This diagram shows the highest wind supply in Kentucky are found on the ridge crests in the southeastern corner of the map. Class 3 areas are concentrated in the Black Mountain region near the Virginia perimeter.

A renewable resource, airstream is classified by wind power classes, which are created from normal air speeds. The classes span from Class 1 (the lowest) to Class 7 (the maximum). Ordinarily, at 50 meters , windpower Class 4 or greater is functional for producing wind power with large turbines. Class 4 and higher are considered good energy supplies. Specific areas in the Class 3 areas might have superior wind power class values at 80 meters than revealed on the 50 meter map as a result of potential elevated wind shear. Because of the advances in equipment, some locations in the Class 3 areas may appropriate for utility-scale wind power company development.
