Betz limit - Energy Education

The Betz limit is the theoretical maximum efficiency for a wind turbine, conjectured by German physicist Albert Betz in 1919. Betz concluded that this value is 59.3%, meaning that at most only 59.3% of the kinetic energy from wind can be used to spin the turbine and generate electricity.In reality, turbines cannot reach the Betz limit, and common efficiencies are in the 35-45% range.
