Wind energy offers an environmental friendly fuel alternative to fossil fuel-generated electricity. Windmills are required to convert this “green” energy of the wind into electricity. Because of the remote location of many windmills, sensors serve as critical components in their operation, maintenance and safety.
Virginia Tech recently was named the overall winner of EcoCAR: The NeXt Challenge, a three-year collegiate vehicle engineering competition sponsored by the U.S. Department of Energy and General Motors (GM).
Rapidly falling prices in 1H’11 have been unable to stimulate the faltering European PV market, according to the latest Solarbuzz European PV Markets Report. Signs of a strengthening market in June 2011 were hit by cancellation of the anticipated mid-year incentive tariff reductions in Germany.
This week, Allison shared her experience of adding insulation to her attic. The result? A better-insulated home with less use of her air conditioning system. It's one of several things she's doing to keep her home cool during the summer (though insulation is effective year round)....
The Better Use of Light Bulbs Act (BULB) has been defeated in the House of Representatives. BULB would have amended the 2007 Energy Independence and Security Act, thereby staying the incandescent ban. But it was not to be. With no further challenges, the Edison Lightbulb faces mandatory retirement in January 2012.
