Apple Opens Solar Spaceship Headquarters in April, Amazon Also Expands Renewables

After four years of construction, 12,000 employees start moving into Apple’s new spaceship campus in April. Now called Apple Park, the 175-acre campus near Cupertino, California will be a model for energy efficiency and 100% powered by renewable energy.

The building’s circumference hosts one of the largest on-site solar systems in the world – a massive 17 megawatts (MW) of solar panels!  :o   That will supply 75% of the electricity; the rest comes from buying half the output of a nearby 280 MW solar farm and 4 MW of on-site fuel cells. As the world’s largest naturally ventilated building, it will require No heat or air conditioning for nine months of the year  ;D. Almost all of the materials from demolishing previous buildings at the site has been reused or recycled – virtually every piece of concrete, glass, and metal.

Apple spaceship

Worldwide, 93% of Apple’s power for offices and retail comes from renewable energy, and 100% of power for data centers.  The next step is manufacturing – the source of 77% of its greenhouse gases. A 170 MW solar farm in Mongolia will begin powering China’s factories and a supplier in Japan is building 20 solar plants including one of the largest floating solar systems. In tandem with suppliers, over 4 gigawatts (GW) of renewables will be added around the world by 2020, including 2 GW in China.

“We’re switching to greener materials to create safer products and manufacturing processes. We’re protecting working forests and making sure they are managed sustainably. We’re even creating a more mindful way to recycle our devices using robots,” Apple says on its Environment page.

Amazon Steps Up

Amazon.com also made a big announcement – over the next three years, it will put solar on the roofs of 50 warehouses around the world. Solar will provide as much as 80% of power at sites in California, Nevada, New Jersey, Maryland, and Delaware, starting this year. The company is building the 253 MW Amazon Wind Farm Texas and a 180 MW wind farm in Ohio, adding to its wind farms in Indiana and North Carolina.

“We are putting our scale and inventive culture to work on sustainability. By diversifying our energy portfolio, we can keep business costs low and pass along further savings to customers. It’s a win-win,” says Dave Clark, senior vice president of worldwide operations.

Last year, Amazon, Apple, Google, and Microsoft filed an amicus brief in support of the EPA’s Clean Power Plan, now under attack by the Trump Administration.

Recent Advancements in the Solar and Renewable Energy Industry

By Daphne Stanford on March 22, 2017 at 15:33 pm   

It’s 2017, but solar cells went into commercial production in 1953, so you do the math: we should probably have access to affordable solar power, by now, but there are numerous dirty fuel proponents working to try to ensure that we continue to be dependent upon them for as long as possible.  However, despite the slow progress, exciting technological breakthroughs are being discovered that should make affordable solar power available to the average consumer sooner rather than later.

Most of us are at least somewhat familiar with how solar energy is generated: first, solar panels collect sunlight; next, power is converted into usable electricity; next, electricity flows into the net meter; and finally, the attached building is able to use the electricity produced by the sun.  In order for solar power to become more widely utilized, it has to become more affordable.  However, National Geographic reports that significant advances in nanotechnology will soon lead to lower costs and higher efficiency rates. 

What kind of advancements, specifically, you ask?  To cite one example, researchers from MIT and the Masdar Institute of Science and Technology have developed a new solar cell—what they’re calling a “step cell”—that combines two different layers of sunlight-absorbing material to harvest a broader range of the sun’s energy.

There was also a new development just this month, as reported in Science Daily:

Researchers at The City College of New York-based CUNY Energy Institute announce the development of a novel low cost, rechargeable, high energy density battery that makes the widespread use of solar and wind power possible in the future.   

Think Tesla’s Powerwall, only more affordable.  Moreover, Green Tech Media recently compared the costs of wind and solar to gas, coal, and nuclear-based energy, illustrating the clear advantage that renewable energy has over fossil fuels, price-wise.  Why are our cities’ and towns’ energy grids so slow to implement clean energy sources?  Michael O’Boyle cites two widespread misconceptions: first, “Misguided alarmism about the reliability of renewables,” and second, “Misconceptions of the cost of running the grid with more renewables.”

