Hydroelectric Power

Hydroelectric power plants have been an inexpensive source of electricity over two centuries.

 

Dams utilize natural flowing waterways to turn massive turbines in order to generate electricity. By harnessing natural water flow, hydroelectric plants are an environmentally friendly alternative to traditional power plants. 

 

In 1900, hydroelectricity accounted for nearly 57 percent of the electricity generated within the United States. Today, hydroelectric power plants supply less than 7 percent of America’s electricity.
