100% Renewable Electricity Worldwide Is A New Cost-Effective 🌟 Reality

February 16th, 2018 by The Beam

By Hans-Josef Fell, Energy Watch Group, and Prof. Dr. Christian Breyer, Lappeenranta University of Technology

Last year, Costa Rica beat its own record. The Central American country ran 300 days on electricity generated solely from renewable energy. Following the steps of Norway and Iceland, Costa Rica is about to showcase to the world how an emerging country can succeed in transitioning to a fossil-free electricity system.

Renewable energy is increasingly a success story in emerging and developing markets. Last year, they were leading in green energy investments. China will have added around 54 gigawatts (GW) of solar PV capacity in 2017  —  three times more than any other country has ever done, which tops China’s total amount to 120 GW of solar PV installed capacity. India is catching up too, as its government announced it would tender enough renewable energy projects to surpass 200 GW of new green capacity by 2022. According to financial analysts, by 2020 renewables will have become the cheapest form of power generation.

A global power system fully based on renewable energy is no longer a long-term vision, but a tangible reality. Yet critics of renewable energy and fossil fuels, as well as nuclear lobbyists, often use solar and wind fluctuations as their major argument to hold on to the old system.

A new groundbreaking study by the Lappeenranta University of Technology (LUT) and the Energy Watch Group (EWG) refutes this argument once and for all.

The first of its kind study* simulates a global electricity system based entirely on renewable energy on an hourly basis throughout a whole year. Its results prove that the existing renewable energy potential and technologies, including storage, are able to generate sufficient and secure power supply worldwide by 2050. Under favorable political conditions, a full decarbonization and nuclear phase-out of the global electricity system can succeed even earlier than that.

The study proves that 100% renewable electricity is more cost effective than the existing system, which is largely based on fossil fuels and nuclear energy. Total levelized cost of electricity (LCOE) on a global average for 100% renewable electricity will decline to 52 €/MWh (megawatt-hour) by 2050 (including curtailment, storage and some grid costs), compared to 70 €/MWh in 2015.

Due to rapidly falling costs, solar PV and battery storage will increasingly drive most of the electricity system, with solar PV reaching some 69%, wind energy 18%, hydropower 8% and bioenergy 2% of the total electricity mix in 2050 globally.

Share of electricity generation from renewable sources in 2015 and 2050. Gas capacities in 2050 only use renewable based gas. In 2050, nuclear power still accounts for a negligible 0.3% of the total electricity generation, due to the end of its assumed technical life, but could be phased out earlier.

A 100% renewable global electricity system is also way more efficient. It can reduce global greenhouse gas emissions in the electricity sector from about 11 GtCO2eq in 2015 to ZERO emissions by 2050. The total losses in a fully renewable electricity system are significantly lower than in the current system. And the global transition to a 100% renewable electricity system will create 36 million jobs by 2050, in comparison to 19 million jobs in 2015.

Total LCOE of global power supply in 2015 and 2050.

The global energy transition scenario is carried out in five-year time periods from 2015 until 2050 and provides handy roadmaps to 100% renewable electricity for major regions of the world: Europe, Eurasia, MENA, Sub-Saharan Africa, SAARC, Northeast Asia, Southeast Asia, North America and South America. These are unique roadmaps, also showing the way to fulfilling the Paris Agreement targets, signed by nearly all countries in the world.

The study shows that there is no reason to invest any single dollar in fossil fuel or nuclear power production. It also proves that energy transition is no longer a question of technical feasibility or economic viability, but of political will.

The science has proven that it is feasible.    It is now the turn of politicians, businesses and civil society to push for immediate actions, accelerating the transition.

Gaining public support is the first and most decisive prerequisite for a successful transition to renewable energy. Therefore, policy makers should adopt favourable political frameworks and instruments, promoting fast and steady growth of renewables on the one hand and phasing out all subsidies to fossil fuel and nuclear power generation on the other hand.

The German Renewable Energy Sources Act (EEG) with a fixed feed-in-tariff is one of the best-known and proven successful policies. We also need to implement new, innovative political measures encouraging investment in renewable energy, storage and network integration simultaneously. A reformed version of the EEG  —  a hybrid renewable power plant remuneration  —  enables just that.

On the economic side of the energy transition, sufficient flow of private investment in renewables and storage technologies needs to be ensured for a smooth, fast, and cost-effective transition to 100% renewable energy.

Tendering procedures are most prominent nowadays when it comes to commissioning renewable power projects. Yet science also shows that tendering is reasonable only for renewable energy capacities above 40 MW. Otherwise they limit investors to large companies and exclude investment from decentralized actors, such as cooperatives. Tenders also limit the overall installations, whereas the feed-in-tariffs allow more and faster dynamics in the deployment of renewables.

Last but not least, research and education in the sphere of renewable energy and zero-emission technologies needs to be boosted. This will ensure more effective power generation in the future and new technological breakthroughs in the field of renewables.