The potential cost of implementing solar power into energy grids is even lower due to increased loans to solar energy production companies, so there’s that, too.  All in all, the costs of solar energy are going down—no matter how much the Trump administration would like us to believe in its inconvenience and unaffordability.  Moreover, there has been considerable progress in the renewable energy world in terms of new career opportunities unique to the industry, more affordable consumer options, and new technological advancements.

Over the past year, there have been a number of new technologies developed related to solar efficiency, solar energy storage, wearable solar technology, and solar design tech.   Perhaps one of the most exciting developments that has received a good deal of attention is solar roadways: they are roads with the ability to convert sunlight into energy to be delivered to local smart grids.  According to their website, “Our goal is to modernize the infrastructure with modular, intelligent panels, while producing clean renewable energy for homes and businesses.”

Beyond specific products, there are also a number of careers in sustainability-related fields like forestry and geology that should be attractive to those interested in supporting the renewable energy industry.  A common role for a forestry graduate, for example, is that of a conservation scientist or forester.  Companies typically create this position in order to help them manage their use of forests as resources related to their product supply chain.  Georgia-Pacific, for example, attempts to replenish and responsibly preserve the forest elements that they harvest for business use.

Other related fields, such as geography and geology, offer career opportunities in cartography or geoscience.  The advantage of these nature-related jobs is the sense of purpose that they offer to the potential employee in search of ethical work.  Many people these days, faced with dire news about the state of the environment and climate change around the world, are beginning to feel compelled to search for more meaningful job positions that help to improve people’s lives in some way. 

Because of this new awareness of the importance of sustainability, moreover, it’s not as necessary as it used to be to enter the not-for-profit world in order to find meaningful work.  Many small and medium-sized companies—even larger corporations—are becoming more aware of their corporate social responsibility (CSR) policies and developing more substantial ethical compasses that offer more satisfaction to the socially-conscious job seeker.  More and more people are asking, “Is the world a better, safer, or healthier place because of my company?”  And an increasing number of companies are confidently responding with a resounding, “Yes!” 

More people, also, are becoming increasingly aware of the importance of personal responsibility, when it comes to sustainable living and eco-friendly lifestyles.  There are a number of simple, tangible actions that you, personally, can take at home in order to maximize your energy efficiency and long-term monthly expenses, as well.  For example, you’ll be able to save a substantial amount of money just by getting rid of wasteful, out-of-date appliances. 

Conducting a home energy audit requires little energy on your part after you make a call to a local certified energy rater or auditor.  An auditor will be able to determine the areas in your home that need additional insulation and weatherization.  You can also make sure that your appliances and lightbulbs are up to date, in terms of the most energy-efficient models and light sources—if in doubt, look for the “Energy Star” symbol on products when searching for replacements.  Lastly, be mindful of your water usage and the amount of food waste you throw out; the simple act of composting can relieve much of the burden on our local landfills.

*   *   *

Living in a sustainable manner requires all of us working together to ensure we’re picking the most socially and environmentally responsible options—whether it be an appliance, a job position, or a political vote supporting renewable, energy-efficient policies and legislation in favor of clean energy.  What are you doing to contribute to a more sustainable world?

First Utility-Scale Project on Tribal Lands to Power 100,000 Homes
Mar. 21, 2017 01:57PM EST

By Dan Whitten

First Solar held a commissioning event last week on a 250-megawatt solar facility on the Moapa River Indian Reservation. This is the first utility-scale solar project on tribal lands.

Morgan Stanley put together this cool video on the project as part of their series on sustainable solutions called Capital Creates Change and we wanted to share it with you. It highlights the economic opportunity, the jobs and the clean power that utility scale developers are bringing to Indian Country and to Southern Nevada.

