A wind turbine is a device that converts the kinetic energy of wind into electrical energy. As of 2020, hundreds of thousands of large turbines, in installations known as wind farms, were generating over 650 gigawatts of power, with 60 GW added each year. Wind flows over the blades creating lift (similar to the effect on airplane wings), which causes the blades to turn. This chapter comprehensively discusses wind power generation, tracing its evolution from historical windmills to modern large-scale wind farms, and analyzing its technical principles, resource distribution, and global development. It details the operational mechanisms of horizontal-axis (HAWTs) and. Wind power is the use of wind energy to generate useful work. Today, wind power is generated almost.
