In this chapter, we discuss the different types of wind turbines and the basic technical aspects of large wind turbines for electricity generation. We analyse the performance of wind turbines and discuss their adaptation to a wind regime. The corresponding rated wind speed is about 10.5 m/s, thus about 25% above the yearly mean wind speed

Wind Energy Formula

This formula shows that the power produced by a wind turbine is dependent not only on wind speed but also on the density of the air and the size of the turbine blades. The development of this formula is attributed to the work of physicist Albert Betz in 1919, who introduced Betz''s Law which limits the maximum achievable extraction of wind power by a
