Community Wind Handbook

Understand Your Energy Use & Costs

Understanding your energy usage and the associated costs is essential in determining the turbine size needed for your small community wind project. For example, a typical U.S. home uses approximately 10,812 kilowatt-hours (kWh) of electricity per year (about 901 kWh per month).[1]

Depending on the average wind speed in an area, a wind turbine rated in the range of 5 to 15 kilowatts (kW) would be required to make a significant contribution to this demand. A 1.5-kW wind turbine will meet the needs of a facility requiring 300 kWh per month in a location with a 14 MPH (6.26 meters per second) annual average wind speed.[2]

To better understand energy usage and to learn more about steps you can take to conserve energy in your home, see the Department of Energy’s EnergySavers: Tips on Saving Money and Energy at Home. Many of these suggestions would also be applicable to a business or other facility.
