A new wind turbine blade design that researchers at Sandia National Laboratories developed in partnership with Knight and Carver of San Diego promises to be more efficient than current designs. It should significantly reduce the cost-of-energy (COE) of wind turbines at low-wind-speed sites.
When someone mentions a mobile home or "house trailer," the image usually doesn't make others green with envy. Mobile homes haven't earned recognition for long-term quality, environmental friendliness or return on value.
A Duke University-led analysis of available records shows that while the North Atlantic Ocean’s surface waters warmed in the 50 years between 1950 and 2000, the change was not uniform. In fact, the subpolar regions cooled at the same time that subtropical and tropical waters warmed.
Biofuels reduce greenhouse-gas emissions in comparison to fossil fuels. In the Jan. 4 issue of the journal Science, Smithsonian researchers highlight a new study that factors in environmental costs of biofuel production.
A Stanford scientist has spelled out for the first time the direct links between increased levels of carbon dioxide in the atmosphere and increases in human mortality, using a state-of-the-art computer model of the atmosphere that incorporates scores of physical and chemical environmental processes.
The amount of wind energy connected to the electricity grid on the island of Ireland is set to breach the 1,000MW threshold by the end of this year.
Xethanol Corporation, a renewable energy and clean technology company, today announced an extension of its Cooperative Research and Development Agreement (CRADA) on cellulosic ethanol feedstocks, with the National Renewable Energy Laboratory (NREL) in Golden, Colorado. The agreement has been extended through March 7, 2008. The NREL lab is operated by the Midwest Research Institute under contract to the US Department of Energy.
In a survey of the northern Basin and Range province of the western United States, geochemists Mack Kennedy of the Department of Energy's Lawrence Berkeley National Laboratory and Matthijs van Soest of Arizona State University have discovered a new tool for identifying potential geothermal energy resources.
The Coastal Habitat Alliance, Inc. today released the results of a scientific review of two proposed wind energy generation projects for Kenedy County, Texas.
EarthFirst Canada Inc. is pleased to announce that it has signed a turbine supply agreement and a long-term service and warranty agreement with ENERCON GmbH for 15 of their E82-2.0 MW wind turbines. These wind turbines are to be delivered for installation in 2009 at EarthFirst’s Grand Valley project in Ontario, Canada.
