Hydroelectricity

Hydroelectricity is electricity made by generators that are pushed by the movement of water. It is usually made with dams that block a river to make a reservoir or collect water that is pumped there. When the water is released, the pressure behind the dam forces the water downpipes that lead to a turbine.This causes the turbine to turn, which turns a generator which makes electricity.

Power Production

The use of hydropower involves using the kinetic motion in water as it flows downstream, part of the normal water cycle of the Earth, to generate other forms of energy, most notably electricity. Dams use this property as a means of generating electricity. This form of hydropower is called hydroelectricity.
