If your State does not have a wind resource map, the national 80-meter map below can give you a macro view of wind resources in the United States. From this map, you can 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 (PDF 4.2 MB) Download Adobe Reader.
This map shows the predicted mean annual wind speeds at 80-m height (at a spatial resolution of 2.5 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 Truewind'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 Truewind of Albany, New York. NREL has worked with AWS Truewind 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 Wind Powering America project supported the mapping efforts.
