Definition

Hydroelectricity- is the production of electrical power through the use of the gravitational force of falling or flowing water.Slide3

explanation

Water is needed to run a hydro electrical power generating unit. The water is held behind a dam, forming an artificial lake, or reservoir. The force of the water being released from the reservoir through the dam, spins the blades of a giant turbine. The spinning turbine is what is used to gather the electricity. Slide4

The largest hydro electric power plants

The largest hydro electric power plants in the world are. The “three gorges dam” in china, the “itaipu dam” in brazil, and the “xiluodu dam” in china. These three dams produce about 196.7 terawatts a year, that’s enough to power all the house hold electronics in the united states.

Major company's

One major company that’s uses hydro electrical power plants is TVA. They have 29 hydro electrical dams, and 1 pumped-storage power plant, together these plants produce about 13.9million megawatts of electricity, enough electricity to power nearly 1million homes for a year Slide6

How much hydroelectricity is the world using

The world uses about 20 percent of hydroelectric power. This powers I billion people in 30 countries. The united states uses about 9% of hydroelectric power. That’s because there is about 8000 dams in the country.Slide7
