Want to power your house with a wind turbine? If you want to produce enough power for much of your home, think about a tower, not a small rooftop vertical turbine. According to a representative of Southwest Windpower, which sells residential wind turbines via some Home Depot stores  in Texas, California, Utah, Nevada, Wyoming and Idaho, a rule of thumb for proper and efficient operation of a Skystream suggests that the generator should be 20 feet (6 meters) above the top of anything within 250 feet (about 76 meters).

Skystream 3.7 is designed to work in very low winds, with controls and inverter built in, and produce up to 400 kWh of clean electricity per month depending on the wind resource and site location. Additionally, Skystream 3.7 ranges in price between $15,000 and $20,000 depending on the location of the installation, with a 30 percent federal tax credit available for qualified consumers.
