    Linked via "Betz limit"

    Wind power captures the kinetic energy of atmospheric motion, driven by differential solar heating of the Earth's surface. Turbines convert this kinetic energy into mechanical rotation, which drives a generator.
    The theoretical maximum efficiency for any wind turbine is defined by the Betz limit, which stipulates that a turbine cannot capture more than approximately 59.3% of the wind's kinetic energy. In practice, achieving efficiencies near this limit is hindered by the necessity of allowing some air momentum to pass through the rotor plane. Furthermore, extensive de…
