Windpower in Arizona

A source of clean energy, wind is organized by wind power classes, these are made from average air velocity. These classes range from Class 1 (the lowest) to Class 7 (the peak). On the whole, at 50 meters , wind speed Class 4 or greater can be practical for making wind energy with large turbines. Class 4 and above are considered high-quality resources. Particular locations in the Class 3 regions may perhaps have higher wind power classes at 80 meters than revealed on the 50 meter map because of potential high wind shear. Because of the advances in equipment, some zones in the Class 3 zones may correct for utility-scale wind power development.
