The amount of energy one wind turbine generates depends on the size of the turbine and the speed of the wind through the rotor. Wind turbines have power ratings that range from 250 watts to 5 megawatts (MW). The average U.S. household consumes approximately 10,000 kilowatts of electricity per year. One 10 kW wind turbine can generate approximately 10,000 kW per year or enough to power a typical household. A larger wind turbine will generate electricity for more homes.