Late last year, I was lucky enough to attend a ribbon cutting at NextEra Energy's Silver State South project, a 250-megawatt project developed and built by First Solar at the southern tip of Nevada, on the California border line. Eight years ago, when developers began surveying the Silver State South site, they couldn't have known what the world or even that little corner of the Nevada and California border would look like in terms of solar adoption. But they did know major change was afoot.


Back then, solar accounted for one hundredth of one percent of the nation's power generation and it was considered by some to be the costliest form of electricity.

In hindsight, the project goes a long way toward explaining the phenomena we are seeing in solar energy today. First off, the region now boasts 1,200 megawatts of solar electricity, which is the size of two big coal plants and no emissions, a fact that helps explain why our greenhouse gas emissions as a nation are lower than they have been in more than two decades.

The Moapa Southern Paiute Solar project continues a trend in Nevada that has seen utility scale grow by leaps and bounds and with it has come thousands of jobs. Economies of scale evident from solar adoption help explain why the cost of solar has dropped by about 70 percent in the last eight years.

And while the utility scale revolution is taking hold in the West, policies governing rooftop solar in Nevada have crippled that segment of our industry and the many benefits that a healthy distributed generation market can provide for our electrical grid. The model is in place for many thousands of megawatts of clean electricity in the West and the hundreds and thousands of jobs that come with it.

The key is making sure there is a welcoming policy environment for continued growth of large scale solar, with triggers that can help distributed solar take pressure off the grid.

World's Biggest Solar + Battery Farm  Coming to Australia

By Lorraine Chow

30 March, 2017

A massive solar and battery farm is being built in South Australia's Riverland region.

If everything goes to plan, the plant will be running by the end of 2017 and will be the largest such system in the world, Brisbane-based renewable energy developer and investor Lyon Group announced.

The Riverland plant consists of 330MW of solar PV and a 100MW/400MWh battery storage system, or 3.4 million solar panels and 1.1 million batteries.  :o  ;D

The new project couldn't come sooner. A major gas shortage is looming and the country's decades-old coal plants are shutting down, sparking potential price hikes and putting the nation's energy security at risk.

The $1 billion (US $767 million) project was announced amid South Australia's recent spate of blackouts.

Interestingly, the ball really seemed to roll after an intriguing tweet from none other than Elon Musk.

You may recall that earlier this month the Tesla CEO offered to build a 100MW battery storage farm for the Australian state. To up the ante, he said he would provide the system for free if it was not commissioned within 100 days. Musk's audacious bet led to an eventual conversation with Australian prime minister Malcolm Turnbull.

Days later, the South Australian government announced an open, competitive tender for a 100MW battery storage project.

"The battery will modernize South Australia's energy grid and begin the transformation to the next generation of renewable-energy storage technologies," the government office stated.

According to Australia's ABC News, Lyon Group partner David Green said the company will build its new plant, along with a similar plant near the town of Roxby Downs, regardless of the outcome of the government's tender: 

The Lyon Group has already signaled its intention to bid for a SA government tender to build a battery storage system with 100-megawatt output.

The tender arrangement would give the government the right to tap the battery storage at times of peak demand, but allow the project owner to sell energy and stability into the market at other times.

An expressions of interest process closes on Friday.

Other companies, including Carnegie, Zen Energy and Tesla, have all suggested they could be interested in bidding.

Green said the outcome of the tender would not determine whether or not Lyon's projects were built, but would influence the final storage configuration in terms of the balance between optimizing grid security and capturing trading revenue.

Green said the project was 100 percent equity financed and construction would begin within months, requiring 270 workers, ABC News reported.

"We see the inevitability of the need to have large-scale solar and integrated batteries as part of any move to decarbonize," Green added.

Germany's Merkel Encourages Spain, Portugal to Invest in Solar 

by Naomi Kresge

‎April‎ ‎8‎, ‎2017‎ ‎5‎:‎07‎ ‎AM

German Chancellor Angela Merkel encouraged Spain and Portugal to invest more in solar energy and said they need a better link to France amid a push for a unified European power grid.

