U.S. Wind Resource Map
The national 80-meter wind resource map can give you a macro view of wind resources in the United States. Click on a state of interest to view the state's 80-m map to determine if your area of interest should be further explored. Wind resource at a micro level can vary significantly; therefore, you should get a professional evaluation of your specific area of interest. You can zoom or print the full U.S. map.
This map shows the predicted mean annual wind speeds at 80-m height (at a spatial resolution of about 2 km that is interpolated to a finer scale). Areas with annual average wind speeds around 6.5 m/s and greater at 80-m height are generally considered to have suitable wind resource for wind development. NREL has conducted a preliminary review and validation of the AWS Truepower's 80-m map estimates for 19 selected states (6 Western states, 6 Midwestern states, and 7 Eastern states) based on tower measurements at heights of about 50 m and above from more than 300 locations.
These maps resulted from a collaborative project between the National Renewable Energy Laboratory and AWS Truepower of Albany, New York. NREL has worked with AWS Truepower for almost a decade on updating wind resource maps for 36 states and producing validated maps for 50-meter height above ground. U.S. Department of Energy's WINDExchange initiative supported the mapping efforts.
