United States Wind Map
e-Marine, Incorporated
| This map shows the wind resource in the United States. Land is categorized by wind power class (left column of key), defined by a range of annual average wind speeds measured at 10 meters (33 feet) and 50 meters (164 feet). The columns called Wind Power estimate how much potential energy from the wind (in watts) is available per square meter of land, assuming wind turbine hub height of 10 or 50 meters. (Of course, to calculate Wind Power, assumptions about turbine size and performance were made.) Wind turbines are economical in wind power class 4–7. |
