Hydroelectricity. Amar Hathiramani. Period 5.
Introduction of Hydroelectricity. There are 1,444 hydroelectric plants in the nation. It generated 7% of the nations electricity last year. Washington, Oregon, Vermont, and Idaho use it a lot. These states have 56-69% of hydroelelectricity.
History of Hydroelectricity. Began over 2000 years ago. Spread to Europe in the middle-ages. First example is the water wheel. Hoover dam made between 1931 and 1936.
How Hydroelectricity Works Turbine uses energy from falling water. Kinetic energy turns into mechanical energy. Generator turns mechanical energy into electric energy. Electric energy is distributed to public. Goes through power lines.
What Are the Advantages To Hydroelectricity? It does not pollute the environment. It can prevent flooding. Uses water and nothing bad. It does not have to filter water.
Disadvantages to Hydroelectricity. Public has limited use to reservoirs. It can cause droughts. Limited reservoirs. It is expensive. Marine life can be exposed.
