Over 2,000 years ago, Chinese and Persian engineers independently developed the first windmills, to pump water for irrigating crops. Windmills first appeared in Europe during medieval times, when they were used for agricultural and industrial purposes.
Modern wind turbines consist of three parts - rotor blades, nacelle, and tower. The blades convert wind energy into mechanical energy. The nacelle houses the inner workings of the wind turbine that are responsible for electrical power generation. The tower supports the structure of the wind turbine and lifts the rotor blades high above the ground into stronger, more continuous winds.
