Wind
Wind turbine systems are best used in areas where the annual average wind speed (at 100 feet in the air) is 10 mph or greater, though new turbines are being developed that will produce electricity in winds lower than that.
After average wind speed is determined average household energy requirements are determined and that determines the size of the wind turbine needed.
The technology has improved greatly over the years and the wind turbines are quiet and can generate power in winds as low as 8 mph.
