About hydroelectricity

A hydroelectric generating station is a plant that uses water as the driving force to produce energy. Water enters the generating station and travels through a pipe that quickly drives it to the turbine. The turbine’s role is to use the water’s energy to turn the generator, which converts the mechanical energy to electrical energy. The water is sent back to the river by way of a tailrace.
