  • `Anti-noise` silences wind turbines

    If wind energy converters are located anywhere near a residential area, they must never become too noisy even in high winds. Most such power units try to go easy on their neighbors' ears, but even the most careful design cannot prevent noise from arising at times: One source is the motion of the rotor blades, another is the cogwheels that produce vibrations in the gearbox. These are relayed to ...

  • Largest wind R&D study underway at NREL

    Strong winds are a common research partner for scientists working at NREL's National Wind Technology Center (NWTC). Recently, those gusting Colorado winds helped usher in a new milestone for wind technology research and development. NREL and Siemens Power Generation 'flipped the switch' starting the blades on a Siemens 2.3 megawatt wind turbine installed as part of a cooperative research and ...

  • With a boost from innovation, small wind is powering ahead

    The Solarium, a new 8-story apartment building in New York City, is part of a new wave of green buildings in Gotham. Its exterior is made from 100 percent recycled material. The burnished floors are sustainably farmed bamboo. The apartments lack bathtubs in order to save water. Perhaps the most novel green accoutrement of the Solarium, however, is a small, black windmill perched on a short pole ...
