Renewable Energy Fact Sheet: Wind Turbines
www.epa.govWind 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−produces no green house gases and toxic or radioactive waste. In addition, the land below each turbine can still be used for animal grazing or farming. ...

This stream-tube expansion shows that c p ( u) has a physical limit called Betz limit such that c p ( u) ≤ 16/27 ≈ 0.593 [ 2 , 5 ].Regardless of its design, a wind turbine can thus extract at most 59.3% of the wind energy.