The study is part of a larger study analyzing the entire energy system, including electricity, heat, mobility, desalination, and industrial demand. Lappeenranta University of Technology and the Energy Watch Group will publish the findings of the entire study in 2018.

*The study “Global Energy System based on 100% Renewable Energy” is co-funded by the German Federal Environmental Foundation (DBU) and the Stiftung Mercator.

Renewables 🌟 Now Contribute Nearly One-Fifth of U.S. Electricity Generation

By Lorraine Chow

Feb. 16, 2018 11:56AM EST

Renewable energy now makes up 18 percent of total electrical generation in the U.S., roughly double the amount a decade ago, a new report shows.

According to the sixth annual Sustainable Energy in America Factbook, which outlines key U.S. energy trends, renewable energy output in the power sector soared to a record high last year and could eventually rival nuclear.

The factbook, produced for the Business Council for Sustainable Energy by Bloomberg New Energy Finance (BNEF), shows that renewable generation boomed 14 percent in 2017 to hit 717 terawatt hours (TWh). This increase was driven mostly by the West Coast's rebound in hydropower generation after years of drought as well as new wind and solar projects built in 2016 coming online in 2017.

Rachel Luo, senior analyst for U.S. utilities and market reform at BNEF and lead author of the report, told Greentech Media that 18 percent might not sound like a lot but it brings renewable energy "within striking distance" of nuclear, which contributes about 20 of total annual U.S. electricity generation.

"In 2017 it's a very significant story that renewables are making a lot of headway in pushing forward the decarbonization of the power sector, even as the natural gas share decreases," she said.

Indeed, as this chart below shows, natural gas slipped 2 percent last year, from 34 percent in 2016 to 32 percent in 2017. Coal, which used to dominate the U.S. energy landscape, has also shrunk to 30 percent.

2018 Sustainable Energy in America Factbook

Even though natural gas is still the number one producer of U.S. power, "[its] downtick could be from a variety of factors [such as] the increasing penetration of renewables, but load growth is also stalling and … natural gas prices have recovered a little," Luo told Greentech Media.

In summary, the factbook said: "The massive and historic transformation of the U.S. energy sector clicked into a higher gear in 2017, despite new policy uncertainties. Renewable deployment grew at a near-record pace, energy productivity and GDP growth both accelerated, and the U.S. became a serious player in the global liquefied natural gas market. All of this combined to squeeze U.S. greenhouse gas emissions to a 25-year low, while keeping costs in check for consumers."

100+ Cities Now Powered by at Least 70% Renewables  ✨ 🎋 🎍

February 27, 2018

By Lorraine Chow

A growing list of cities and municipalities is leading a renewable energy revolution that their national governments either cannot—or will not—address.

More than 100 cities around the world now get at least 70 percent of their electricity from renewable sources such solar, wind, geothermal and hydropower, according to new research from the non-profit CDP. That's more than double the 40 cities reporting they were powered by at least 70 percent clean energy in 2015.

The list includes large cities with dense populations such as Auckland, New Zealand; Nairobi, Kenya; Oslo, Norway; Seattle, USA; and Vancouver, Canada.

Impressively, a remarkable 43 cities, including Burlington, Vermont; Reykjavik, Iceland; and Basel, Switzerland, are running on 100 percent renewables.

Burlington —Vermont's largest city, with a population of 42,000 people—became the first U.S. city to run entirely on renewable electricity back in 2015. The city gets all of its electricity from wind, solar, biomass and hydropower and even has its own utility and citywide grid.  

"We have seen first-hand that renewable energy boosts our local economy and creates a healthier place to work, live and raise a family," Burlington Mayor Miro Weinberger said. "We encourage other cities around the globe to follow our innovative path as we all work toward a more sustainable energy future."

CDP, formerly the Carbon Disclosure Project, holds energy information on more than 570 of the world's cities. The research was released ahead of the Intergovernmental Panel on Climate Change conference in Edmonton, Canada on March 5, where city governments and scientific leaders will meet on the role of cities in tackling climate change.
In the U.S., roughly 58 cities and towns, including major metropolises like Atlanta and San Diego, are rejecting fossil fuels and have announced plans to run entirely on clean energy.

And with some 275 cities now reporting the use of hydropower, 189 generating electricity from wind and 184 using solar photovoltaics, CDP expects to see more cities around the globe join this important movement.

The CDP said that much of the drive behind city climate action and reporting comes from the 7,000-plus mayors that signed up to the Global Covenant of Mayors for Climate and Energy and have pledged to act on climate change.

"Cities are responsible for 70 percent of energy-related CO2 emissions and there is immense potential for them to lead on building a sustainable economy," said Kyra Appleby, director of cities at CDP.

"Reassuringly, our data shows much commitment and ambition. Cities not only want to shift to renewable energy but, most importantly—they can. We urge all cities to disclose to us, work together to meet the goals of the Paris Agreement and prioritize the development of ambitious renewable energy procurement strategies. The time to act is now."
