Large solar projects can be done responsibly

BY SHANNON EDDY, Special to The Bee:  As the seventh-largest economy in the world and a clean-energy leader, California plays a key role in shaping the global response to climate change. The benefits of our leadership will be on the world stage later this month during the international climate talks in Paris. Over several decades, California has successfully advanced the development of renewable energy resources. As a result, the state boasts the highest concentration of solar projects in the nation, including several of the world’s largest. Large-scale solar power plants are enabling California to meet the goals of reducing carbon emissions to 1990 levels by 2020 and generating 50 percent of its electricity from renewable sources by 2030. Eleakis & Elder Photography As with any fast-growing, successful industry, it’s essential to ask questions about unintended consequences. We agree it is important to evaluate how the environmental benefits of large-scale solar – carbon reduction, reduced water use and improved local air quality – compare to any negative consequences for people and the environment.   Cont'd...

Solar Power Thrives In Chile, No Subsidies Needed

William Pentland, Contributor for Forbes:  In Chile’s most recent power auction, the bids from solar project developers came in at between $65 and $68 per megawatt hour (MWh) were considerably more competitive than bids made by coal plants, which were priced at $85 per MWh. Solar power projects were awarded the lion’s share of the 1,200 gigawatt hours (GWh) of electricity contracts sold. Chile boasts one of the world’s biggest solar resources. High electricity prices and strong demand from Chile’s mining industry have driven demand growth for solar, especially large scale commercial or utility projects. The total installed solar capacity in Chile increased from less than 4 MW in 2013 to more than 220 MW last year. Nearly 1 GW of solar is projected to be installed in Chile in 2015. Meanwhile, a total of about 8 GW of solar power projects have been approved for development in Chile. First Solar and SunEdison are two of the biggest U.S. solar companies active in Chile.   Cont'd...

Say Goodbye to Solar Power Subsidies

Mark Chediak & Chris Martin for Bloomberg Businessweek:  In 2016 the U.S. will learn if renewable energy can survive without government support. The most significant tax credit for solar power will expire at the end of 2016, and the biggest one for wind already has. These federal subsidies have provided wind and solar developers with as much as $24 billion from 2008 to 2014, according to Bloomberg New Energy Finance. That’s led to a 12-fold increase in installed capacity over the past decade, helping lower costs at least 10 percent each year. Combined, wind and solar still generate less than 5 percent of electricity in the U.S. The subsidy cuts come as both industries face stiffer competition from ultracheap coal and natural gas. An NYSE Bloomberg global index of solar stocks, including those of big developers SunEdison and First Solar, has fallen about 35 percent since June. A comparable wind index is down 20 percent.   Cont'd...

UK building the world's largest offshore wind farm

By Kelly Hodgkins for Digital Trends:  Danish state-owned company Dong Energy A/S plans to set a new world record for the world’s largest offshore wind farm, breaking the existing record currently held by the 630-megawatt London Array, another facility built by Dong. The new U.K. wind farm will be located in the Irish Sea, about 12 miles off the west coast of Great Britain.​ When commissioned, it will provide enough energy to power almost a half million homes. It’s no surprise that Dong is behind this effort, as it is Denmark’s largest energy company and the world’s largest developer of offshore wind power. The company has a longstanding relationship with the UK, constructing and, in some cases, operating multiple offshore wind facilities, including those in Barrow, Burbo Bank, and Walney Island. Between these projects and others in Germany, Dong now has a total of 5.1 gigawatts of offshore wind capacity. It aims to expand this capacity even further with a projected goal of 6.5 gigawatts of offshore wind energy production by 2020.   Cont'd...

Thin film perovskite solar cell passes the efficiency test

Matthew Gunther for Chemistry World:  Perovskite solar cells may one day rival silicon-based technologies, but their performance outside the laboratory has been a constant source of contention in the past year. Now, an international team of scientists has manufactured the first thin film perovskite solar cell with a reported efficiency that has beenofficially recognised by an accredited national test laboratory.1 Since their development in 2012, the performance of light-harvesting metal–organo halide structures has seemingly improved at a staggering rate, with their efficiency increasing by six percentage points in just two years – the same increase took multi-crystalline solar cells over two decades. But their stability has been brought into question, with some international test centres taking issue with perovskite solar cells that are so unstable that they may degrade spontaneously in air, making it hard for them to assess their performance. It’s a state of affairs that Michael Grätzel from the Ecole Polytechnique Fédérale de Lausanne in Switzerland has had trouble dealing with. ‘Conspicuously, you could see that from the very beginning there was very scarce information on the stability of these devices,’ comments Grätzel. ‘I have raised that issue many times – one would think that now everybody does stability work after this alarm was sounded, but not so.'   Cont'd...

Morocco to Build World's Largest Concentrated Solar Power Plant

Cole Mellino for EcoWatch:  Morocco imports 97 percent of its energy, and yet it has one of the highest rates of solarinsolation of any country—about 3,000 hours of sunshine per year, according to the Solar GCC Alliance. To put that in perspective, the Guinness Book of World Records puts Yuma, Arizona as the sunniest place on Earth with an average of 4,055 hours of sunshine per year (the theoretical maximum is 4,456), whereas the sunniest place in Germany, which still has a robust solar industry, gets a mere 1,800 sunshine hours a year. So it’s no surprise that Morocco is tapping into its abundant sunshine for energy. Morocco is building “a complex of four linked solar mega-plants that, alongside hydro andwind, will help provide nearly half of Morocco’s electricity from renewables by 2020,” reports The Guardian. When the entire project is finished, it will be the world’s largest concentrated solar power plant in the world. The first phase, Noor 1, will go live next month.   Cont'd...

United Utilities installs Europe's largest floating solar power project on reservoir

By Emily Gosden, Energy Editor for Telegraph UK:  Water giant United Utilities is to install Europe’s biggest floating solar power system on a reservoir near Manchester, as it seeks to capitalise on the novel technology to cut its energy costs. The 12,000 panel, £3.5m development will be only the second of its kind in Britain, dwarfing an 800-panel pilot in Berkshire last year, and will be the second biggest in the world after a scheme in Japan. Installation of the panels is due to begin on Monday at the Godley reservoir in Greater Manchester, where it will provide a third of the power for a water treatment works. The system is scheduled to be completed before Christmas, in order to qualify for subsidies before they are due to be drastically cut in the new year.   Cont'd...
