So-Little Turbine That Could. Dutch firm The Archimedes designed the swirl-shaped windmill to be way quieter and more efficient than others (plus, it’s blue!). The firm says the turbine can generate 80 percent of the maximum possible energy yield, a big jump from the typical 25 to 50 percent. Hot damn.
PSFK thinks it’ll be great for your apartment, but at five feet wide, it might not exactly fit on your Brooklyn fire escape. At least the noise won’t wake you up in the middle of the night, which is one of the big drawbacks of most residential wind turbines/randy apartment neighbors.
Here are the Liam’s specs:
The Liam F1 generates an average of 1,500 kilowatt-hours of energy [per year] at a wind-speed of 5 m/s [16.4 ft/s], which resembles half of the power consumption of a common household.
If you feel like spending 8 minutes looking at wind turbines (bonus: set to the Pirates of the Caribbean theme song!), there’s also this:
So get out $5,450 in pennies — the Liam goes on sale July 1! ;)
Agelbert NOTE: Amory Lovins has been talking about this for years in pump technology. Now the wind people are finally getting in it. ;D why is this a big deal? Because it flips Reynolds numbers and turbulent flow and laminar aerodynamics theories on their heads as to efficiency and power output. The Fibonacci pattern of wind vanes completely blows away the competition in wind to power output from other types of wind generators.
This is the kind of doubling and tripling of efficiency type breakthrough that will make mincemeat of dirty fossil fuel internal combustion machine energy. (http://www.pic4ever.com/images/balloons.gif) ;D

Global Wind Energy Day

NEXTera Energy wind farm, pictured (at link) in 2013, has 250 wind turbines that dot the landscape north of Limon. (Helen H. Richardson, The Denver Post)
June 15 is Global Wind Energy Day. As Colorado is a world leader in wind energy production, it is not only fitting to tout our success, but to encourage its further production.
Colorado's installed capacity of 1,530 turbines produces 2,332 megawatts of electricity, or 13.8 percent of the state's electricity, and powers the equivalent of more than 870,000 average Colorado homes. But according to the American Wind Energy Association, the state has the 13th best wind resource in the nation, and this wind power has the potential of meeting more than 24 times the state's current electricity needs.
With 19 manufacturing facilities, Colorado's wind industry provides employment for about 5,000 workers. ;D This is set to increase when NextEra Energy Resources completes its wind farm 28 miles east of Colorado Springs. That facility is scheduled to come on line by late 2015.
What's holding Colorado back from developing this renewable energy resource to its full potential? At least two things: the untruth that only renewables are subsidized; and that damages incurred to the natural environment in energy production are borne by society — not the energy producers and its consumers.
The Production Tax Credit for wind farms expired at the end of 2013, and Colorado Sens. Mark Udall and Michael Bennet are asking for a 10-year extension of the program. A bill that would have provided about $13 billion for wind energy stalled in the Senate on May 15, amid cries of "corporate welfare" from its opponents.
Nick Loris with the conservative Heritage Foundation told the Washington Free Beacon that "taxpayers shouldn't be footing the bill to help it [wind energy] remain economically viable." He said the subsidy is equal to "shifting labor and capital around to 'politically preferred sectors of the economy.' "
However, the Free Beacon avoided anymention of the $4 billion in annual tax breaks — otherwise known as subsidies — to the fossil fuel industry. Nor did it include reports on the cumulative dollar amounts, over the lifetimes of their respective subsidies, at about $630 billion in the U.S. for oil, coal, gas and nuclear industries, while the renewable energy sector (wind, solar and biofuels) received roughly $70 billion.
In other words, let's end that $4 billion in annual subsidies for the fossil fuel sector. After all, if the sector's viable, it can stand alone.
However, Bloomberg New Energy Finance reports that even without the subsidy, the cost of wind energy has declined by 42 percent over the past four years as technology has improved. ;D
Our society doesn't put a price on our water supplies or our clean air. Nuclear and fossil fuel producers pollute and consume these resources to nonsustainable levels, and then these damages are externalized and borne by society at large.
Thermoelectric power plants fueled by coal, natural gas, oil and nuclear fission all boil water to produce steam, which then turns a turbine that generates the electricity. This water comes from our streams, lakes and rivers, with the power plants also drawing in and killing millions of fish per year. After the water passes through the turbine, more water is needed to cool the steam back into water for reuse. Nationwide, electricity production is the largest user of water.
Coloradans deserve an honest discussion of the state's wind power potential as well as its benefits to society and to our natural environment. Let's not be hijacked by those with vested interests in the fossil fuel industry.

Distributed Wind Energy: The New Cash Crop(http://elqahera-trading.com/home/wp-content/uploads/2012/04/dollar-sign-thumbnail1.jpg)
Russell Tencer, CEO, United Wind
July 02, 2014
With so many day-to-day concerns vying for attention, many farmers may not have the time to stop and research alternative ways to address their energy needs and rising utility costs. While having heard that renewable energies, such as solar or wind energy, are becoming increasingly popular, there does not seem to be a way for them to reap the benefits without a significant amount of capital available. However, due to advancements in technology and market availability due to new leasing models, distributed generation is changing the way farmers gain access to and manage their cost of power.
While many people are familiar with distributed solar energy (such as installing solar panels on your rooftop), distributed wind is becoming a new option for property owners. Unlike a traditional utility-scale wind farm, distributed wind is the use of smaller, on-site wind turbines for a home or business owner’s personal power supply. Established wind companies are now bringing distributed wind to the masses by providing a turbine leasing solution to farmers looking to benefit from predictable and affordable energy.
So how exactly can farmers take advantage of this new “cash crop?”
The Answer is Blowing in the Wind (http://www.4smileys.com/smileys/seasons-smileys/storm.gif)
Innovations in wind turbine technology have helped fuel growth in the industry for many years. According to the American Wind Energy Association (AWEA), the average price of U.S. wind power has declined by 43 percent since 2009. As a result, distributed wind is just beginning to take off as a viable alternative for farmers, small businesses, and residents in more rural areas. This recent uptick is due in large part to new leasing models becoming available to businesses and property owners — negating the historical need for the sizeable capital investment that comes with owning a turbine.
Distributed wind companies are beginning to serve this previously overlooked customer base by offering farmers and agricultural businesses stability and predictability when it comes to their utility bills. With the knowledge that their utility bills will be predictable every month, farmers now have a hedge against inflation and the flexibility to direct more money back into their business, spurring organic growth rather than just keeping the lights on.
Historically, if farmers were interested in switching to wind energy, an initial capital investment of tens of thousands of dollars was needed for the outright purchase of a turbine. With new long-term leasing options now available and eliminating those high upfront costs, distributed wind is becoming a realistic alternative energy option for farmers nationwide.
Prior Concerns Are Disappearing into Thin Air ;D
Along with guaranteeing predictable energy production, distributed wind companies are taking the hassle out of wind project development, including taking care of the paperwork and permitting process, which has been a deterrent for potential owners up until this point. Farmers can now keep focused on day-to-day operational matters with the comfort of knowing that their energy supplier is handling these tedious and time-consuming processes.
Distributed wind providers are also working with local contractors and government entities to ensure the installation of turbines runs smoothly and efficiently, with minimal disruption to a farm’s operations. Some wind companies are even offering ongoing maintenance services to monitor performance and safety of the wind turbines, and customers are guaranteed these services throughout a 20-year lease period.
United Wind's leasing process begins with an evaluation in which the customer shares a brief history of their utility bill in order to realize how much they will save by going with distributed wind. The customer then receives a custom WindQuote which includes a full wind analysis and personalized leasing options. Lastly, the installation process begins.
As for pricing, customers are able to score a $0 down lease in New York State due to strong incentives from NYSERDA. A few other states also fall into this category, as well. The customer can opt to prepay a portion or the entirety of their lease for even greater savings over time. We find that even with the $0 down option, many clients have opted to prepay in order to reap these additional benefits.
Assuming the customer did not full prepay their lease, a monthly lease payment can vary greatly, but generally runs between $100-$1,000 depending on turbine selection, amount prepaid (if any), and their wind resource. Fully prepaying a lease would be a fraction of the cost of an outright purchase of a machine. Not to mention that a fully prepaid lease can come with a 20-year production guarantee, warranty, maintenance, and insurance.
In order to stand behind the machines with a production guarantee, warranty, insurance, and maintenance for 20 years, we work with only the best products in the industry, for example Bergey Wind Power's Excel 10-kW turbine and Endurance Wind Power's E-3120 50-kW turbine. Similarly, the company chooses to work with only the top local installers in the areas where the turbines are being erected, such as CEC (Casenovia Equipment Company) Energy and SED (Sustainable Energy Developments).
In addition to changes in financing options, technology has evolved over the last few years to address and dispel former logistical concerns, namely:
•Access to wind: Wind is an unlimited resource. While we all have access to it, research has found that an average wind speed of just 10 MPH provides a great starting point for wind energy collection.
•Access to land: While land is not always readily available, it does not take a lot to accommodate smaller wind turbines, with a general recommendation of three acres or more for proper siting, installation, and unobstructed wind flow.
Bottom line, distributed wind energy is becoming more accessible, more desirable, and more financially viable than ever before, particularly for the agricultural market. With barriers to adoption blowing away, ;D this efficient and cost effective means of powering our nation’s farms has a bright future.(http://www.desismileys.com/smileys/desismileys_0293.gif)

US installs 835MW in 1H 2014 (http://www.createaforum.com/gallery/renewablerevolution/3-200714183515.bmp)
5 August 2014 by David Weston , Be the first to comment
UNITED STATES: Figures from the AWEA reveal the US installed a capacity of 835MW in the first half of 2014, compared to just 1.6MW in the same period of 2013.
Last year's low figure was as a result of uncertainty in the sector due to the delayed extension of the production tax credit (PTC).
Texas saw the greatest increase in capacity, with 400MW installed followed by Nebraska (201MW) and Michigan (136MW).
The southern US state was helped by the 218.3MW Panhandle 1 project being commissioned in the second quarter.
According to AWEA, the US now has an installed capacity of 61.9GW from 46,300 turbines.
Texas is set to continue leading the way with capacity, as over 8GW in projects are currently under construction in the state. In total, the US has 14.6GW of wind under construction across 106 projects in 21 states. (http://www.smile-day.net/wp-content/uploads/2011/12/Smiley-Thumbs-Up2.jpg)

New Cable Technology Can Carry Twice as Much Power from Offshore Wind Farms ;D
Patrick Winters, Bloomberg
August 21, 2014
ABB Ltd. said a power-cable technology that allows offshore wind farms to transmit more than twice the energy of current set-ups will boost orders at the company’s power systems division in coming years.
“It’s on the list of ABB’s most important breakthroughs in the last five years,” Chief Technology Officer Claes Rytoft said in an interview, adding that rival technologies are at least some years behind. “We know about projects that have not moved forward because they are missing this.”
The technology will spur the construction of even bigger offshore wind farms by doubling the power capacity of cable connections to about 2,600 megawatts from 1,000 megawatts today, making it the most powerful subsea connection system in the world, Rytoft said. It includes high-voltage power cables, joints and terminations.

Excellent! Ocean currents are THE greatest source of untapped 24/7 base load quality Renewable Energy there is. AND those currents (that will never stop as long as the earth continues to rotate) are close to over 90% of the major concentrations of human population known as COASTAL CITIES.
Within a 130 km of every major coastal city in the world is enough undersea current to power them many times over, at base load quality 24/7, immune to ocean surface storms, and with very low transmission losses due to the short distance from the harvesting point to the user.

Water, Energy and Waste Sustainable Development in Large Cities
There is no doubt that humans in general, and those concentrated in cities in particular, are responsible for much of the massive demand for potable of water and energy. There is also agreement that this demand is, at present not healthy for the biosphere in general and humans in particular. There is too much waste, inefficient energy use, lack of renewable energy infrastructure, pollution from fossil fuels and inefficient water use as well.
In summary, there is a consensus among knowledgeable and observant people in the reality based community that our present trajectory in the above issues is unsustainable.
The solution requires the phasing out of all fossil fuels and nuclear fission power plants and replace them with Renewable energy. This energy needs to be harvested within 100 miles or less from the highest energy users on the planet, the large cities, in order to have lower transmission and infrastructure costs.
The energy must be baseload quality 24 hours a day with wind and solar to supplement demand spikes along with pumped water storage energy, fuel cell or battery storage technologies.
The renewable energy source that is best suited on a global scale because it is constant, powerful and close to the major cities is the energy from ocean currents.
Observe the two maps below.
World population concentration
Now look at the one below where I merged the two.
The energy is renewable, does not disturb the biosphere or hydrosphere and can completely replace the polluting energy we now suffer from. The densely populated areas have this powerful source nearby.
Ocean currents have far more energy potential than ocean tides. The tides alone are estimated to have a potential tidal stream energy capacity of over 120GW globally. Using both plus wind and PV would make a 100% Renewable Energy transition to the 18TW the planet required feasible with technology we now have.
Just in the UK alone, the marine power resource is estimated to be more than 10GW, representing about 50% of Europe’s tidal energy capacity.
In the USA a project is now in the works to provide wind turbine power to the East Coast for up to 1.9 million households. When built out, the Atlantic Wind Connection (AWC) backbone will stretch 350 miles off the coast from New Jersey to Virginia and will be able to connect 6,000MW of offshore wind turbines.
Now look at where those wind turbines will be and realize that undersea turbines can be placed close by and save on cabling the energy to the shore. Much more energy can be harvested 24 hours a day from the ocean current. Sharing energy transmission cables from wind and ocean current turbines will save millions of dollars and hasten the transition to 100% clean energy.
As the new, clean energy replaces dirty energy, full electrification of the economies to eliminate the internal combustion engine for power plants, vehicles and factories will clean the air in large cities.
With plenty of renewable energy to electrify the planet and eliminate the internal combustion engine pollution, the worldwide potable water problem can be solved anywhere on the planet that the relative humidity is above 23% (any place it is not a desert climate) by extracting water from the ambient air.
The waste water can, given all the ocean current energy, be processed for agricultural fertilizer (eliminating petrochemical fertilizers).
In this way, we will imitate the biosphere in turning our waste into a nutrient that benefits all life on earth, not just humans.

Wind Technologies Market Report
After modest growth in 2013, total installed wind power capacity in the United States now stands at 61 gigawatts (GW), which meets nearly 4.5 percent of electricity demand in an average year, according to the 2013 Wind Technologies Market Report, released today by the Energy Department and its Lawrence Berkeley National Laboratory. The report also found that wind energy prices – particularly in the Interior region of the United States–are at an all-time low, with utilities selecting wind as a cost-saving option. (http://www.createaforum.com/gallery/renewablerevolution/3-200714183515.bmp)
With utility-scale turbines installed in more than 39 states and territories, the success of the U.S. wind industry has had a ripple effect on the American economy, spurring more than $500 million in exports and supporting jobs related to development, siting, manufacturing, transportation and other industries.
How to Build a Wind Turbine From Scratch ;D
Thanks to filmmaker Jake Beed and the Action4Climate video competition, you can have a first-hand look at what it’s like to build a wind turbine from scratch. In If You Build It, watch a group of young Canadians strive for a more sustainable way of life by figuring out how to generate their own power via a homemade wind turbine.
With little to no prior knowledge or experience, the group finds help in the surrounding community’s skill sets that all come together to create a moment that will last for as long as the wind blows. This film is inspiring. It shows how you can build a community by building a wind turbine and that passion is the key ingredient to getting things done.
Renewable energy deployment is key to solving global energy issues. Especially in energy poor countries, it’s vital that communities embrace clean energy and work on strategies to keep the power generation locally owned.
One great example is in the Dharnai village in Bihar, one of India’s poorest states. The community is now lit-up by a community-owned solar-powered micro-grid. Dharnai is the first village in India where all aspects of life are powered by solar. The 100 kilowatt (kW) system powers the 450 homes of the 2,400 residents, 50 commercial operations, two schools, a training center and a health care facility. A battery backup ensures power around the clock.
“If we are to end extreme poverty, we must tackle energy poverty,” said World Bank Senior Director for Energy & Extractives Anita Marangoly George. “With 1.2 billion people still living without electricity across Sub-Saharan Africa and South Asia, it’s clear where our work will be focused for the foreseeable future. Our priority is to find the cleanest energy solutions to meet local needs in the smartest ways possible.”

Wind energy is blowing away skeptics — it's so close to achieving cost parity with fossil fuels that just a little extra efficiency is all that is likely needed to push it into the mainstream and past the Energy Department's goal of 20 percent wind energy by 2030.

That extra efficiency may be realized with the help of a software tool built by the Energy Department's National Renewable Energy Laboratory (NREL). It's called Simulator for Wind Farm Applications (SOWFA), and it can calculate how undulating ground, whipping blades, surface temperatures, and other variables alter the air flow and energy production at wind farms.

This Wind Turbine Is Bringing Clean Energy to New Heights
October 29, 2014
Written by Lorraine Chow
Wind turbines are found on land and sea, but now there’s a new type on the horizon that can tap energy thousands of feet in the air.
As the video below explains, the helium-filled Buoyant Airborne Turbine (BAT) is capable of producing twice the amount of energy of an ordinary turbine because it feeds off the stronger, faster and more consistent winds of higher altitudes. Cables tethered to the machine then send the generated wind energy back to a base station.
Created by MIT startup Altaeros Energies, the tube-shaped BAT can be inflated, set up within a day and transported anywhere by a truck, which significantly reduces the installation costs of a typical tower-mounted wind turbines. This is in sharp contrast to other land-based turbines, which require giant support platforms and lots of material, and offshore ones that need a platform strong enough to withstand punishing ocean waves, which is tremendously expensive to anchor to the seafloor.
Another potential of the BAT is that it can cheaply and efficiently power remote and off-grid communities (as well as areas struck by disaster). As Popular Science reports, one such off-grid locale has already been piqued by this new technology.
Thanks to a $740,000 grant from the Alaska Energy Authority, Altaeros will be testing out the first commercial BAT near the city of Fairbanks starting next year. The 30-kilowatt system is poised to provide power and even WiFi to a dozen families living off the power grid. If the 18-month trial is a success, it could reduce the area’s diesel consumption by 11,000 gallons annually.
It’s a bird! It’s a plane! It’s a wind turbine! (http://www.freesmileys.org/emoticons/emoticon-object-081.gif)
Agelbert NOTE: This technology is aerostat technology. The technology of mounting heavy machinery on them is is over 30 years old. It has been used for at least that long to mount radar to catch drug smugglers and other unauthorized flights. It is robust. The savings on siting and mast infrastructure is HUGE.
During storm conditions they can be brought near the ground where they will be more safely tethered while still getting plenty of wind power during the storm. This is another giant nail in fossil fuel and nuclear power DIRTY energy's coffin! GOOD! ;D

Making the Blade Photoessay: How and Where Wind Turbines Get Their Swoosh
Joan Sullivan, Contributor
October 28, 2014
An industrial wind turbine is a complex machine made up of hundreds of moving parts, but it takes just three of them to make the magic possible: the blades.
Wind turbine blades harvest energy from currents of air, but they don’t come off an assembly line like widgets. Indeed, it’s difficult to appreciate just how much effort and care goes into crafting them until you see the process up close.
That’s why I was recently honoured to be the first professional photographer to lens the shop floor at PowerBlades Industries in Welland, Ontario. The company is a Canadian subsidiary of German wind turbine manufacturer Senvion.
PowerBlades opened last year to support the growth in renewable energy in Ontario spurred in turn by the province’s Green Energy Act. As of this week, the company will have fabricated 78 fiberglass blades, each 45 meters long and up to three meters wide, for dozens of 2.05-MW Senvion turbines.
Birth of a Blade
Inside PowerBlades, overhead cranes move girders and blades from one part of the building to the next. Here, 136 production workers, machine operators, and office staff work on various stages of blade production, including lay-up, lamination, curing, sanding, painting, inspection, repair, finishing, loading, and transport.
Blades begin their lives in the plant’s Main Shell Area, where workers lay sheets of fiberglass mat and resin into a pair of side-by-side proprietary molds each about 50 meters long and four meters wide. Each blade is built up in two halves, split down the long axis like a pea pod.
Full size pictures at link to 25 page photo essay
Once the resin cures, workers carefully glue the two halves together. Eight to 10 workers then physically climb into the blade to scrape out excess glue from the inside. They then apply heat to finish the curing and gluing process.
Going Over the Wall
Crane operators then gingerly lift the blade to the first of several finishing stations in a delicate process known as “going over the wall.” Over the course of several weeks, operators will lift and shift each blade to a variety of finishing stations for trimming, laminations, adding minor hardware (such as receptors and the pointed tip), sanding, painting, and “root end close out,” which involves installing a plywood attachment that seals off the base of the blade.
Like sculptors, workers swarm over every inch of the blade with palm sanders, painstakingly and meticulously smoothing out bumps and imperfections, before the cranes again hoist the blades to the painting section.
Buckets and Rollers
The final phase of finishing is refreshingly low-tech — four painters, two on each side, attack each blade with rollers. Each takes two coats of paint, about 15-20 gallons in total. On average, it takes a couple of days for the team to finish its work.
Gantry operators then lift the finished blades one final time into shipping crates and convey them out of the building into the storage yard. From there, Senvion’s clients truck them to installation sites.
The crew at PowerBlades take great pride in their work, knowing that they are not only making a good living, but also slowly-but-surely reducing their province’s dependence on natural gas and nuclear energy.
“We’re so proud to be working here,” explained Adam Chevalier, a 28-year-old production worker. “To have a job, first. And then to have a job that is doing something good for the environment, renewable energy, it’s great!” (http://www.pic4ever.com/images/128fs318181.gif)

Scotland Produced Enough Wind Energy To Power Every Home In October ;D
According to new numbers published by WWF Scotland this week, wind turbines generated enough electricity in October to power 3,045,000 homes in the U.K. :o (http://us.cdn2.123rf.com/168nwm/lenm/lenm1201/lenm120100200/12107060-illustration-of-a-smiley-giving-a-thumbs-up.jpg) — more than enough for all the homes in Scotland.
Referring to it as a “bumper month” for renewable energy, WWF Scotland’s director Lang Banks said in a statement that “while nuclear power plants were being forced to shut because of cracks, Scotland’s wind and sunshine were quietly and cleanly helping to keep the lights on in homes across the country.”
Based on figures provided by WeatherEnergy, part of the European EnergizAIR project, the data also showed that for those homes fitted with solar panels, there was enough sunshine to meet around 40 percent of the electricity needs of an average home. (http://us.123rf.com/400wm/400/400/yayayoy/yayayoy1106/yayayoy110600019/9735563-smiling-sun-showing-thumb-up.jpg)
(http://www.4smileys.com/smileys/seasons-smileys/storm.gif) ;D Wind energy has been thriving in the U.K. in recent months. In August the U.K set a new record for wind power generation, with wind accounting for seventeen percent of national demand. This came around the time that EDF Energy announced it was temporarily shutting down four of its U.K. reactors, or around a quarter of its total nuclear generating capacity, due to longevity issues. The four EDF reactors under investigation were commissioned in 1983 and are officially scheduled to be taken out of service in 2019. (http://www.pic4ever.com/images/47b20s0.gif)
Even for the U.K., Scotland is a green energy leader. As of September, the country got 29.8 percent of its electricity from renewables, 34.4 percent from nuclear, and only 34.4 percent from fossil fuels. Scotland hopes to generate the equivalent of 100 percent of its electricity from renewables by 2020 and to export non-renewable production (http://www.freesmileys.org/emoticons/emoticon-object-070.gif) from conventional power plants to countries like England.
In the first quarter of this year, Scotland generated a record 6,678 gigawatt-hours of renewable electricity, according to government figures, an increase of 55.9 percent from a year before. Wind generation in the first quarter of 2014 was also at a record high level of 4,214 GWh, up 4 percent year over year.
According to the government, as of March of this year Scotland had 6.8 gigawatts of installed renewable electricity generation capacity, with an additional 6.5 gigawatts of capacity either under construction or consented, the majority of which is expected to come from onshore wind generation. Including projects in the planning stages, this figure totals 20.5 gigawatts.
Scotland’s largest wind farm is also the U.K.’s largest. Whitelee Windfarm near Glasgow has a 539 megawatt capacity, and generates enough electricity to power just under 300,000 homes.

Energy Storage Will Soon Replace Simple Cycle Combustion Turbine Peaker Plants 8)
Chet Lyons, Principal, Energy Strategies Group
November 05, 2014
Power grids need extra generating capacity to work properly. For example, about 20 percent of New York State’s generation fleet runs less than 250 hours a year. :o Because they don’t run much, “peaker plants” are by design the cheapest and least efficient fossil generators. When they do run they cost a lot to operate and produce more air pollution than other types of fossil generation. Wouldn’t it be great if we had a cost-effective and environmentally sustainable substitute for dirty fossil-based peakers? (http://www.pic4ever.com/images/128fs318181.gif) (http://www.createaforum.com/gallery/renewablerevolution/3-051113192052.png)
As has happened with solar PV, the costs for multi-hour energy storage are about to undergo a steep decline over the next 2 to 3 years. This cost trend will disrupt the economic rationale for gas-fired simple cycle combustion turbines (CTs) in favor of flexible zero emissions energy storage. This will be especially true for storage assets owned and operated by vertical utilities and distributed near utility substations.
Simple cycle gas-fired CTs have been a workhorse utility asset for adding new peaker capacity for decades. But times and technologies change, and the power grid’s long love affair with gas-fired CTs is about to be challenged by multi-hour energy storage. Flow batteries that utilize a liquid electrolyte are especially cost-effective because the energy they store can be easily and inexpensively increased just by adding more electrolyte.
CTs cost from $670 per installed kilowatt to more than twice that much for CT’s located in urban areas. But the economics of peaking capacity must also reflect the benefits side of the cost/benefit equation. Distributed storage assets can deliver both regional (transmission) and local (distribution) level energy balancing services using the same storage asset. This means the locational value and capacity use factor for distributed storage can be significantly higher compared to CTs operated on a central station basis.
These points are discussed in Energy Strategies Group’s white paper, “Guide to Procurement of Flexible Peaking Capacity: Energy Storage of Combustion Turbines.” As noted in the paper, Capex for a 4-hour storage peaker is projected to be $1,390 by 2017, or $348 per (installed) kilowatt-hour of capacity. Factoring in the added value of locating storage on the distribution grid and ownership and operation by a vertical utility, 4-hour energy storage will win over CTs at the high end of the CT cost range by 2017. (http://elqahera-trading.com/home/wp-content/uploads/2012/04/dollar-sign-thumbnail1.jpg)
By 2018 the cost of ViZn Energy’s 4-hour storage solution, which was selected by Energy Strategies Group as a proxy for the lowest cost multi-hour storage solutions currently being commercialized, is projected to be $974 per kW, nearly identical to that of a conventional simple cycle peaker. For a 4-hour storage resource – that translates to $244 per (installed) kilowatt-hour of capacity. Given the added benefits of installing storage in the distribution network, by 2018 storage will be a winner against the mid-range cost for a simple cycle CT and clearly disruptive compared to higher cost simple cycle CTs.
The disruptive potential of energy storage as a substitute for simple cycle CTs has been recognized. For example, Arizona Public Service (APS) and the Residential Utility Consumer Office (RUCO) recently filed a proposed settlement which, if approved, would require that at least 10% of any new peaker capacity now being planned as simple cycle combustion turbines would instead need to be energy storage — as long as the storage meets the cost effectiveness and reliability criteria of any CTs being proposed.
When selecting new peaking capacity, utility planners can choose between assets that better fit the emerging distributed grid architecture or the older and disappearing centralized approach to grid design. The choices we make today should be consistent with current and long-term cost-performance trends in fossil-based generation, solar PV and energy storage.
Lower cost solar PV and its rising penetration in all market segments will have a profoundly disruptive effect on utility operations and the utility cost-of-service business model. This has already started to happen. Storage offers a way for utilities to replace lost revenues premised on margins from kilowatt-hour energy sales by placing energy storage into the rate based and earning low-risk regulated returns

UK Approves 750-Megawatt Offshore Wind Project (http://www.pic4ever.com/images/balloons.gif)
Alex Morales, Bloomberg
November 07, 2014
LONDON -- The U.K. approved construction of one of the biggest offshore wind farms as the country chases a European Union target to get 15 percent of all energy from renewables by 2020.
The consent allows Dong Energy A/S to install up to 750 megawatts of turbines at the Walney Extension project in the Irish Sea off northwest England’s Cumbria, the Planning Inspectorate said today in an e-mailed statement. Denmark’s Dong said it expects to put in about 660 megawatts of turbines, enough to power as many as a half-million homes.
“This decision to grant development consent now clears the way for the company to make a final investment decision on the project,” Benj Sykes, vice president of U.K. wind for Dong, said in an e-mailed statement.
The U.K. already has more than half of the world’s installed offshore wind-generating capacity, and is pushing the technology to help meet its renewable energy targets.
Dong expects to use 6- to 8-megawatt turbines, it said. The utility owns 50.1 percent of the project, SSE Plc owns 25.1 percent and a joint venture between Dutch pension administrator PGGM and Ampere Equity Fund own the remainder. The project was awarded guaranteed power contracts by the government in April.
It’s the second approval in less than two months for a U.K. project by Dong, the biggest offshore wind developer. Its 250- megawatt Burbo Bank Extension project in Liverpool Bay was granted approval on Sept. 26. That’s next to an existing 90- megawatt farm, and the Walney extension is adjacent to the existing 367-megawatts of Walney 1 and 2 wind farms.
The U.K. currently has 22 operational offshore wind farms totaling 3,653 megawatts of capacity, according to the RenewableUK lobby group. The biggest is the 630-megawatt London Array, a collaboration between four companies, including Dong and EON SE. While no bigger project is currently under construction, today’s approval is the fifth of 750 megawatts or greater to receive consent, according to the data.

Texas Wind Powers 3.3 Million Homes
Anastasia Pantsios | November 17, 2014 1:36 pm | Comments
When you think of “energy” and “Texas,” you probably think “oil.” But those wide-open spaces sitting on those lucrative oil fields also make it a prime location for another form of energy generation: wind. (http://www.4smileys.com/smileys/seasons-smileys/storm.gif) (http://elqahera-trading.com/home/wp-content/uploads/2012/04/dollar-sign-thumbnail1.jpg) (http://www.pic4ever.com/images/Banane21.gif)
The Roscoe Wind Farm in Texas has an operational capacity of 781 megawatts. The wind farm started operations in 2009 and has 627 turbines installed.
Texas’ own top power source by far is gas (50 percent), followed by coal (32 percent) and nuclear (9 percent). But it is also the nation’s leading producer of wind energy—and growing. While the state is home to the 3rd and 5th dirtiest power plants in the U.S., it also produces nearly a quarter of the country’s total wind power. It has created the second largest number of green jobs after California. Currently, wind is the power source for 3.3 million Texas homes, driven by private investment, a deregulated and competitive electricity market, federal incentives and Texas’ own clean energy goals to reach 10 GW of renewable energy generation by 2025, according to research done by the Pew Charitable Trusts, released at a webinar today.
“Pew’s research demonstrates that a reliable electricity grid requires both a diversified mix of affordable generation sources such as wind and government policy to foster deployment,” said Jeff Clark, executive director of the Wind Coalition. “Texas consumers are benefiting because the state has capitalized on the federal production tax credit to build its wind industry, which provides more than 177,000 jobs.”
Sunny Texas is also rapidly increasing its solar energy capacity. It ranked 8th in new installed capacity last year, providing more than 4,000 jobs statewide. Progressive cities like Austin and San Antonio took the lead with their own aggressive renewable energy goals that encourage such new projects and investment.
“Texas illustrates how state and federal policy can complement one another to spur deployment of clean energy and attract private investment,” said Tom Swanson, manager of Pew’s clean energy initiative. “The outcomes include job creation across the state, energy and cost savings for businesses, and reliable, affordable energy for residential customers.”
According to the Pew report, Texas is also the leader in industrial energy efficiency technologies which produced heat and power from a single source or capture wasted heat to generate electricity. “These technologies can help manufacturers reduce energy consumption, costs, and water use—all of which are critical in Texas given the state’s high electricity prices and chronic droughts,” said the Pew report.

“Texas has emerged as a clean energy leader, with its unparalleled wind and solar resources and a large manufacturing industry ideal for exploiting industrial energy efficiency,” Pew asserted. “With further policy support, the state can continue to tap into this potential and use it for economic growth.”
But further policy support is the big question mark. While Texas surpassed its renewable energy goal for 2025 in 2010, there are signs of possible retrenchment. :P
According to an interactive tool released last week by Earthworks, “A bill is pending that would eliminate the renewable portfolio standard and strip the Public Utilities Commission of its authority to regulate trading of renewable energy credits.” That’s part of a coordinated nationwide push by heavily fossil fuel-funded groups like the Heartland Institute, Americans for Prosperity and the American Legislative Exchange Council (ALEC). Similar legislation has been introduced in about two dozen states with only one scalp so far: Ohio froze its clean energy standards in July and its legislature is currently considering repealing them entirely.

