This chart indicates that West Virginia has wind resources suitable with utility-scale wind power generation. The good and excellent wind resource areas are concentrated on ridge crests in the eastern portion of the map just south of a Martinsburg-Clarksburg line. There are scattered areas along these ridge crests that are estimated to have outstanding-to-superb windpower.

A source of clean energy, airstream is classified according to wind power classes, which are made from average wind velocity. The classes span from Class 1 (the lowest) to Class 7 (the highest). Ordinarily, at 150 feet , wind power Class 4 or higher can be effective for generating wind energy with big turbines. Class 4 and above are considered good resources. Specific areas in the Class 3 areas may perhaps have greater wind power classes at 80 meters than revealed on the 50 meter map as a result of possible high wind shear. Given the advances in machinery, some locations in the Class 3 zones may appropriate for utility-scale wind power company development.
