Small Wind

Small Wind Energy Systems (Wind Turbines) contain electric generators that convert the power of the wind into clean, emissions-free power for individual homes, farms, and businesses. In most areas of the country small turbines may be suitable for owners with as little as one acre of land , and some designs may even be suitable for roof-mounting in certain urban environments.

Additional Resources

  • The Department of Energy has prepared maps showing average annual wind speeds in each of the 50 states : http://www.windpoweringamerica.gov/wind_maps.asp . The maps are a convenient way to find out the average annual wind speed at your location. Note, however, that at a micro level the speed, frequency, and variability of the wind can vary significantly. Ultimately, you should have a professional take readings at your site to determine if it is suitable for a wind turbine before you move ahead.
  • The National Renewable Energy Laboratory (NREL) has produced individual Small Wind Electric Systems Consumer's Guides for 38 of the 50 states. NREL's state Consumer's Guides are available for download here: http://www.windpoweringamerica.gov/small_wind.asp . (Don't be deterred if a Consumer's Guide is not available for your state--it does not mean that your state is unsuitable for wind!).
