A small wind turbine with an output of 5 kilowatts would power the average home, though turbines generating between 2 and 10 kilowatts can power some homes, as of 2015. People choose turbine size based on a home's energy use, average wind speeds and the turbine's height.
Home wind turbines should be installed at least 30 feet above any obstructions, and the average height of a small wind turbine is about 80 feet. While specific requirements vary from location to location, wind turbines should be placed in an area with average wind speed of at least 12 miles per hour. Zoning regulations may limit who can install a wind turbine, and people rarely use them in urban settings due to zoning restrictions and wind obstructions.