“The connection between France and the Iberian peninsula is a huge problem,” Merkel said Saturday in her weekly podcast. “These are, for example, two countries in which solar power naturally could be expanded.”

Merkel’s government has promoted wind and solar energy as the country prepares for the closure of its last nuclear power stations in 2022, transforming the country’s power markets. Green output met 29 percent of Germany’s electricity demand last year, about the same as in 2015, but far exceeding the 11 percent level of a decade earlier.

The European Union is aiming to break down national barriers for power, which could make supplies more secure and lower costs thanks to more trade across national borders.

'In March, during the hours of 8am to 2pm, system average hourly prices were frequently at or below $0 per megawatt-hour'
Surfer Cole Clisby rides his surfboard off the top of a wave as the sun sets off the shores of Leucadia, California

"Yeah, they're out there havin' fun, In the warm California sun," sang The Rivieras in their 1964 hit.

And it could not be more apt today as the sun in the state was so strong – and the number of solar farms so large – that electricity prices in the state have begun turning negative on the main power exchange, the US Energy Information Administration (EIA) has revealed.

Solar made up a record figure of nearly 40 per cent of the electricity sent to the grid in the California Independent System Operator’s (CAISO’s) territory for a few hours on 11 March, after utility-scale solar farms grew by almost 50 per cent in 2016, the EIA said on its website.

However, as the Quartz website pointed out, negative wholesale prices do not translate into an unexpected windfall for consumers.

This is because retail prices are based on the average cost, so people might get slightly cheaper electricity but not an actual cash payment as a result of prices becoming negative for a few hours.

The EIA said: “The large and growing amount of solar generation has occasionally driven power prices on the CAISO power exchange during late winter and early spring daylight hours to very low, and sometimes negative, prices.

“However, consumers in California continue to pay average retail electricity prices that are among the highest in the nation.”

Solar capacity in the state has grown rapidly in the last few years.

There was less than one gigawatt in 2007, but nearly 14GW by the end of last year.

At this time of year, the large amounts of sunlight and the relatively low demand can produce too much electricity around the middle of the day.

“Electricity demand in California tends to peak during the summer months,” the EIA said.

“However, in late winter and early spring, demand is at its annual minimum, but solar output, while not at its highest, is increasing as the days grow longer and the sun gets higher in the sky.

“Although the sun is at a similar angle in September and October, electricity demand is still relatively high, leading to lower solar generation shares than seen in March.

“Consequently, power prices … were substantially lower in March compared with other times of the year or even March of last year.

“In March, during the hours of 8am to 2pm, system average hourly prices were frequently at or below $0 per megawatthour.

Albuquerque city buildings getting $25M in solar panels

Posted on Sunday, April 16th, 2017 By The Associated Press

ALBUQUERQUE, N.M. (AP) — New Mexico's most populous city has plans to install more than $25 million in solar panels on city buildings over the next two years.

The installations in Albuquerque will mark the first phase in fulfilling a recently set goal of generating more of the city's energy from solar power.

Albuquerque City Councilors Pat Davis and Isaac Benton made the announcement Saturday.

They say the project's first phase of the project is expected to save taxpayers about $20 million over 30 years.

City councilors last September passed a resolution calling Albuquerque to generate one quarter of its energy from solar power by 2025.

The first phase of the project will begin later this year.

The project will be financed through the energy savings and federal bond credits.

Do they mean 25% of their electric energy or 25% of total energy?

Spend 25 mill to save 20 mill? Isn't that a net loss of 5 mill?


 ::)

They are talking about ELECTRICAL ENERGY DEMAND from buildings, light poles, pumping stations, etc.. The city gets their JUICE from a lot of fossil fuel sources now. THAT is what they will reduce. City vehicles aren't in the equation.

AS to your math skills, I see economics isn't your thing. IF they DO NOT spend the $25 million bucks on PV, they HAVE TO SPEND X AMOUNT in electrical energy costs powered by fossil fuels.

