The highest windpower areas are found along the Atlantic Ocean and Delaware Bay coastal areas, and on the ridges of western and northwestern New Jersey. These ridge tops may be subject to high wind shear and particular areas could have higher wind power class values at 80 m than shown on the 50-m chart.

A renewable resource, wind is categorized according to wind power classes, which are made from usual air velocity. These classes vary from Class 1 (the lowest) to Class 7 (the peak). Generally, at 50 meters , windpower Class 4 or greater is effective for generating wind energy with sizeable turbines. Class 4 and above are deemed good resources. Individual locations in the Class 3 zones might have higher wind power class values at 80 meters than shown on the 50 meter map as a consequence of potential high wind shear. As a result of the advances in machinery, many locations in the Class 3 zones may suitable for large scale wind power company development.