Finally, US Gets An Offshore Wind Farm, Deepwater Starts Construction Next Spring
After too many years of delays to count, the US is finally about to get our first offshore wind farm. (http://www.freesmileys.org/emoticons/tuzki-bunnys/tuzki-bunny-emoticon-052.gif)
Deepwater Wind will start construction this spring now that it's received final state and federal permits. Don't get too excited - it's just five turbines near Block Island, considered part of Rhode Island.
To give you an idea of what these permits are: one is a submerged lands lease with Rhode Island. Deepwater will pay $150,000 a year for the right to anchor its turbines to the ocean floor. The other permit is federal - giving Deepwater the right of way for the transmission cable that carries the electricity to the grid on land.
The area is prime habitat for migrating right whales, which are extremely endangered, and Deepwater - in concert with environmental groups - came up with a way to make sure they are protected:
•a traffic-light system of red (no construction allowed in early spring) yellow and green is based on when whales are likely to be in the area.
•ships will be slowed to 10-knots from Nov. 1 through May 15 to prevent collisions
•noise-reduction and attenuation technologies developed in Europe will be used
•better surveillance measures will spot right whales - expert ship-based observers; restricted work at night and when visibility is low; and aerial surveillance.
In August, the Department of Interior held its third auction for offshore wind leases, this time offering 80,000 acres off the coast of Maryland, an area which could power 300,000 homes (850-1450 megawatts).
It took 19 rounds of bidding for US Wind (subsidiary of Italy's Renexia) to win the entire lease for $8.7 million against two competitors, Green Sail Energy and SCS Maryland Energy.
Notably, the winning bid is much higher than the first two auctions, where winners bid just $1.6 million near Virginia and $3.8 million off the coast of Massachusetts.
The competition was more intense and resulted in much higher bids because Governor O'Malley got the first legislation passed in the US that subsidizes offshore wind. It offers developers up to $1.7 billion for a 200 megawatt (MW) project and higher prices for electricity once it starts producing.
Here's how ocean leasing works:
The winner has a year to submit a Site Assessment Plan for approval, which describes how it will measure wind resources in the lease area. If that's approved by BOEM, the lease has 4.5 years to submit a Construction and Operations Plan, which details the wind project. BOEM then conduct an environmental review of the project, which includes public input, and if it's approved, the lessee gets a term of 25 years.
Including this latest Maryland auction, 357,000 acres in the Atlantic Ocean have been leased for about $14 million. Last week, New Jersey regulators rejected Fishermen's tiny 5 MW wind project for the second time.
Leases awarded to date:
•Cape Wind - Massachusetts
•Deepwater Wind - Rhode Island/ Mass.
•NRG Bluewater Wind - Delaware
•Dominion Virginia Power - Virginia
On January 29, 742,000 acres off the Massachusetts coast will be auctioned in the largest lease sale to date.
New UK Projects
Danish utility Dong Energy has been cleared to build a 700 MW offshore wind farm off the coast of England, to start operations in 2023. One of the countries biggest, it will power 500,000 homes.
This year, five offshore projects have been approved in the UK, which together will produce 4% of the country's electricity - powering 3 million homes - while creating 8500 jobs. The UK has 22 operational offshore projects with a capacity of 3.7 gigawatts, according to RenewableUK.

Innovative Wind Turbine Designs From Australia
In the past five years, bigger, more advanced wind turbines have greatly improved performance and lowered the price of wind energy, but that's nothing compared to what scientists in Australia are working on.
A team at the University of Wollongong is in the final stages of developing offshore wind turbines that are 1000 times more efficient at one-third of today's price. (http://www.pic4ever.com/images/za4.gif) They hope to see the turbines installed along Australia's wind-blown coast within the next five years.
The key seems to be the use of superconductors and elimination of the gear box. While gearless turbines have been around for years, replacing it with a superconducting coil captures wind and converts it to electricity without any power loss.
"In our design there is no gear box, which right away reduces the size and weight by 40%," explains lead researcher Shahriar Hossain. "We are developing a magnesium diboride superconducting coil to replace the gear box. This will capture the wind energy and convert it into electricity without any power loss, and will reduce manufacturing and maintenance costs by two thirds."
That cuts the cost of turbines to $3-5 million each, down from $15 million today ;D, and they would be much easier to transport without the heavy gear box, they say.
Researchers are making superconducting coil from magnesium and boron, which is inexpensive, durable and easy to make. Since the materials don't generate electrical resistance, they can store electricity without losing any energy, and they can circulate the current indefinitely.
"With industry support, we could install superconducting offshore wind turbines off the coast of Australia in five years, no problem," says Hossain.
Power WINDows ;D
Another innovative wind design from the same university is Power WINDows, invented by Professor Farzad Safaei (http://www.pic4ever.com/images/19.gif). You can see it placed between two city buildings:

"My primary aim was to overcome some of the key shortcomings of current wind turbine technology, in particular, enable modular manufacturing, transportation and installation, reduce noise, land usage footprint, and better integration with living environments."
To do that, he developed a modular design that looks like a large window and can be deployed in metropolitan areas as well as wind farms. Panels inside the window rotate slowly with the wind, replacing spinning blades. This quiets the turbine and creates less turbulence around it, greatly decreasing its overall footprint. It also makes it cheaper and easier to manufacture, install and operate. Need more energy? Just add more panels. ;D

Energy Innovation Doesn't Just Happen: How Government Policies Destroyed and Regenerated the U.S. Wind Turbine Industry, Twice
Posted December 8, 2014
By Nathaniel Horner (http://www.pic4ever.com/images/19.gif)and Inês Azevedo (http://www.pic4ever.com/images/19.gif)
After a decade of annual near-death experiences, the production tax credit (PTC)—a tax benefit for generating electricity from certain renewable sources like wind—was allowed to expire at the end of last year. Like other policies such as investment tax credits and renewable portfolio standards (RPSs), the PTC was designed primarily to help shift the country’s energy supply towards more renewable sources. The response to these policies has largely come from wind generation, which now contributes over 4% of U.S. electricity supply. A different set of policies in various European countries has enabled wind to meet over 7% of E.U. demand.
There are generally two ways to increase electricity generation from wind: we can construct more wind plants, or we can make the wind plants we build more productive. Arguments for the PTC tend to focus on the former: counting new project starts and added capacity, and noting ancillary benefits like jobs and economic stimulus. This makes sense, since it’s easy to count wind turbines cropping up over the landscape, and the relationship between the presence of incentives and the pace of construction can be readily seen.
The second means of increasing production is through technology innovation, and, in contrast to construction projects, it can be difficult to measure—innovations are not as easily countable as turbine towers, and the response time between implementation of an innovation policy and the appearance of any resulting technological advances in the commercial market is not immediate. Furthermore, when considering incentives for innovation, policymakers face difficulties of determining the counterfactual, i.e., would the advance occur even without the incentive? Nonetheless, innovation has been an immensely important part of the wind electricity success story: turbines today are larger and have higher capacity factors than their predecessors, reducing the cost of wind electricity to levels more or less competitive with conventional generation. If advances in technology had not happened, then wind projects would likely always need subsidies to be economically viable. Thus, it’s worth looking beyond building wind plants to think about how government policies incentivize technology innovation as well.
Innovation policy design
There are two general theories of innovation policy. Under technology-push policies, governments aim to reduce the costs of investing in innovation by providing direct subsidies—most often, R&D funds. Under demand-pull mechanisms, policymakers hope to increase the payoffs of investing in innovation by enhancing the market for the technology. The PTC and RPSs fall under this category—they create a demand for wind capacity, thereby (perhaps) inducing wind turbine suppliers to invest in creating better technology. Within each of these categories, policies can either be market interventions, like the PTC, that give one technology preferred treatment in the market, or command-and-control regulations, like the RPSs, in which a certain standard must be met. We often think of these respective options colloquially as carrots and sticks.
Command-and-control policies can be particularly effective at promoting innovation when they are stringent enough to be technology-forcing, that is, when meeting them is difficult using current technology. Notable examples of technology-forcing regulations in the U.S. occurred with emissions control technologies for power plants and automobiles.
Incentivizing the wind
So which policies, if any, have been successful in the U.S. at not only incentivizing construction, but also inducing innovation? The history of wind technology development in the United States provides a clear example of how important the policy environment can be for innovation.
Many of us think of serious wind development in the U.S. beginning in the 1970s, but the first wind buildup actually occurred in the early half of the twentieth century. Enterprising rural farmers connected parts from water-pumping windmills, generators, and batteries to provide household electricity, and by the 1930s mass-produced “windchargers” could be purchased (via the Sears catalog, among other outlets). Hundreds of thousands of these small turbines soon dotted the American Midwest, but the establishment of the Rural Electrification Administration in 1935 and its subsequent aggressive push to connect these isolated farms to the electric grid essentially killed this industry by the 1950s.
The promise of atomic energy and cheap fossil fuels in the post-WWII era meant little interest in wind. By the latter half of the 1970s, however, stubbornly high nuclear plant costs and the oil embargo sowed the seeds for the first wind renaissance. The U.S. government took two significant policy actions to encourage wind technology. First, the Large Wind Turbine (LWT) R&D program administered by DOE and NASA attempted to develop commercial, utility-scale (multi-megawatt) wind turbines (Figure 1). Second, the government issued what amounted to a 25% investment tax credit on wind turbine construction. Combined with state-level policies, the tax credit in California totaled 50%, and the wind rush was on. Instead of investing in large, complex machines, the order of the day was to build small and build fast. By 1985, 13,000 150-250 kW plants were constructed (Figure 2).

Were these policies successful? The LWT program failed to produce a turbine that made it to commercial production. The large plants proved technically complex and generally unreliable, and while some prototypes met with limited success, many met the fate of the Boeing MOD 2 turbine at Medicine Bow, Wyoming, which was dynamited and sold as scrap for $13,000 just five years after being built at a cost of $6 million.
In California, the tax credit incentivized construction of the turbines, but there was no incentive for those to then produce electricity. As a result, many plants were unreliable: the worst wind farms had capacity factors of less than 10%, and a not insignificant portion were later removed. The most successful turbines were of an older, simple, Danish design.

By some accounts, these two policies were high-profile failures that set the industry back a decade as people became disillusioned with wind. To be fair, though, these programs at least established a foothold for wind generation in the U.S. A DOE report found that the R&D program laid the technological foundation for later growth, while in California, the state retained enough working turbines in 1990 to produce over 2.5 TWh of electricity annually.
A second wind renaissance began just before the turn of the millennium. Coincident with the PTC (enacted in 1992) and state-level RPS policies—which mandate a certain proportion of electricity generation come from renewable sources—established beginning in the late 90s, the U.S. has seen dramatic growth in wind production over the past fifteen years.
We have mentioned four main policies involved in the history of U.S. wind generation: the level of federal R&D spending, the investment tax credits of the 1980s, the PTC, and the state-level RPSs—one technology-push policy and three demand-pull policies. It seems reasonable to conclude that the investment tax credits were not “technology-forcing,” and thus unlikely to have spurred innovation. But how do we assess policy effectiveness? First, we need to a way to measure innovation.
Economists use patent counts as one possible proxy for innovation, for reasons mainly related to data availability. Notwithstanding the well-documented limitations of this metric, it is not an unreasonable way to get a rough idea of the relative level of innovation activity within a particular technology area over time.
You can see a chart of patent counts juxtaposed with these policy variables in Figure 3 and can probably make a few reasonable hypotheses about the relationship between each policy and patenting activity. If we can also represent these policy variables (and additional “control” factors) quantitatively, we can set up a regression equation to determine which policies are most correlated with innovation. This is exactly what we do in a recent paper, to which we refer you for all the modeling details.
Wind patenting and policies
Figure 3: Wind patenting rate over time (blue) juxtaposed with various wind policies: level of federal wind turbine R&D funding (top, green); counts of state-level renewable portfolio standards (bottom; red); and periods during which various tax credits were in place (bottom, shaded). Image from our paper (Horner et al 2013 Environ. Res. Lett. 8 044032).
Our results support the conclusion that the investment tax credits had no effect on innovation. Federal R&D had a significant, but small correlation, supporting the idea that these investments have been marginally effective. Perhaps the most interesting finding is that the state-level RPS policies, and not the PTC, are most correlated with patenting activity.
These results make sense for several reasons. First, of these policies, the RPS is the only command-and-control mechanism and is thus most likely to be technology-forcing. Wind farm operators desire to meet renewable generation mandates as efficiently as possible. Some of the costs of building and operating a wind farm, such as land acquisition and tower construction, would be expected to scale on a per-turbine basis. Larger turbines also utilize better quality wind at a higher altitude. Therefore, larger turbines likely achieve lower per-MWh costs. The experience of the federal R&D program indicated the need for technological advances to achieve reliability in these larger sizes, and thus there was an incentive to invest in innovation.
Second, the lack of an effect from the PTC in spurring innovation may have had a lot to do with how the credit was implemented. Beginning in 2000, the credit was renewed for periods of only one or two years and was allowed to expire briefly three times. Because there is a lag between innovation investment and delivery to the market, this short renewal period did not inspire confidence in suppliers that a payoff for investment would still exist in the future. RPSs, in contrast, provided a stable, long-term signal that there would be a market for better turbine technology.
The history of wind turbine technology is quite fascinating, and there’s much more that can be said about how policies have affected its development. However, we’d like to end with two takeaways. First, transformative innovations often need government support to transition from the high-risk early period to a state where industry can take over. The fact that wind turbine technology has needed policy intervention to achieve its current level of success should not be seen as an indictment of it. After all, the IT and aerospace industries are full of technologies now providing huge societal benefit but that needed government support early on.
Second, the manner of this support—policy design—is critically important. Successful policies balance between rolling out existing technology and incentivizing investment in the next generation of technologies. The investment tax credits of the 1980s were mis-targeted, and a careful survey of the technology landscape could perhaps have provided a more fruitful direction for the LWT program. One important policy attribute is time horizon: when dealing with innovative technology areas, often a longer-term view is warranted. The lack of predictability in the PTC renewal schedule likely hindered its effectiveness in inducing innovation (though it clearly led to turbine construction), and an expiration date further in the future would perhaps have made it a more effective driver of technological progress.
Policy decisions arguably killed wind in the U.S. in the 1930s and 1980s, and policy decisions brought it back both times. While it doesn’t look like wind is headed for a third death in the near future, the talk of rolling back RPS policies in some states does threaten to bring the same sort of instability that plagued the PTC. In any case, the lessons learned from the history of wind policy should be useful as we look to incentivize development of other energy technologies.
 For an excellent history of U.S. wind energy through the early 1990s, see Robert Righter’s Wind Energy in America: A History (University of Oklahoma Press, 1996).
 Only one multi-megawatt turbine had ever been built—forty years previous! The 1.25 MW Smith-Putnam turbine successfully fed electricity into Vermont’s electricity grid in 1941, but suffered two equipment failures, and interest faded in the postwar environment.

 Admittedly, this is a simplistic characterization of how RPSs are deployed in practice. RPSs vary drastically from state-to-state; many allow for at least some of the mandate to be fulfilled via purchase of renewable energy credits and have cost-effectiveness requirements. These attributes can make RPSs less stringent than typical command-and-control policies, and thus less effective technology-forcers. For a detailed look at how each state’s RPS is set up, see dsireusa.org.

Transforming the Grid with Clean Energy — Reliably — Every Day ;D
John Moore, Senior Attorney, The Sustainable FERC Project
December 19, 2014
Despite years of successful experience, dozens of studies, and increasing utility support for clean energy, urban myth holds that electricity from renewable energy is unreliable. Yet over 75,000 megawatts (MW) of wind and solar power have been integrated, reliably, into the nation’s electric grid to date. That’s enough electricity to supply 17.9 million homes.
And, as a new NRDC fact sheet published today illustrates, the electric grid can handle much higher levels of zero-carbon wind and solar power, far more than what’s necessary to achieve the relatively modest carbon emission reductions in the U.S. Environmental Protection Agency’s plan to limit pollution from existing power plants. But first, a little background on how our nation’s electric system works.
The nation’s high-power transmission system is made up of three largely separate grids: one on either side of the Continental Divide (roughly) and the third in Texas. The two largest grids are further subdivided into regions managed by different regional and local utility grid operators.
Source: MJ Bradley & Associates using Ventyx Velocity
Grid operators are the air traffic controllers of the power system, managing the flow of electrons from power plants to customers across thousands of miles of transmission lines. They operate the grid under extremely detailed procedures and standards.
Planning for the Next 5 Minutes and the Next 10 Years
To ensure a reliable transmission system, grid operators think in several time frames. In the immediate seconds to hours, they run the grid according to a detailed set of economic and electrical engineering rules embedded in sophisticated computer programs. These programs dispatch power plants with the lowest operating costs first, subject to important constraints to preserve the grid’s stability and avoid blackouts.
Grid operators also plan years into the future to ensure reliability. In the same way that one would not set out to drive across the desert on a half-tank of gas, they want to ensure enough power exists and can be delivered to meet consumer demand years ahead. To do so, they identify factors that could either increase or decrease the need for more power and power lines, and then plan accordingly.
Wind and Solar Power Hit the Big Leagues
There is more renewable energy flowing through the power grid than ever before. At times, wind has supplied more than 60 percent of the total demand on some utility systems, without reliability problems. And solar power now routinely contributes 10 to 15 percent of midday electricity demand in California, which has more solar panel installations than anywhere in the country.
Source: American Wind Energy Association independent analysis based on real time data publicly available by ISOs and utilities
Accurate Forecasts and Advanced Technologies Matter
Due to more precise weather forecasts and sophisticated technologies, grid operators increasingly can predict--and control--wind and solar generation levels. Accurate predictions of wind speed and solar conditions help grid operators efficiently schedule renewable energy into the system. Using advanced and often-automatic control systems, grid operators can both increase and decrease the power output into the grid, which helps to stabilize the grid’s electrical frequency and maintain reliability.
Wind and Solar Need Less Backup Power than Coal, Gas and Nuclear
Every power plant on the grid needs “backup” power in case something happens to prevent it from generating as much electricity as planned. PJM, in charge of most of the grid from New Jersey to Illinois, currently holds 3,350 MW of expensive, fast-acting contingency reserves 24/7 to ensure that it can keep the lights on in case a large fossil or nuclear power plant unexpectedly breaks down. In contrast, MISO – the grid operator for the middle part of the country with the most wind power in the nation – needs almost no additional fast-acting power reserves to back up its 10,000-plus MW of wind power on the system.
Why is so little backup power needed for wind and solar? In contrast to the large, abrupt, and often unpredictable changes in electricity output from coal and nuclear power plants, wind output changes tend to be gradual and predictable, especially when wind turbines are spread over larger areas. The fact that a wind farm is a collection of many smaller turbines also helps, since the failure of one has little impact on the farm’s total output.
Our Grid Is Successfully Integrating Clean Energy Now and Will Continue
The power grid has always adapted to changing state and national energy trends and needs, thanks to regular operations and planning frameworks. Forty years ago grid operators learned to accommodate the sudden losses of generation that can come from integrating very large nuclear power plants into the system.
Now, as utility-scale wind and solar power rapidly expand, grid operators are successfully integrating these new resources into the grid while retiring many outdated, costly, and polluting coal plants. And they’re doing it without most Americans even noticing. Maybe that’s the best proof that wind and solar power are not just ready for the big leagues, they’re already there.

The Project: Manzana Wind Power Project Creates Renewable Energy and Local Jobs
Project profile of the Manzana Wind Farm
Renewable Energy World Editors
December 24, 2014
In the wind-rich Tehachapi area near the town of Rosamond, California the 189-MW Manazana Wind Power Project, developed by Iberdrola Renewbles, generates electricity and sells it to San Diego Gas and Electric under a 20-year PPA. The project came online in 2012 and boasts 126 GE turbines.
At the height of construction, when these photos were taken, the wind farm created 290 construction jobs. Minnesota-based Blattner Energy managed construction, with the majority of the work sub-contracted to local California companies. Today, there are twelve permanent Iberdrola Renewables operations and maintenance staff who run the facility and eight or nine additional contractors work for the facility while it is still under warranty.

The above video is from the Department of Energy (DOE). It is WAY too conservative in its projections of wind power growth.
In fact, they admit that their 2008 study projection, prepared by 100's of scientists from 70 plus organizations (like the one NOW they are about to publish), of 48 GW of wind power by 2013 was A BIT OFF. ;D
By 2013 the USA had 61 GW of installed wind power. The REALITY was 127% of the projection! That's why the Koch brothers and friends have gone nuts trying to kill "big wind". That's why recently, not one, not two, but THREE stalking horses for fossil fuel foot dragging have wormed their way into the DOE.
The video talks about all the REAL cost savings from increasing percentages of wind power in our grid. The FACT that wind power saves HUGE amounts of WATER is mentioned as well.
What it fails to mention is that we DO NOT NEED to wait until 2050 to get a lousy 35% or so. We CAN get that by 2020! That is why the friends of dirty energy in Congress want to kill any benefit, no matter how small, compared with dirty energy subsidies, to slow down the wind renewable energy juggernaut.
The WAR is RAGING! (http://www.websmileys.com/sm/violent/sterb029.gif) Watch the video. Keep in mind that the DOE has an "all the above" policy DICTATED by our fossil fuel government. But at least they are not lying about the Social Costs of dirty energy pollutants. They are REAL costs and we-the-people are sick and tired of paying them. >:(
Report finds Iowa’s wind jobs come out on top ;D
Photo from AWEA's Flickr, all rights reserved
A new report on advanced energy employment in Iowa shows that the wind industry employs an impressive 3,600-plus workers in the Hawkeye State.
The report by the Advanced Energy Economic Institute found that wind energy “dominates” among jobs supported by advanced electricity generation industries in Iowa,, with 68 percent of workers in that segment working in wind. The report is consistent with research by the American Wind Energy Association.
The state numbers are impressive, but what may be most telling in the report is its meaning beyond Iowa’s borders. The report, for instance, notes the correlation between jobs and a commitment to renewable energy. Iowa has a long history of providing a conducive policy environment for tapping its renewable resources. In the 1980s, Iowa became the first state to institute a renewable portfolio standard.
“It’s easy to see why Iowa has a sizable workforce,” the report notes. “The state is a national wind energy powerhouse, as these [2013 American Wind Energy Association] statistics demonstrate: first in the nation in the percentage of electricity generated by wind (27 percent), third in megawatts installed, and third in the number of utility scale wind turbines.”
The report also notes how the growth of wind power has contributed to Iowa economic development beyond the industry itself, citing as examples the decisions by both Google and Facebook to locate data centers in the state—in part because of the availability of clean, affordable wind energy.
Another takeaway that’s applicable elsewhere: Those states most familiar with wind energy seem to like it the most. From the Iowa report: “Iowans overwhelmingly support the growth of the wind energy segment. Fully 85 percent of people in the state view wind energy more favorably than any other energy source, providing political support for pro-wind policies.”
However, the report also found that wind energy employment in the state has declined compared to 2013. The report states that “[t]his decline occurred during a sharp downturn in the U.S. wind industry associated with the expiration, followed by renewal, of the federal production tax credit (PTC), which resulted in the 90 percent drop in wind industry revenue in 2013.” :evil4:
To avert more of the all-to-familiar boom-bust cycle, Congress must implement long-term policies to promote wind -- states like Iowa depend on it. (http://www.emofaces.com/png/200/emoticons/fingerscrossed.png)
Agelbert NOTE in regard to the relation between our survival and the autotrophic biomass health: Already, Negative effects on MIDDLE TROPHIC levels of climate change are being documented.
Climate change enhances the negative effects of predation risk on an intermediate consumer.
We found that both predation risk and increased air and sea temperatures suppressed the foraging of prey in the middle trophic level, suggesting that warming may further enhance the top-down control of predators on communities. Prey growth efficiency, which measures the efficiency of energy transfer between trophic levels, became negative when prey were subjected to predation risk and warming.
The proof that the autotrophs (phototrophic - algae, phytoplankton, grass, trees - photosynthetic life forms and the prokaryotes, the cyanobacteria, the lithotrophs and the methanogens) are affected by higher temperatures to the point of endangering Homo SAP survival has already been documented.
I will provide more info on the growing awareness of the scientific community about our UNSUSTAINABLE path BECAUSE of the danger to autotrophs as well as the middle trophic levels.
Autotrophs, being the primary producers, are always at the bottom of the food chain. They are responsible for converting CO2 to a form required by the heterotrophs.
They have not been able to make FIRM conclusions because of the complexity of life form interactions but they are getting there. (http://www.pic4ever.com/images/reading.gif)
Research has already found that due to global warming, bacteria and fungi reproduce more rapidly (Agren, 2013). At the same time, they even use a larger share of the available carbon for their own respiration, bringing more CO2 into the atmosphere which stimulates atmospheric warming even more (Agren, 2013). This is how micro-organisms are believed to contribute to global climate change. Both in the carbon and nitrogen cycles there are certain levels of complex metabolic activities which are influenced by inorganic nutrients (Six et al ., 2006).
These activities are quite vigorous and fluent but will tend to alter if there is change within the surrounding environment. This may result in vehement effects and impacts on global climatic phenomena leading to change in its natural occurrences. (http://www.createaforum.com/gallery/renewablerevolution/3-310714182509.png)
Save the autotrophic biomass from climate change so your ass won't be grass. Demand 100% transition to Renewable energy PLUS (for sequestering of carbon and bioremediation of planet polluting poisons) NOW!
Excellent info on wind turbines for the home. (http://www.clker.com/cliparts/c/6/7/1/12065737551968208283energie_positive_Wind_Turbine_Green.svg.hi.png)
Many golden tidbits of essential information including wiring efficiency differences between AC and DC, why AC turbines are a better deal with a rectifier located where your juice does the work or goes into a battery bank, why odd numbered blade turbines are better (http://www.pic4ever.com/images/128fs318181.gif), a good discussion of blade materials, angles and designs and also a discussion of turbine towers. (http://www.runemasterstudios.com/graemlins/images/2thumbs.gif)
The sun will weaken PVC blades and high speed winds will DESTROY them. :P Do NOT buy PVC blades.
In fact, ANY plastic is TOAST under daily sunlight after a while. I suppose fiberglass would work but they would be much heavier than metal ones. Heavier blades mean higher wind speeds to get them moving. So, if you are in a low wind area, fiberglass is out too. 8).
I learned a lot from this video. The discussion of the charge controller, inverter and how EXACTLY they are connected was great. Also, the "dump load" feature to keep a wind turbine from wind milling was particularly enlightening. (http://www.pic4ever.com/images/47b20s0.gif)

It's for producing energy! The Wind Tree is made up of a steel trunk and mini turbines. It's designed to harness energy from even the slightest of breezes, so it's producing energy even on days with very low wind.
From the French start up "New Wind", these silent and powerful windmills should appeal to those who oppose the size and noise of traditional turbines.
They stand 11 meters tall, and are designed to fit into the urban environment.

China Leads World On Wind Additions Again; Offshore Wind Creates Double the Jobs As Drilling
The results are in for wind industry growth in 2014, with the US and China continuing their leadership positions.
Developers in the both countries (and Germany) rushed to get projects in the ground before incentives declined or expired -leading to 4.7 gigawatts (GW) added in the US and an impressive 20.7 GW in China, according to Bloomberg New Energy Finance (BNEF).
In the US, projects had to be started by the end of 2014 - which means a good year ahead (http://www.runemasterstudios.com/graemlins/images/2thumbs.gif) - and in China, the feed-in tariff will soon be cut. :P
Last year, capacity grew 38% in China, where a total of 96 GW of wind is now installed, says BNEF. After leading the world with 16 GW installed in 2013, China's government raised the target to 200 GW by 2020. (http://www.pic4ever.com/images/maniac.gif) ;D
Even though China leads on capacity, the US pumps out more wind energy. (http://www.4smileys.com/smileys/seasons-smileys/storm.gif) (http://www.createaforum.com/gallery/renewablerevolution/3-200714191258.bmp)
The other top countries for wind additions are Germany (3.2 GW), Brazil (2.7 GW) and India (2.3 GW).
The 947 MW Alta Wind Energy Center in California. it is the biggest wind farm in the world so far.
Jobs From Offshore Wind
Just as the US is about to get its first - if tiny - offshore wind farm and Republicans get ready to push for extensive offshore oil drilling in the Atlantic, another report shows the advantages of offshore wind. (http://elqahera-trading.com/home/wp-content/uploads/2012/04/dollar-sign-thumbnail1.jpg)
Offshore wind would create double the jobs and double the energy as offshore drilling in the Atlantic Ocean, reports Oceana, while drilling would actually threaten the 1.4 million jobs in fishing, tourism and recreation. And the threats begin with oil exploration - where seismic airguns blast the ocean floor from Delaware to Florida, harming millions of fish, dolphins and whales.
"Unlike offshore drilling, offshore wind provides power directly to coastal communities where we need energy the most, without the risk of oil spills or carbon pollution," says Andrew Menaquale, author of the report and energy analyst at Oceana. "It's time for the US to use the lessons learned from more than 20 years of offshore wind development internationally and apply them to generating clean, renewable energy off our coasts."
Findings include: (http://www.pic4ever.com/images/reading.gif)
•In 13 years, offshore wind could generate more energy than all economically recoverable offshore oil and gas resources.
•Gradual offshore wind development for the next 20 years, would supply electricity to over 115 million households.
•Extracting all recoverable oil would meet 5 months of demand, and 10 months of gas demand at current consumption rates.
•The Atlantic Ocean contains less than 4% of US oil reserves and less than 3% of gas reserves.
A previous study shows offshore wind could power the entire Atlantic coast, while creating 300,000 jobs, and would also protect the coast from devastating hurricanes. (http://www.pic4ever.com/images/Banane21.gif)

Photoessay: A Day in the Life of a Wind Farm Operator

Have you ever wondered what it takes to run a wind farm? You’ve seen all the amazing photos taken from the tops of turbines, but do you know what the technician is actually doing up there?
A photographer followed around the crew at the Bull Hill Wind farm in Maine. Here’s a glimpse into their daily lives on the job. (http://www.renewableenergyworld.com/rea/news/article/2015/01/photoessay-a-day-in-the-life-of-a-wind-farm-operator?) (http://www.pic4ever.com/images/reading.gif)

Thank you, Christine Duval. I love to see people making a decent living working on behalf of future generations on jobs that will never be outsourced.
I predict that, in the near future, both the ten minute climb and the ten minute descent will be eliminated by a one man electric winch elevator.
These "winches" are old technology used by scaffolding workers that wash skyscraper windows. It is simply a drill that attaches to a fitting on the scaffolding frame and cables (you need two men running a drill on both ends to raise the scaffolding evenly - a tricky process if one drill is running faster than the other - not for the feint of heart).
I'm certain a better version for wind turbines will be developed to enable quicker access. Time is money.
Wind power to create 4,200 Maine jobs this year, boosts state economy (http://www.createaforum.com/gallery/renewablerevolution/3-200714183515.bmp)

— 6 Jan, 2015
A new economic report predicts that the wind energy industry could create as many as 4,200 jobs in the state of Maine alone in 2015.
In addition, the report demonstrates that the industry has already invested nearly $550 million into the Maine economy since 2006 and will invest another $750 million in the next few years.
The analysis of wind energy in Maine released today shows that the industry has made a significant positive impact on the state’s economy, not only in terms of investment, but also in terms of creating jobs. The study states that the industry has been employing more than 1,500 people per year and helping to open new markets for Maine companies.
Conducted by Charles Colgan, Ph.D., and the Maine Center for Business & Economic Research at the University of Maine in conjunction with Wind for Maine and the Maine Renewable Energy Association (MREA), the report’s major findings include:
◾New investment of nearly $1.28 billion between 2006-2018;
◾$1.14 billion in employee earnings over the same period;
◾Creation of 1,560 jobs per year, peaking in 2015 at 4,200; and
◾Development of new markets for 23 Maine-based companies that led to nearly $89.6 million in sales in 2011-2013 and 390 jobs in Maine.
Wind for Maine and MREA announced the results of the report at a press conference today and in a press release.

