= Alternative Energy = Hydroelectric energy Hydroelectric power is power falling from water. == ﻿How It Works == Hydroelectric power works buy first building a dam. The dam then catches water and sends it through a tube which then turns a turbine and the turbine than makes the generator spin and the generator goes to a powerline and makes elecricity. Since all the water goes back into the river after turning the turbine it is more accurate, and it makes it renewable.

Hydropower is the renewable energy source that produces the most electricity in the United States. It produces 6% of total U.S. electricity generation and 35% of generation from renewables in 2009. Hydropower is one of the oldest sources of energy. It was used thousands of years ago...not for electricity but for grinding grain! Our Nation's first industrial use of hydropower to generate electricity occurred in 1880, when 16 brush-arc lamps were powered using a water turbine at the Wolverine Chair Factory in Grand Rapids, Michigan.The first U.S. hydroelectric power plant opened on the Fox River near Appleton, Wisconsin in 1882.
