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.

The 900-watt generator has carbon fiber blades and a rotor diameter of seven feet. The turbine weighs 47 pounds, cuts in at 7.5 mph, and produces 100 kWh/per month in 12 mph winds.  Whisper 100, like other models in the Whisper line, is suitable for powering things like batteries, remote homes, and water pumps.

The price of Whisper 100 varies by location and installation cost; however, I found it listed on for about $2,600.  Plus, purchasers may be able to take advantage of local, state, and federal incentives, including the 30% federal tax credit.
