As the small wind industry grows, it’s becoming easier to buy certain models of turbines online and from big-box retailers. For example, Southwest Windpower offers the Skystream 3.7 through Home Depot and now offers the Whisper 100 through Lowe’s. Whisper 100 can produce up to 100 kWh a month in moderate to high winds, according to Southwest Windpower.
Carolyn and Kyle Cave, both university professors in Hadley, Massachusetts, built this super-insulated home to minimize energy consumption. Then they dropped a 20kW solar PV array on the roof and now use energy from the sun to generate a surplus that also powers this tiny little Wheego LiFe electric vehicle. I was able to ask Carolyn Cave a few questions about their solar-powered situation, and this is a portion of that response:
During Greenbuild in Toronto, CertainTeed Corporation introduced a new solar photovoltaic system called the Apollo Solar Roofing System. Apollo skips the rack and mount for a seamless profile that integrates with standard roof shingles. Each 12-pound module has 14 high-efficiency, polycrystalline silicon solar cells that soak up the sun and convert it to energy to power the underlying home.