THAT "X" amount is projected to be 20 million dollars MORE than they will spend in 30 years with the added PV. Assuming that the PV will (MTBF) crap out in 30 years, or sooner, is probably the reason you came up with the 5 million dollar "loss". There is a bit more too it than that.

The cost savings from NOT adding energy generation capacity from fossil fuels represents additional money (and health) savings not obvious to the casual observer that the city, since they are not a utility, isn't accounting for.

You may claim that building gas or coal fired power plants is cheaper than building solar panel infrastructure of equivalent capacity, but MAINTAINING fossil fuel power plants is FAR more costly than maintaining renewable energy infrastructure. SO, the more renewable energy infrastructure, the lower your operating costs.

In addition, there will be less pollution from the power supplied to the  grid, which will lower city costs in health related expenses THAT YOU ARE NOT INTERESTED IN POSITIVELY ACCOUNTNG FOR EITHER.

Finally, the cost of solar energy is a known quantity, whereas the cost of fossil fuels in the future is sure to go UP. As the city gets more and more renewable energy the savings will continue to grow for all those reasons. There will be NO price shocks, PERIOD. The more power the city can make on it's own, the less it is forced to pay higher rates to a power corporation. The only people this is a "bad deal" for are the stockholders of corporations owning fossil fuel powered power plants. 

Since you think it's a "bad deal" to lower the city carbon pollution with $25 million bucks, I guess you voted for Trump. IOW, long term cost benefit analysis is not your thing. They will save a lot more than the conservative $20 million dollars they are estimating. And even if they didn't, the improved air quality would be worth it.

 Edpell, you are a one trick, Renewable Energy attacking, pony.

You are also boring.  Go do something productive for a change.

Fractal-etched graphene electrode boosts solar energy supercapacitor storage by 3,000%

Tibi Puiu April 17, 2017

nspired by the fractal structure of the fern leaf, researchers used lasers to etch self-replicating structures on a graphene electrode, designing a novel supercapacitor. The resulting energy storage system has a 30-fold higher energy density than anything previously demonstrated and could dramatically improve solar energy applications, especially the thin solar film variety.

The breakthrough electrode prototype (right) can be combined with a solar cell (left) for on-chip energy harvesting and storage. Credit: RMIT.

There are a number of options for storing energy beyond the batteries everyone’s familiar with. For instance, a capacitor stores energy by means of a static charge, as opposed to an electrochemical reaction found in a lithium-ion battery. There are three main types of capacitors, among them the supercapacitor, which, as the name implies, has a much higher capacitance up to thousands of times higher than a classic capacitor. These are great for storing frequent charge and discharge cycles at high current and short duration. Sounds familiar? Well, solar energy is very much like that which is why there’s a great interest in the industry for supercapacitors. The reason why you don’t seem them beyond the lab included in solar energy systems is because supercapacitors were limited by energy storage densities in the order of 3 × 10−3 Whcm−3 or lower.

Australian researchers from the RMIT University in Melbourne may have set the stage for mainstream capacitors for solar energy storage. With a little help from nature, they managed to design a new electrode which when integrated with existing supercapacitors can improve the state of the art supercapacitor-based solar energy storage by an astonishing 3,000 percent.

Their inspiration was the western sword fern (Polystichum munitum) whose leaves are densely packed with veins which efficiently store energy and transport water. It’s one of the most abundant ferns in the world, known for its bright green, tapered, 2- to 3-foot-long (61- to 91-centimeter) fronds. What many gardeners might not realize about the sword fern is that at the nanolevel its leaves have a self-replicating structure akin to that of the snowflake or other fractal-like structures commonly found in nature.

A western swordfern leaf magnified 400 times. The veins of the leaf have a self-replicating structure similar to the snowflake. Credit: RMIT.

The electrode designed by the Australian researchers is based on the fern’s naturally-efficient fractal structure. To mimic the fractals, the researchers fired high precision laser pulses to manipulate sheets of graphene, the wonder material that among its many useful properties is also an excellent electrical conductor.