Wind Intermittency Is a Myth, says AWEA (http://www.pic4ever.com/images/47b20s0.gif)
The Achilles Heal for wind energy is intermittency, or that's what we have been told.
We need coal, nuclear and gas for reliable, baseload power, is the common refrain, but that's a myth, according to the American Wind Energy Association (AWEA).
Instead, wind contributes to the stability of the grid, they say, and can be more reliable than conventional energy sources. Fluctuating supply and demand is fundamental to the grid - with or without wind power.
Fluctuations from any given power source are not what's important to grid operators, they care about the total supply and demand at any given moment. Variations in wind energy happen slowly and can be easily smoothed out - they are actually less problematic than fluctuations in conventional energy sources because they can be predicted in advance. And the more wind energy that's added to the grid, the less variable the resource as a whole becomes.
When conventional energy sources go down, they tend to drop suddenly and by a lot.
This means less - not more - reserve capacity is needed as a backup for intermittent wind. In Texas, grid operator ERCOT, for example, shows back-up for wind adds four cents to utility bills, compared to 76 cents for hedges against power plant outages, according to AWEA.
Out of 10 gigawatts of capacity, only 50 megawatts of fast-acting reserves must be ready to compensate for wind variations, says ERCOT. MISO, the grid operator in the Midwest, needs "little to no" fast-acting reserves. (http://www.freesmileys.org/emoticons/tuzki-bunnys/tuzki-bunny-emoticon-005.gif)
AWEA notes that wind variability does increase the need for more slower-acting reserves, but those are less expensive sources of power. (http://www.freesmileys.org/emoticons/tuzki-bunnys/tuzki-bunny-emoticon-005.gif)
"Conventional power-plant failures most often happen in a fraction of a second with no warning; the variability of wind is both gradual and predictable," Michael Goggin, AWEA's Research Director told Midwest Energy News. "Gradual changes in wind output are relatively easy for grid operators to accommodate. On the other hand, rapid changes in electricity supply caused by traditional power plant failures require very fast-acting reserve generation. 24/7, you don't know when a traditional power plant will go down. With wind you can do forecasting, you know tomorrow between 2 or 3 p.m. there will be a reduction." (http://www.freesmileys.org/emoticons/tuzki-bunnys/tuzki-bunny-emoticon-005.gif)
Therefore, AWEA says the focus on the need for large amounts of "baseload" power is misleading, as is the need for lots of energy storage. The combination of power sources on the grid serves that function. (http://www.desismileys.com/smileys/desismileys_0293.gif)
In fact, this is an argument for a diverse, balanced grid that runs on many energy sources. Wind energy helps build a more reliable and balanced electricity portfolio. (http://www.freesmileys.org/emoticons/tuzki-bunnys/tuzki-bunny-emoticon-005.gif)
More than a dozen studies by US grid operators and the Department of Energy show that wind energy can reliably supply at least 20-30% of our electricity, and some say, 40%. (http://www.pic4ever.com/images/47b20s0.gif)

World Wind Industry Grows 44% in 2014 ;D
2014 was a record-breaking year for the wind industry as it grew 44% worldwide, says the Global Wind Energy Council.
The industry added 51.5 gigawatts (GW) bringing the world cumulative total to 369.6 GW.
China, still the leader, set its own record by installing 23.4 GW - almost half the world's new capacity, and more than any country has added in one year. China has 115 GW of wind farms.
Europe added 12.8 GW, and Germany installed almost half of that with 5.3 GW of new wind, growing 58% from 2013. Germany now has 38 GW of onshore wind and 2.4 GW of offshore wind. Renewable energy currently supplies 25.8% of the country's electricity.
European countries are now connected to nearly 2,500 turbines as part of 74 different offshore wind farms, reports the European Wind Energy Association. Total installed capacity there reached 8,045.3 MW in 2014.
Other notable additions:
•US added 4.9 GW
•Latin America added 3.7 GW, mostly in Brazil (2.8 GW) - the significant newcomer
•India added 2.3 GW
Denmark had a watershed year, with wind producing 39% of its electricity, as did Scotland at 32%, and the UK, Spain, Portugal, and Germany get at least 10% from wind.
Wind energy now accounts for about 5% of global electricity demand.

High Tech wind power
Wind is every bit as reliable as coal and gas!
I think he meant the reliability systems are every bit as good as those used for coal and gas, not that wind was a reliable source of energy.
I think you are totally mistaken. Wind ENERGY IS AT LEAST as reliable as coal and gas.
Believe whatever you wish. I know I won't convince you. :emthdown: But if you really are serious about knowing the TRUTH, just go to Cleantechnica and they will calmly, and with LOSTS of mathematics and hard data, explain AND PROVE to you that wind IS MORE reliable than coal and gas. I get just a little tired of people like you assuming I post stuff here without GOBS of background and research to back up what I say BEFORE I say it. :emthdown:

Wind Power Is Cheaper, More Reliable, Than Natural Gas (http://cleantechnica.com/2014/10/28/wind-power-cheaper-reliable-natural-gas/)
The above is just ONE of many articles and nuts and bolts take downs of the MYTH that Coal (which is LESS RELIABLE THAN gas, by the way) and gas are more reliable than wind ENERGY. Amory Lovins has published peer reviewed articles in regard to wind energy reliability above and beyond coal, gas and nuclear.
Coal and gas are not cheaper than Wind energy either. And THAT is BEFORE any of the ENERGY costs of cleaning up the environment are Subtracted from COAL AND GAS EROEI.
Don't bother to apologize. I know that isn't your thing. ;)
Interesting quote from the article, which is essentially about wind in Oz:
“The whole point of putting renewables in, is to replace fossil fuel generation,” he said. “And obviously, the more generation you put into the system, more supply, always leads to lower cost of supply.”
In the case of South Australia, the added wind capacity has actually meant less reliance on back-up generation, demonstrating that grid volatility is not really increased when more renewables are added to the mix.
Needless to say, all this seems to be lost on the wind turbine hating Abbott government, and its mainstream media supporters.
Have been going up to Pennsylvania much lately, as my mother is not well. On the way I've often seen a billboard helpfully supplied by the local coal bund:
Part of the criticism of wind seems to be that it's intermittent. Whereas the point of the article is the contrast between models: a small amount of large generators as opposed to a large number of small generators. The article makes the point that the latter is more resilient. (http://www.pic4ever.com/images/128fs318181.gif)(http://www.desismileys.com/smileys/desismileys_0293.gif) The fossil fuel crowd hates this, of course.
Thank you Surly and Eddie for showing objectivity (that Palloy REFUSES to show) in this issue of Wind Energy Reliability. (http://www.runemasterstudios.com/graemlins/images/2thumbs.gif)
On another thread today you said you agreed with me 100%, and I agree with you 100% sometimes too. I have no problem with you being a Christian. I disagree with your ideas on evolution, and tried to discover some common ground on that, however small, but you didn't want to pursue that.
This seems to cover what Lovins says:
He is talking about:
1. making changes to the overall demand, to lower it by about 44% at peak
2. making changes to the sub-daily variation in demand, to smooth it out by about 66%
3. using wind, solar and dispatchable geothermal, hydro and feedlot biogas
4. storing excess in high-storage air-conditioning and EV batteries
5. "unobtrusively flexible demand" for load matching
The unreliability of coal is deemed to be that "they break sometimes". (And wind turbines don't?) ::)
The changes he talks about as being so easy are massively complicated to achieve in practice. (http://www.desismileys.com/smileys/desismileys_2932.gif)
You have boiled all that down to "wind is more reliable than coal", which is why the statement in isolation looks so odd.
I think you ought to take stock of why you are so hostile to anyone who questions the things you say, when those things are so obviously wrong - the pent up aggression will give you a heart attack in the end. (http://www.desismileys.com/smileys/desismileys_2932.gif) :evil4:
Thank you for posting some of Amory's points. I agree with all of them. NO, he is NOT saying that the unreliability of fossil fuel power plants is strictly a function of an occasional breakdown. That is a deliberate misinterpretation of the data on your part. (http://www.desismileys.com/smileys/desismileys_6869.gif)
Oh, yes, the "You are too sensitive" accusation. ::) I'm "hostile" to incorrect interpretations, sloppy biosphere math and biased defenses of dirty energy because they are not objective.
YOU are the one who wouldn't let it go when I said I disagreed with you. You could have, but you didn't. I heard you the first time you said you disagreed with my "interpretation" of the video. But you had to push it. when somebody pushes me, I roll over if I'm wrong. But if I'm right, I pack a sandwich and dive into the fray. I'm right, so just like Uncle Sam, I say, KNOCK KNOCK, HERE I AM! (http://www.pic4ever.com/images/2mo5pow.gif) (http://www.pic4ever.com/images/swear1.gif)
ALL of your arguments, when you aren't going for psychological manipulation or snark ad hominem, are based on a cherry picked type of math that factors out ENERGY costs not directly involved in the operation of a power source BEFORE it is built, WHILE it is being built and AFTER the damage it has done to the environment MUST be dealt with in decommissioning and health care costs. I don't think you are being mathematically myopic because you don't know any better.
IF you were an ignoramus, I would not come at you like a freight train when you play these games. But you are a smart man and you influence people to believe status quo EROEI myths (see Charles Hall and fossil fuel friends :evil4:). I had the same problem with Roamer. You guys are SUCKERED into the BIG POWERFUL INTERNAL COMBUSTION CONCENTRALIZED ENERGY BULLSHIT. It was taught to you in schools. You are biased. You are wrong. Your "view" of energy CFS is helping DESTROY LIFE ON EARTH. That is, to put it mildly, something I resent.
Your snarky rejoinder to Amory, "And wind turbines don't? (break down as often as fossil fuel power plants) CONVENIENTLY ignores the MASSIVE redundancy factor (ABSENT FROM LARGE CENTRALIZED FOSSIL FUEL POWER PLANTS) inherent in having MULTIPLE wind turbines with 24/7 VARYING wind loads that TRANSLATE, using modern technology, to MORE RELIABLITY. Now it's my turn for snark! Mathematicans really should learn to count power plants! FOR EXAMPLE ONLY, 10,000 or more wind turbines, with 50 breaking down per year, versus 2 or three fossil fuel power plants, with one breaking down per year. DO THE RELIABILITY MATH, MATHEMATICIAN. 8)
Palloy, I, unlike you, will jump out there and say I agree with you 100% when I applaud what you write. Much of what you write is good stuff. :emthup: Don't pretend you didn't WALK AWAY form the DNA degraded wolf = dog debate that YOU asked me to engage in, SPECIFICALLY because you thought you could trounce me with your knowledge of dog breeding ;). I consider walking away from a debate, where one party has posted irrefutable research to defend his position ;D, behavior typical of a sore loser. :emthdown:
You consider that the behavior of someone who plays to win and leaves the game before the score is "settled". Maybe that's okay for someone who's religion is the "apex predators are all sneaky = highly evolved status" CHURCH OF EVOLUTION DOGMA. But that is a questionable moral calculus, Mr. Mathematician.
But thanks anyway, for admitting that you DO agree with me sometimes, even if it was for the specific purpose of defending your biased view that wind energy is less reliable than fossil and nuclear piggery. ;) Any port in the storm and all that. :emthup:
Now for today's Renewable Energy News:04/28/2015 03:54 PM
Stanford Leads With Massive Renewable Energy System
Stanford University announced a massive upgrade to its energy system that makes it a world leader among universities, while saving $420 million on energy costs over the next 35 years.
There are two components - an extremely efficient combined heat and power system (CHP) and lots of solar energy. (http://us.123rf.com/400wm/400/400/yayayoy/yayayoy1106/yayayoy110600019/9735563-smiling-sun-showing-thumb-up.jpg)
SunPower is installing 5 megawatts (MW) of rooftop solar on campus and a 68 MW project on 300 acres of land - a commitment only exceeded by University of California. Combined with purchases of renewable energy from the grid, the projects will generate 65% of Stanford's electricity.
On the efficiency side, Stanford will cut emissions 68% and conserve 15% of potable water through its CHP plant, Stanford Energy Systems Innovations (SESI). An amazing 90% of campus heat will be supplied by recovering waste heat from the system that chills water on campus.
22 miles of underground pipes had to be replaced and 155 buildings were retrofitted to convert from the old steam cogeneration system that ran on natural gas. Stanford essentially created a District Energy system, common in Europe, but rare in North America.
Construction started in 2012 and the $438 million project began operating in March.
Stanford patented the software that optimizes the system. It continuously monitors plant equipment, predicts campus energy loads and grid electricity prices, and steers the system to using energy at the most economical times. It also continuously reviews its own performance.
"SESI is designed to take advantage of Northern California's temperate climate, although the system is adaptable to nearly any environment. As with most modern large commercial facilities, university buildings are being cooled and heated at the same time throughout the year to supply different room-temperature requirements.
"In other words, the cooling process can be seen as a collection of unwanted heat. Some modern facilities take advantage of this heat overlap on a stand-alone building basis. SESI, however, takes this approach to an entirely new scale, encompassing a 15-million-square-foot campus with a population of more than 30,000.
"By significantly reducing natural gas usage and electrifying the campus heating and cooling system, we enabled the university's energy supply to be substantially transitioned from fossil fuels with volatile and unpredictable long-term prices to clean renewable electricity sources with affordable costs fixed for a very long time," says Joseph Stagner, executive director of Sustainability and Energy Management at Stanford. (http://www.freesmileys.org/emoticons/tuzki-bunnys/tuzki-bunny-emoticon-005.gif)
Under Stanford's ongoing Energy and Climate Action Plan, new buildings must be 30% more efficient than state code - which already leads the nation. Existing buildings are getting major retrofits and campus programs teach students, faculty and staff how to cut back on their energy use.
Last year, Stanford announced it would divest from coal, the first major university to do so. ;D

The Future of Wind Turbines? No Blades (http://www.coh2.org/images/Smileys/huhsign.gif)
Caption: The company designing the machine says its turbine is cheaper to manufacture, silent and doesn't pose a thread to birds. Vortex Bladeless
It’s no longer surprising to encounter 100-foot pinwheels spinning in the breeze as you drive down the highway. But don’t get too comfortable with that view. A Spanish company called Vortex Bladeless is proposing a radical new way to generate wind energy that will once again upend what you see outside your car window.
Their idea is the Vortex, a bladeless wind turbine that looks like a giant rolled joint shooting into the sky. The Vortex has the same goals as conventional wind turbines: To turn breezes into kinetic energy that can be used as electricity. But it goes about it in an entirely different way.
Instead of capturing energy via the circular motion of a propeller, the Vortex takes advantage of what’s known as vorticity, an aerodynamic effect that produces a pattern of spinning vortices. Vorticity has long been considered the enemy of architects and engineers, who actively try to design their way around these whirlpools of wind. And for good reason: With enough wind, vorticity can lead to an oscillating motion in structures, which, in some cases, like the Tacoma Narrows Bridge, can cause their eventual collapse.
Where designers see danger, Vortex Bladeless’s founders—David Suriol, David Yáñez, and Raul Martín—sees opportunity. “We said, ‘Why don’t we try to use this energy, not avoid it,’” Suriol says. The team started Vortex Bladeless in 2010 as a way to turn this vibrating energy into something productive.
A prototype of the Vortex. Vortex Bladeless
The Vortex’s shape was developed computationally to ensure the spinning wind (vortices) occurs synchronously along the entirety of the mast. “The swirls have to work together to achieve good performance,” Villarreal explains. In its current prototype, the elongated cone is made from a composite of fiberglass and carbon fiber, which allows the mast to vibrate as much as possible (an increase in mass reduces natural frequency). At the base of the cone are two rings of repelling magnets, which act as a sort of nonelectrical motor. When the cone oscillates one way, the repelling magnets pull it in the other direction, like a slight nudge to boost the mast’s movement regardless of wind speed. This kinetic energy is then converted into electricity via an alternator that multiplies the frequency of the mast’s oscillation to improve the energy-gathering efficiency.
Its makers boast the fact that there are no gears, bolts, or mechanically moving parts, which they say makes the Vortex cheaper to manufacture and maintain. The founders claim their Vortex Mini, which stands at around 41 feet tall, can capture up to 40 percent of the wind’s power during ideal conditions (this is when the wind is blowing at around 26 miles per hour). Based on field testing, the Mini ultimately captures 30 percent less than conventional wind turbines, but that shortcoming is compensated by the fact that you can put double the Vortex turbines into the same space as a propeller turbine.
The Vortex team says there are some clear advantages to their model: It’s less expensive to manufacture, totally silent, and safer for birds since there are no blades to fly into. Vortex Bladeless says its turbine would cost around 51 percent less than a traditional turbine whose major costs come from the blades and support system. Plus, Suriol says, it’s pretty cool-looking. “It looks like asparagus,” he says. “It’s much more natural.”
The company has already raised $1 million from private capital and government funding in Spain, and they have plans to close a round in the United States soon. There’s enough interest, Suriol says, that he fields upward of 200 emails a day from people inquiring about the turbine. Of course, the technology still has a ways to go. They’re hoping to have their first product, a 9-foot, 100-watt turbine that will be used in developing countries, ready before the end of the year. The Mini, it’s 41-foot counterpart, will be ready in a year.
For the time being, you’ll continue seeing pinwheels dotting the landscape, which Suriol is actually happy about. “We can’t say anything bad about conventional wind turbines; they’re great machines,” he says. “We’re just proposing a new way, a different way.”
MAP: Energy Dept. finds there can be wind energy in every state
The U.S. wind industry can virtually rewrite America’s wind resource map with its advancing technology so that wind energy development eventually comes to every state in the nation.
That was the news delivered directly to WINDPOWER attendees by U.S. Secretary of Energy Ernest Moniz and detailed in a report titled “Enabling Wind Power Nationwide” that featured several new wind potential maps. This follow-up report to the Department of Energy’s Wind Vision was released in conjunction with the WINDPOWER 2015 Conference & Exhibition.
“By producing the next generation of larger and more efficient wind turbines, we can create thousands of new jobs and reduce greenhouse gas emissions, as we fully unlock wind power as a critical national resource,” Moniz said in a statement upon release of the report.
In his WINDPOWER General Session address, Moniz expressed the need for investment in high-voltage transmission development, which he pointed out is achievable as it “is in no way out of bounds with current investment levels.” He pointed out DOE is also involved in aiding with industry-specific challenges—for example, the logistics of moving ever-larger wind components to project sites.
He pointed out DOE is also involved in aiding with industry-specific challenges—for example, the logistics of moving ever-larger wind components to project sites.
He stated that international climate commitments align with the numbers the wind industry can contribute as detailed in the Wind Vision, which outlines how America can double its wind energy penetration to 10 percent by 2020, double it again to 20 percent by 2030, and then reach 35 percent by 2050.
“If you do that arithmetic, you can see how this fits into the [Wind Vision] in terms of robust deployment of wind to 2020,” he said. “But, because those targets we laid out actually call for doubling the pace of carbon reductions beyond 2020, that idea of wind deployments for example, upping the ante after 2020 just fits hand in glove with those kinds of targets that we laid out.”
Moniz spoke both near- and long term, urging extension of the federal Production Tax Credit and setting sights on wind energy contributing 1 trillion kilowatt-hours a year, which he called “a nice target—a nice, round number” to pursue, even though it may take a decade or more to get there.
AWEA CEO Tom Kiernan spoke earlier in the session about the Wind Vision, likening pursuit of its benchmarks to the challenges and ultimate success of the 1990 Clean Air Act, which he worked on under the George H.W. Bush administration. Kiernan initiated what became a theme of the General Session—a clear call to action for members of the industry to let their voices be heard at a decibel level matching the size and importance of the industry. He urged the men and women working in wind energy to join AWEA (firstname.lastname@example.org), join powerofwind.com, speak publicly on behalf of the industry by becoming a Wind Ambassador, and donate to a wind-related political action committee.
“The future of our industry, I believe the future of America, is dependent upon what we do now,” said Kiernan. (http://www.desismileys.com/smileys/desismileys_0293.gif)
Wind’s contribution to America was evident across the entire General Session. Lisa Davis of Siemens AG shared the contribution of veterans in Siemens’ wind operations all around the country, from its North American headquarters in Orlando to its facilities in Hutchinson, Kan., Ft. Madison, Iowa and elsewhere. She also highlighted wind’s arrival as a mainstream energy source that’s making a difference in so many ways.
“Ladies and gentlemen, wind power is now in the United States,” she said.
The General Session got down to business with an industry panel that built off of the news coming from Moniz and DOE as well as other speakers. Providing the DOE perspective to the otherwise all-industry panel was Jose Zayas, the Director for Wind & Water Power Technologies Office who has been at the center of the Wind Vision initiative. Echoing Moniz on a few issues, such as transmission infrastructure, Zayas reiterated the latest report’s finding, saying, “I hope one day we can sit here and talk about having wind in every state.”
Paul Gaynor, the Executive Vice President at SunEdison who helped grow a wind energy company based largely on a strategy of developing high-value projects near load, appropriately spoke to the notion of the expanding geographic potential for wind highlighted by the DOE report. “To me, it’s an opportunity to think about the country a little bit differently,” he said.
Panelists also touched on the broader wind energy market going forward and the impact of various factors such as the U.S. Environmental Protection Agency’s pending Clean Power Plan to cut carbon emissions in the electric sector. Karen Conover, Vice President at DNV GL, observed that wind is “most economic” in many of the places where carbon reductions may be most needed.
RES Americas President Susan Reilly addressed the advocacy dimension of the Clean Power Plan as the implementation details get worked out. She urged that the industry convey how “wind energy can be a very competitive compliance measure” for meeting the Clean Power Plan requirements.
Technology advancement was a major topic of the General Session, and the comments of Anne McEntee, Vice President for Renewables at GE Power & Water, epitomized the theme. “We are right now, through the industrial internet, going through a massive transformation,” said McEntee. She discussed GE’s “Digital Wind Farm,” announced today, which maximizes turbine efficiency at a project site by using the power of big data and real-time information to change hub heights and perform other measures.
Doug Greenholz, President of IKEA Property Inc., closed out the session with some firsthand information from the ever-growing number of companies buying wind. “Wind is limitless, renewable, and free, and it helps keep costs down,” he said.
And, Greenholz said, wind energy is in sync with the company’s core value of having a positive impact on people’s lives—in this case by incorporating sustainable practices.
IKEA’s plan is to produce more renewable energy than it uses in its operations by 2020, according to Greenholz. (http://www.createaforum.com/gallery/renewablerevolution/3-200714191258.bmp)
What makes owls deadly could make wind turbines silent
By Suzanne Jacobs on 22 Jun 2015
Owls — those whimsical and deadly hunting machines that crafty people love and Harry Potter characters employ as postal workers — have the unusual ability to fly in (virtual) silence. That’s bad news if you’re a delicious-looking rodent minding your own business, but it’s good news if you’re a scientist looking for a way to silence noisy wind turbines.
Nigel Peake, a professor of applied mathematics and theoretical physics at the University of Cambridge, happens to be one of those scientists. And by using a 3D-printed material meant to mimic the surface of owl wings, he and his colleagues were able to lower the noise level of a wind turbine blade by about 10 decibels. (For comparison: The typical wind turbine a few hundred yards from a house will come in around 40 decibels, about as loud as the in-house refrigerator, according to GE.)
Here’s more from a press release out of the University of Cambridge:
Peake and his collaborators at Virginia Tech, Lehigh and Florida Atlantic Universities used high resolution microscopy to examine owl feathers in fine detail. They observed that the flight feathers on an owl’s wing have a downy covering, which resembles a forest canopy when viewed from above. In addition to this fluffy canopy, owl wings also have a flexible comb of evenly-spaced bristles along their leading edge, and a porous and elastic fringe on the trailing edge.
“No other bird has this sort of intricate wing structure,” said Peake. “Much of the noise caused by a wing – whether it’s attached to a bird, a plane or a fan – originates at the trailing edge where the air passing over the wing surface is turbulent. The structure of an owl’s wing serves to reduce noise by smoothing the passage of air as it passes over the wing – scattering the sound so their prey can’t hear them coming.”
Peake and his collaborators first experimented with a wedding veil-like material, which they found could reduce the noise level of a turbine blade by up to 30 decibels. But that material wasn’t practical for real-world applications, so they turned to 3D-printed plastic:
Early tests of the material, which mimics the intricate structure of an owl’s wing, have demonstrated that it could significantly reduce the amount of noise produced by wind turbines and other types of fan blades, such as those in computers or planes. Since wind turbines are heavily braked in order to minimize noise, the addition of this new surface would mean that they could be run at much higher speeds – producing more energy while making less noise. For an average-sized wind farm, this could mean several additional megawatts worth of electricity. (http://www.createaforum.com/gallery/renewablerevolution/3-080515182559.png)
The silence of owl flight (good movie title?) is not a revelation, but how owls manage it is. And if you don’t believe that they do, just check out this PBS video (http://www.pic4ever.com/images/19.gif), where Kensa the owl squares off against Smudge the “urban opportunist” pigeon and Moses the “king of speed” peregrine in a quiet fly-off:
Owl, pigeon and falcon flight sounds compare Video at link;
Agelbert NOTE: For those concerned that more birds will be killed if the wind turbine blades make less noise, I think you are right. I also think that putting self wind powered led lights along the leading edge of the blades at reasonable intervals (every ten feet or so) will PERMANENTLY drop bird deaths day and night to near zero. The led lights, WITHOUT any batteries whatsoever for low maintenance costs and high longevity, would NOT light up when the wind is dead. They would get brighter as the velocity of the wind over the blades increased. The birds would quickly learn to interpret the brightness as a danger signal. Eyesight is the most developed sense in a bird. We should help them use it to avoid danger.
Self powered tiny wind generators are old technology. I flew planes that you could pop out a six inch diameter propeller for emergency electricity for onboard systems in the event of electrical failure. It's child's play to put really cheap versions of these things (all they have run is their LED!) on wind turbines cheaply! (http://www.createaforum.com/gallery/renewablerevolution/3-200714191456.bmp)

Billionaire On Way To Building Largest Wind Farm In North America… And It’s Not Warren Buffett

There's an interesting back story to this...
"In 2006, Bill Miller was about to sell his boss’ cattle ranch, a 500-square-mile high-desert expanse in south-central Wyoming. A buyer was prepared to pay roughly $50 million for it. But something was gnawing at Miller. Every time he visited the place, called the Overland Trail Ranch, the wind there blew so fiercely he had to brace against it just to stay upright.
Miller’s boss, Philip Anschutz, had become one of the richest men in America—with a fortune of nearly $12 billion—by figuring out an abundance of ways to churn wealth out of real estate, from oil wells and railroads to sports arenas and cattle ranches.
One morning in 2006, as Miller stood on the barren bluffs of the Overland Trail Ranch, thinking about the sale of the property, he sensed an opportunity.
Miller was soon sitting in Anschutz’s 24th-floor office, which has a sweeping view of Denver, the high desert, and the Rocky Mountains beyond. The two of them knew that the market for wind energy was growing, and that other oil and gas companies had been poking around Wyoming’s windy corners. “I know we’re trying to sell this ranch,” Miller told his boss, “but we may have something here. So why don’t we peel this orange and see what we get?”
Anschutz, who reads widely about energy markets, seized on the idea at once. Though the pair didn’t realize it at the time, they were about to hatch plans for the largest single onshore wind farm in the world.
The winds of West Texas, home to some of the nation’s largest wind farms, are Class 4. Most wind power in these places is generated at night, when the winds blow the hardest; that’s the time, of course, when people need it the least.
But along the ridges of the Overland Trail Ranch are some of the only Class 7 winds in the nation. What’s more, the wind on the ranch starts up in the morning and gains force throughout the day, just when people are firing up their air conditioners and dishwashers. “We looked at the data and said, ‘I’ll be damned,’” Miller recalls. The property was like the Saudi Arabia of wind." (http://www.4smileys.com/smileys/seasons-smileys/storm.gif) (http://www.createaforum.com/gallery/renewablerevolution/3-200714191258.bmp)

Solar Wind Energy Tower, Inc. Provides Update on Mexico Tower Project
Published: July 7, 2015 8:30 a.m. ET
Tower Development and Water Permits Formally Extended to June 30, 2016
ANNAPOLIS, MD , Jul 7, 2015 (Marketwired via COMTEX) -- Solar Wind Energy Tower, Inc. (otcqb:SWET) (the "Company"), the inventor of large Solar Wind Downdraft Tower structures capable of producing abundant, inexpensive electricity, today announced that its operating subsidiary, Solar Wind Energy, Inc. has executed an extension of its right to purchase a site in San Luis Rio Colorado, Sonora, Mexico, which will support up to two energy Towers. The Mexico site is located approximately 6 miles from the Tower site in San Luis, Arizona and experiences identical climate conditions allowing both to use the same development plans and equipment.
In order for the Tower(s) to be developed in Mexico, the national utility "Comision Federal de Electricidad" must sign a long term Power Purchase Agreement with the Company. Solar Wind Energy formally introduced the project to the commission and presented preliminary project data and specifications to the commission earlier this year. The seller of the land, anticipating an upcoming meeting to discuss the specifics of the project, offered a free contract extension through June 30, 2016 to close on the sale.
On June 30, 2015, the City of San Luis Rio Colorado supplied a support letter that extended their previous approvals to permit the project and supply the necessary water to the project for 50 years. The previous approvals were set to expire June 30, 2015 and have now been formally extended to June 30, 2016.
Ron Pickett, CEO of Solar Wind Energy Tower, commented, "On June 24th I personally met with the government liaison for the San Luis Rio Colorado project. In our meeting I was provided with a thorough project status update and an explanation that recent delays were unavoidably related to new energy policies and elections. After that meeting, it was clear that the Tower project remains viable in San Luis Rio Colorado. We're pleased to continue to move forward after receiving formal extensions from the property owner and local government. The date set for ground breaking if the utility decides to move forward is now June 30, 2016. We are encouraged by the cooperation of all concerned parties and look forward to securing the PPA needed to support the financing of this project."

Siemens Plans To Construct a New Wind Turbine Assembly Plant in Germany
June 30, 2015
By Alex Webb, Bloomberg
Siemens AG’s plan to build a wind turbine assembly plant in Germany means that Europe’s largest engineering company will have expanded headcount at its wind and renewables division by as much as a third since 2013.
Siemens will pick a location for the 1,000-employee factory by the end of September, spokesman Philipp Encz said by telephone. Earlier announcements of new capacity in Egypt, England and Serbia will bring the total new employees to 3,539, according to Bloomberg News calculations.
“If they’re expanding for offshore, it does imply they have a view of a strong pipeline in future, which is good for the industry, because there’s a lot of uncertainty post-2020,” said Tom Harries, a London-based Bloomberg New Energy Finance analyst.
Given the Munich-based company said its wind division had 10,900 employees in November 2013, it will have added a further 32 percent to that worker base by the time all the new facilities are completed. While the expansion is part of Chief Executive Officer Joe Kaeser’s move to bring production closer to customers, some employees at existing sites will not be replaced should they leave or retire, Encz said.
Orders at the wind business jumped by 57 percent between September 2012 and September 2014 to 7.7 billion euros ($8.6 billion).
The new capacity comes as Kaeser slashes 13,100 jobs elsewhere, with the power and gas division, which makes gas turbines, bearing the brunt of the manufacturing cuts.
Siemens currently has seven production sites making onshore and offshore wind turbines, stretching from Shanghai to Iowa via Denmark and Canada. Kaeser first announced plans for the German plant in an interview with the Frankfurter Allgemeine Zeitung newspaper.

Denmark's wind power just exceeded their energy demand (http://www.pic4ever.com/images/za4.gif)
by Walter Einenke for weinenkel.
Yesterday, Denmark's wind farms were able to produce 116% of the nation's electricity needs.
By 3am on Friday, when electricity demand dropped, that figure had risen to 140%.
Interconnectors allowed 80% of the power surplus to be shared equally between Germany and Norway, which can store it in hydropower systems for use later. Sweden took the remaining fifth of excess power.
“It shows that a world powered 100% by renewable energy is no fantasy,” said Oliver Joy, a spokesman for trade body the European Wind Energy Association. “Wind energy and renewables can be a solution to decarbonisation – and also security of supply at times of high demand.”
Wow. Very cool. Very windy. ;D

An industrial revolution is sweeping over Heligoland, a tiny German North Sea archipelago once annexed by the British, and a haven for bird watchers until the wind farmers moved in two years ago.
Units of Blackstone Group LP, EON SE and RWE AG have opened offices and warehouses at the main island’s southern port, taking 25-year leases as they start feeding electricity from three new farms into Germany’s growing reservoir of renewable energy.
“Offshore is a blessing for our island,” said Peter Singer, the 51-year-old head of Heligoland’s port project company. “Commercial tax revenue has risen by 50 percent in the last two years.”
Singer, whose roots on the island go back to the 19th century, led a team that spent a year clearing the harbor of 1,300 bombs, grenades and bullets, remnants of two world wars. That has helped transform Heligoland, dependent on daytrippers seeking tax-free liquor and tobacco, into an offshore service hub for the wind turbines that now pepper the horizon.
About 100 wind farmers have joined the 1,400 population, recognizable in their bright red overalls. Managers in business attire, once as rare as the black-browed albatross that sporadically visits its distinctive red cliffs, have also become a regular feature.
EON is racing to complete construction of the 288-megawatt Amrumbank West wind farm 35 kilometers (22 miles) to the north before winter. Crews of 12 will then set out every morning to carry out maintenance and repairs on the 80 Siemens AG wind turbines rotating in the often inclement waters.
Proximity to Heligoland saves EON’s staff the 44-mile daily shuttle from the coast and means they don’t have to sleep aboard hotel vessels common at other wind farms, says Sven Utermoehlen, the head of the company’s global offshore business.
As Germany makes headway with its goal to generate as much as 45 percent of its power from renewables by 2025, EON and its competitors are installing a total of 208 turbines, each spending about 1 billion euros ($1.1 billion) on the endeavor.
Some 170 wind mills are rotating, with undersea grid cables spanning a distance of about 90 kilometers that connect the generators to the mainland, producing enough power to serve 900,000 households for as long as 25 years. (http://www.createaforum.com/gallery/renewablerevolution/3-200714191258.bmp)
“Heligoland is a very convenient accommodation platform for us, little more than an hour away by ship from the wind farm,” said Hans Buenting, the head of RWE Innogy, whose 295-megawatt Nordsee Ost farm operates turbines supplied by Senvion SE.
Exposed to battering waves and salt water, wind power plants typically need five days a year for maintenance, excluding unforeseen repair work. (http://www.createaforum.com/gallery/renewablerevolution/3-080515182559.png)
Singer estimates the boom will bring in more than 100 new jobs. While most of the recruits will come from the mainland as tasks at sea demand specially trained staff, some islanders are gaining employment.
“Some are finding positions as captains or nautical officers, others can do refueling and mooring tasks,” he said.
Still, emigration is a drain on the local economy. Young islanders leave to pursue education and apprenticeships further afield.
Except for a short-lived boom after the fall of the Berlin Wall, when East Germans flocked to the islands, tourism has slumped. Last year, it counted just 316,000 guests, a far cry from 830,000 in its heyday in the 1970s.
“We can’t compete against low-cost flights to Mallorca for 80 euros or 90 euros,” said Singer. Prices for a return ferry ticket from Hamburg to Heligoland range from 69 euros to 145 euros.
His gold-rush spirit hasn’t yet spread to all the islanders.
“Many still view the offshore-story as alien,” said Werner Feuerhake, a 63-year-old technician. “In the past, people caught fish, now they catch the wind. That’s positive, but we need to sharpen people’s awareness of that.”

