September 29 Green Energy News

Science and Technology:

  • A new Copper-Indium-Gallium-Selenide thin-film solar cell conversion efficiency record was recently achieved by researchers at the Center for Solar Energy and Hydrogen Research in Stuttgart. The new conversion efficiency record of 21.7% beats the previous record of 21%. [CleanTechnica]
  • Chinese solar manufacturer JA Solar Holdings says it has attained 20% solar energy conversion efficiency in its multi-crystalline silicon solar cell, which it says is a world record for a multi-Si solar cell efficiency. This is just 9 months after it had set a previous record of 19% efficiency in its multi-Sci cells. [CleanTechnica]


  • Brazilian auctions to be held in November received bidding applications from 1115 projects totalling 53.87 GW. Wind power has the greatest capacity share. Wind’s chief competition is from 39 combined cycle gas projects totalling 20.61 GW and 224 solar photovoltaic projects totalling 6.1 GW. [Windpower Monthly]
  • Cutting the renewable energy target will leave Australians reliant on natural gas and drive up electricity bills, a group of consumer and community advocates say. They have written to prime minister Tony Abbott urging him to reject recommendations of a review that called on the government to cut the target.

  • Britain’s first ever floating solar panel project has just been built in Berkshire. The 800-panel green energy project was installed earlier this month on a reservoir at Sheeplands Farm, a 300-acre soft fruit farm near Wargrave. The project will supply 200 kW. The developer says larger systems could be easily built. []
  • Saskatchewan’s government-owned power utility is set to launch a carbon-capture-and-storage project this week. SaskPower says it is the world’s first and largest commercial-scale, carbon-capture operation of its kind. It will capture carbon dioxide emissions from burning coal to store them deep underground.

  • Solar Frontier, the solar arm of Japanese oil refiner Showa Shell Sekiyu, has revealed bold plans to build a solar manufacturing facility in Buffalo, upstate New York. The company was attracted by low solar costs that make PV in the US an attractive energy option for many. [pv magazine]
  • A 1.8 MW solar project has been installed in New Bedford, Massachusetts. In all, 16.25 MW of projects are now installed or under construction. When all 16 MW of projects are completed New Bedford will have exceeded the city’s 2011 goal of purchasing 10 MW of power from renewable sources within five years. []
  • Panda Power Funds and Texas officials gathered to dedicate the company’s 758 MW natural gas-fueled, combined-cycle power plant in Temple, Texas. The plant is one of the most advanced gas-fueled power stations in the nation, establishing new standards within its class. [Today’s Energy Solutions]
  • Carbon emissions in the US are higher than expected for 2014. Carbon dioxide emissions due to the consumption of coal were more than 12% higher during the first half of 2014 than during the first six months of 2012, while those from natural gas and petroleum rose by 7.3% and 0.8% respectively. [Business Green]
  • Unsatisfied with the pace at which the federal government is acting to reduce greenhouse gas emissions, several US states are forging ahead with their own initiatives. The first year of the California program was a resounding success, with the state’s economy expanding while at the same time adding renewable energy. []
  • In Oregon, the Department of Transportation is building solar stations along the roads. It has already built two solar stations and is looking into a third, built without state money and on property already owned by the state and cleared for development as highway right-of-way.
