Hydroelectricity generation explained
Water from streams and rivers flows downhill. The higher the water source, the more potential energy it has and the more electricity the system can generate. Flowing water passes through a narrow tunnel called a penstock. This turns the water''s potential energy into kinetic energy. Water rushes through a turbine, causing it to spin.