100-MW Kenyan Wind Farm Will Help Power Africa ;D
With a $233 million grant from U.S. Development Finance Institution, OPIC will support a 100-MW, grid-connected wind energy facility south of Nairobi.
July 27, 2015
I have been out on the North Sea, and know the hazards and problems involved in offshore maintenance. There are very few independent maintenance companies in the European offshore industry. And the big customers for European offshore wind parks, are usually semi-state owned, state-owned and municipally owned utilities that are not necessarily dependent upon a double digit ROI.
Another comment by the author I disagree with was that merely extending blade length increased turbine capacities. I have watched German large turbine capacities jump from 100 kw in 1982 with the German "Growian" grow to over 8 gw with the German Enercon, or 6 gw offshore with the Siemens SWT 6.
Those increases were due to massive improvements in magnet technology- which boosted generator efficiencies, improvements n blade configuration, increases in tower height, reinforcing the increased height towers to accommodate the weight and forces on top of the tower, plus the increasing blade lengths and new blade configuration.
Let us name names. Siemens and Vestas are the top 2 in offshore wind turbine - wind park construction. Their long term O.E.M. construction and maintenance contracts with the semi-state owned, state-owned, and municipally owned utilities have the advantage of low prices through volume, economies of scale, that smaller independent service and maintenance companies cannot achieve. The men and women who work for Vestas and Siemens Wind maintenance departments are top professionals with an eye to both quality work and safety, and are under no pressure "from executives" to deliver "double digit" profits.
Smaller companies competing in the offshore wind maintenance sector do not have economies of scale, and would have to cut corners in safely and quality. Actually, for the semi-state owned and state owned utilities that are the ones that are the project owners of European offshore- the 15 year "photocopy " O.E.M. maintenance and service contracts are the most cost effective option.

New Installations Usher in Lowest Wind Energy Prices to Date (http://www.freesmileys.org/emoticons/tuzki-bunnys/tuzki-bunny-emoticon-022.gif)
Washington, D.C. -- According to two reports released today by the Energy Department, the U.S. wind energy industry continued growing at an impressive rate in 2014, further solidifying America’s position as a global leader in wind energy. Wind power is a key component of the President’s all-of-the-above energy strategy and Clean Power Plan to reduce climate-changing carbon pollution, diversify our energy economy, and boost America’s economic competitiveness by bringing innovative technologies online. With rapidly increasing wind energy generation, fast-growing demand, and steadily decreasing wind energy prices—the lowest ever seen in the United States— the U.S. wind energy market remains strong.
“With declining costs and continued technological development, these reports demonstrate that wind power is a reliable source of clean, renewable energy for American homes and businesses,” said Energy Secretary Ernest Moniz. “Through continued investments and the help of stable policies, we’re confident that wind power will keep playing a major role in creating jobs and shaping America’s clean energy future.”
WIND TECHNOLOGIES MARKET REPORT
According to the 2014 Wind Technologies Market Report released today by the Energy Department and its Lawrence Berkeley National Laboratory, total installed wind power capacity in the United States grew at a rate of eight percent in 2014 and now stands at nearly 66 gigawatts (GW), which ranks second in the world and meets 4.9 percent of end-use electricity demand in an average year. The United States was the global leader in total wind energy production in 2014. The report also finds that wind energy prices are at an all-time low and are competitive with wholesale power prices and traditional power sources across many areas of the United States.
A new trend identified by the report shows utility-scale turbines with larger rotors designed for lower wind speeds have been increasingly deployed across the country in 2014. The findings also suggest that the success of the U.S. wind industry has had a ripple effect on the American economy, supporting 73,000 jobs related to development, siting, manufacturing, transportation, and other industries—an increase of 22,500 jobs from 2013 to 2014.
DISTRIBUTED WIND MARKET REPORT
In total, U.S. turbines in distributed applications reached a cumulative installed capacity of more than 906 megawatts (MW)–enough to power more than 168,000 average American homes–according to the 2014 Distributed Wind Market Report, also released today by the Energy Department and its Pacific Northwest National Laboratory. This capacity comes from roughly 74,000 turbines installed across all 50 states, Puerto Rico, and the U.S. Virgin Islands. Compared with traditional, centralized power plants, distributed wind energy installations supply power directly to the local grid near homes, farms, businesses, and communities. Turbines used in these applications can range in size from a few hundred watts to multi-megawatts, and can help power remote, off-grid homes and farms, as well as local schools and manufacturing facilities. (http://www.smile-day.net/wp-content/uploads/2011/12/Smiley-Thumbs-Up2.jpg)
As shown in the report, America's distributed wind energy industry supports a growing domestic industrial base. U.S.-based small wind turbine manufacturers claimed another strong year of exports to countries across the globe, accounting for nearly 80 percent of U.S.-based manufacturers’ sales.

Agelbert NOTE: Since I know a thing or two about "how it works" in Puerto Rico, let me say that wind power was destroyed there when NASA put up a successful giant two bladed turbine on an outlying island municipality called Culebra (see quoted yours truly post from 2013 after this post).
It worked great but the fossil fuel government owned utility Fuentes Fluviales, EXCLUSIVELY powered by fossil fuels, REFUSED to take the turbine given to it FREE by NASA because, uh, uhm, of "maintenance" costs...

Some of you may have heard about the trade winds. Down in Puerto Rico they are known as the "Vientos Alicios" (Prevailing Easterlies). They are NOT intermittent. They NEVER stop. The Earth needs to stop rotating for them to stop. IOW its CFS for the ALL the Caribbean Islands to use WIND power 24/7 along with solar from the HUGE insolation factor they get on top of that. But it was not done BECAUSE of fossil fuel industry influence. (http://www.createaforum.com/gallery/renewablerevolution/3-200714191329.bmp)
It's almost forty years late, but finally, wind power and solar is taking hold in the Caribbean. Better late than never, I always say. (http://www.freesmileys.org/emoticons/emoticon-object-062.gif)
For those who labor under the view that the reversal of fortunes for Renewable Energy in the early 1980s was just ignorance, supply and demand and big oil wasn't INSTRUMENTAL in bringing it about.
Oh, and about NON-HYDRO renewable energy being THROTTLED shortly after the technology was proven competitive with fossil fuels. You mean you DIDN"T KNOW there was SIGNIFICANT PROMISING RENEWABLE ENERGY NON-HYDRO COST COMPETITIVE TECHNOLOGY BEFORE 1980? ???
I understand that the media BURIED the FACT that IT HAPPENED TO WIND TURBINE TECHNOLOGY shortly after 1980 when Carter left office!
It was SHELVED -DEEP SIXED - LEFT TO DIE UNTIL RESURRECTED in the mid to late 1990s BUT NOT BY THE USA!
The GREATEST PENETRATION OF PURE HYDRO renewable energy in the USA was in 1940.
Over 1500 hydroelectric facilities produce about one third of the United States' electrical energy.
It was ALL DOWN HILL FOR HYDRO AS A PERCENTAGE of electrical energy generated FROM THEN ON.
The NEW CSP, wind turbine and, to a lesser but still important extent PV technologies, were being assiduously developed during the late 1970s.
Power companies closed ranks AGAINST that technology. Even places WITHOUT electricity like a Navajo Reservation in New Mexico triggered angry letters from the utility to NASA to STOP putting solar panels for water pumping there because it COULD "force electrical rates DOWN IN THE FUTURE". NASA STOPPED but Carter kept pushing until 1980. GET IT?

Wind Energy Comes of Age
By Paul Gipe
After the moon landings, the space program began winding down, and with it the space agency.
NASA was scrambling to redefine itself, to find new "missions," when opportunity struck in the form of the oil embargo.
What began as mere tinkering by researchers at the agency's Lewis research center near Sandusky, Ohio quickly evolved into the most costly wind energy R&D program in the world.
NASA began translating all known documents on wind energy worldwide. They consulted with Hutter and Putnam and studied the operation of Juul's machine at Gedser. In the end they started down a path blazed years before by Putnam. The result, the Mod-0, resembled neither Hutter's lightweight, flexible, downwind design nor Juul's rigid thee bladed upwind design. NASA's Mod-0 incorproated none of the lessons of Europe, while abandoning Putnam's most significant design element, his hinged blades.
Westinghouse, the contractor on the Mod-0, was subsequently hired to build an uprated version, the Mod-0A, for extended field tests. Four Mod-0A prototypes were installed (Puerto Rico, New Mexico, Hawaii & Rhode Island).
All were sc****d when none of the host utilities wanted to assume maintenance of the turbines.
The book goes on to explain, in detail, how various R&D goals of a high MTBF "couldn't seem to be achieved" in order for these machines to be considered "reliable". (http://www.createaforum.com/gallery/renewablerevolution/3-200714191329.bmp)
They could build rockets to the moon, supersonic aircraft, high speed jet turbines with micrometer tolerances but making gears, housings and transmissions for a glacially slow giant propeller to generate electricity was just "too hard".

Image: scottish-enterpriseWind Generates Third of Scotland’s Electricity Demand in June
In June, wind power generated a third of Scotland’s electricity need, said WWF Scotland.
The environmental group’s analysis based on data provided by WeatherEnergy found that for the month of June wind turbines in Scotland alone provided an 620,144MWh of electricity to the National Grid, while the total consumption was 1,891,536MWh.
This represents an increase of 120% ;D compared to that of June 2014, when wind energy provided 281,735MWh.
WWF Scotland’s director Lang Banks said: “While much of the attention may have been focused on the welcome summer sunshine, June also turned out to be an astonishing month for wind power in Scotland. Thanks to a combination of increased capacity and stronger winds, output from turbines more than doubled compared to the same period last year – supplying power equivalent to the electrical needs of 1.7 million homes.
“These figures show just how much wind power has gone from strength to strength. However, wind power in Scotland could and should be playing an even bigger role in helping to reducing climate emissions from the power sector. We therefore hope that the forthcoming Government onshore wind summit can find ways forward to help ensure this clean energy source can meet its true potential.”
Karen Robinson of WeatherEnergy said: “While good for generating power from the sun, the summer months often see a dip in the output from wind turbines. And, while output was certainly lower than the month of May, this June saw a massive jump in output when compared to last year. While the data confirms Scotland is knocking out of the park on wind power, it also confirms it’s no slouch when it comes to solar power too.”
US Offshore Wind Grows Behind the ScenesSustainableBusiness.com News
While it seems offshore wind in the US is barely budging, there's a lot happening behind the scenes. ;D
Besides the tiny project under construction in the Northeast, offshore wind projects in the pipeline total 15.7 gigawatts (GW)! 13 that are in advanced planning stages total 6 GW - enough power for 1.8 million homes - and 12 projects (over 3 GW) plan to be operating by 2020.
Offshore projects are moving ahead off the coasts of nine states. With 80% of US electricity demand coming from coastal states, offshore wind can play a crucial role in meeting our energy needs.
Deepwater's 30 MW project is the first to be under construction in the US:
Globally, there's now 9 GW of operating offshore wind farms, with another 4 GW coming online next year. In fact, offshore wind is expected to drive much of the industry's growth going forward.
Turbines are getting bigger and bigger, with the largest ones at 6 MW and 8 MW (typical turbines on land are 1.9 MW). To give you an idea of how large they are, the average offshore turbine at 3.4 MW is 279-feet tall and the blades are 377-feet in diameter.
Siemens, which leads on manufacturing offshore turbines, recently received a $1.2 billion order for 91 of its 6 MW turbines for Race Bank farm in the UK, and another order for 67 turbines for the Veja Mate Offshore Project in the German North Sea. The company is the favored supplier for a $2.9 billion order (171, 7 MW turbines) if the Hornsea Project One - the largest in the world - goes forward. Dong Energy is the developer for all these projects.
Offshore wind is expected to reach 30 GW in Europe by 2020 - 45% compound annual growth, according to Bloomberg New Energy Finance. The has 8 GW installed right now (http://www.sustainablebusiness.com/index.cfm/go/news.display/id/26180EU).

Check out this time lapse video. Watching the clouds go by is as much fun as watching the people!
Early this morning, thousands of knee-high pinwheels creating the outline of a wind turbine popped up on the National Mall in front of the U.S. Capitol!
The pinwheels were a celebration of an exciting announcement – that Procter & Ga mble has bought enough wind energy to make some of the best-known consumer products in America with 100% wind power.
An EDF Renewable Energy wind project in Muenster, Texas will generate as much electricity as used by the company’s factories in Ohio, Missouri, Louisiana, Kansas, and Ontario to produce Tide, Downey, Dawn, Cascade, and Febreze.
Those products sold nationwide will now carry the words “made with 100% wind power,” helping us get the word out that the clean energy revolution is here, and it’s being made in America. (http://www.pic4ever.com/images/8.gif)
Vermont Developer details plans for what would be state’s largest wind farm
Oct. 27, 2015, 4:58 pm by Mike Faher
GRAFTON – A developer is proposing Vermont’s largest, most-powerful wind turbine site – 28 turbines churning out nearly 97 megawatts – on a ridge in the towns of Windham and Grafton, according to new plans released Monday.
With that scale would come sizable economic benefits, as developer Iberdrola Renewables estimates $285,000 in annual tax revenue for Grafton and $715,000 for Windham – more than than that town’s entire budget. Also, the project might pump another $700,000 into the state education fund each year.
Those numbers could change, as could the proposed project’s final layout: An Iberdrola administrator expects that residents in both towns might vote on a final proposal in late 2016.
“It’s important for us to win a successful vote in Grafton and Windham in order to move forward,” Iberdrola spokesman Paul Copleman said, adding, “that’s what we will do here – honor the vote.”
But after Copleman and other executives faced many questions at a packed meeting at Grafton Elementary on Monday night, it’s not clear how those votes will go.
“There was a disconnect between what Iberdrola wanted us to know about benefits to the towns and what the very real concerns of the towns are,” said Mary Boyer, Windham Selectboard chairwoman.
Administrators at Iberdrola and New Hampshire-based Meadowsend Timberlands Ltd. first disclosed in 2012 that they were interested in studying wind resources at Stiles Brook Forest, a 5,000-acre tract that lies mostly in Windham and Grafton. Meadowsend owns and works that land, and the company has put forth environmental and economic reasons for pursuing wind turbines.
On a website set up to promote the project – www.stilesbrookforest.com – company administrators say Windham County’s first commercial turbine development “would help support (Meadowsend’s) ownership objectives for this piece of land by providing some stability to help keep it as working forestland in this time of climate change and volatile economics.”
Opponents are concerned about the project’s aesthetic and environmental impacts: In Grafton, a nonprofit called Grafton Woodlands Group has set up a Main Street storefront in opposition to large-scale wind turbines.
The project also has spurred consistent objections from Windham, where the town plan bans such turbines. Windham officials have traveled to Montpelier to testify about wind-siting and permitting issues.
Though Windham officials opposed installation of meteorological-testing towers at Stiles Brook, the state Public Service Board OK’d them, and the towers began functioning in April 2013. In September, the Public Service Board granted Iberdrola’s request to continue using those towers for another two years.
Iberdrola’s schedule still calls for turbine construction in 2019 “if favorable permitting decisions are obtained.” The biggest hurdle will be a state certificate of public good, and Iberdrola – doing business for this project as Atlantic Wind LLC – has not yet filed that application.
“We are still in the early stages of development,” said Jenny Briot, a senior business developer with Iberdrola.
The company is far enough along, though, to show for the first time a preliminary, proposed layout for the Stiles Brook turbines. They would sprawl across the parcel, with some clustered around an existing power-line right of way and others standing farther out, near the borders of Meadowsend property.
At their closest, the turbines would stand within about a mile of residences, Iberdrola estimates. But the company could not yet say how many people would be living that close.
Plans call for 20 turbines in Windham and another eight in Grafton. Each would be a 3.45 megawatt turbine standing 287 feet from the base to the top of the tower; with a blade extended in a straight-upright position, its tip would reach 492 feet above the ground.
The Stiles Brook wind development would be, by far, the biggest in Vermont. Among facilities already in operation, the next-biggest is Kingdom Community Wind in Lowell, with 21 turbines capable of producing 63 megawatts of power.
Stiles Brook’s turbines also would be, individually, the most-powerful in Vermont. Copleman said that’s a function of evolving design. “As turbines have gotten more efficient and cost-effective, they’ve been able to take advantage of more wind,” he said.
In addition to unveiling their first official design on Monday, Iberdrola administrators also estimated that the company would pay a total of $1 million in annual property taxes to the two towns. This number, after it is set in the form of a final offer, would not fluctuate from year to year, Briot said.
“It’s not based on production,” she said. “It’s based on installed megawatts.”
State education taxes are calculated differently for wind installations: The state reaps $0.003 per kilowatt hour of energy produced. Iberdrola officials estimate that the state could collect $700,000 per year from Stiles Brook, “and likely more.”
That would no doubt be welcome revenue for the cash-strapped state, but it’s not going to drive down anyone’s property taxes noticeably. A state Department of Taxes official on hand Monday night said that, in the context of the state’s education fund, the impact of Stiles Brook “would not be measurable in any significant way.”
There were roughly 150 people at Monday’s meeting. And, while some residents asked about Iberdrola’s financial figures, others reiterated concerns about impacts on health, property values and aesthetics.
Michael Clayton, a permitting manager for Iberdrola Renewables, displayed early tests showing that visibility of the Stiles Brook turbines would be “limited” in much of Grafton. Several of those in attendance questioned that conclusion, including Liisa Kissel, a Grafton Woodlands Group director.
“I was very disappointed in the visual simulations,” Kissel said after the meeting. “All of the photos were taken from low-lying places. Most of us live a little higher.” Added Boyer: “Our simulations don’t look like theirs.”
Clayton said Iberdrola is working on more such simulations and will disclose those at meetings planned for early 2016.
Kissel also was not impressed by Iberdrola’s tax-revenue projections. She believes that, even if tax rates decline, “that’s then counteracted by the loss of property value.”
Other issues raised at Monday’s forum included:
• In response to concerns about flooding, Iberdrola officials said the project will introduce a relatively small amount of new, impervious surfaces to Stiles Brook. “Very typically, it’s two acres or less per turbine,” Copleman said.
• When Kissel mentioned recent reports showing a lack of appetite among Vermont utilities for more wind-generated power, Copleman said the market could be different in 2019. “We think that, broadly, there’s an interest in renewable energy here in Vermont,” he said.
• Briot said the life expectancy of a wind turbine is 25 years. If Iberdrola builds at Stiles Brook, the company will have to create a state-regulated decommissioning fund to cover eventual dismantlement of the project, she added.
• There were several questions about noise, light and possible health impacts from turbines. Both during and after the meeting, Copleman responded by citing Vermont’s permitting process and Iberdrola’s track record.
“We can point to thousands of landowners that we lease land from and many more neighbors at our projects across the country where there is no problem,” Copleman said. “The scientific evidence does not link turbines to human health (problems).”
Iberdrola planned to hold another community meeting on the Stiles Brook project Tuesday at Windham Meeting House.
Beyond that, Briot pledged to continue to communicate with local residents. “As we have information and results from our studies, we will share them with you,” she said.
Agelbert NOTE: Many NIMBY whiners weighed in. One of the best comments to address the lack of logic among the whiners is the following one. Unfortunately, the idiots claimed, incredibly, that there is "no evidence" that wind turbines help reduce climate change impact. HELLO? What part of burning LESS fossil fuels means LESS climate change damage do these biosphere math challenged morons not understand? (http://www.pic4ever.com/images/gen152.gif)
At any rate, it's nice to know there are some Vermonters that get it. 8)
October 28, 2015 at 10:08 am
With all due respect to the commenters, I’m appalled by some of the gaps in rhetoric, employed by anti-winders, surrounding wind energy. Have we forgotten about climate change? This year it is projected that the world will lose another 15% of its coral reefs. Have already lost 30%. Meanwhile, entire mountain tops are being removed for coal mining.
The United States is so far behind on climate change, as is the world. If Vermont can’t be seen to support renewables how do we have a chance at all? I want to pass this planet on to my children in a state that is not mired in the chaos caused by unabated climate change. Others don’t want to have to look at a wind turbine.
I ask these people what will be more difficult. Looking at a wind turbine by now. Or looking into the eyes of the future generations and telling them that your obstructionism helped prevent Vermont from leaving the country against the impending global calamity that could reck most all ecology as we know it and irrevocably alter the way we live in Vermont and throughout the world . All energy comes from somewhere, it’s a sad state of affairs when people suddenly start caring about energy issues only when the effects of them appear in their backyard.
Energy issues affect us all and wind is an effective renewable that can lead us away from a path of unknown chaos, death and destruction. Climate change is the biggest threat facing our planet today. We need to act before it’s too late and remember that our homes are but a small part in a global world under threat. Don’t forget climate change. It’s real and it needs to be addressed now.

Mexico Planning $46 Billion Coast-to-Coast Wind Energy Push :o ;D
October 21, 2015
By Vanessa Dezem Adam Williams, Bloomberg
Mexico is planning to quadruple its wind power capacity as part of President Enrique Pena Nieto’s effort to transform the country’s energy industry.
The country expects to have about 10 GW of turbines in operation within three years spread across almost every region, up from 2.5 GW in 2014, part of a government plan to add 20 GW of clean energy by 2030, according to Mexico’s Wind Energy Association.
A total of 22 GW of wind power will be added over the next 25 years, requiring $46 billion in investment. The wind push is due to two converging trends: Mexico’s historic shift from a state-controlled energy monopoly, and its efforts to transform a grid that relies on fossil fuels for three-fourths of the nation’s electricity.
"We’re already a new country," Alejandro Peraza, general director of the energy regulator CRE, said in an interview in Mexico City. "Mexico is getting cleaner."
Mexico is Latin America’s largest crude producer and the world’s No. 10 producer of greenhouse-gas emissions. It was the first developing country to submit its plan to reduce carbon emissions before a United Nations conference in Paris in December, where almost 200 countries are expected to sign a deal to fight global warming.
Mexico pledged to reduce 22 percent of its greenhouse gas emissions by 2030. Wider use of renewable energy will reduce fossil-fuel based power generation to 45 percent.
"There is a clear national policy on climate change taking place,” Peraza said. “We are going in the direction of a low carbon economy."
Mexico’s economy will expand 2.4 percent this year, according to a Bloomberg News survey. The government expects energy demand to increase 4 percent annually over the next decade.
That growth will be fueled by the shift toward renewables, which will jump to 51 percent of total installed capacity by 2040, from 14 percent now, according to New Energy Finance. Most of that will come from wind, in part because import taxes drive up costs for solar power.
"Investors are starting to line up their horses," Lilian Alves, a New Energy Finance analyst in Sao Paulo, said.
To facilitate that transition, the government plans to hold annual energy auctions, with the first set for March. Power producers will receive certificates for every MWh of clean energy they generate, and will sell 20-year certificates through the auctions to large electricity users.
Large consumers must get 5 percent of their power from clean sources by 2018. The government also set a mandate in 2012 to get 35 percent of the country’s energy from non-fossil fuel sources by 2024, up from 21 percent now.
Those who don’t meet the mandate may be fined as much as $200 per MWh used, according to Peraza. Large industrial users may be required to buy clean-power certificates on the spot market.
Power companies are keen to jump into Mexico’s clean-energy market as soon as new rules for the auctions and certificates are finalized, according to Adrian Escofet, president of Mexico’s Wind Energy Association. Those policies are expected to be issued this month.
Gauss Energia, a Mexico City-based company that owns Mexico’s largest solar farm, is planning to register 100 MW of power projects for the March auction.
"I am optimistic," Chief Executive Officer Hector Olea said. "The certificates can’t be included in project finance papers now, as we don’t know their prices."
New government policies may not be enough to stimulate renewable energy in the short term, according to Luis Alberto Salomon Arguedas, clean energy specialist at International Finance Corp.
"Developers are waiting for more benefits, such as possible tax cuts for renewable energy or different ceiling prices for each energy source," Arguedas said. "If the game rules don’t change a lot, I think the government’s target is going to be difficult to be reached."
“This is an important moment to prompt wind-energy development,” in Mexico, said Angelica Ruiz Celis, Vestas Wind Systems A/S’s general manager for the country, where the biggest turbine supplier has 1 GW of capacity installed or under construction. "Mexico is a key market for Vestas."

Wind Power Now Cheaper Than Natural Gas for Xcel, CEO Says (http://www.pic4ever.com/images/za4.gif)
October 27, 2015
By Alex Nussbaum and Chris Martin, Bloomberg
Xcel Energy Inc., the biggest U.S. provider of wind power, expects long-term contracts for the technology to beat the cost of natural gas, another sign of the rapid transformation of the power market.
Xcel, the Minneapolis-based utility that serves eight states, is receiving bids for 20-year power purchase agreements at about $25 a MWh for wind energy, Chief Executive Officer Ben Fowke said in an interview Friday at Bloomberg News headquarters in New York.
While gas prices are close to historic lows, he doesn’t see them remaining there forever, and Xcel expects prices for electricity from the fossil fuel to be closer to $32 a MWh over the same period.
“When we’re buying wind at $25, it’s a hedge against natural gas," Fowke said. On some of the windiest days, the company’s farms supply as much as 60 percent of the utility’s power. “Wind is becoming pretty close to parity.”
Fowke has plans to add 1,600 MW of wind energy over the next 15 years or so, partly to replace output from two coal-fired units that are being retired at Excel’s Becker, Minnesota, plant. He also expects to exceed requirements in its largest states, Minnesota and Colorado, to get 30 percent of Xcel’s power from renewable resources.
“We have a plan to add significant amounts of wind to our system,” Fowke said, including about 800 MW by 2020. “We’re going to be able to retire coal plants earlier than we expected. It’s going to help us reduce our carbon footprint 60 percent by 2030” in the upper Midwest.
Xcel fell 1.9 percent to $36.44 at the close in New York on Oct. 23. The shares have gained 11 percent in the past year.

Renewables at the South Pole
Powering Mawson Station, Antarctica, with Wind
Mawson Station, located on an isolated outcrop of rock at the edge of the Antarctic plateau, is the oldest surviving, continuously operated research station south of the Antarctic Circle. It’s also the most remote of the three main Antarctic stations operated by the Australian Antarctic Division (AAD). Ongoing scientific research at the station includes middle and upper atmosphere physics, cosmic ray physics, geomagnetism, seismology, biology, meteorology, climate change studies, medicine, and automated upper atmospheric sciences. Two unique features make this station an ideal place to incorporate renewables for electricity generation. First, its remote location makes reliable delivery of diesel fuel difficult. Second, the wind resource in and around Mawson is outstanding. In 2002 and 2003, the AAD built two wind turbines at Mawson station, serving on average twenty researchers. Before installation began, the AAD completed an environmental impact assessment to ensure that the benefits of adding wind turbines outweighed potential negative ramifications including impacts on wildlife and the viewshed.
Mawson’s remote location and cold climate led to several challenges while preparing for and installing the two Enercon 300 kW wind turbines. The installation required a 100-ton crane, which called for the provision of a larger than typical icebreaking ship. Once the turbine components reached Antarctica, bridges at the station had to be strengthened to bear the weight of the vehicles transporting the turbines. Mawson station’s current electricity system includes 550 kW of diesel generator capacity, along with the 600 kW of total installed wind capacity. These resources are used to meet a load that peaks at 450 kW. Over the course of one year, approximately half of the electricity used at Mawson station comes from the wind turbines. The AAD website provides additional information about how this hybrid wind-diesel system is operated.
Interestingly, Mawson station’s electrical loads go beyond thermal comfort, lighting, and plug-loads. The station also includes some luxuries for residents, such as a spa and a sauna, which require relatively large amounts of electricity compared to other day-to-day uses. In order to maximize fuel savings, the AAD worked to educate people about using these amenities only when wind energy is readily available, rather than at times of low wind when the diesel generators provide the majority of the electricity.
The wind turbines created an additional impact on Mawson’s heating supply that’s of note for other remote microgrids with large heating requirements. Before adding wind to the system, two diesel generators powered the Mawson station and extra heat from these generators heated many of the station’s buildings. With the addition of wind, just one diesel generator runs for most of the year. This slashes the diesel requirement, but it also removes the extra heat source from the now rarely used second generator. In response, the AAD added an electric boiler to the system in tandem with the wind turbines. With any extra power available from the wind turbines, the electric boiler pre-heats water to heat buildings. The boiler is also connected to Mawson’s system with a smart inverter, which provides voltage and frequency support to the microgrid. The result is similar to having additional spinning reserves, since the boiler can ramp its output up or down quickly when there is a shift in available wind. (http://www.createaforum.com/gallery/renewablerevolution/3-080515182559.png)
In 2014 alone, the wind turbines generated enough electricity to reduce Mawson’s diesel consumption by 288,000 liters, directly saving the AAD $263,000 in fuel costs ;D.
The AAD also gained greater flexibility in scheduling resupply ships; instead of requiring a shipment of diesel fuel at least once per year to meet the station’s needs, the AAD can now send a refueling shipment every other year (http://www.pic4ever.com/images/8.gif).
The success seen at Mawson Station is already spreading, and other nations with operations in Antarctica have incorporated renewable resources for electricity generation. Furthermore, the now 10-year old wind turbines are still operating at high levels of efficiency—even in the tough winter climate.

Texas Wind Farms Generate So Much Power Utilities Are Giving Electricity Away for Free (http://www.createaforum.com/gallery/renewablerevolution/3-200714183515.bmp)Lorraine Chow | November 10, 2015 12:38 pm
Wind makes up 10 percent of the electricity used in Texas. Photo credit: Shutterstock
Did you know that Texas, a state known for its lucrative oil and gas industry, is actually the largest wind power producer in the country? It now appears that wind farms are cranking out so much excess energy, that utilities are giving this renewable energy source to customers for free.
The New York Times reports that thousands of customers in the state are paying zero for their electricity needs between 9 p.m. and 6 a.m., saving $40 or $50 a month during the peak summer season.
The Times writes:
“TXU’s free overnight plan, which is coupled with slightly higher daytime rates, is one of dozens that have been offered by more than 50 retail electricity companies in Texas over the last three years with a simple goal: for customers to turn down the dials when wholesale prices are highest and turn them back up when prices are lowest.”
The newspaper describes, for instance, that Dallas residents are waiting until after 9 p.m. to run the washing machine and dishwasher so it costs them nothing (http://cliparts.co/cliparts/Big/Egq/BigEgqBMT.png). One resident even unplugs her appliances when she goes to work in the morning then plugs them back in at 9 p.m. (http://www.createaforum.com/gallery/renewablerevolution/3-080515182559.png) ;D
Here’s a commercial from utility company boasting its free electricity at night. ;D
It might seem that this set-up is rife for wasting energy (such as cranking up the thermostat past 9 p.m.), but as the Times reports, the scheme actually saves the utility company money in the long term, since shifting use from peak hours means lower wholesale prices, and possibly avoiding the costs of building more power plants.
“That is a proverbial win-win for the utility and the customer,” Omar Siddiqui, director of energy efficiency at the Electric Power Research Institute, told the publication.
EcoWatch mentioned previously that the Lone Star state’s top power source is gas (50 percent) followed by coal (32 percent). However, in 2014, wind shot up to 10 percent of the electricity used in the grid, up from 6.2 percent in 2009. Wind powers approximately 3.3 million Texas homes.
According to the U.S. Energy Information Administration (EIA), “the growth in wind generation is a result of new wind plants coming online and grid expansions that have allowed more wind power to flow through the system to consumers.”
Texas also has the largest deregulated electricity market in the country, making it easier for energy companies to create new incentives and offer more economical choices for customers.
As Scott Burns, senior director for innovation at Reliant Energy, told the Times: “You can be green and make green.”
WInd energy output is setting new records.
Wind records fall again in November as race to the top continues
November 19, 2015
And we thought October was impressive; turns out things have been even better this month. ;D
Grid operators in Texas (ERCOT) and the Midwest (MISO) continued jockeying for the wind output record in November, with ERCOT coming out in front this time. It hit a record high of 12,641 megawatts (MW) on November 16, which bested MISO’s 12,383 MW from October 28, for the highest output on a U.S. power system.
Other grid operators hit high water-marks in recent weeks as well.
PJM, which operates the power system for the Mid-Atlantic and Great Lakes states, reached a record output of 5,648 MW on November 1, while the Southwest Power Pool (SPP) cleared 9,000 MW on November 15.
Wind has reliably contributed a large share of total electricity supply across the U.S. in recent weeks:
•Just this morning, MISO set a new hourly wind output record, reaching an hourly average of 12,295 MW, exceeding the previous mark of 12,194 MW set on October 28. While minute-by-minute wind output data from MISO is not yet available, it is possible that at some point this morning MISO wind energy output exceeded its previous instantaneous record of 12,383 MW.
•For a combined nine hours on November 10 and 11, wind was the number one electricity generation source in SPP, averaging about 35 percent of the total energy mix. Impressively, the output averaged over this period neared SPP’s instantaneous output record of 36.8 percent, further proof that wind can contribute a significant amount to the electricity mix for a sustained period of time.
•PJM, one of the largest power systems in the world, obtained more than 9 percent of its electricity from wind when it set its wind record on November 1.
•Earlier this year, ERCOT obtained more than 40 percent of its electricity from wind
•The main Colorado power system has previously gone higher than 60 percent.
As we previously explained, these record outputs provide concrete evidence that wind can reliably constitute a significant portion of our electricity mix. As Robbie Searcy of ERCOT notes, “We’ve really gotten very effective at integrating a large amount of wind into the power grid.”
The record outputs we’ve seen throughout the fall are the result of a broader “wind rush.” New wind project development, technological advances, and long-needed grid upgrades are making low-cost wind energy available to new customers across the country, resulting in a more reliable, affordable, and balanced energy mix.
This is a trend we expect to continue in the coming years, and it will help businesses and consumers keep their lights on and extra money in their pockets.

