http://windspireenergy.com/applications/residential/"Homes across the country are using wind power generated by Windspire wind turbines to generate clean renewable energy and offset their energy use. Only 30 feet tall and silent, the Windspires are designed to fit in well in urban and suburban areas. U.S. homeowners are eligible for a 30% federal tax credit off the total cost of the turbines including installation and available local rebates as much as $4,800 in some states."
