Government Study Shows U.S. Wind Resources Larger than Previously Estimated | Alison Pr... - 1 views

  •  
    "A new study by the Department of Energy's National Renewable Energy Laboratory (NREL) has revealed that U.S. wind resources are far greater than previously believed. The study, a collaborative project between NREL and AWS Truewind, LLC, of Albany, New York, created resource maps and wind potential tables for 48 states. The recent study is the first comprehensive update of the wind energy potential by state since 1993. The resource maps for the contiguous United States, and separately for each state, show the predicted mean annual wind speeds at 80-meter height. They are derived from 200-meter resolution maps developed by AWS Truewind for the windNavigator system. Areas with annual average wind speeds around 6.5 m/s and greater at 80-meter height are generally considered to have suitable wind resources for wind development"

Nanotechnology Now: "Nanoparticle breakthrough could improve solar cells" - 1 views

  •  
    Abstract: The sun may soon power many more homes and appliances, thanks to chemists at Idaho National Laboratory and Idaho State University. They have invented a way to manufacture highly precise, uniform nanoparticles to order. The technology, which won an R&D 100 Award this year, has the potential to vastly improve photovoltaic cells and further spur the growing nanotech revolution. Nanoparticle breakthrough could improve solar cells Idaho Falls, ID | Posted on October 29th, 2009 INL chemist Bob Fox and his ISU colleagues were looking for a better way to make semiconducting nanoparticles for solar cells. When the researchers introduced "supercritical" carbon dioxide - CO2 that behaves like both a gas and a liquid - to their reactions, they generated high-quality nanoparticles at low, energy-saving temperatures. And, surprisingly, the nanoparticles were incredibly uniform. With subsequent tweaking, the team figured out how to make nanoparticles of prescribed sizes - anywhere from 1 to 100 nanometers - with unprecedented precision. Because the properties of nanoparticles are so strongly size-dependent, the implications of this breakthrough are vast.

Arizona Rep. Giffords authors U.S. Solar Roadmap bill as CA plows ahead - 0 views

  •  
    In continued efforts to promote clean energy, U.S. House Representative Gabrielle Giffords (D-AZ) has introduced the Solar Technology Roadmap Act, which is now on its way to the full House after achieving commendable bipartisan support after short deliberation in the Science and Technology Committee. Giffords' bill would designate the U.S. Department of Energy (DOE) as the leading organization for developing a strategic plan to direct solar energy research and its deployment into the commercial sector. The legislation would also allocate $2.25 billion for solar research over the next five years, which is a far cry from the pro-oil Bush administration that pillaged funding for renewables.

Key New Ingredient In Climate Model - Environment - an eLab Article at Scientist Live - 0 views

  •  
    For the first time, climate scientists from across the country have successfully incorporated the nitrogen cycle into global simulations for climate change, questioning previous assumptions regarding carbon feedback and potentially helping to refine model forecasts about global warming. The results of the experiment at the Department of Energy's Oak Ridge National Laboratory and at the National Center for Atmospheric Research are published in the current issue of Biogeosciences. They illustrate the complexity of climate modeling by demonstrating how natural processes still have a strong effect on the carbon cycle and climate simulations. In this case, scientists found that the rate of climate change over the next century could be higher than previously anticipated when the requirement of plant nutrients are included in the climate model. ORNL's Peter Thornton, lead author of the paper, describes the inclusion of these processes as a necessary step to improve the accuracy of climate change assessments.

Swarm power for Germany - UPI.com - 1 views

  •  
    How about a power station in your basement? In a bid to create a decentralized electricity grid, German carmaker Volkswagen is launching thousands of mini power plants that could be installed in the basements of any residential home. Together with clean energy provider Lichtblick, Volkswagen plans to install up to 100,000 small power plants -- able to generate heat and electricity -- in people's homes to generate enough energy to offset two nuclear power plants. Taken together, all mini plants would have a capacity of 2 GW. The project could lure many Germans away from traditional utilities toward decentralized energy generation, which experts say will be the buzzword of tomorrow's energy mix.

  •  
    Germany's first offshore wind farm has gone online off the North Sea island of Borkum. A year late and 50 million euros over budget, it's still the best hope proponents of green energy have for meeting the country's ambitious emissions reductions targets. Electricity generated by Germany's first offshore wind energy park began streaming into the national network on Wednesday as three wind turbines located 45 kilometers (28 miles) north of the North Sea island of Borkum went online. The three wind turbines are massive. Each towers more than 100 meters (328 feet) above the waves, with blades spanning more than 116 meters. Individually, the wind turbines are capable of generating 5 megawatts of energy per year. The initial trio will be joined later this year by nine more wind turbines. When all 12 go online later this year, the installation is expected to provide enough electricity to power 50,000 homes.