» Wärtsilä Ship Design to supply design for offshore vessel conversion
By John Stansfield, November 25, 2015, Vessels
Dutch ship owner C-Bed has contracted Wärtsilä Ship Design to supply the design for rebuilding its Seismic Survey Vessel, the ‘Viking II’, for use as a hotel vessel. When completed, the rebuilt ship will be used to accommodate and transfer service personnel working on offshore wind farms. The rebuild project is being carried out at the Fayard AS shipyard in Denmark and is expected to be completed during the first quarter of 2016. The contract with Wärtsilä was signed in September.
Wärtsilä Ship Design to supply design for offshore vessel conversion
Wärtsilä provided the original designs for the ‘Viking II’ earlier known as ‘Veritas Viking II’, which was delivered in 1999 to the original owners, Eidesvik of Norway.
After the conversion, the vessel will have accommodation and hotel facilities for 125 people and will feature a heave compensated gangway. The converted vessel will fulfil the requirements for Special Purpose Ships and will in the future be named ‘Wind Innovation’.
“This is a fast delivery project and it was essential that our naval architects could respond to the owner’s needs quickly. This we are able to achieve and our design will result in a vessel capable of operating efficiently in challenging sea and weather conditions with a high level of passenger comfort,” says Ove H. Wilhelmsen, Managing Director of Wärtsilä Ship Design Norway.
Wärtsilä has considerable experience in producing designs for the offshore wind turbine market, both for service vessels as well as for installation applications. Conversion projects are becoming of increasing interest for owners since there is a current over-supply of ships in many of the offshore application markets.

Philips Buys Wind Energy For All North American OperationsSustainableBusiness.com News
Philips, the inventor of the compact flourescent bulb, and a long-time leader on sustainable business practices, will power all North America operations with wind by the end of 2016. ;D
It is buying the output from Hidalgo Wind Farm in McCook, Texas over 15 years to power 133 locations. The 250 megawatt project is under construction by EDF Renewables.
"Our power purchase agreement will allow a brand new wind farm to be built in Texas. (http://www.createaforum.com/gallery/renewablerevolution/3-200714191258.bmp) Moreover, by offsetting our North American operations with renewable energy, we will reduce Philips' global carbon footprint by 8.6%, support the local economy and positively impact our bottom line, demonstrating the private sector can benefit from and help drive clean energy," says Brent Shafer, CEO of Philips North America.
Philips' goal is to be carbon neutral by 2020. It's a founding member of RE100, an effort to convince 100 of the world's largest businesses to run completely on renewable energy by 2020. Worldwide, Philips gets 55% of electricity from renewables, growing from just 8% six years ago.
Last year, Philips introduced "lighting as a service" with Washington DC as its first customer. It ranks at the top of all companies for sustainable practices by CDP and in the top 10 electronics companies by Greenpeace.
Trump loses UK lawsuit! (http://www.pic4ever.com/images/za4.gif) 100 megawatt offshore wind farm will now go forward. (http://www.createaforum.com/gallery/renewablerevolution/3-200714191258.bmp)
12/17/2015 04:50 PM
Climate denier Donald Trump (who said he wouldn't bother attending the Paris Climate Summit) may be leading in Republican polls, but he's not doing so well across the Atlantic Ocean.
Since 2013, he's been trying to block an offshore wind farm in Scotland - because he doesn't like the view from his new golf course and resort located there.
After multiple appeals, he failed to block the wind farm in Scotland courts so he took it to the UK Supreme Court ... and now, they too (unanimously (http://www.pic4ever.com/images/balloons.gif)) rejected his argument.
The 100 megawatt offshore wind farm will now go forward placing 11 wind turbines two miles off the coast, and powering 86,000 homes - half the population of Aberdeen.
Also planned is the European Offshore Wind Deployment Centre, an offshore wind-testing center where developers can test technologies before deploying them, cutting capital costs and risks. It would establish Scotland as a hub for offshore development in Europe.
"History will judge those involved unfavorably and the outcome demonstrates the foolish, small-minded and parochial mentality which dominates the current Scottish government's dangerous experiment with wind energy," says the Trump Organization in a statement. Trump "will evaluate the court's decision and continue to fight this proposal on every possible front."
The golf course should never have been built in the first place - it destroyed Scotland's ancient dunes and wildlife habitat, while permanently disrupting the lives of the people who live there. Trump strong-armed the government and local communities to get it through as described in the compelling documentary, You've Been Trumped.
This would be the view: (at link below)
Scotland offshore wind
He also fiercely fought an offshore wind farm off the coast of Ireland, which ended up being cancelled because of endangered species concerns.
And he's really up in arms because two massive offshore wind farms are also planned for the area, powering over 1 million homes, and helping the country meet its goal for 100% renewable electricity by 2020.
Trump says, "We will spend whatever monies are necessary to see to it that these huge and unsightly industrial wind turbines are never constructed." (http://www.freesmileys.org/smileys/smiley-devil19.gif)
Trump is a member of the "climate change is a hoax" camp, often pointing out that there's cold weather and snow. (http://www.pic4ever.com/images/p8.gif) (http://www.pic4ever.com/images/126fs2277341.gif)
TDI New England approved for $1.2 billion transmission project
Jan. 6, 2016, 3:34 pm by Mike Polhamus
The Public Service Board on Tuesday approved a $1.2 billion utility transmission project from Canada to Ludlow.
TDI New England plans to build a 1,000-megawatt transmission line under Lake Champlain that will feed the southern New England power grid.
The board said it issued a certificate of public good to TDI because the project diversifies energy sources, reduces greenhouse gas emissions, creates new jobs, generates tax revenue and potentially supplies cheaper energy.
The Montpelier-based Conservation Law Foundation agreed last year not to oppose the project after it was able to negotiate large payments from the utility for Lake Champlain cleanup.
“TDI New England did a good job of showing that large energy projects can meet high environmental standards,” said CLF Senior Attorney Sandra Levine. “There are a number of transmission projects in the region being evaluated and considered; this isn’t an endorsement of this project, it’s just a recognition that they did a lot of things right, and I think they have set in some ways a model for other projects.”
An instructive comparison can be made between this project and the Vermont Gas Systems natural gas pipeline proposed for Addison County, Levine said.
The pipeline has met steady opposition from AARP and landowners, she said, because Vermont Gas has done a poor job of evaluating the pipeline’s impacts and hasn’t been transparent enough with ratepayers and the board about costs.
“When you look at the two side by side, Vermont Gas is still facing problems with permitting, and the TDI project has received its permits,” she said.
The firm merely followed sound business practices, said TDI New England’s CEO Donald Jessome.
The project is being built not out of necessity, as is the case with some power projects, but rather for economic reasons, and as such “there’s no question we have a higher burden to the states we’re traversing to demonstrate public good,” Jessome said.
Early in the project’s development, the firm reached out to stakeholders, including environmental organizations, state regulatory bodies and others, Jessome said.
“We totally understand that in the development world we have to listen to all the stakeholders,” he said.
TDI plans to pay hundreds of millions of dollars toward environmental cleanup efforts over the project’s lifespan, and Jessome said “we see that as a cost of doing business.” Large portions of those monies were secured through negotiations with the Conservation Law Foundation.
The cable will run from the Canadian border to Ludlow, sunken for most of that length beneath Lake Champlain.
The so-called New England Clean Power Link is being built in response to renewable energy needs in New England states. Like Vermont, these states have aggressive renewable energy goals.
The cable will carry 1,000 megawatts, roughly the amount of power consumed by the entire state of Vermont. If it is constructed, Vermont will host the cable, and most of the electricity will be transmitted to southern New England. Vermont will have the option to purchase up to 200 megawatts from the cable.
The cable is expected to carry power from dams and wind turbines. (http://www.pic4ever.com/images/19.gif)
TDI has agreed to pay a minimum of $283.5 million over the 40-year lifespan of the project for Lake Champlain phosphorus cleanup, habitat restoration and recreational improvements — $121.5 million more than was originally proposed. Some of that money would also go to the state’s Clean Energy Fund.
TDI has also agreed to pay the state’s transmission utility, Vermont Electric Power Co. (VELCO), $136 million or $2.5 million annually over 40 years. That money is expected to be used to reduce electric rates, according to state officials.
TDI New England is a subsidiary of financial firm Blackstone Group, which manages more than $200 billion in assets. The firm anticipates permitting will take until mid-2016, with major construction beginning in 2018. If the New England Clean Energy Link moves forward, then the 1,000-megawatt transmission line is anticipated to be carrying power by 2019.

Salesforce Signs Second Major Renewable Energy Deal In As Many Months
Jan 27, 2016
David Labrador Writer / Editor
Last year set a record for renewable energy purchases by corporations with 3.44 GW, nearly tripling 2014’s total, and this year is already off to a fast start. The first out of the gate is cloud-computing company Salesforce, which announced a 12-year virtual power purchase agreement (VPPA) for 24 MW of wind power from a Texas wind farm on January 14. The Bay Area heavyweight is a founding corporate member of RMI’s Business Renewables Center (BRC).
The deal, concluded with BRC sponsor EDF Renewable Energy, is for a portion of the electricity generated by the 200-MW Salt Fork Wind Project in the Texas Panhandle. (http://www.createaforum.com/gallery/renewablerevolution/3-200714191258.bmp) Salesforce has operations in the region, and electricity from the wind farm will feed into the region’s grid, though not to Salesforce’s facilities directly. This is the essence of a VPPA, much like a subscription to a community solar garden in which a homeowner is credited for the electricity generated at a solar array elsewhere in the community. Salesforce’s Salt Fork deal is expected to provide 102,000 megawatt-hours of wind energy per year once it comes online in December 2016.
A Repeat Performance
When Salesforce announced its VPPA for 40 MW of wind power from a West Virginia wind farm in December, it entered the off-site renewable energy market for the first time. First-time entrants in fact proved a significant driving force for 2015’s record corporate numbers. Now Salesforce is back for more, which is exactly what the BRC works to achieve—to streamline and accelerate corporate renewable energy purchasing, including seeing more companies becoming first-time and repeat buyers. Stephen Abbott, a senior associate at RMI, says, “Salesforce committing to a second PPA after signing their first contract last December is an excellent example of how new companies can join the renewables club and build momentum quickly.”
Patrick Flynn, director of sustainability at Salesforce, says, “Having that experience with these two successful projects completed gives familiarity and confidence to all the parties involved,” including internal stakeholders. PPAs and, especially, VPPAs are complex deals that many corporations are not yet familiar with, which is why new entrants are important. Salesforce completed the deals with the help of transaction service provider Renewable Choice Energy, a founding sponsor of the BRC.
The BRC formed in 2014 and hit the ground running in early 2015 to accelerate corporate renewable energy procurement with the goal of adding 60 GW of off-site wind and solar capacity in 10–20 years. When the BRC publicly launched in early 2015, just a handful of companies had done deals and the goal seemed far off. Salesforce and others have totally changed the dynamic. Lily Donge, a principal with RMI’s electricity practice and leader of the BRC, says, “Salesforce has gone from zero to 60 with two rounds of PPAs in two months. This is exactly what the market needs to see—companies entering the market for the first time, and following up with yet an additional deal in two months.”
Towards 100-Percent Renewable Energy(http://www.createaforum.com/gallery/renewablerevolution/3-260116191529.png)
Salesforce’s Flynn says, “This is a doubling down on our renewable energy commitment.” The combined output of the VPPAs Salesforce signed for West Virginia and Texas power is expected to be 227,000 megawatt-hours per year, which is more electricity than Salesforce used during its 2015 fiscal year. This is important because Salesforce is not just a member of the BRC; it is also a member of the RE100, a forum where corporations make a pledge to transform to 100-percent renewable energy.
However, Salesforce can’t rest on its laurels just yet. Flynn explains, “By the time these projects come online and have been operating for a full year, we will have grown beyond that fiscal year 2015 footprint. We think we’re still going to have to look for more great projects—like both of these—and other ways to keep moving forward towards our RE100 goal.”
Making a Cleaner Cloud
More than 40 percent of Fortune 500 companies have clean energy or climate targets and the aim of BRC members like Salesforce is to help them move as quickly as they are. “Hopefully we can keep doing the sorts of projects that not only bring about additional renewable energy, but bring it about in a way, like this VPPA, that we can clear a path or provide a blueprint for other companies to follow,” says Flynn.
More than 1 GW of 2015’s corporate power purchases were by cloud-computing companies like Salesforce and other companies with huge data centers, such as Amazon. This trend makes sense to Flynn, who says, “Salesforce understands that it has an opportunity to define a cleaner cloud. Data centers power the Internet, and they consume a lot of electricity, so I think it’s a natural fit that cloud companies like ours try to find ways to innovate and bring about positive change.”
Bringing Everyone Into the Renewable Energy Space
And as BRC members, Salesforce, EDF Renewable Energy, and Renewable Choice Energy are truly helping others to create that cleaner cloud by sharing their hard-won knowledge. “The industry’s moving quickly,” says Flynn. “When we see other news come out, we’re excited about it. Regardless of what company did it, every step forward counts.”
Salesforce has an RE100 commitment to switch to 100-percent renewable energy and has pledged to achieve net-zero greenhouse gas emissions by 2050, and it is moving aggressively towards those goals. “If you can do that in a way that also provides a learning opportunity both for yourself and others, that’s something to feel really good about,” Flynn says, and it’s also the essence of the BRC. Flynn says, “Looking forward, we’ll want to share our thought process, what led us to the VPPA, why it was a great fit for us, and best practices that we’ve identified for getting deals like these accomplished with the other members of the BRC.”
World's first 1+GW offshore wind farm confirmed
Sami Grover (@samigrover)
Energy / Renewable Energy
February 4, 2016
When I moved from the United Kingdom to the United States in 2006, offshore wind just wasn't a thing in Britain. Now, the UK has more offshore wind capacity than all other countries combined.
That capacity is going to grow some more too.
Business Green reports that DONG Energy has announced it's moving ahead with Hornsea Project One, a project that's slated to be the largest offshore windfarm in the world, and the first with over 1GW of nameplate capacity. But that's not all. While Project One will be online by 2020, DONG also has rights to develop the imaginatively titled Project Two and Project Three at Hornsea, which together will bring an additional 3GW of capacity online.
Offshore wind is truly going mainstream, and this is using existing 7MW wind turbines. Some researchers are speculating, however, that we may soon have gigantic offshore turbines with up to 50MW of capacity each.
Something tells me that Hornsea Project One won't be the biggest farm for long. (http://www.pic4ever.com/images/128fs318181.gif)(http://www.desismileys.com/smileys/desismileys_0293.gif)
Dong Energy to Acquire Lease for Wind Project Off New Jersey CoastFebruary 10, 2016 by Bloomberg
By Joe Ryan
(Bloomberg) — Dong Energy A/S, the world’s largest offshore-wind developer, agreed to acquire a lease for a site off the coast of New Jersey with more than 1,000 megawatts of potential capacity, marking the company’s second push into U.S. waters.
Dong plans to take over the 160,480-acre lease from RES Americas Development Inc., the Fredericia, Denmark-based company said in a statement Tuesday. RES Americas won the lease in a November auction held by the U.S. Bureau of Ocean Energy Management, which must approve the transfer.
Dong is moving into an area where offshore wind has languished. The state’s Board of Public Utilities has rejected Fishermen’s Energy LLC’s proposal for a 25-megawatt pilot project, saying the power would be too expensive for consumers. Building a bigger facility and paying for construction itself will address that, according to Thomas Brostrom, Dong’s general manager of North America.
“We are looking at a large-scale project here,” he said in an interview Tuesday. “You have a lot of benefits from that.”
The New Jersey lease area is 10 nautical miles off shore, south of Atlantic City, with water depths of about 80 feet (24 meters). The conditions are similar to those Dong currently works with in North-Western Europe, the company said.
Last year Dong acquired a site south of Martha’s Vineyard, Massachusetts, in another deal with RES. Both projects would require state and federal permits. It will be at least four years before construction can begin, and it’s too early to estimate the cost of either project, Brostrom said.
Dong, which pioneered the world’s first offshore wind farm in 1991, has projects with more than 2,000 megawatts of capacity in operation and another 1,000 megawatts under construction. The company opened its first U.S. office last year in Boston and is scouting the East Coast for other locations to build, Brostrom said.

“To build an industry you need volume,” he said. “We see a lot of potential in the American market.” (http://www.freesmileys.org/emoticons/emoticon-object-062.gif)
Offshore Slump Has Norway’s Eidesvik Turning to Wind ;D

Eidesvik offshore service specialists ship
The prolonged slump in the offshore Offshore Slump Has Norway’s Eidesvik Turning to Windmarket has Norwegian offshore service specialists Eidesvik turning to offshore wind for work.
Eidesvik Offshore announced this week that it has entered into a service and support vessel with Siemens Wind Power, its first contract within offshore wind sector.
Under the agreement, Eidesvik’s vessel Acergy Viking has been chartered to Siemens for nine months as an accommodation and service vessel in German sector of the North Sea.
Eidesvik said for some time it has looked into offshore wind as a strategic business segment and now has secured the first contract in this segment.
The vessel will undertake a short mobilization, which includes installing an offshore gangway system, prior to the contract commencement in August.
“I am pleased with our organizations ability to adapt to a new marked and that we now will enter a new business segment with one of our existing Subsea vessels. The Acergy Viking has been in lay-up for a short period and we are glad that she will be out in operation again,” Eidesvik CEO Jan Fredrik Meling said in a statement.

NorSea Wins World’s First Floating Wind Farm Contract (http://www.createaforum.com/gallery/renewablerevolution/3-080515182559.png)
Published at 10:11AM - 19/02/16
NorSea wins world’s first floating wind farm contract from Statoil, as the Norwegian oil and gas major moves closer to yet another first.
The contract is for work on Statoil’s Hywind project, an offshore wind farm in UK waters that will be the world’s first to utilise floating turbines rather than fixed sub structures.
The method being pioneered by Statoil is hoped to reduce both the cost and construction time of offshore wind considerably.
NorSea Wins World’s First Floating Wind Farm Contract
NorSea’s contract covers the use of their Stordbase yard, located between Stavanger and Bergen. Statoil aims to utilise the yard as a pre-assembly point for the turbines before transportation to the British sector.
With a value of between US$ 6 – 8 million (NOK 50 – 70m), the contract is set to start at the beginning of March 2016.
(http://www.statoil.com/no/NewsAndMedia/News/2015/PublishingImages/03Nov_Hywind_468a.jpg)Statoil Hywind Wind Farm UK
NorSea Group CEO, ohn E. Stangeland said: ”NSG is very grateful and proud to have been awarded this crucial contract from Statoil.”
“We want to be a preferred supplier of integrated services to the supplier industry and wind farm owners in the offshore wind market. This contract will therefore be a key step in our strategy of offering cost-effective solutions to the renewable energy market,”
The 30 Mega Watt Hywind project, is an offshore wind farm, located approximately 16 miles (25km) offshore Peterhead, UK, and operated by Statoil.
Being hailed as a pilot project its main purpose is to test and demonstrate the effectiveness of new technologies, Statoil is developing within the offshore wind sector, most notably floating turbines.
Construction is set to take place during 2016 through 2017, with final commissioning taking place in 2017.

A Small Country Goes Big with Renewables: Denmark’s goal to be fossil fuel free
The small country of Denmark (pop. 5.6 million) is making a big commitment to renewables. In the early 1970s imported oil supplied 92 percent of Denmark’s energy. Today Denmark’s electric grid is over 40 percent renewably powered, and the country is aiming to reach 100 percent renewable electricity by 2035 and 100 percent renewable energy in all sectors by 2050. Denmark also plans to reduce its domestic greenhouse gas emissions by 40 percent by 2020 relative to 1990 levels–without the use of carbon credits—ten years ahead of the proposed EU target.
A Wind Power Pioneer
Denmark is fortunate to have extremely good wind speeds—averaging 7.6 meters per second (California’s Altamont Pass wind farm sees 5.3 to 7.1 m/s, and power output rises as the cube of windspeed). The country has a goal for windpower to supply 50 percent of electricity consumption by 2020, and it is well on its way. In 2015, wind power supplied 42 percent of domestic electricity consumption.
Denmark was the first country in the world to build massive offshore wind farms, installing a 5 MW wind farm two kilometers from the coastline in 1991. Since then the country has installed four other offshore wind farms bringing offshore wind capacity to 1,271 MW.
The country also has over 300 onshore wind turbines bringing total wind capacity as of January 1, 2016 to 5,070 MW. To reach its goal of 50 percent wind power by 2020, the country has an initiative to deploy an additional 1,000 MW of offshore and 500 more MW of nearshore wind turbines, as well as to replace old onshore wind turbines with new higher-capacity ones.
In order to avoid any potential local opposition to the onshore wind farm, the Danish government implemented various regulations to help with public acceptance. For example, residents are compensated if a property loses value due to wind turbines, the local community receives a payment per megawatt-hour of power generated, and at least 20 percent of the shares in a wind farm must be offered to local residents.
Denmark is also a great example of how energy consumption can be decoupled from economic growth. Over the past 30 years, the country’s energy consumption has remained relatively stable, while gross domestic product has doubled. “Our continued efforts on energy conservation have greatly reduced our electricity demand,” ;D according to Henning Parbo, Chief Economist for Energinet, the country’s electric and gas transmission system operator. “And Denmark is not characterized by high energy-intensive industry.”
In fact, Denmark is one of the most energy-efficient countries in the EU and the OECD, partly because many Danish companies have optimized their industrial processes, facilities, and equipment. Denmark’s goal is to reduce its final energy consumption by 7 percent in 2020 compared to 2010. The different energy sectors in Denmark—oil, electricity, natural gas, and district heating—are each assigned a share of energy savings to reach depending on their market share. The trade associations for those sectors then delegate responsibility for those savings to its member companies, also based on market share. The country also quadrupled new buildings’ thermal efficiency from 1977, and forbade oil- and gas-fired heating of new buildings from 2013.
Combined Heat and Power
Denmark is also a leader in combined heat and power (CHP). Twelve percent of all power in Denmark is generated from biomass and organic waste in CHP plants, and more than 80 percent of Danish district heating is cogenerated with electricity. Today, there are 670 decentralized CHP plants around the country. Most of the biomass being used in Denmark today is from straw and biodegradable waste, and 30 percent is imported from Eastern European countries and Canada in the form of wood pellets and wood chips. Biomass proponents claim that burning wood pellets is a carbon-neutral form of energy because the plants that are the source of biomass capture as much CO2 when growing as they emit when burned. However, many others believe harvesting wood for biomass is anything but carbon-neutral and threatens many diverse ecosystems throughout the world.
In December 2014, the Danish Ministry of Climate, Energy, and Building announced that only sustainably produced biomass would be purchased. The agreement includes requirements for the entire biomass supply chain and requires that forests that supply biomass for energy production be replanted. However, the debate continues, as some argue that planting is no guarantee of healthy maturation—about as much biomass belowground must also be protected in its volume and biodiversity, and although the biomass may be sustainably produced, the magnitude of the biomass material harvested may be unsustainable.
Denmark’s CHP plants, in combination with the wind turbines, make Denmark one of the countries with the highest percentage of distributed generation in the world. In 1990, the country had 15 central power plants. It now has 20 central power stations (4,200 MW), 45 electric boilers (550 MW), 5,300 wind turbines (5,070 MW), and 94,000 solar PV panels (785 MW), in addition to the 670 local combined heat and power plants (2,300 MW).
While the variability of wind power can be challenging, one advantage Denmark has is its proximity to other countries to which it can export wind power. When Denmark has an excess of wind power, as happened last July when the country’s wind turbines produced 140 percent of the electricity demand, it exports electricity to Sweden, Norway, and Germany. Sweden and Norway import the electricity to save water in their hydro reservoirs, and use their hydropower during periods of low wind. Germany uses German windpower to save coal, though Germany’s own renewables are so robust that with their legal (and economically rational) dispatch priority, they often limit Denmark’s ability to export to Germany. Denmark is also looking into establishing new connections to farther countries such as Holland and England.
Denmark is hoping to build a smart grid, and embarked on a full-scale smart grid pilot project in 2005, by reorganizing its grid in a cellular architecture. The Cell Controller Pilot Project (CCPP), which lasted for seven years, used advanced computers to jointly control wind turbines, CHP plants, and other distributed generation sources in a 1,000 square kilometer region, making them operate as a single integrated virtual power plant that can intelligently ramp production up or down depending on wind conditions and power consumption. This not only helps with grid reliability, but also provides ancillary services such as power balancing, import and export of power, and voltage control. A study conducted by Energinet showed that implementing a smart grid would provide gross socioeconomic benefits of $1.2 billion.
Most importantly, Danish grid operators, who 15 years ago would have considered it impossible to run the grid stably with three-fifths renewable supply, now achieve this routinely. They have become among the world’s most adept at integrating diverse, distributed, often variable, renewable resources. As a result, Danish electricity supply is the most reliable in Europe, slightly ahead of Germany’s, and about ten times more reliable than U.S. electricity supply. ;D
Being fossil fuel free by 2050 means a big change in transportation. Yet Denmark has already made great strides. To discourage gasoline consumption, Denmark has a 180 percent tax on new cars, waived if one buys an electric car; a 95 percent surtax on cars weighing over two tonnes; and an annual tax on cars’ inefficiency. There is also free parking for EVs in all cities. It is estimated there are more than 4 million bicycles in Denmark and more than 10,000 kilometers of separated bike paths and bike lanes. And one-third of all commutes to work and school are done by bicycle.
A Fossil-Fuel-Free Future (http://www.createaforum.com/gallery/renewablerevolution/3-260116192120.png)
In its 2014 report, the Danish Energy Agency laid out four scenarios on how to be fossil fuel free by 2050:
Wind scenario: primarily wind, solar PV, and CHP deployment, including massive electrification of the heat and transport sectors
Biomass scenario: CHP for electricity and district heating.
Bio+ scenario: Replacing coal, oil, and natural gas with bioenergy. Wind energy remains at 2020 level (50 percent of electricity).
Hydrogen scenario: Highest wind deployment of any scenario along with hydrogen production.
The country does face challenges ahead. “The continued governmental support around Europe to renewable energy with zero marginal costs drives conventional units out of the market and will make the pricing of electricity a strange business,” Parbo told RMI. “This also means that the ability to supply enough electricity in periods with no wind and no solar production will become the main future challenge.”
But the main conclusion of the Danish Energy Agency’s report is that it is technically feasible for the Danish energy system to be 100 percent fossil fuel free. And it’s well on its way. (http://www.pic4ever.com/images/maniac.gif) (http://www.freesmileys.org/emoticons/emoticon-object-081.gif)
U.S. Offshore Wind Cost May Drop 55% as Builders Gain Experience
March 15, 2016 by Bloomberg

By Joe Ryan
(Bloomberg) — The cost of building wind farms off the U.S. coast may decline as much as 55 percent within 13 years, letting developers offer clean power at rates competitive with market prices, according to a study released Tuesday by the University of Delaware.
If developers commit to a series of large projects, installing about 2,000 megawatts of capacity between 2020 and 2030 off the Massachusetts coast, they will gradually drive down costs as they gain experience, install transmission lines, upgrade infrastructure and utilize increasingly efficient components, the study found.
While offshore wind has thrived in Europe, the high costs of erecting turbines at sea has sunk most U.S. projects (http://www.createaforum.com/gallery/renewablerevolution/3-200714183312.bmp). Developers previously proposed wind farms off the East Coast with rates as high as 24 cents a kilowatt hour, more than double the market rate. The University of Delaware found that they could cut those costs to 12.8 cents a kilowatt-hour by 2026, and to 10.8 cents by 2029, when the industry may have installed as much as 2,000 megawatts.
The key to making offshore wind economical “is making a firm commitment to scale so the market can do its work,” Willett Kempton, a professor in the University of Delaware’s School of Marine Science and an author of the study, said in a statement.
The study, funded by the university’s Wind Power Program, used data from offshore wind developers that are looking at potential sites along the East Coast.
The study comes as Deepwater Wind LLC is building the first wind farm in the U.S., off the coast of Rhode Island. It’s scheduled to begin operations by the end of the year, and National Grid Plc has agreed to pay as much as 24.4 cents a kilowatts hour for the power.
Massachusetts lawmakers are considering legislation to encourage developers to build additional projects in the Atlantic near Martha’s Vineyard. Three developers — Deepwater, Dong Energy A/S and Offshore MW LLC — have leases from the federal government to build in the area.

U.S. Wind Energy Blew Away Records in 2015
U.S. wind energy output hit record levels last year, producing nearly 5 percent of the nation’s electricity, according to a new report from the American Wind Energy Association (AWEA).
Employment in the sector also rose 20 percent in 2015, with 88,000 workers now employed in wind energy across the U.S. More than 8,500 megawatts of wind capacity was installed last year, almost doubling the total from the year before
Texas continues to lead the nation in wind power, but other states are closing the gap with large projects in the works.
AWEA expects more than 14,000 megawatts of new wind capacity this year, with support from incentives like federal tax credits and pollution cutting regulations.
Colorado wind power rising; 1,880 turbines and Xcel, Vestas plan more
Colorado set national records with 54 percent of Xcel's electricity over two 24-hour periods generated by wind.

Wind power can produce as much as 67% of electricity in Colorado
BRIGHTON — Colorado wind power is rising with 1,880 huge turbines erected across the prairie, twisting white blades as long as soccer fields, a cleaner source of energy replacing fossil fuels.
It has reached the point where the wind turbines generated 67 percent of Xcel Energy's Colorado-made electricity one morning in November and 54 percent for two 24-hour periods in October — feats unmatched around the nation, industry officials said Tuesday.
Falling costs, a state mandate, a federal subsidy and sheer momentum are driving the shift to renewable energy.
The proliferation of turbines here — doubling the number in 2009 — reflects a takeoff of wind power nationally that has cut carbon dioxide emissions by 132 million tons, American Wind Energy Association research director Michael Goggin said.
(Picture at link)
Governor Hickenlooper hails rise of wind power at Vestas plant on April 12, 2016. (Bruce Finley, The Denver Post)
"That's the equivalent of taking 28 million cars off the road [img with=50]http://www.clipartbest.com/cliparts/xig/ojx/xigojx6KT.png[/img], and this is going to help Colorado comply with the Clean Power Plan," Goggin said.[/size][/b][/color]
Shifting from coal and gas to wind power "will help bring the United States into compliance with international climate change commitments. It will show that the U.S. can be a leader," he said.
Politicians and investors are embracing the shift. Long a backer of oil and gas extraction along the Front Range, Gov. John Hickenlooper on Tuesday opened a national industry forum at a Vestas Americas turbine factory in Brighton — one of four Vestas plants in the state that employ 3,700 workers.
"This is a state issue for us. We view it as one of our highest priorities," Hickenlooper said.
Colorado initially looked to natural gas as a bridge away from coal-fired electricity, but "wind is going to take an increasingly large share of that as well," he said.
Today, "wind turbine technician" ranks as the fastest-growing occupation, according to the U.S. Bureau of Labor Statistics.
Utility giant Xcel Energy is playing a key role, purchasing electricity from 21 Colorado wind farms.
"We've cultivated wind as our most cost-effective renewable energy option because we recognize that this source of energy is not only a benefit to the environment but also a major economic driver for the state," Xcel's Colorado operations president David Eves said. "Our plan is to expand our wind offerings to provide hundreds of new jobs for Coloradans, make a billion dollars in new investments, keep energy costs low for our customers and improve the environment."
On Tuesday, Eves and Vestas Americas chief Chris Brown revealed a plan to build Colorado's largest wind farm on the Eastern Plains. If the Public Utilities Commission approves, this project would add 300 more wind turbines and produce 600 megawatts of electricity.

