The document discusses the main parts and functions of wind turbines. It explains that wind turbines use blades, a gearbox, shaft, generator and hub to capture wind energy and convert it into electricity that can power homes and cities. The blades spin from the wind, turning the shaft which then turns the generator to produce energy that is stored in batteries.
