Delaware has wind supply consistent with utility-scale wind power generation. The good and excellent wind supply is located along the coasts of Delaware Bay and the Atlantic Ocean, especially from Cape Henlopen to the Maryland border.

A renewable energy source, airstream is categorized according to wind power classes, these are based on typical air speeds. These classes range from Class 1 (the lowest) to Class 7 (the maximum). On the whole, at 50 meters , windpower Class 4 or greater can be functional for creating wind energy with larger turbines. Class 4 and above are considered high-quality energy supplies. Particular locations in the Class 3 zones can have higher wind power class values at 80 meters than revealed on the 50 meter map due to potential high wind shear. Due to the advances in technologies, some areas in the Class 3 zones may correct for utility-scale wind power company development.