Industry analysts said wind's role will continue to expand.
And Vestas CEO Brown said the massive fiberglass blades made in Brighton may expand, too.
While installation of more transmission lines will be essential, shifting to clean energy in the future will hinge on "capturing more wind" with blades, he said.
Even a 1-meter lengthening of blades that now stretch 100 meters from tip-to-tip could more than double :o (http://www.createaforum.com/gallery/renewablerevolution/3-200714191258.bmp) the amount of electricity produced, he said.
"We want to have taller towers and bigger blades." (http://www.pic4ever.com/images/128fs318181.gif)

World's Biggest Windmills Now Make Jumbo Jets Look Tiny ;D
Even the plunge in crude prices since 2014 has failed to derail industry growth. (http://www.clipartbest.com/cliparts/xig/ojx/xigojx6KT.png)
“The doubling of turbine size this decade will allow wind farms in 2020 to use half the number of turbines compared to 2010,” said Tom Harries, an industry analyst at Bloomberg New Energy Finance. “This means fewer foundations, less cabling and simpler installation -- all key in slashing costs for the industry.”
The average turbine installed in Europe was 4.1 megawatts last year, 28 percent larger than in 2010, according to the London-based researcher, which expects 6.8 megawatts to be the norm by 2020. Harries said Siemens has hinted it’s working on a 10 megawatt turbine. :o (http://www.createaforum.com/gallery/renewablerevolution/3-200714191258.bmp)

Norwegian shipbuilder Ulstein has launched the first vessel featuring the new X-Stern hull design at their Ulstein Verft shipyard in Ulsteinvik, Norway.
The service operation vessel for the offshore wind industry is one of two being constructed for Bernhard Schulte Offshore, and will be working for Siemens.
The vessel is actually the first built by Ulstein Group for work in the renewable energy segment (http://www.createaforum.com/gallery/renewablerevolution/3-200714191258.bmp) , in this case offshore wind supporting wind farm operations and maintenance, technician accommodation and transport, and safe reliable access to offshore installations.
The X-STERN was first introduced in 2014 as the successor to Ulstein’s popular X-BOW hull. The X-STERN is designed so that a vessel can be positioned with the stern faced towards the weather instead of the bow, leading to improved weather resistance, greater operability and reduced power and fuel consumption while on DP mode.
Both vessels for Bernhard Schulte are based on the SX175 design measuring 88 meters in length, a breadth of 18 meters, speed of 13.5 knots, and accommodation for 60 people.
Ulstein received the order for the vessels in January 2015 by Germany-based Bernhard Schulte through its offshore wind affiliate WINDEA Offshore, marking the first order for the X-STERN hull.

DONG Energy Declares Option for Second Wind Farm Service Vessel (http://us.cdn2.123rf.com/168nwm/lenm/lenm1201/lenm120100200/12107060-illustration-of-a-smiley-giving-a-thumbs-up.jpg)
May 9, 2016 by gCaptain
DONG Energy has declared option for a second wind turbine Service Operation Vessel with Norwegian-based shipping company Østensjø Rederi requiring the construction of a newbuild vessel.
The newbuild will be sister vessel to the SOV awarded by Dong Energy last year and will function as a mother ship for wind turbine technicians servicing the Hornsea Project One wind farm located approximately 75 miles off England’s Yorkshire coast.
The 81.1-meter-long vessel will be a DP2 Service Operation Vessel with high station keeping capabilities, with 60 single cabins and accommodation for up to 40 wind turbine technicians and a crew of 20. The vessel will featured a motion compensated gangway system with an adjustable pedestal for safe operations and uptime. The vessel is also expected to be equipped with a helideck deck.
Delivery is anticipated for Q3 2018 from the shipbuilder Astilleros Gondan in Spain.
The Service Operation Vessels are designed by Rolls Royce in close cooperation with Østensjø Rederi. This will be the thirteenth vessel Østensjø Rederi builds at Astilleros Gondan, including three tugs and the one SOV already under construction.
“The new award is a further recognition of Østensjø efforts to expand our business into the renewable energy sector, following the strategy to diversify our operations. We are therefore very pleased that DONG Energy again has awarded us an exciting and important opportunity, says Kenneth Walland, CEO of Østensjø Rederi AS.
The contract with DONG Energy spans a firm period of five years with option for five more years.
The first SOV is scheduled for delivery in September 2017 and will service the Race Bank Offshore Wind Farm located in the North Sea about about 17 miles from the North Norfolk coast.
Galapagos Islands getting major renewable energy expansion

Galapagos wind © EOLICSA
The Galapagos Islands are most famous for the unique animal species studied by Charles Darwin and it's those species that have been the driving force behind the archipelago's quest to derive all of its energy from renewable sources instead of imported diesel fuel which still meets the majority of its energy needs.
Back in 2001, a fuel tanker bringing diesel fuel to San Cristóbal, the provincial capital, struck a reef and spilled about 570,000 liters of diesel oil which threatened the plants, birds and marine life that only call the Galapagos home. After that event, an international group created the $10 million San Cristóbal Wind Project which saw the installation of three 51-meter-tall wind turbines and two sets of solar panels in 2007.
That project, operated by the energy company EOLICSA, has managed to cover 30 percent of the electricity needs of San Cristóbal, the second largest island in size and population, and replaced the use of 8.7 million liters of diesel fuel since it began operation.
By helping its population avoid many tanker loads worth of risky diesel fuel imports since 2007, (http://www.siasat.com/news/wind-turbines-powering-galapagos-islands-2007-964390/) a global renewable energy project on the Galapagos Islands has offered hope that human population can ward off a catastrophic climate change and usher in an energy revolution.
A new planned expansion would boost renewable energy to covering 70 percent of the island's electricity needs on the way to hitting 100 percent. The new project would also serve as a blueprint for how to get the rest of the island chain to catch up. Currently, renewable energy only supplies 20 percent of energy demand for the other 18 islands, most of which are uninhabited.
The wind power project on San Cristóbal is notable not just because of how it has slashed fossil fuel usage, but because it has actually helped boost the health and numbers of the endangered species there. The project included an Environmental Management Plan when it was created that outlined ways to protect the unique bird populations, especially the Galapagos Petrel which is critically endangered.
The turbines are located on a hill far away from Petrel nesting sites and where there is little of the endangered Galapagos Miconia plant. Three kilometers of transmission lines were buried to avoid interfering with Petrel flights between their nests and the sea. The group has also carried out programs to reduce invasive species like feral cats, rats and plants that threaten the endangered species.
All the work has paid off. No Petrels have been harmed in the wind project's lifetime and the efforts to control pest species have led to an increased hatching success rate from 85 to 96 percent and the Petrel population seems to be growing. The environmental management portion of this project has shown that bird populations can be protected alongside wind turbines if the right precautions are taken.
The next stage of the project will see another wind turbine added, more solar power installed and an energy storage system to make the renewable energy more consistent and reliable.
New York Has a Plan to Make Long Island Offshore Wind Cheaper (http://cliparts.co/cliparts/Big/Egq/BigEgqBMT.png)
June 3, 2016 by Bloomberg
By Joe Ryan
(Bloomberg) — New York State is mounting a broad effort to reduce the cost of building a wind farm off the coast of Long Island, an ambitious push to generate clean power in U.S. waters. (http://www.pic4ever.com/images/19.gif)
The state’s Energy Research and Development Authority plans to bid for a federal lease to develop a 81,000-acre (127-square-mile) site in the Atlantic Ocean. If it wins, New York would undertake initial site studies and pursue an agreement to sell the electricity. The state would then hold an auction of its own, selling development rights to the highest bidder.
81,000-acre (127-square-mile) site in the Atlantic Ocean
New York officials see offshore wind as critical for meeting the state’s goal to get half its power from renewable sources by 2030. By doing the initial planning and guaranteeing a buyer for the power, the state intends to make the project appealing to developers, driving down costs and making it more likely the wind farm will be built.
“This is a resource that has to be, and will be, developed,” John B. Rhodes, president and chief executive of the New York State authority, said in an interview Friday. “It is our job to do it as surefootedly and cost efficiently as possible.”
Offshore wind is among the most expensive sources of power in the world. While it has thrived in Europe, the technology has languished in the U.S. as utilities balked at the price. If New York succeeds in lining up a buyer, the state would remove much of the risk for developers, and ultimately make the power cheaper for consumers, said Willett Kempton, a professor at the University of Delaware who studies offshore wind.
Kempton said in an interview. “No other state has done this before.”
“This is New York telling the country that offshore wind is going to happen, ”
The U.S. Bureau of Ocean Energy Management plans to auction off the lease for the site by the end of the year. The area, about 11 miles (18 kilometers) south of the city of Long Beach, is large enough to accommodate turbines capable of generating 900 megawatts, rivaling a nuclear power plant.
The first wind farm in U.S. waters, a 30-megawatt project off Rhode Island, is being built by Deepwater Wind LLC and scheduled to be operational by the end of the year. (http://www.clipartbest.com/cliparts/xig/ojx/xigojx6KT.png)

Iowa Will Soon Run on 40% Wind Energy
In April, Warren Buffet's MidAmerican Energy utility made a big announcement:
It will build the largest wind project in the US in Iowa (if approved by the state). The 2 gigawatt (GW) Wind XI will have 1000 turbines and could be producing electricity by 2018.
The utility's goal is to provide 100% renewable energy to Iowa customers and this $3.6 billion investment will get it to 85%. It would be the largest wind farm MidAmerican has built.
"We have a bold vision for our energy future. We don't know of another U.S. energy provider that has staked out this 100% position. Our customers want more renewable energy, and we couldn't agree more," says Bill Fehrman, MidAmerican Energy CEO.
And it will push Iowa's renewable electricity to over 40%, up from 31% now :o (http://www.createaforum.com/gallery/renewablerevolution/3-200714191456.bmp)- the most of any state, and where electricity rates are among the lowest in the US.
So, who says we can't get to 100% renewables fast?! (http://www.createaforum.com/gallery/renewablerevolution/3-200714183515.bmp)
"Just over a decade ago, Sierra Club's Beyond Coal Campaign cut its teeth organizing against three proposed coal plants in Iowa. After years of work by a handful of organizations that stopped several proposed coal plants and secured the retirement of other existing coal plants in the state, MidAmerican is now moving Iowa in a decidedly different direction," says Bruce Nilles, Senior Director of Beyond Coal.
Berkshire Hathaway Energy is one of 13 corporations to sign President Obama's latest effort on climate change, the American Business Act on Climate pledge.
The pledge: By the end of 2017, MidAmerican Energy will double renewable energy investments to $30 billion, bringing its portfolio to over 4 GW of wind - 57% of its retail energy load, and Pacificorp will buy over 1 GW of solar and wind, bringing its portfolio to over 4.5 GW - about 22% of its retail generating load. 75% of its coal-fired power plants will close in Nevada by 2019.
In Colorado, Xcel Energy is proposing the biggest wind farm in the state, the 600 megawatt Rush Creek Wind Project with 300 turbines. Similarly sized wind farms are also moving along in Texas.
All this is indicative of the US wind boom (http://www.pic4ever.com/images/maniac.gif)
Wind supplies close to 5% of US electricity and is expected to reach 10% by 2020 and 20% by 2030.
The industry employs 88,000 people, up 20% over the past year, and will grow to 380,000 jobs by 2030, according to the American Wind Energy Association's (AWEA) Annual Market Report.
"The challenge is to make renewable technology so cheap that it's the obvious choice," says Chris Brown, President of Vestas America and chair of AWEA.
Wind projects or wind-related manufacturing facilities (there are 500 in the US) are in all 50 states and over 70% of Congressional districts.
While China leads on sheer wind capacity, the US produces the most wind energy, enough for 17.5 million American homes.
Worldwide, wind led new power generation in 2015 and will nearly double over the next five years, says the Global Wind Energy Council (GWEC) Annual Market report.

Cleveland Soon to Be Home to the Nation’s First Offshore Wind Farm in Fresh Water
Lorraine Chow | June 6, 2016 2:49 pm
North America’s first offshore freshwater wind project has received a $40 million boost from the U.S. Department of Energy (DOE).
In somewhat of a surprise decision, the funding was awarded to Lake Erie Energy Development Co (LEEDCo) for its “Icebreaker” project, which consists of six 3.45-megawatt turbines located 8-10 miles off the coast of Cleveland.
The local wind power firm was chosen over Dominion Resources, which had proposed a two-turbine, 12-megawatt project off Virginia, and Principle Power, which had proposed a five-turbine, 30-megawatt project off Oregon. LEEDCo was previously considered one of the “alternate” projects.
According to Cleveland.com, “LEEDCo’s decision to adopt the European-designed ‘Mono Bucket’ foundation, which eliminates pile driving in the bedrock below the lake bed, may have been crucial to the DOE’s decision to fully fund the project.”
A DOE analysis stated that the “innovative Mono Bucket foundation will reduce installation time, costs, and environmental impacts compared to traditional foundations that require pile driving. The Mono Bucket not only is a solution for the Great Lakes, but also has broader national applicability for offshore wind installations off the Atlantic and Gulf Coasts.”
Lorry Wagner, LEEDCo’s president, told EcoWatch via email the team is “thrilled” to receive the federal award. “We always knew our project was a great one and over the last two years our progress demonstrated that,” he said.
Offshore wind power generation is a resource begging to be tapped. The U.S., however, lags behind other countries in utilizing this clean, renewable form of energy. In the U.S., offshore wind has a projected 4,223 gigawatts of electric generating potential, with Lake Erie’s waters alone accounting for more than 50 gigawatts of that power, as LEEDCo explained in an article.
According to Wagner, one reason why the U.S. has been slow in adopting offshore wind projects is due to political roadblocks (http://www.createaforum.com/gallery/renewablerevolution/3-311013200859.png).
“It always comes down to policy and we have not had much for offshore wind,” he said. “It is also true that onshore has been so successful, that offshore tends to get lost in the big picture. It will take a combination of policy and successful projects that will enable the industry to take hold.”
LEEDCo’s Icebreaker is currently the only freshwater wind project in development in the U.S.
Wagner explained that freshwater is ideal for a wind farm since the turbines are not exposed to elements such as salt water corrosion, hurricanes or the associated large waves in oceanic waters.
He also noted that Lake Erie is ideal for the Icebreaker project because it has uniformly shallow waters and has plenty of wind.
“There are over 2 gigawatts of available interconnect along the Ohio shore and we have an incredible manufacturing base that can industrialize the industry,” he said.
U.S. Rep. Marcy Kaptur (D-OH) announced the DOE’s $40 million grant to LEEDCo late last month at the Great Lakes Science Center in Cleveland, with remarks from LEEDCo senior officials, Cleveland Mayor Frank Jackson, Cuyahoga County Executive Armond Bodish and other Cleveland officials.
“Lake Erie is the Saudi Arabia of wind, and today’s award should be a gusher for northern Ohio,” said Kaptur, who serves as the Ranking Member of the U.S. House Energy and Water Appropriations Subcommittee. “This wind power project will begin to unleash Lake Erie’s full renewable power potential and contribute to creating a more competitive energy marketplace.”
“This announcement today seems perfectly suited to Cleveland, the first city in America where the electric wind turbine was invented. With this announcement today, Cleveland carries American innovation forward in this new millennium,” Kaptur said.
This is the fourth such award for LEEDCo. With the latest funding round, the non-profit will eventually receive nearly $51 million in federal support. The award money will go towards the design, manufacturing and construction phases of the Icebreaker as long as it continues to meet the DOE’s requirements. The project’s finish line is expected by the end of 2018.
LEEDCo has a 50-year lease from Ohio for its offshore project and is working to complete the remaining permits it needs from federal and state agencies. LEEDCo has secured a power purchase agreement for 65 percent of future output.
“The strength of the Icebreaker project, as opposed to its competitors, lies in LEEDCo’s commitment to leverage offshore wind energy with local Ohio-based jobs in the steel, construction and transportation industries,” Kaptur said. “This means local job possibilities beyond wind generation are on the horizon.”
Wagner told Cleveland.com that LEEDCo already has 15 local companies involved in the project and hopes to attract more, adding that fabrication and construction will create 500 jobs.
“Ultimately, we want to become the technology leader in the U.S. industry for offshore wind and environmental monitoring,” Wagner told EcoWatch.
The DOE also awarded another $40 million to the University of Maine’s New England Aqua Ventus I, a floating, 12-megawatt wind project off Maine’s shores.
Agelbert NOTE: Excellent. There is quite a bit of wind in the great lakes. It is fairly constant as well. It's high time we used that endless renewable energy resource.
For the naysayers that will poop poo wind turbines because of the risk to birds, I recommend they adopt some real world perspective and do an apples to apples comparison of the energy sources we now use.
Fossil-fueled facilities are 17-34 times more dangerous to birds on a per GWh basis than wind power. Heliostats, less dangerous than wind power to birds, have caused the deaths of hundreds of birds and wind turbines may have killed about 7000 birds, but fossil-fueled stations killed 14.5 million and nuclear 327,000.
Birds have excellent vision. Tiny wind powered LEDs on the turbine blades would prevent killing birds at night, when most of them are killed by moving blades.
Ulstein Delivers First X-Stern Wind Farm Service Vessel (http://www.pic4ever.com/images/19.gif)June 23, 2016 by Mike Schuler
Norwegian shipbuilder Ulstein has delivered the first of two new offshore wind farm Service Operation Vessels to Bernhard Schulte Offshore.
The vessel is the first to feature the new X-Stern designed by Ulstein. Its name will be revealed during a ceremony on June 30.
The vessel is based on Ulstein’s SX175 design, developed to meet the demands of servicing and maintenance of offshore wind installations. Its primary task will be to provide transport and accommodation services for technicians to the Gemini Offshore Wind Park, located approximately 53 miles north of Groningen, Netherlands.
Gemini Offshore Wind Park
The X-STERN was first introduced in 2014 as the successor to Ulstein’s popular X-BOW hull. The X-STERN is designed so that a vessel can be positioned with the stern faced towards the weather instead of the bow, leading to improved weather resistance, greater operability and reduced power and fuel consumption while on DP mode, making it ideal for
Ulstein received the order for the vessels in January 2015 by Germany-based Bernhard Schulte through its offshore wind affiliate WINDEA Offshore, marking the first order for the X-STERN hull.
The hull of the vessel arrived at the Ulstein Verft shipyard in Ulsteinvik, Norway in January 2016 after arriving from Poland, where the two hulls were constructed.
The 600 megawatt Gemini wind farm is operated by SIEMENS Wind Power Service. Once operational in 2017, the wind farm will be able to produce enough renewable energy to power about 780,000 Dutch households. ;D

Dong Energy to Develop World’s Cheapest Offshore Wind
July 6, 2016 by Bloomberg
By Celeste Perri
(Bloomberg) — The Danish utility Dong Energy A/S won a contract to develop two wind farms off the coast of the Netherlands that the Dutch government deemed the cheapest in the world.
Dong, the world largest offshore wind developer, offered to develop the projects for 7.27 euro cents a kilowatt-hour (8 U.S. cents), excluding connection fees for TenneT of 1.4 cents a kilowatt-hour, the Dutch economic affairs ministry said in a statement on its website Tuesday. The government said the move will allow it to spend 2.7 billion euros less than it had anticipated over the 15 years it will subsidize the project.
Map_borssele-UK_comIf completed, the projects will accomplish a goal Dong set four years ago to bring wind farm development costs under 100 euros per megawatt by 2020, the company said in a statement.
“This demonstrates the great potential of offshore wind,” Samuel Leupold, executive vice president and head of wind power for Dong, said in the statement. Dutch economic affairs minister Henk Kamp said Dong’s bid represents a “major breakthrough in the transition to sustainable energy.”
Dong will build the Borssele 1 and 2 wind farms about 22 kilometers (13.7 miles) off the Dutch province of Zeeland. The company plans to complete the projects by July 2020.
They will have a combined capacity of 700 megawatts, enough to power about one million Dutch households, Dong said. (http://us.cdn2.123rf.com/168nwm/lenm/lenm1201/lenm120100200/12107060-illustration-of-a-smiley-giving-a-thumbs-up.jpg) Offshore wind remains one of the most expensive ways to generate power. Dong, along with other developers, has cut costs dramatically in recent years with techniques that include making more efficient wind turbines and blades, improving foundation designs and boosting transmission-cable capacity.
The Netherlands is planing five new wind farms in the coming years to produce energy for more than 5 million households, the government said.

Using unconventional materials and real-world testing, a university-led consortium is poised to become a global leader in offshore turbines. (http://www.createaforum.com/gallery/renewablerevolution/3-200714183515.bmp)

Waves crashing over a 1:8 scale model of the VolturnUS floating wind turbine during a storm on Nov. 1, 2013, would be the equivalent of a 70-foot high surge, if the project was full size, University of Maine researchers have calculated. Their experience with the scale model off Castine has given confidence to predictions that full-scale floating wind turbines could survive a 100-year storm in the Gulf of Maine. Courtesy of the University of Maine
Gale-force winds and heavy rain lashed the Maine coast on Nov. 1, 2013. Power went out in parts of Hancock and Washington counties.
It was a perfect day to stay indoors (http://www.4smileys.com/smileys/seasons-smileys/storm.gif), and watch history being made in ocean energy. (http://www.pic4ever.com/images/19.gif)
At their computers, University of Maine researchers and their partners were monitoring data streams coming from 60 sensors on the VolturnUS wind turbine, their experimental, floating platform anchored off Castine. On a shoreside video feed, they could see waves nearly 9 feet high washing over the concrete platform, which was one-eighth the size of a full-scale unit. That was the equivalent of a full-size platform bearing the brunt of a 70-foot wave, bigger than any that could be expected in the Gulf of Maine every 100 years. *
But what they saw next was even more amazing: The turbine spinning 40 feet above the ocean had a pitch angle of only 5.9 percent, meaning that it was staying nearly vertical, despite the churning sea. (http://us.cdn2.123rf.com/168nwm/lenm/lenm1201/lenm120100200/12107060-illustration-of-a-smiley-giving-a-thumbs-up.jpg) That motion measurement mirrored the team’s computer models, vindication that they could predict how the platform would perform far offshore. (http://www.pic4ever.com/images/computer3.gif)
“That was the ah-ha moment,” said Habib Dagher, director of the Advanced Structures and Composites Center and the lead researcher on the project.
Dagher and his team made calculated gambles on several innovative strategies – from the unconventional materials used to make the platform and tower, the unusually large scale of the test platform, and the sheltered-yet-stormy location chosen to test them. Those calculations now are paying off.
MOST ADVANCED TECHNOLOGY
Three years later, the university-led consortium known as New England Aqua Ventus has the most advanced floating technology being developed in the United States.
Last month, the project was the only floating technology to win a $40 million federal grant, critical to building two full-size platforms for testing off Monhegan Island in 2018. Those platforms would hold 6-megawatt turbines, each with the capacity to power 3,000 average homes.
“Right now, it’s fair to say that the Maine project will be the first floating wind turbine in the United States,” said Walter Musial, manager of the offshore energy program at the federal government’s National Renewable Energy Laboratory in Golden, Colorado.
The government estimates that 60 percent of America’s offshore wind energy potential is in water too deep for steel towers to be buried in the seabed, as is common in Europe. Aqua Ventus offers the promise of tapping that power at a cost that can compete with fossil fuels, by mass-producing dozens of giant platforms and anchoring them far offshore, out of sight but close enough to bring a new, clean energy source to coastal cities. It also could create a new industry to build and service the platforms in Maine.
“The platform has to hold 400 tons 395 feet above the water and float in 70-foot waves during a hurricane,” Dagher said. “That’s what we’re trying to achieve.”
INSPIRED BY CONCRETE
Virtually all of the world’s ocean wind projects are made of steel. But Maine lacks steel mills and iron ore mines. What it does have is limestone deposits and New England’s only cement manufacturer, Dragon Products Co. in Thomaston. It also has a world-class composites center at UMaine that has years of experience developing breakthrough concrete and composite designs, from affordable, quick-build bridges to boat hulls that can handle high-speed stress. That’s where the Aqua Ventus team went for inspiration.
Their design – now being refined for a full-scale model – resembles three, upside-down concrete bridge columns that each will be 120 feet tall. They will be partly submerged and connected by 150-foot-long horizontal beams. The rotor of each wind turbine will spin 395 feet above the sea, turning blades 500 feet in diameter.
Platform of VolturnUS floating wind turbine
The platform will be built and assembled on land and towed to sea, just as the Castine prototype was. Once anchored on site, the hollow beams will be filled with seawater. These and other features pull down the platform’s center of gravity, making it more resistant to wind and wave motion.
“The design is simple to build,” Dagher said. “Bridge contractors can do this, and it can be produced locally. That drives costs down significantly.” (http://elqahera-trading.com/home/wp-content/uploads/2012/04/dollar-sign-thumbnail1.jpg) (http://www.createaforum.com/gallery/renewablerevolution/3-080515182559.png)
This approach is meant to solve challenges that make offshore wind energy costly to develop.
Steel is more expensive per pound than concrete and has less mass. Steel towers assembled offshore also need special “jack-up” vessels and cranes to lift them. Steel corrodes, unlike concrete. And steel is heavy, compared to the composite fiberglass tower holding the VolturnUS turbine. It’s half the weight of a comparable steel tower.
“Concrete was perceived to have a higher risk initially,” Musial said. “But a lot of those risks have been mitigated by the 1:8 scale project.”
The merits of concrete and composites caught the eye of DCNS Group, a French defense company that has been expanding in marine energy technology and has ocean energy projects in France and Nova Scotia. It has become a partner in the venture.
“From the design viewpoint,” said Frederic Le Lidec, DCNS’s marine renewable energy director, “we have conducted our own extensive due diligence on the VolturnUS hull technology, and reached a very positive conclusion about the quality of the UMaine design work, and potential commercial benefits of the technology.”
SEARCHING FOR BEST SITE
Offshore wind has borrowed a technique ;D from the oil and gas industry to test miniature versions of new structures in wave basins, essentially big swimming pools that simulate ocean conditions. The models typically are built to a 1:50 scale. VolturnUS had a similar 1:50 test, but Aqua Ventus then chose to build an intermediate-scale model and set it out in the real world. No other floating wind project has done that.
“The VolturnUS 1:8 scale experiment off Castine provided very important data to validate the modeling tools and the performance of the design both in operational and extreme storm environments,” Le Lidec said.
Full-size pilot projects rarely experience 100-year weather events, so it’s hard to predict their performance in the worst conditions. The data collected by the 1:8 scale platform, Le Lidec said, can assure investors that the platform will perform at a commercial scale in the nastiest weather.
To find the best site for VolturnUS, researchers used wind- and wave-measuring buoys to study locations along the Maine coast. After a year of data collecting, they settled on a spot off Dice Head in Castine that had a high probability of seeing the desired 1:8 scale waves and wind.
Dice Head Lighthouse
Castine (Dice Head on the left)
The $1 million prototype was built by Cianbro Corp., an Aqua Ventus partner, and towed out in June 2013. The prototype remained in the water for 18 months, during which time the platform and turbine experienced 40 storms with intensities that could be expected within 50 and 500 years. It was a good move to test off Castine, Musial said, instead of the open water off Monhegan.
NOTE: Dice Head is closest to your view
“They were able to demonstrate a lot more at the site,” he said. “Penobscot Bay was sheltered enough that it didn’t wipe the whole machine out. The design would have been exceeded at Monhegan.”
‘NO ONE TALKED ABOUT CONCRETE’
The Aqua Ventus team now is finalizing the full-scale design package and is on track to gain formal commitments from unnamed investors next year. At the same time, it’s collecting data at the proposed Monhegan test site using a laser technology that can clock wind speeds 395 feet in the air, the hub height of the wind turbines. 8)
While the Aqua Ventus technology has won support from the U.S. government, other floating designs are competing for global attention and investment.
UMaine’s chief rival in the Department of Energy grant competition, Principle Power, failed to win a power contract with a utility in Oregon and was cut from consideration. But the company recently concluded testing a 2-megawatt steel platform called WindFloat off Portugal, and is planning multi-unit floating farms in Europe and Japan. (http://www.createaforum.com/gallery/renewablerevolution/3-080515182559.png)
Statoil, the Norwegian energy company that pulled the plug on a proposed test project in Maine in 2013, is building a 30-megawatt steel wind farm off Scotland. (http://www.createaforum.com/gallery/renewablerevolution/3-080515182559.png)
And recently, floating-wind researchers are developing an interest in concrete. Testing has begun on a hybrid concrete-steel platform in Japan; a concrete design is being built in France and another is proposed in Spain. In a news release last month, the Spanish developers of Windcrete noted that it could be built in dry dock, towed to sea and partially flooded with seawater, avoiding the expense of floating cranes.
These benefits sound familiar to the Aqua Ventus team. ;) ;D
“No one talked about concrete until we put ours in the water,” Dagher said.

July 12, 2016 — 2:48 AM EDT
Two thirds of state’s power needs come from wind over weekend
More than 40% of power derived from renewable energy in 2015 (http://www.4smileys.com/smileys/seasons-smileys/storm.gif)
Wind farms supplied more than two thirds of South Australia’s electricity at the weekend, with an even bigger contribution on Monday in a sign of the state’s growing embrace of clean energy.
Wind provided 83 percent of the state’s power needs in the 24 hours to 4 p.m. on Monday when turbines helped turn the wild weather whipping the state into renewable energy, Australia’s Clean Energy Council said in an e-mailed statement on Tuesday.
South Australia got more than 40 percent of its power needs from renewable energy last year, the council said, adding that the state’s 683 turbines have generated more than $6 billion of investment.
Wind energy is helping many nations, including Australia, to cut emissions from the power sector. Other mainland states could follow South Australia to use more renewable energy, according to the council.
Wind-power capacity in Australia may surge almost 56 percent by 2018 from 2015 levels, according to Bloomberg New Energy Finance forecasts.
“New technologies such as battery storage are falling in price, and will act as a perfect complement to smooth out the supply of renewable energy in the future," Alicia Webb, the Clean Energy Council’s policy manager, said in the statement.
— With assistance by Feifei Shen
Agelbert NOTE: As the scientific consensus has argued for several years, and I have posted about for about 4 years, global warming increases average wind speeds all over the planet. Consequently, every wind turbine out there will return a greater amount of energy than the fossil fuel industry shills like Charles Hall have claimed, as well as being less intermittent and more reliable with more wind AND larger and cheaper battery storage technology.
But even Charles Hall gave wind turbines an ERoEI of 18:1 in 2012 AND added that the bigger they are (they have gotten a LOT bigger since then), the higher (above 18:1) their ERoEI gets. ;D
In the light of these wind increase facts, I would not put it past the fossil fuel industry to claim that, since burning their hydrocarbon product is DIRECTLY responsible for the increased wind ENERGY those turbines are getting from climate change caused increased wind speeds, they should get a cut of the energy profits from wind turbine Renewable energy.

