Wind turbines can be used as auxiliary and supplemental power sources (ASPSs) for wastewater treatment plants (WWTPs). The use of wind power to generate electricity at WWTPs offers several advantages. Depending upon the size of the wind generation unit, energy production can be inexpensive when compared to conventional power production methods. The cost to generate the electricity decreases as the size of the generating units (e.g., from a wind farm) increases. Wind turbine power is an infinitely sustainable form of energy that does not require any fuel for operation and generates no harmful air or water pollution; it produces no greenhouse gases or toxic or radioactive waste. In addition, the land below each turbine can still be used for other purposes.
