Hydropower

The ability to turn water into electricity has a long history. Worldwide use of hydro power is at 20 percent and 10 percent in the United States.

Hydropower works by harnessing water in different ways and converting it into electricity. In the United States, the most famous Hydropower plant is the Hoover Dam.

Flowing water is converted to energy by turbines and generators. Water energy today is one of the most used sources of power. This is changing quickly and will drop in the United States from 10 percent to six percent. No new hydro plants are expected to be built in the U.S. for the foreseeable future.