Expansion of onshore wind energy in Germany in the first half of 2016
Strong expansion before the switch to tendering
With a net capacity of 1,892 megawatts in the first six months of the year, 2016 looks like being a good year for land-based wind energy expansion. This strong expansion is being driven by the allocation of suitable sites and priority areas in many federal states. There has also been a surge of permits in order to secure the option of installing turbines with legally fixed EEG remuneration rates. In Germany the wind industry is working hard to develop innovation and production bases further. It also aims to use its leading technology to further expand its strong position in what are generally stable markets abroad.
Berlin, 28 July 2016 – Onshore wind energy in Germany was extended by a net capacity of 1,892 megawatts in the first half of 2016, representing a growth of 73 per cent over the same period the previous year (1,093 megawatts). Factoring in the number of dismantled turbines and the 161 megawatts of repowered turbine capacity in the first six months, this gives a gross capacity increase of 2,053 megawatts. This means a third strong year in a row for reasonably priced onshore wind energy. Taking projects that have already been granted planning permission into consideration, the industry associations VDMA Power Systems and German Wind Energy Association BWE predict a net volume of between 4,000 and 4,400 megawatts for the whole year.
Stronger expansion in 2016 due to increased wind zoning
The strong extension in the first half of 2016 has been driven by the allocation of suitable sites and priority areas. The zone allocations made in the federal states last year continue to have an effect, even though some have been revoked as a result of political decisions in Bavaria or judicial decisions in Schleswig-Holstein. The availability of space also explains some of the significant regional variations. “The German market is concentrating less on the coastal states, and developing in an increasingly balanced manner. This is underlined by the healthy development in the typically landlocked states. Federal government must re-evaluate the restriction of expansion in regions with grid bottlenecks as early as 2018 so that this can be reversed if and where necessary”, says Hermann Albers, president of the BWE.
Forecast for 2017 dependent on existing approvals
The industry expects a similar level of growth for 2017 as in this year. By the end of May projects have been approved with a total volume of around 3,200 megawatts. A large proportion of these will have been realised by the end of this year. Operators and official agencies are expecting a further surge of approvals by then. Whoever secures approval before the end of the year and erects their turbines in 2017 or 2018, will still get the legally fixed rates of remuneration for the power they produce. The extraordinary degression starting in March 2017, and particularly the intensified degression from October of the same year render expansion clearly less attractive. “Although we will see a significant decline in new builds over the year, it will probably have virtually no impact on the overall capacity that will be installed in 2017. This is because higher turbine yields will to a certain extent compensate for the drop in remuneration”, says Matthias Zelinger, managing director of VDMA Power Systems. It can be assumed that in 2018, the second transition year, there will be significantly less expansion, he adds. “We expect that most of the projects approved by the end of 2016 will be realised in 2017, and will not be involved in tendering. The extension in 2018 will primarily consist of the tenders awarded in 2017.”
Working harder to develop business bases
While there is still uncertainty amongst developers, manufacturers are in principle taking a positive view of controlling quantity through tendering, as long as it secures continuous expansion, fosters greater competition and contributes to market proximity. Production and product development will have to be adjusted to a market volume of initially 2,800 megawatts a year. Attention should however be paid to ensure that the legally fixed tender quantities do not lead to the stagnation of what has up to now been a positive development of the wind industry in Germany. Projects that are not realised, despite winning a tender, must not be allowed to curtail the volume of expansion in the long term. These quantities must be taken into consideration in later tenders, because in the long term an ambitious expansion and a lively market, also with regard to quantity, is necessary if the manufacturers are to maintain their technological leadership and their production capacities in Germany. Up to now the manufacturers have owed their strong position, also in the global market, to the fact that the technology was being further improved in the German domestic market. “This didn’t just happen by itself. Innovative strength has always required hard work in this industry, and now it needs even harder work.” states Zelinger.
World market at the same high level
The demand for leading turbine technology Made in Germany in international markets has remained at the same high level. VDMA Power Systems forecasts a global market for onshore wind turbines in an order of magnitude of 55,000 megawatts in 2016, which will continue the same in the following years. Due to their current strong role in the worldwide consolidation process, German companies have the chance to expand their position in growing markets. The largely closed Chinese market on the other hand remains a problem. Strict demands regarding the local share of value creation hamper competition in other markets. This is where the federal government should be working harder for fair market opportunities of the German wind industry.
The energy system’s cheaper key player
In Germany, onshore wind production is still a cost-effective key player in the shift to renewable energy use. The nationwide strong expansion makes sense as far as energy production is concerned. “Nowadays wind forecasts are very precise. The actual amount that is fed into the grid hardly deviates from what is forecast. Wind turbines provide important system services, such as maintaining voltage stability. It would make sense to integrate the turbines into the redispatch system. There are also alternatives to reducing production in the event of grid bottlenecks. We welcome the opportunity provided by EEG 2017 to use this electricity before it reaches the grid junction point. This has created the first interfaces for sector coupling. Producers can develop their own markets by means of business-to-business solutions. This is fully in keeping with market integration and makes a serious contribution to system transformation. It also supports the achievement of the federal government’s climate protection goals”, says Hermann Albers.

Wind turbines in the German North Sea
Press release | 2016-08-10 | 15:00 PM
Vattenfall acquires German wind development project
Vattenfall has acquired a wind development project consisting of up to 79 turbines in the German North Sea. The acquisition is in line with Vattenfall’s growth strategy to extensively expand its renewable energy production in the coming years.
The Global Tech II wind project is located in the German North Sea some 85 kilometres north of the island of Borkum. The project is currently under development with up to 79 wind turbines in an area of 47 square kilometres.
“The acquisition underlines once more that our growth ambitions in wind are under full steam. As a company we are on a good way to reshape our generation portfolio towards more renewable energies in all our markets”, says Gunnar Groebler, Senior Vice President and Head of Business Area Wind at Vattenfall.
The Global Tech II project is owned by Northern Energy Global Tech II, which Vattenfall has acquired as of 5 August. The seller is Erste Nordsee-Offshore-Holding, a joint subsidiary of Austrian STRABAG SE and indirecly Etanax GmbH. The parties have agreed to not disclose the purchase price.
“With Global Tech II we also send a signal that we strongly believe in the German market. In particular we consider the new German tender system beneficial to the development of wind as it is more cost efficient, which will also lead to further acceptance of this effective and renewable power generation.”, says Gunnar Groebler.
The realization of the project depends on obtaining a capacity contract in the tendering process whth the first auction in March 2017 and the second auction in March 2018.
Vattenfall wind power
Vattenfall operates over 1,000 wind turbines with a total installed capacity of 2,000 megawatts (MW). In 2015 Vattenfall’s wind power production amounted to more than 6 TWh. By 2020 Vattenfall expects to double its wind capacity to 4,000 MW and invest more than SEK 50 billion, (approximately EUR 5 billion euros) in wind.

MA Makes Nation’s Largest Offshore Wind Power Commitment!
Amber Hewett | August 1, 2016
One of many United Kingdom offshore wind farms.
I’m so proud to say that the Bay State, my home state, just made history. Late last night, in the final moments of the Massachusetts legislative session, leaders on Beacon Hill passed an energy bill equipped to finally launch America’s offshore wind industry!
This is great news for wildlife, and for all of us counting on our leaders to take swift, bold action to confront climate change. Massachusetts has stepped up to demonstrate just how offshore wind power can play a key role in addressing the massive energy and environmental challenges of our time.

Legislation passed last night commits the Commonwealth to bringing 1,600 megawatts of offshore wind power online. (http://www.pic4ever.com/images/19.gif)
That’s enough clean, local energy to power more than half a million homes while creating thousands of long-term, high quality jobs.
Massachusetts will be on track toward a truly clean energy future – one where our energy portfolio reflects the need to protect our communities and wildlife from the dangers of climate change. The MA legislation’s commitment shows a prioritization of public health, clean air, and clean water – all while buffering ratepayers from the volatile fossil fuel market.
“The Massachusetts Legislature hit a home run tonight. All eyes are now on Governor Baker to sign the bill and make this pivotal commitment to offshore wind power a reality.”
– Catherine Bowes, National Wildlife Federation

This milestone has been a long time coming in Massachusetts. We have a world-class wind resource off our shores, ready to serve as the foundation for a new clean energy economy in the Commonwealth. While our neighbors across the Atlantic have been growing offshore wind power into a booming global industry for 25 years, we have yet to get a single turbine into U.S. waters (though that is changing this summer with the Block Island Wind Farm!).
Massachusetts’ leadership here is pivotal. With America’s first offshore wind project finally under construction, bold policy commitments from state leaders are precisely what’s needed to ensure this is truly the beginning of a new energy chapter. Among all of the lasting benefits listed above, what arguably makes this bill most significant is the example it will set.
Over the next decade and beyond, offshore wind power will replace retiring nuclear and coal-fired power plants in New England and show state leaders up and down the coast that we can power our homes and businesses with local, clean energy. (http://www.desismileys.com/smileys/desismileys_0293.gif)
The Massachusetts legislature just turned the tide in a way that will unleash the nation’s largest untapped clean energy opportunity! It’s a new day, and a turning point in our endlessly important pursuit of a responsible energy future. (http://www.bativert.ma/images/image3.jpg)
Of course, there is a long road ahead to get these turbines up and running, and the next step is getting this historic bill signed by Governor Charlie Baker.

Could Offshore Wind Replace Nuclear Power? (http://www.desismileys.com/smileys/desismileys_1730.gif) (http://www.desismileys.com/smileys/desismileys_1402.gif)
August 16, 2016 by Bloomberg
by Jessica Shankleman (Bloomberg) Britain could scrap the 18 billion-pound ($23 billion) nuclear power plant at Hinkley Point and get the same amount of electricity from offshore wind turbines for roughly the same investment. (http://www.createaforum.com/gallery/renewablerevolution/3-200714191258.bmp)
That’s the assessment of Bloomberg New Energy Finance following Prime Minister Theresa May’s decision to review whether to proceed with the first new atomic plant in more than three decades.
For the same capital costs, the U.K. could install about 830 new turbines at sea, which would generate 25 terawatt hours a year — the same amount of power the Hinkley reactors would produce, according to the London-based researcher.
Aglebert NOTE: Not to mention the FACT that sea side wind turbines in Japan were unscathed by the giant tsunami when all the nuclear reactors were put out of commission or melted down to pollute every living thing around them.
Not to mention the FACT that we-the-people have to bear the cost (i.e. nuclear welfare queen subsidy THEFT) of insuring nuclear power plants because, although private insurers will gladly insure offshore wind turbines, they will NOT insure nuclear power plants.
Not to mention the FACT that Nuclear power plant capital costs CONTINUE after being built BECAUSE they need more fuel rods from polluting mining and manufacturing operations.
Not to mention the FACT that Wind turbine maintenance is much less hazardous, while maintenance costs are much lower than that of a nuclear power plant. Yes, you need more people (i.e. MORE JOBS! ;D) to maintain a lot of wind turbines. But the elimination of the COSTS to we-the-people of insuring nuclear power plants, providing sweetheart financing and guaranteed energy price rates more than offsets the cost to employ all these people.
Wind power is a win win for biosphere AND the economy. Nuclear power is the exact opposite.

Finishing touches on turbine #5! Photo by Deepwater Wind[/color][/b]
The fifth and final turbine has been installed at the Block Island Wind Farm – and with that, the nation’s first offshore wind power project is now just weeks away from generating clean, local, wildlife-friendly energy.
From earning unanimous approval from state officials in 2014, to achieving full financing in 2015, to putting hundreds of Rhode Islanders to work on the project – including building the first U.S.-flagged offshore wind power crew transfer vessel – to finally putting steel in the water in 2015 to kick off a new energy chapter in America, Deepwater Wind has blazed the trail and created a shining national model for offshore wind development in America. With strong measures in place to protect wildlife including the endangered North Atlantic right whale every step of the way, the Block Island Wind Farm demonstrates that offshore wind development can be compatible with ocean conservation. The National Wildlife Federation proudly points to the success of the Block Island Wind Farm as clear evidence that a truly responsible energy future is possible.
It’s a new day! Photo by Deepwater Wind (at article link)
With a new energy policy on the books in Massachusetts equipped to finally launch a robust offshore wind power industry, there is no doubt that the Block Island Wind Farm can be the start of something big. We are witnessing America reach for the incredible clean energy potential off our shores, and now we can begin to catch up with other countries around the world that are 25 years ahead of us in tapping into this booming global industry.

DONG Energy Installs World’s Largest Wind Turbine
September 12th, 2016 by Joshua S Hill
Danish wind energy giant DONG Energy has completed the installation of the world’s largest wind turbines at the Burbo Bank Extension offshore wind farm in England.
DONG Energy announced last week that it had successfully completed the installation of the first of thirty-two 8 MW wind turbines at the Burbo Bank Extension offshore wind farm which it is developing, currently under construction in Liverpool Bay, off the west coast of England.
The 8 MW wind turbines, built by Vestas, are the largest in the world, standing at 195 meters — in excess of two Big Bens.
This is the first time Vestas’ V164-8.0 MW wind turbines will be used in an offshore wind farm, though certainly not the last, as the number of extra-large-scale offshore wind farms continue to grow. Upon completion, the Burbo Bank Extension will have a final capacity of 258 MW, and generate enough electricity to supply approximately 230,000 UK homes with clean electricity.
“The installation of this world-first technology shows that DONG Energy is leading the way in offshore wind energy,” said Claus Bøjle Møller, Project Director at DONG Energy. “By using bigger turbines, we’re able to bring down the cost of providing clean, renewable energy to homes around the UK. This first turbine is a significant achievement for the project, and we’re looking forward to producing the first green energy later this year.”
Yet another record low price for offshore wind energy (http://www.pic4ever.com/images/8.gif)

Offshore wind has a lot of things going for it. Whether it's less intermittency, a lack of NIMBY neighbors, or the sheer room to scale, we have good reason to believe that it will play an increasingly important role in electricity production around the world. (http://www.pic4ever.com/images/128fs318181.gif) (http://www.desismileys.com/smileys/desismileys_0293.gif)
Until recently, however, there was one major drawback: price.
Here too, however, there's been progress. Just earlier this summer, for example, there was considerable excitement when DONG Energy delivered a tender for a Dutch wind farm with a strike price of €72.70/MWh, beating the industry's 2020 goal of €100/MWh by several years and more than €27. And now it looks like that particular bid wasn't an outlier, either.
In fact, Bloomberg is reporting that Vattenfall AB just delivered a tender to build two offshore wind farms, with a total capacity of 350 megawatts at €60/MWh—in other words 20% lower than the lowest ever bid set earlier this year! It'll be interesting to see if prices like these are the new normal. If so, we can fully expect the offshore wind industry, in Europe at least, to take off at a pretty rapid pace.
Meanwhile, the US is about to usher in its first commercial scale offshore wind farm. And while the 30 megawatt capacity pales into insignificance compared to the huge farms already operating elsewhere in the world, there's good reason to believe that it's a sign of bigger, better and cheaper things to come for this promising industry.
Signs That Wind Power Is Gaining Strength in the U.S. Posted on Sep 19, 2016
Europe’s Offshore Wind Industry Eyeing Atlantic Crossing
September 23, 2016 by Reuters
By Christoph Steitz
FRANKFURT, Sept 23 (Reuters) – Yield-hungry investors in the offshore wind market are switching their sights to the United States as future support for the industry in Europe remains uncertain, leaving billions of euros looking for a new home.
The shift in focus comes as three states on the U.S. east coast — Massachusetts, New Jersey and New York — are auctioning leases on hundreds of thousands of acres for offshore wind farms, drawing interest from leading European companies.
Europe has led the way in developing offshore — the most expensive form of renewable energy — but few of the continent’s cash-strapped governments have given firm plans for support beyond 2020 for a sector still dependent on subsidies.
Putting turbines that stretch 200 metres into the sky in waters 50 metres deep, miles out in stormy seas, is a costly business. New farms take years to plan and build but European governments want to wean developers off subsidies to try to drive down prices.
Despite the cost and complications, American states are tapping into a clean and plentiful source of energy sitting on their doorstep.
A growing U.S. sector would prove another market for investors and equipment makers such as DONG Energy, Germany’s Siemens and Denmark’s Vestas.
In need of at least 1 billion euros ($1.1 billion) of investments each, offshore farms are bigger, benefit from stronger winds and raise fewer environmental protests than those located on land.
They can also generate low double-digit returns for the owners who are prepared to take the initial risk of funding them, according to renewable finance specialist Green Giraffe.
“Many players have cast an eye on the U.S. market,” said Udo Schneider, director at Green Giraffe, which helped to fund more than 35 offshore farms worldwide, including Block Island off Rhode Island, the first such site in the United States.
“Investors are looking for an alternative to Europe.”
EUROPE SETS THE PACE
Having developed a global edge in technology and supply chain management, Europe’s offshore wind industry has attracted 60 billion euros since 2010, lifting capacity to 11.5 gigawatts (GW), more than 90 percent of the world’s total.
One gigawatt is roughly the capacity of a nuclear plant.
A further 12 GW, including the huge Hornsea project off the coast of northern England, is expected to be added by 2020 but uncertainty over how the sector will be supported beyond that is already hitting investment.
After raking in a record 14 billion euros in the first half of 2016 alone, industry group WindEurope expects spending to drop to just 5.2 billion by July 2017.
Major players are already expanding outside Europe, with asset manager Copenhagen Infrastructure Partners (CIP) buying a 675-square-km offshore lease south of Massachusetts last month, where it expects to build a 400 megawatt (MW) site.
In Europe, CIP holds stakes in biomass plants and wind assets in Britain, a converter station that connects offshore parks in the North Sea with the mainland, as well as wind projects off the coasts of Scotland and Germany.
“It’s natural to look for growth outside Europe. I think the U.S. east coast is very interesting. It has a high population and strong winds, which is crucial to offshore,” said Christina Grumstrup Sorensen, senior partner at CIP.
An energy bill passed in Massachusetts last month meant investors now had a good reason to enter the market, she added, declining to say how much CIP had paid for the lease.
Under the law, utilities are required to take 1.6 GW of offshore wind power by 2027, the biggest commitment made so far to the industry in the United States.
“Overall there is potential for more than 5 GW in Massachusetts,” said Martin Neubert, chief strategy officer of wind power at Denmark’s DONG Energy, which has built more than a quarter of the world’s offshore wind farms and holds a 1 GW lease in the U.S. state.
DONG also this year bought a lease to build 1 GW of capacity off New Jersey.
It is still pondering whether to bid for a lease in New York to be auctioned later this year, which could hold up to 700 MW of offshore capacity and has caught the eye of rival investors, including French utility EDF.
The industry argues it needs substantial volumes to bring down the costs for offshore from around 125 euros per megawatt hour (MWh).
It is unclear whether Europe will commit to the 4-7 GW per year the industry says is needed from 2021 to bring average costs below 80 euros per MWh — a level where it can compete with conventional energy sources, such as coal.
Recent tenders in the Netherlands and Denmark, won by DONG and Sweden’s Vattenfall, suggest that the industry is capable of cutting costs to such levels, but the projects feature unique conditions and do not include costly network connections.
Based on current commitments — including those from Britain and Germany, the two largest offshore wind markets — European demand is expected to grow by only about 2 GW annually during the next decade.
Sam Arie, who leads European utilities research at UBS, said the U.S. offshore market could contribute 1-2 GW of capacity in the medium term, adding existing industry players would be best placed to benefit from this.
“In the first phase we would expect DONG and its partners to play at least some kind of role – you wouldn’t expect the U.S. to be re-inventing the supply chain from scratch,” he said.
This would also benefit Siemens and MHI Vestas — a joint venture between Japan’s Mitsubishi Heavy Industries and Vestas — which together hold more than 80 percent of the global offshore wind turbine market.
Siemens, by far the market leader with more than 7 GW of installed offshore wind turbine capacity, expects large scale projects to materialise in the next decade and “stands ready” to support the U.S. sector, it said in emailed comments.
There is a catch and a cost.
Since most of the production is still based in Europe, the likes of Vestas, Siemens and General Electric would need to set up production of sea-bound turbines along the east coast.
Even though they have a strong presence in the country’s onshore market, offshore turbines are much bigger and more difficult to transport, Macquarie analyst Gurpreet Gujral said.
“I don’t see them shipping blades over the Atlantic.” ($1 = 0.8973 euros)

New wind turbine that harnesses the energy of typhoons could power Japan for 50 years (http://www.createaforum.com/gallery/renewablerevolution/3-200714191258.bmp)
By Rob Thubron on September 30, 2016, 6:15 AM
Japan feels the devastating effects of typhoons several times per year – in 2016 alone there have already been six. They can cause a trail of destruction, along with many dead and injured civilians who get caught in their path. But an engineer from the country has designed a new type of wind turbine that can harness this immense energy and use it for good.
Atsushi Shimizu claims that a series of his prototype devices could collect enough energy from a single typhoon to power the whole of Japan for 50 years.
The unique, egg beater-shaped turbine’s omnidirectional vertical axis can withstand an intense storm’s powerful winds and rain. Moreover, the speed of the blades are adjustable, meaning they won’t spin wildly out of control – a big problem with super typhoon speeds reaching up to 150 mph.
The Fukushima disaster * saw Japan turn away from nuclear power. It now imports 84 percent of its energy requirements. "Our generation reaped the benefit of nuclear power - we never experience a power blackout because of it," Shimizu says. "Now we are responsible for changing the future."
* Agelbert NOTE: The Wind Turbines along the coast were unscathed by the tsunami and gave power when all other power plants were down after the tsunami ;D. Of course a vertical axis type turbine would handle high winds better, but the current ones can already handle tsunamis.
CNN reports that while Japan has tried to use wind energy in the past, the attempts have largely proved unsuccessful.
"For decades, Japan has brought in European-style wind turbines, not designed for typhoon zones, and installed them with no careful consideration - they've broken almost entirely," added Shimizu.
Modern, propeller-based turbines generally achieve a 40 percent efficiency rate. While Shimizu’s turbines hit 30 percent efficiency, their advantage is that they can work during a typhoon.
Shimizu’s company, Challenergy, installed one of the prototypes in Okinawa earlier this year. He now wants another to be located either on the Tokyo tower or at the new National Stadium. A method of storing 50 years of power would also be helpful.
Wind Sector Soars
A record 20 gigawatts (GW) of wind capacity is currently under construction in the US, joining the existing 75 GW fleet, the American Wind Energy Association’s (AWEA) quarterly report shows.
Iowa also became the first state to generate more than one-third of its electricity from wind power.
Though new wind installations fell in the third quarter of this year compared to 2015, continued investment in renewables is driving new construction. The recent five-year extension of the tax credit for wind projects has considerably lowered the deadline pressure for developers.
Agelbert NOTE: The new Vermont NIMBY stupidity (http://www.pic4ever.com/images/gen152.gif) begins. (http://www.createaforum.com/gallery/renewablerevolution/3-200714183337.bmp) NONE of these people have EVER complained about the sound levels of cars and trucks on the highways in front of their homes. THOSE sound levels are FAR above anything the wind turbines make. But these stubborn, hide bound, fossil fuel worshipping NIMBY fools in Grafton and Windham prefer being slowly poisoned by exhaust emissions from cars and trucks along with the noise pollution of internal combustion engines (never mind the 24/7 CO2 pollution they emit :P) than clean energy from wind turbines. :(
Voters renounce Stiles Brook Wind planNov. 8, 2016, 11:15 pm by Mike Faher
WINDHAM – Voters in Grafton and Windham on Tuesday resoundingly rejected a 24-turbine wind project proposed for a ridgeline separating the two towns.
In Grafton, residents voted 235 against and 158 in favor of the Stiles Brook Wind Project, according to town officials. In Windham, the vote was 181 against and 101 in favor.
Developer Iberdrola Renewables will honor those votes and “cease development of the Stiles Brook Wind Project unless the communities reconsider their decision,” spokesman Paul Copleman said.
Copleman also said the company was “disappointed by the unfortunate outcome” of the balloting. But opponents of the project immediately celebrated.
“I really did think it would be like this,” said Windham Selectboard Chairman Frank Seawright. “Living here in New England, I think there’s a lot of people who do have respect for democracy and local government.”
In Grafton, opposition groups issued a statement saying they will “fight to the end to preserve our ridgelines in Vermont. We will seek energy solutions that make less of a footprint while respecting Grafton’s own unique environment and character.”
Prior to Tuesday’s vote, Iberdrola spent years developing the Stiles Brook proposal. Initial plans called for 28 turbines to be built in Stiles Brook Forest, but the company downsized that by four turbines in early October.
That move was designed to lessen the project’s visual and noise impacts, Iberdrola said at the time.
Simultaneously, the company increased the “community benefit” package for the two towns from $1 million to $1.5 million annually. That included “partnership payments” totaling $565,000 annually to residents of Windham and Grafton if the wind project was constructed.
At the time, critics said the payment offer amounted to bribery or undue influence on the pending votes. The state attorney general’s office disagreed, though Secretary of State Jim Condos eventually spoke out against any payments offered to registered voters.
That was just one example in a long line of disputes over the Stiles Brook proposal. Critics, including several Windham officials, vehemently argued that the turbines could have negative impacts on aesthetics, property values, the environment and even human health.
Two grass-roots opposition organizations – Grafton Woodlands Group and Friends of Windham – sprang up to oppose the project.
But Iberdrola and Stiles Brook property owner Meadowsend Timberlands Ltd. defended the plan, saying the Stiles Brook turbines would be an important source of renewable energy and would combat the effects of climate change.
Iberdrola said turbines would not harm neighbors’ health and accused opponents of spreading false information.
An energy project like Stiles Brook requires a state certificate of public good, and towns don’t have veto power. But Iberdrola administrators repeatedly said they would abide by the results of Australian Ballot votes by residents of Windham and Grafton.
Both towns also conducted surveys of nonresident property owners after there was an outcry by second-homeowners, who cannot participate in a town election. Those surveys are supposed to be tallied in both towns on Wednesday.
But those nonresident results won’t have any effect on Iberdrola’s decision to suspend the project.
“We are grateful for our supporters’ efforts and for the significant portion of the local community that supported the project,” Copleman said Tuesday night. “We are confident that the project would be a valuable and significant benefit to the local communities of Grafton and Windham, while also making an impact towards energy independence and climate change.”

World's Cheapest Offshore Wind Farm to Power 600,000 Homes
Trump rages against German wind power
US president elect Donald Trump’s negative comments on wind power in a recent interview with the New York Times present a concern for both the domestic and international wind sector, writes Franz Hubik in Handelsblatt. “Trump made clear that climate protection and renewable energies are not a priority for him.
The conditions for wind turbine manufacturers could significantly worsen in the United States under Trump (http://www.createaforum.com/gallery/renewablerevolution/3-200714183337.bmp),” Sven Diermeier, analyst at Independent Research, told Handelsblatt. German companies like Siemens and Nordex could suffer.
Hermann Albers, president of German Wind Energy Association (BWE), is more optimistic: “Renewables are domestic forms of energy that actually support his goal to strengthen the US economy and employment. We should debate this with the Americans.”
Agelbert NOTE: Hermann Albers would do well to temper his optimism. If the infrastructure for energy isn't fossil fuel based, Fossil Fuel Polluter Defender Trump will NOT support it. (http://www.createaforum.com/gallery/renewablerevolution/3-120716190938.png)

Dutch marine contractor Van Oord has been hired to build Belgium’s largest offshore wind farm project located approximately 23 kilometers off the Zeebrugge coast in Belgium.
Van Oord announced Friday it has signed a contract with developer Norther to provide Balance of Plant works for the Norther Offshore Wind Farm. With capacity to generate 370 MW, the wind farm will be Belgium’s largest and will deliver renewable energy to approximately 400,000 households.
The Van Oord services will include the engineering, procurement, supply and installation of the 44 WTG foundations, the Offshore High Voltage Station and the inter-array and export cables, and the installation of the turbines. For the transport and installation of the foundations and turbines Van Oord says it intends to deploy its offshore installation vessel Aeolus and cable-laying vessel Nexus.
With the use of wind energy increasing, specifically in places like northwest Europe, Van Oord says it is positioned at the forefront of truly sustainable project.
“As one of the leading marine contractors we have completed several prominent offshore wind projects in the past fifteen years,” said Van Oord CEO, Peter van Oord. “We have also made large investments by adding the world’s most advanced offshore wind equipment, such as installation vessel Aeolus and cable laying vessel Nexus, to our fleet. Thanks to our dedicated people, innovative solutions and specialised equipment we can contribute in making offshore wind a common form of sustainable energy.”
Construction on the Norther Offshore Wind Farm is expected to start in 2018.
The project is expected to contribute significantly to Belgium meeting its target of generating 13% of its energy needs from renewable sources by 2020.
Dennis Sanou, Norther Project Director, commented: “Project Norther and its shareholders Elicio, Eneco and Mitsubishi Corporation are proud to conclude that after a long period of intense preparation and thanks to all parties involved we have been able to achieve financial close. We are sure that the construction and commissioning of Norther in 2018 and 2019 will be a successful endeavour with reliable and experienced partners as Van Oord.” (http://www.pic4ever.com/images/128fs318181.gif) (http://www.desismileys.com/smileys/desismileys_0293.gif)
Statoil :D Wins U.S. Offshore Wind Lease Off New York
December 16, 2016 by gCaptain
Norwegian energy giant Statoil has been declared the provisional winner of the U.S. government’s wind lease sale of 79,350 acres offshore New York.
The win will allow Statoil the opportunity to explore the potential development of an offshore wind farm to provide New York City and Long Island with a significant, long-term source of renewable electricity.
Statoil submitted a winning bid of $42,469,725 during the online offshore wind auction concluded Friday by the U.S. Department of the Interior’s Bureau of Ocean Energy Management (BOEM).
“We are excited to have submitted the most competitive bid in a highly attractive project, Statoil’s first offshore wind lease in the United States. We now look forward to working with New York’s state agencies and contribute to New York meeting its future energy needs by applying our offshore experience and engineering expertise,” says Irene Rummelhoff, Statoil´s executive vice president for New Energy Solutions.
The lease comprises an area that could potentially accommodate more than 1 GW of offshore wind, with a phased development expected to start with 400-600 MW. The New York Wind Energy Area is located 14-30 miles (30-60 km) offshore, spans 79,350 acres (321 km2), and covers water depths between 65 and 131 feet (20-40 meters).
Next Statoil will conduct studies to better understand the seabed conditions, the grid connection options and wind resources involved in the lease site.
“We will work closely with the New York State Energy Research and Development Authority (NYSERDA) on these studies and throughout the permitting process, and in connection with power offtake options,” says Rummelhoff.
The State of New York projects that offshore wind will be a significant part of the renewable energy generation needed to meet its Clean Energy Standard in 2030.
The United States’ first offshore wind farm, the Block Island Wind Farm, went live on December 12 and is expected to hit full power next month.
“The US is a key emerging market for offshore wind – both bottom-fixed and floating – with significant potential along both the east and west coasts. As today’s announcement shows, Statoil is well positioned to take part in what could be a significant build out of offshore wind in New York and other states over the next decade. This effort is in line with the company’s strategy to gradually complement our oil and gas portfolio with viable renewable energy and other low-carbon solutions,” says Rummelhoff.
In Europe, Statoil is developing an offshore wind portfolio with the capacity of providing over 1 million homes with renewable energy. Statoil currently holds a 40% share in the Sheringham Shoal wind farm in the UK, which has been in production since 2012. The Dudgeon offshore wind farm, also located offshore Norfolk in the UK – and the world’s first floating offshore wind farm, Hywind Scotland – will come in production in 2017. Earlier this year, Statoil acquired 50% of the Arkona offshore wind farm in Germany, which will come in production in 2019.
Amazon to Flip the Switch on Massive Wind Project in North Carolina
Natural Resources Defense Council
By Robynne Boyd
Before the ball drops on New Year's Eve, 104 wind turbines scattered across 22,000 acres of farmland near Elizabeth City, North Carolina, will begin churning out electricity.
It will be the South's first large-scale wind farm. At 208 megawatts, Avangrid's facility has the capacity to capture enough of the sky's kinetic energy to power 61,000 homes. But instead of homes, this electricity will run data centers for Amazon Web Services, a subsidiary of Amazon.com.
Wind generates about 5 percent of U.S. electricity, but that figure is steadily rising. In fact, at 41 percent, wind power was the largest source of new electricity production in 2015. None of that, however, came out of the Southeast. The region imports 3.8 gigawatts of wind energy from the Midwest (enough to power 10 million homes for as little as 1.8 cents per kilowatt-hour), but wind farms themselves, similar to solar, have almost no penetration here.
"Wind is so new in the Southeast; I think there has been a fear of the unknown," said Katharine Kollins, president of Southeastern Wind Coalition. "Having the Avangrid project up and running will be important for people to see wind farms firsthand and up close."
Except for the occasional hurricane, the South isn't known to be particularly windy—at least not compared with Plains states like Iowa, where the wind accounts for nearly a third of total electricity generation. But great potential exists in this void and with new turbine technology, some southern states are getting ready to tap into it.
"The biggest change in the industry has been turbine advancements," said Simon Mahan, director of the Southern Wind Energy Association, an industry organization. Taller turbines, like those at Avangrid's Amazon Wind Farm, can reach higher, stronger winds, and longer blades are able to harness gentler breezes. "This is opening the South as the next frontier for wind energy," Mahan noted.
Indeed, wind turbines have gone through a growth spurt. Since the 1990s, hub height has risen from 45 to 300 feet, which is as tall as the Statue of Liberty. And blades now extend more than 180 feet in length.
In addition to technology, improvements in energy policy, such as renewable energy standards and the federal Production Tax Credit, have enabled wind's price tag to plummet 90 percent over the past 25 years, making it more alluring in the competitive energy market.
According to a 2015 report by the U.S. Department of Energy, the Southeast could become the Most Improved Player in coming years, particularly as the national energy mix continues to change. "If I'm thinking realistic numbers, the Southeast could easily support a few gigawatts of wind," Kollins said.
Over the next 12 years, 46 coal power plants around the country (including 19 in the Southeast) are due to retire, despite the incoming Trump administration's promises to bring back the coal industry by removing regulations that protect clean air and water. Improved energy efficiency will help, but those retired plants' electricity contribution, about 15,600 megawatts, will need to be replaced with something. And that something will likely be a combo of cheap natural gas and renewables, which together provided 45 percent of the country's electricity last year.
"A company or utility looking to decrease its costs needs to be looking to buy wind and solar right now," Mahan said. "At the end of the day, if it's cheaper to do, why not?" ;D

The Long Island Power Authority approved plans for a 90 megawatt, 15-turbine wind farm off the shore of Long Island, the nation's largest project to date.
The $740 million project will begin construction in 2020, powering 50,000 homes upon completion and moving New York closer to Gov. Cuomo's goal of developing 2,400 MW of offshore wind power by 2030. At 256 square miles, the farm is large enough for the developer, Deepwater Wind, to build as many as 200 turbines in years to come.
The federal Bureau of Ocean Energy Management has awarded 11 sites for offshore wind farms, including along the coasts of Massachusetts, Delaware, and Virginia.
Agelbert NOTE: Trump hates wind turbines with his typical lack of objective reasons for this animosity. For example, he talks about bird deaths from wind "mills" (he can't seem to call them by their proper name ;)) but TOTALLY ignores the gargantuan bird deaths from OIL Refineries, Chemical Manufacturing Plants, fossil fuel power plants AND nuclear power plants. I wonder how this PUPPET of the fossil fuel industry will try to sabotage this wind project. Make no mistake, he will definitely try to sabotage it. Logic is not his thing. He is a man on a profit for the polluters mission.
Keith Olbermann thinks Trump is nuts. I think he is a megalomaniac, but I don't think he is off his rocker. That said, I agree with Olbermann that Trump's actions lately certainly have not been rational. The video aside, it is fascinating to watch the right wingers try to imagine Trump's actions as "reflecting a reasoned approach." ::) The straw grasping attempts by the right wingers to give legitimacy to that POS POTUS are pathetic. But I'm sure the "greed is good" crowd will keep trying celebrate their megalomaniac leader. (http://www.pic4ever.com/images/budo.gif) (http://www.pic4ever.com/images/245.gif)

Wind Turbines Pose No Significant Threat To Human Health (http://cliparts.co/cliparts/Big/Egq/BigEgqBMT.png)
There are no significant adverse effects to human health stemming from wind turbines, according to a study by Germany’s Federal Environment Agency (UBA).
Scientists analysed the health risks wind turbines might pose due to noise emissions (including subsonic noise), ice throw, light emissions and shadows, as well as disturbances based on subjective perception of turbines.
If turbines are operated correctly, “the health risk potential is very marginal,” the study said. Technological progress had considerably reduced detrimental impacts of turbines, making them less dangerous for human health than CO2-emitting coal plants, the UBA said.
However, it added there often were “fears and reservations among residents concerning potential health risks, in spite of clear scientific indications” that would be best countered by closely involving the public in the planning and construction of wind turbines near their homes from the start.