Tests suggest that when the novel electrode was combined with supercapacitors, the system stored charge for longer, with minimal leakage.
Quote

“The most exciting possibility is using this electrode with a solar cell, to provide a total on-chip energy harvesting and storage solution,” said PhD researcher Litty Thekkekara and lead author of the new study published in Scientific Reports.

Specifically, the greatest boost might lie in exploiting this new electrode in conjunction with thin film solar cells which are flexible enough to be used almost anywhere to capture energy from the sun, be it on windows, smartphones or watches. We might not need to charge phones via batteries using such a technology.

Quote
“With this flexible electrode prototype we’ve solved the storage part of the challenge, as well as shown how they can work with solar cells without affecting performance. Now the focus needs to be on flexible solar energy, so we can work towards achieving our vision of fully solar-reliant, self-powering electronics,”
the researchers wrote.

20,000 Pakistani Schools to Go Solar   

ByLorraine Chow

17 April

About 20,000 schools in the province of Punjab in Pakistan will convert to solar power, according to government officials.
The project will kick off in Southern Punjab schools and expand in phases across the province, according to a local report.

The Asian Development Bank and France's AFD Bank are backing the program, Cleantechnica reported. This is the first program of its kind in the country.

In Pakistan, nearly half of all residents are not connected to the national grid. Residents who are connected to the grid regularly experience rolling blackouts and power outages. And the problem is only expected to get worse in the coming years.

Renewable resources can help mitigate this growing energy crisis. Pakistan happens to be rich in solar, as the Express Tribune described:

"With eight to nine hours of sunshine per day, the climatic conditions in Pakistan are ideal for solar power generation. According to studies, Pakistan has 2.9 million megawatts of solar energy potential besides photovoltaic opportunities.


"According to figures provided by FAKT, Pakistan spends about $12 billion annually on the import of crude oil. Of this, 70 percent oil is used in generating power, which currently costs us Rs18 per unit. Shifting to solar energy can help reduce electricity costs down to Rs 6-8 per unit."

Solar energy has made great strides in Pakistan in recent years. In February 2016, its parliament became the first national assembly in the world to be powered entirely by solar energy. The legislative body, known as the Majlis-e-Shoora, is in the capital city of Islamabad.

One of the world's largest solar farms is currently under construction in Punjab. Developers of the 1,000-megawatt Quaid-i-Azam Solar Park in Bahawalpur have already added hundreds of megawatts of energy to the national grid.

Tesla unveils sleek, barely noticeable solar panels

Tesla unveiled its solar roof tiles last fall with major fanfare and for good reason. The energy-generating roof tiles could make an entire roof a power station while also looking beautiful at the same time.

The only downside was that the solar roof tiles were only attainable for people who were building a new home or installing a whole new roof. Homeowners wanting a way to add good-looking solar energy to just a section of their roof were out of luck unless they wanted to undertake some heavy renovations.

Until now.

Tesla quietly updated their website this past weekend to reveal an addition to their solar power portfolio: sleek, low-profile solar panels that can be added to any existing roof. The solar panels will be made by Panasonic at Tesla's Gigafactory 2 in Buffalo, New York exclusively for Tesla. The solar panels are made to integrate with the company's Powerwall energy storage units for a round-the-clock clean energy supply.

The 325-watt solar panels have no visible mounting hardware and an integrated front skirt to make the panels as camouflaged and streamlined as possible. Tesla claims that these panels also exceed industry standards for durability and lifespan. Elecktrek reports that the non-exclusive 325-watt module that Panasonic has on the market has an efficiency rate of 21.67% and these new panels are likely similar.

Tesla will start producing the solar panels this summer and will begin using them exclusively for all residential solar installations going forward in replacement of any other third party solar panels. While production hasn't started yet, and there's no information yet on pricing, you can already request a custom quote for your home on the website.
