The U.S. Department of Energy’s Wind Powering America program and the National Renewable Energy Laboratory both publish wind maps of the United States. These maps show estimates of wind speeds at a certain height off of the ground and can help determine if if a windpower system would be viable at your location.
When considering whether windpower is an optimal home renewable energy system for you, look at wind maps in the 30-meter (100 ft.) to 50-meter (160 ft.) height range. In general, an annual average wind speed greater than 12 miles per hour is required for efficient small wind energy systems. Tower height is also a major consideration. Towers must be high enough to catch smooth wind above turbulence caused by ground structures such as trees, buildings or hills.