Greens criticise Schulz’s omission of climate protection statement
The German Green Party has criticised the Social Democrat candidate for chancellor, Martin Schulz, for not having taken a clear stance on climate protection yet, news agency dpa reports. The Green’s parliamentary group chairman Anton Hofreiter told dpa that in the current grand coalition government with Angela Merkel’s conservative CDU party, Schulz’s SPD party had slowed down the Energiewende and ignored climate protection. “I haven’t seen Schulz setting a course on this matter yet,” Hofreiter told the news wire. However, he said he regarded pro-European Schulz as an “interesting candidate” whose nomination by the SPD could “only benefit” the election battle if it motivated people to take an interest in politics.
Karlsruhe Institute of Technology
“Changed land use causes more CO2 than expected”
Forest clearance and other changes to the landscape are responsible for more CO2-emissions than previously thought, researchers at the Karlsruhe Institute of Technology (KIT) have found. “Forests, grasslands and fields contribute considerably to climate protection” by absorbing carbon dioxide from the atmosphere, KIT said in a press release. Comparing the absorbance patterns of natural and transformed landscape now suggested that vegetation’s capacity to store CO2 was even “greater than expected. [...] In any case, our results support efforts to prevent further large-scale forest clearance in order to protect the climate,” KIT added.
“Driving a car is not a fundamental right”
Driving cars might be very dear to large parts of the German population, but it is not a fundamental right and can be harmful to health and environment, writes Svenja Bergt in an opinion piece in tageszeitung (taz). Instead of half-hearted diesel bans, she proposes private car bans for inner cities. “Delivery transport, street cleaners and ambulances fill up on green power. Bicycle rentals on every other street corner. Public transport every three minutes. Parks instead of parking. Then residents in towns in valley basins could breathe freely even at times of thermal inversions,” Bergt writes.

Wind Overtakes Coal Power in Europe as Turbines Head Offshore
February 9, 2017 by Bloomberg

By Jessica Shankleman
(Bloomberg) — Wind farm developers installed more power than any other form of energy last year in Europe, helping turbines to overtake coal in terms of capacity, industry figures show.
European wind power grew 8 percent, to 153.7 gigawatts, comprising 16.7 percent of installed capacity and overtaking coal as the continent’s second-biggest potential source of energy, according to figures published Thursday by the WindEurope trade group. Gas-fired generation retained the largest share of installed capacity.
With countries seeking to curb greenhouse gas emissions that causes climate change by replacing fossil fuel plants with new forms of renewable energy, investment in wind grew to a record 27.5 billion euros ($29.3 billion) in 2016, WindEurope’s annual European Statistics report showed.
“Wind and coal are on two ends of the spectrum,” said Oliver Joy, a spokesman for WindEurope, in an e-mail. “Wind is steadily adding new capacity while coal is decommissioning far more than any technology in Europe.”
The group underscored that wind, which only produces power intermittently, hasn’t yet overtaken coal share in total power generation.
European wind investment increased 5 percent in 2016 from a year earlier driven by the offshore segment that attracted 18.2 billion euros, the report said. That offset a 29 percent investment decline in the onshore market.

Wind power (http://www.4smileys.com/smileys/seasons-smileys/storm.gif) briefly sets record as source for electricity in U.S. (http://www.createaforum.com/gallery/renewablerevolution/3-200714191258.bmp)
By Scott DiSavino
Wind briefly powered more than 50 percent of electric demand on Sunday :o (http://www.createaforum.com/gallery/renewablerevolution/3-080515182559.png) , the 14-state Southwest Power Pool (SPP) said, for the first time on any North American power grid.
SPP coordinates the flow of electricity on the high voltage power lines from Montana and North Dakota to New Mexico, Texas and Louisiana.
Wind power in the SPP region has grown significantly to over 16,000 MW currently from less than 400 megawatts in the early 2000s and is expected to continue growing. One megawatt can power about 1,000 homes.
"Ten years ago, we thought hitting even a 25 percent wind-penetration level would be extremely challenging, and any more than that would pose serious threats to reliability," SPP Vice President of Operations Bruce Rew said in a statement.
"Now we have the ability to reliably manage greater than 50 percent wind penetration. It's not even our ceiling," Rew said.
Wind power briefly reached 52.1 percent at 4:30 a.m. local time on Sunday, SPP said on Monday, beating the previous penetration milestone of 49.2 percent. Wind penetration is a measure of the amount of total load served by wind at a given time.
Currently, wind is the third biggest source of generation in the SPP region, making up about 15 percent of capacity in 2016 behind natural gas and coal. This is the first time that wind was even briefly more than 50 percent of the source of electric power at any U.S. grid, according to SPP.
"With a (generation) footprint as broad as ours, even if the wind stops blowing in the upper Great Plains, we can deploy resources waiting in the Midwest and Southwest to make up any sudden deficits," Rew said.
Of the 11 states that received more than 10 percent of their power from wind in 2015, the top five are Iowa at 31 percent, South Dakota at 25 percent, Kansas at 24 percent, Oklahoma at 18 percent and North Dakota at 18 percent, all at least partially located in the SPP grid, according to the U.S. Energy Information Administration.
Some of the biggest wind farms in the grid are operated by units of Sempra Energy, BP Plc, EDP Energias de Portugal SA, Southern Co and NextEra Energy Inc.
Shell (http://www.coh2.org/images/Smileys/huhsign.gif) ;D Looks Beyond Dutch Waters for Offshore Wind Investments
February 22, 2017 by Bloomberg
By Jessica Shankleman
(Bloomberg) — Royal Dutch Shell Plc may contract to build offshore wind farms in the U.K. and across Europe, after winning a bid to build one of the cheapest projects on record last year, Shell U.K. chair Sinead Lynch, said in an interview.
Europe’s biggest oil supplier is exploring opportunities across Europe for offshore wind, Lynch said at a press event on Wednesday at a Shell service station outside London, where she was opening the company’s first U.K. hydrogen refueling station.
Shell in December won a bid with Eneco Holding NV, Van Oord NV and a unit of Mitsubishi Corp. to build the Borssele III and IV wind farms with a combined capacity of 680 megawatts near the Dutch port city Zeeland. The power-purchase contracts to supply electricity at 5.45 euro cents (5.7 U.S. cents) a kilowatt-hour were the second-cheapest ever worldwide and slightly higher than the 4.99 euro cents a kilowatt-hour contract that Vattenfall won in September to build Denmark’s Kriegers Flak offshore wind farm.
“We are looking long and hard at how we might build a business in offshore wind,’’ she said.
Offshore wind meets Shell’s criteria for new technology investments of having scale, and being an area where it can compete “and win,’’ she said. Its experience in complex offshore project management naturally lends itself to the emerging renewable technology.
“It’s also about marketing energy so once you produce your wind you need to market the power,’’ she said.

Agelbert NOTE: If this means SHELL is moving into Renewable Energy for real, and this is not just a marketing ploy like BP's "Beyond Petroleum" head fake into solar panels, then good for them. We shall see. At any rate, anything that gives Rex Tillerson and Trump (both mortal enemies of ANY Renewable Energy) the Wind Power finger makes my day. (http://www.pic4ever.com/images/4fvfcja.gif)

Denmark just ran a day entirely on wind energy — again ;D
Mihai Andrei March 3, 2017
The transition is fully underway. If we are looking for cheap, competitive and reliable, I don’t see much alternative to wind’ says Wind Europe spokesman.
Denmark was a pioneer in developing commercial wind power during the 1970s, and today a substantial share of the wind turbines around the world are produced by Danish manufacturers. They’ve maintained that motivation through the years, as Denmark’s recent history clearly shows the country’s commitment towards renewable energy. In 2015, 42% of Denmark’s energy came from wind, and they’ve had several days in which their energy came entirely from wind — even one in which Denmark produced 140% of its energy needs from wind. Yes, they’ve recently had another one of those days.
The Scandinavian nation generated 97 gigawatt-hours (GWh) on 22nd February, and it was a great day for renewables all around the continent. That day, 18.8 per cent of the European Union’s electricity demand came from wind. Wind Europe spokesman Oliver Joy said this was yet another testament to the resilience of renewables.
“It’s very impressive but what it demonstrates is that renewable can truly be a solution to Europe’s needs,” said Mr Joy, speaking to The Independent. The trend is also spreading to other European countries. “Denmark is just the latest example that we have seen in the latest months. In 2016 we saw the UK was powered without coal for 12 and a half hours, Germany went some days on renewable, and Portugal went four straight days on renewable. It shows energy transition is underway in Europe and arguably further ahead than anywhere else in the world.” (http://www.createaforum.com/gallery/renewablerevolution/3-260116191529.png)

Those tornados will get stronger and stronger, thanks to all the free energy the trapped IR heat in our atmosphere is generating from the burning of fossil fuels. The only upside to such a turbulent atmosphere is that average wind speeds will increase all over the planet (bull market for VERY STRONGLY BUILT wind turbines (http://www.createaforum.com/gallery/renewablerevolution/3-200714191258.bmp) - and underground houses :D ). But seriously, some ships (bulk carriers and even TANKERS! :o are installing vertical roller wind turbine cylinders to save on fuel. With a lot of wind around those cylinders are a good deal in the sea AND on land where HIGH winds are the norm.
Rotor Sails under testing - they make them MUCH BIGGER than that for large ships like bulk carriers and tankers (see below).

Oil Majors Plunge Into Industry That May Hurt Fossil Fuel (http://www.emofaces.com/png/200/emoticons/fingerscrossed.png)
March 23, 2017 by Bloomberg
By Jessica Shankleman
(Bloomberg) — Big oil is starting to challenge the biggest utilities in the race to erect wind turbines at sea.
Royal Dutch Shell Plc, Statoil ASA and Eni SpA are moving into multi-billion-dollar offshore wind farms in the North Sea and beyond. They’re starting to score victories against leading power suppliers including Dong Energy A/S and Vattenfall AB in competitive auctions for power purchase contracts, which have developed a specialty in anchoring massive turbines on the seabed.
The oil companies have many reasons to move into the industry. They’ve spent decades building oil projects offshore, and that business is winding down in some areas where older fields have drained. Returns from wind farms are predictable and underpinned by government-regulated electricity prices. And fossil fuel executives want to get a piece of the clean-energy business as forecasts emerge that renewables will eat into their market.
“It is certainly an area of interest for us because there are obvious synergies with the traditional oil and gas business,” said Luca Cosentino, the vice president of energy solution at the Italian oil producer Eni, which is working with General Electric Co. on renewables. “As the oil and gas industry we know, we cannot get stuck where we are and wait for someone else to take this leap.”
Even as oil production declined in the North Sea over the last 15 years, economic activity has been buoyed by offshore windmills. The notorious winds that menaced generations of roughnecks working on oil platforms have become a boon for a new era of workers asked to install and maintain turbines anchored deep into the seabed. About $99 billion will be invested in North Sea wind projects from 2000 to 2017, according to Bloomberg New Energy Finance. A decade ago, the industry had projects only a fraction of that size.
While crude still supplies almost a third of the world’s energy, oil executives are starting to adjust to demands for cleaner fuels. Even so, emerging fossil-fuel alternatives including wind and solar power are starting to limit growth in oil demand.
Those technologies and electric cars may displace as much as 13 million barrels of oil a day from global demand by 2040, more than is currently being produced by Saudi Arabia, according to Bloomberg New Energy Finance.

Wind Power Smashes Records Worldwide
Wind power is skyrocketing across the globe.
In Scotland, wind turbines provided more than 1.2 million megawatt hours (MWh) of electricity to the National Grid in March, according to an analysis of WeatherEnergy data by WWF Scotland. To translate, that's enough renewable electricity to power 136 percent of Scottish households, or 3.3 million homes.
The figures represent an increase of 81 percent compared to the same time last year, when wind energy during March 2016 generated 684,632 MWh of electricity, The National noted.
"Given this March wasn't as windy as it has been in some previous years, this year's record output shows the importance of continuing [to] increase capacity by building new wind farms," said Lang Banks, director of WWF Scotland. "As well as helping to power our homes and businesses, wind power supports thousands of jobs and continues to play an important role in Scotland's efforts to address global climate change by avoiding millions of tonnes of carbon emissions every year."
Scotland's total electricity consumption (for homes, business and industry) for March was about 2.1 MWh, meaning that wind power provided about 58 percent of the county's electricity needs for the month.
Scotland (http://www.pic4ever.com/images/earthhug.gif) is a wind power all star, with wind turbines occasionally generating more electricity than is actually needed. This past March 17 and 19, wind turbines provided an output equivalent of 102 percent and 130 percent of each day's demand, respectively.
India is also celebrating a major wind energy milestone. According to India's ministry of new and renewable energy, the country added a record wind power capacity of 5,400 megawatts (MW) in 2016-17, vastly exceeding its initial target of 4,000 MW for the year. The previous best was 3,423 MW in 2015-16.
Of the new capacity, around 3,026 MW was added in March 2017 alone (http://www.pic4ever.com/images/computer3.gif), the Economic Times reported.
India's total wind capacity currently stands at around 32,177 MW.
PJM study quantifies wind’s value for building a reliable, resilient power system
April 4, 2017
The largest grid operator in the US just released an innovative study that quantifies the reliability of possible future energy mixes. It found that portfolios with very large amounts of wind energy, dozens of times greater than the current mix, scored among the highest for reliability and resilience.
PJM, which operates the power system across all or part of 13 Great Lakes and Mid-Atlantic states as well as the District of Columbia, has previously found large amounts of renewable energy can be reliably integrated. For example, its 2014 study found no reliability problems from obtaining 30 percent of the region’s electricity from renewable energy. That finding has been confirmed by many other studies, as well as grid operating experience in the U.S. and around the world.
PJM’s latest study shows that even more renewable energy can be reliably integrated. In many of the scenarios PJM evaluated, wind and solar energy reliably provided the majority of electricity.
It should be noted that many readers may be initially confused by the way PJM’s results are presented.
Due to the way PJM’s study accounts for capacity, wind should be multiplied by around five and solar by around 1.2 to convert the PJM scenarios into the share of energy that would be provided by those resources in a particular generation mix (see footnote 68 of the Appendix). For example, when the report discusses solar providing 20 percent of “unforced capacity,” that actually corresponds to solar providing around a quarter of all electricity generated on the PJM system.
Wind was able to go much higher, reliably providing the vast majority of PJM’s electricity in some scenarios. In fact, PJM found no maximum on the amount of wind it could accommodate, as noted on page 34 in appendix. As shown on page 28 of the report, scenarios in which wind provided nearly all of the generation on PJM’s system (15-25 percent of unforced capacity) maintain reliability at levels comparable to those on today’s power system.
Wind makes the power system more resilient
Perhaps the most innovative aspect of PJM’s study was testing the resilience of future energy mixes to extreme events like the 2014 polar vortex. As we’ve explained previously, wind performed quite well during that event, while many conventional power plants failed due to the cold weather.
Only around one-third of the reliable energy portfolios PJM analyzed passed the resiliency test. Portfolios with a large amount of wind energy tended to be more resilient because, as PJM noted, wind energy possesses the unique benefit that “unavailability rates for wind are likely to decrease” under a polar vortex event.
Said another way, wind energy output tends to be above average when extreme weather causes output from nearly all other energy sources to fall below expectations. That type of negative correlation with the availability of other energy sources is the key to using portfolio diversity to make the power system more resilient.
Interestingly, PJM’s results show wind energy contributing to resilience in a way that is comparable to the contributions of coal and nuclear power plants. PJM found wind energy played a large role in almost all of the scenarios that maintained resilience while retiring many coal and nuclear power plants. As seen in the following chart showing the portfolios that passed the resiliency test, wind steps in in almost perfect lock-step when coal and nuclear are not available. For the two-thirds of scenarios that did not pass the resiliency test (those that appear in Figure 16 of the Appendix but not below), many had much lower amounts of wind energy.
PJM’s report discusses other extreme weather events that have affected a large share of generation, but does not quantitatively analyze resilience to them. Examples include droughts that have limited conventional power plants’ access to cooling water. Droughts and sustained high temperatures in various parts of the U.S. have forced fossil and nuclear plants to operate at reduced output or even go offline, while the recent drought in California greatly reduced the state’s hydroelectric output. Wind energy and solar photovoltaics continued to generate as expected during these events, as they require no water to operate.
Wind provides grid reliability services
The report notes that technological advances enable wind energy to provide many of the reliability services that conventional power plants provide today.
In fact, in many cases wind plants exceed the ability of conventional resources to provide these reliability services. As a result, in the high renewable scenario, PJM found wind could grow to provide 25.5 percent of PJM’s flexibility needs, up from 1.3 percent today. Partially as a result, PJM found a high renewable power system was about 50 percent more flexible than today’s power system (Appendix, page 29).
However, there appear to be some flaws in PJM‘s quantification of energy sources’ reliability services contributions. (See pages 17-20 of PJM’s report for the definitions of the following reliability services) As one example, because PJM’s calculation of reactive power contribution is based on historical data, it does not account for the increased reactive capability required of new wind and solar plants under a 2016 Federal Energy Regulatory Commission order.
PJM also incorrectly de-rated wind’s reactive power capability by 87 percent, due to the capacity accounting methods discussed above, while solar’s was reduced by 62 percent. While this derating of reactive capability makes sense for conventional generators, it is inappropriate for wind and solar plants that use power electronics to provide reactive power when they are operating at partial, or even zero, real power output. As a result, new wind plants are capable of providing fast and accurate voltage and reactive power control the vast majority of the time.
Similarly, PJM’s assumptions regarding the provision of frequency regulation service are based on current operating procedures, even though those will change as the resource mix changes. For example, Xcel Energy already uses wind plants to provide frequency regulation service, and has found wind provides frequency regulation that is faster and more accurate than that provided by conventional power plants. In the Appendix PJM acknowledges that at higher penetrations wind is likely to provide the same primary frequency response contribution as conventional power plants, but the same logic would apply to frequency regulation.
In fact, wind plants will likely be better than conventional power plants at providing primary frequency response and regulation. Wind plants typically respond to frequency regulation signals an order of magnitude faster than conventional power plants can, while the North American Electric Reliability Corporation has found that around 90 percent of conventional power plants fail to provide sustained primary frequency response. PJM’s report does note that nuclear plants do not provide frequency response.
Regardless, PJM’s report found that reactive power capability in the high renewable future was essentially unchanged from today’s levels, and frequency response capability only declined by a few percent. Given that the frequency response capability of the current power system greatly exceeds the need, such a small decline is not cause for concern.
PJM’s report did not analyze resources’ ability to ride through voltage and frequency disturbances on the grid. This is a critical reliability service, as the failure of conventional generators to ride through disturbances has been implicated in many recent grid reliability events. Had PJM examined this, it would have found that wind plants, again thanks to their power electronics, far exceed the capability of conventional power plants to remain online following a disturbance.
Availability of on-site fuel was the other category in which PJM projected a power system with large amounts of renewable and natural gas generation may differ from the current power system. However, it should be noted that again PJM assumed current operating practices, even though other grid operators have already required gas generators to have dual-fuel capability and store liquid fuel onsite. PJM’s report also does not account for the potential growth of innovative resources that can provide these services, like energy storage and demand response.
It should also be noted that, while PJM runs a sensitivity to examine resilience to a polar vortex event, for the reliability analysis that underlies the report’s main conclusions it does not quantify the risk that a common mode failure will take out a significant share of conventional generation. Rather, PJM uses the industry standard but invalid assumption that conventional power plant failures are random events, with no correlation between the failure of one conventional power plant and another. As real-world reliability events like the polar vortex have shown, that assumption overstates the reliability of conventional resources by ignoring the risk that many of them will be forced offline simultaneously by correlated, common mode failures. Wind and solar resources are held to a higher standard, as the impact of weather and other correlated events on their output profile is taken into account in this and other analysis.
Regardless, electricity markets will ensure that the power system continues to have enough capacity to operate reliably. The fact that prices in PJM’s capacity market are a fraction of the cost of building a new power plant indicates that there is no need for new capacity on its system. Existing power plants are almost always the cheapest form of capacity, and there is minimal impact on emissions from maintaining existing power plants that only operate during a small number of hours to maintain system reliability. If it becomes economic to replace those existing generators with new resources like demand response, energy storage, or gas generators, the market will provide the price signal to do so.
PJM’s study did examine the geographic diversity of wind and solar resources across PJM, which helps to increase the contribution of those resources to meeting capacity needs because if renewable energy is unavailable in one area it is typically available somewhere else on the power system. PJM’s study also captured the synergy between wind and solar output profiles, which makes their combined capacity contribution greater than the sum of its parts.
PJM’s report makes important contributions to understanding power system reliability and resilience, and confirms that very high levels of renewable energy can be reliably integrated. However, at times the report falls into the common misconception that conventional power plants provide essential reliability services while renewable resources do not. In reality, wind plants exceed the reliability contributions of conventional power plants in many cases.
And for those who think that wind power requires high-tech:
if you haven't read the true history of how the windmills all over the Midwest were deliberately NOT allowed to be used for generating electricity, I suggest you check it out. Farmers used them to mill grains, of course. They used them to pump water and to run lathes and other rotary tool devices to make furniture and wagon parts.
I refuse to believe these resourceful folks didn't try to run a generator from a windmill. The power people just didn't want distributed renewable energy out there competing with their centralized electrical juice business model, so they did what they could to prevent that.

A divide (http://www.pic4ever.com/images/3ztzsjm.gif) (http://www.createaforum.com/gallery/renewablerevolution/3-200714191258.bmp) emerges among North Carolina Republicans on wind energy
Written By Elizabeth Ouzts
April 18, 2017
A small band of North Carolina GOP legislators has made its antipathy toward wind power clear in recent months – urging the Trump administration to shut down the state’s first major wind farm and introducing two different bills to severely restrict future projects.
But this week a set of state House Republicans will push legislation designed to help wind power rather than hurt it.
“The only thing my bill has in common with the other two, is that it does deal with wind energy,” said Rep. John Szoka (R-Cumberland), the lead sponsor of House Bill 574 along with Reps. Holly Grange (R-New Hanover) and Sam Watford (R-Davidson). “The similarities probably stop there.”
The legislation streamlines the state’s permitting process, but allows the Department of Military and Veterans Affairs to reject any new wind farm proposal – a response to concerns that wind turbines could threaten eastern North Carolina’s military bases.
“I’m not trying to put more restrictions on wind developers,” said Szoka, a retired U.S. Army officer whose Fayetteville district includes Fort Bragg. “I’m trying to put to rest some of the fears.”
Cosponsored by a bipartisan group of 18 representatives, the proposal will get a hearing Wednesday in the House energy committee, which Szoka chairs.
Backers of the bill are optimistic it will carry more support than the anti-wind proposals, which they say come from a small but vocal minority.
“In our experience, most lawmakers are looking for ways to have the right balance,” said Greg Andeck of Audubon North Carolina. “They care deeply about the military, they care deeply about our wildlife and natural resources, and they’re looking for the right way to grow the [wind] industry.”
‘Muddying the waters for wind energy projects’
The zeal of some lawmakers (http://www.createaforum.com/gallery/renewablerevolution/3-311013200859.png) to ban wind power has distracted from what many say are burdens of the state’s existing rules, enacted in 2013 after Republicans swept the governor’s office and the legislature.
No wind farm has been authorized yet under the standards, which were adopted after Amazon Wind Farm U.S. East, the 104-turbine project near Elizabeth City, had already won key approvals.
Critics say the permitting criteria are redundant, and vague enough to allow any wind project to be rejected or delayed by the state’s Department of Environmental Quality (DEQ).
The new law “had the effect of muddying the water for wind energy projects,” said Craig Poff of Avangrid Renewables, the Amazon wind farm’s developer, at a recent Chapel Hill conference. Though several wind power companies were eyeing the state prior to 2013, he said, “many of those big developers soon took their business elsewhere.” :P (http://www.createaforum.com/gallery/renewablerevolution/3-200714183312.bmp)
House Bill 574 is an attempt to woo that business back. (http://cliparts.co/cliparts/Big/Egq/BigEgqBMT.png) It strikes several conditions already covered in typical county ordinances, including requirements about noise, light, and the notification of project neighbors.
The legislation removes seemingly subjective criteria, such as wind farms not creating a “significant adverse impact” ;) on views from public and some private lands, while retaining standards for the protection of ecologically sensitive areas and wildlife.
Though DEQ Secretary Michael Regan under Gov. Roy Cooper is more sympathetic to wind power than his predecessor, advocates remain concerned about a provision of the law that could allow regulators to stall a permit application indefinitely. House Bill 574 removes that loophole.
“It’s less risky than what we have now,” Katharine Kollins, president of the Southeastern Wind Coalition, said of the proposal. “Right now, it’s all in the hands of DEQ under very uncertain criteria. This firms up the criteria.”
“It keeps a lot of the same protections for natural resources and wildlife,” said Audubon’s Andeck, “and at the same time, provides [wind developers] with even greater clarity on the steps and the timetable they have to follow if they want to secure project approval.”
The ‘right way’ to transition to clean energy
Audubon’s support for the bill is not insignificant. While numerous studies show that buildings and house cats cause more bird deaths than wind power, “bird blenders” ::) remains a common insult for wind turbines among skeptics (http://www.createaforum.com/gallery/renewablerevolution/3-311013200859.png) in the legislature.
But Audubon, which opened a North Carolina office in 1902, views advancing renewable energy to slow climate change as essential to its mission. Decades worth of data collected by his organization, Andeck says, shows North Carolina birds such as the brown pelican, wild turkey, and osprey already being impacted by a warming planet.
“A transition to clean energy is really critical to protect birds from the worst effects of climate pollution,” said Andeck. “That transition can be done in a right way.”
For Audubon, that means situating wind farms to avoid migratory pathways and other important bird areas rather than banning them altogether.
“Audubon has and will continue to oppose wind projects that we believe are poorly planned or sited in the state,” said Andeck. “It’s far more appropriate to look at projects on a case by case basis, rather than make broad claims about the impacts of a technology on wildlife.”
‘Trying to find a happy medium’
Much louder than their complaints about wildlife, however, are protests from some lawmakers about wind power’s impact on the military – a $66 billion economic engine concentrated in eastern North Carolina.
Critics claim the Amazon wind farm will interfere with a Navy radar in Virginia. They say base commanders and others have been bullied into agreeing to nearby wind farms. And they argue the U.S. Department of Defense could easily choose to relocate military bases to other states if wind farms became an imposition.
“If you want to decimate a state, you pull out the military,” said Rep. John Bell (R-Wayne), the House majority leader and cosponsor of a bill to place a moratorium on new wind farms until 2020.
Szoka doesn’t see wind farms and military as incompatible. He visited the Navy radar site said to be threatened by the Amazon wind farm. “I’m thoroughly convinced that it’s just fine,” he said.
But his bill tries to address his colleagues’ concerns by involving the state’s Department of Military and Veterans Affairs from the beginning, and requiring any new wind farm to receive a letter of approval from the department’s secretary.
That additional power is no small concession for wind power developers, who have long maintained that the current system for military approval works well, and involves local base commanders up front.
“There have been precisely zero projects that were built over the objection of military personnel,” said Dave Belote, a former military official who now consults with wind developer Apex Energy.
Belote created the federal process by which the military approves wind power projects. “As a former base commander, I ensured that the base commander has the ultimate say,” he said.
Charlottesville, Virginia-based Apex has approval from Chowan County for its 105-turbine Timbermill Wind project, and is appealing a denial from Perquimans County. It will apply for state approval once the county process runs its course.
The company, whose project would be just eight miles from the Amazon Wind farm and could become the state’s largest, has so far remained mum on House Bill 574.
But backers of the bill, which must clear a second committee and the full House by April 27 to meet a key legislative deadline, say it should satisfy concerns from both wind proponents and critics.
“Politics are the art of compromise. We were trying to find a happy medium here,” said Szoka. “My job isn’t to protect any particular industry, it’s to look out for the betterment of the state overall. I think that this bill does that.”

Yeah, we hunt and eat birds. So what!? More birds are killed from hitting glass windows on BUILDINGS than from our natural predatory habits. And furthermore, gas and coal power plants kill a LOT MORE birds than wind turbines ever will. So there! PFFFFT!
Just wait till that fossil fueler tries to pet me after blaming me, my pals and wind turbines for all those dead birds his polluting power plants, cars and stupid buildings kill.
Denmark, Germany and the Netherlands Want to Build an Island Hub to Support 100GW of Offshore Wind (http://www.createaforum.com/gallery/renewablerevolution/3-080515182559.png)
The island could also become a crucial provider of renewable-power-to-gas for Europe.

March 22, 2017
A group of European countries is looking to build a giant island in the North Sea in order to support up to 100 gigawatts of offshore wind projects.
If built, the island would be sited on the Dogger Bank, a large North Sea sandbank where the water depth ranges from 15 to 36 meters.
It is intended to act as a staging post for turbine operations and maintenance crews, as well as to provide a central connection for planned far-shore wind farms and host direct current lines acting as interconnectors between Denmark, Germany, Holland, Norway and the U.K.
“The cooperation will spend the coming years investigating feasibility and develop a model before deciding whether to go forward,” said Jesper Nørskov Rasmussen, press officer at Energinet.dk, the Danish transmission system operator (TSO).
The island might feature power-to-gas as a storage technique to utilize high volumes of wind generation, said Rasmussen. The North Sea is home to a sophisticated network of gas pipelines, which could help bring wind-generated gas to countries around Europe.
Denmark to End All Renewable Energy Subsidies (http://www.pic4ever.com/images/za4.gif)
April 27, 2017
By Peter Levring, Bloomberg renewable energy
After more than four decades of relying on subsidies, Denmark’s renewable energy industry is ready to survive on its own much sooner than anyone expected. (http://www.createaforum.com/gallery/renewablerevolution/3-200714191258.bmp)
The Danish energy minister, Lars Christian Lilleholt, says that “in just a few years,” renewable energy providers won’t need state support anymore. He says it’s a development he couldn’t have imagined as recently as last year.
“We’re now very close to arriving,” he said in an interview in Copenhagen on Monday, after receiving a set of recommendations from a government-appointed panel on Denmark’s energy future.
The development marks a milestone. But it also comes at a time when the direction of global energy policies is in doubt, with U.S. President Donald Trump questioning the science behind global warming. He’s promised to revive America’s coal industry, and made clear he’s an enemy of wind power.
Lilleholt says the experience in Denmark — home to Vestas Wind Systems A/S (the world’s biggest wind-turbine maker) and Dong Energy A/S (the world’s biggest offshore wind park operator) — demonstrates that coal is no longer cheaper to produce than renewable energy.
What’s more, the development is set to become more pronounced, Lilleholt says. “Everything suggests that technology will help make renewable energy more and more competitive,” he said. And as green energy becomes more efficient, the minister warns that “already today, it’s impossible to build a new coal power plant without support.”
Denmark is on target to have all its energy needs covered by renewables by 2050, with half that goal set to be achieved in 2030, the panel said. Much of the new capacity will be built without subsidies, according to the panel. It recommended all energy consumption, including heating and transportation, be shifted to electricity generated by renewable energy.
Industry members are also surprised at the pace of the shift. Niels B. Christiansen, the outgoing chief executive officer of Danfoss A/S (an engineering firm that provides heaters and coolers) says he expects the cost of producing renewable energy to drop below market electricity prices at some point between 2020 and 2030.
“A year ago, it was debatable whether renewable energy costs could drop so low,” he said in an interview. “But everyone’s now thinking that it will probably happen sooner.”
