This is a utility-scale, land-based map of the mean annual wind speed 80 meters above the ground. This map can be used to evaluate the potential for wind energy in the US. State maps and more information are linked from the main map.

Video introduces wind energy research at the National Renewable Energy Lab (NREL) and provides an overview of the NREL Wind Technology Center near Boulder, Colorado.

This animated map shows prevailing surface wind direction and strength across the lower 48 states of the US.
