The Hydro-Québec generating fleet

A hydroelectric generating station is a plant that produces electric power by using water to propel the turbines, which, in turn, drive the alternators.

These power stations generate about a quarter of all the electricity used in the world. With 54 hydropower stations and access to vast water reserves, Hydro-Québec uses water to generate almost all of its energy output–97% in 2002. In this way, the company helps reduce greenhouse gas emissions.

Water rushes down the penstock to the turbine. Its force drives the turbine, which in turn makes the rotor spin and generates the back-and-forth motion of electrons.
