China to Double Solar Power Capacity by End of 2011 (+ Top Solar Power Stories) Clean Power Published on August 16th, 2011 | by Zachary Shahan Nicholas just wrote about China’s solar power dreams and it’s new feed-in tariff for solar yesterday.
And I wrote in June about the country doubling its 2025 solar power goals (aiming for 10 gigawatts by that time). But we’ve got some more big solar news out of clean-energy-crazy China worth a share. China expects to double its solar power capacity by the end of the year and will reach 2 gigawatts of solar power capacity, according to a new report from a think tank linked to the government, the Energy Research Institute. “The report also said China was expected to produce 90,000 tonnes of polysilicon this year, representing 80 percent of its domestic demand,” Reuters reports. Single, key gene discovery could streamline production of biofuels. A team of researchers at the Department of Energy's BioEnergy Science Center (BESC) have pinpointed the exact, single gene that controls ethanol production capacity in a microorganism.
This discovery could be the missing link in developing biomass crops that produce higher concentrations of ethanol at lower costs. "The Department of Energy relies on the scientific discoveries of its labs and research centers to improve the production of clean energy sources," said Energy Secretary Steven Chu. Wind Cube: A Clever Design for a Personal Wind Farm Right on Your Own Home. Chen Liao Hsun has been envisioning a future of renewable energy that individuals can use right at home.
His concept, the Wind Cube, would allow each homeowner to install personal wind turbine generators right on the sides of their houses. The Modularized Wind Power Systems could help offset each family’s reliance on grid power, and lower monthly bills. Wind Cubes can be installed alone or in groups, easily connecting with other units to create a honeycomb tile pattern. They mount sturdily to unseen exterior walls, or on rooftops, and hook right into a home’s energy network. Each unit can generate 100 watts of power, thanks to retractable blades. In actuality, Hsun estimates that each cube unit can generate 21.6 kilowatt hours of electricity per month, which equals around 1/15th of the power needed for a household of four.
Via Design Boom. Energy: Strategies, Policy & Best Practices for the Northwest. Washington Legislature report on high performance buildings You may recall when the 2005 Washington State Legislature established high performance requirements for public buildings.
The bill required that state agencies, some schools, and certain others follow high-performance building standards. High-performance buildings, also known as “green buildings,” are designed and constructed to standards intended to promote environmental conservation, such as Energy Star or LEED. What might not have stuck in memory for five years is that the bill also required state entities and school districts to document and report the added costs and operational savings of their projects.
That’s not happening, according to a Joint Legislative Audit and Review Committee of the Legislature. It may be too early to judge, but it’s not too early to report the results that are available. If you don’t have time for 46 pages of reading, consider taking in the two-page summary at the beginning of the JLARC report. Germans Encouraged to Roof Carports with Solar Panels. Clean Power Published on August 13th, 2011 | by Charis Michelsen Carports and garages are both perfectly serviceable structures to protect your car.
We’re talking about carports here, though, so we’re just going to mention that they’re cheap, easy to build, and have great air circulation. There’s one more advantage to a German carport – it’s incredibly simple to roof it over with solar panels and let solar energy pay for the carport. Give it twenty years, and it’s paid for itself four or five times over. Although incentives will decrease significantly for anything built after 2012, as of August 2011, solar power units on a roof generate an incentive of 28.74 cents (Euro, of course, which is about $0.41 American) per kilowatt hour, up to 30 KW. Bringing Birds Back to Regrowing Forests: Scientific American Podcast. The Amazon rainforest near Manaus in Brazil was almost completely cleared decades ago for cattle grazing.
Fragments of the original forest remained, thanks to government policies that required some trees to be left standing. But these sections were too small to support various bird species. A 25-year study of 11 of the fragments now finds that the birds can come back—if the pieces are reconnected. The research was published in Public Library of Science ONE. During the first year after land clearing, bird species such as the black-banded woodcreeper and the black-throated antshrike disappeared locally. But by 2007, cattle grazing in the area had been abandoned and the forest began to come back. In other words, as lead author and L.S.U. ornithologist Phillip Stouffer says quote "developing second growth forest around fragments encourages recolonization.
