• On September 30, 1882, the first hydroelectric power plant began operations along the Fox River in Appleton, Wisconsin. A hydroelectric power plant uses moving water to generate electricity. Paper manufacturer H.F. Rogers was able to generate enough electricity to run the plant, a nearby building, and his own house.

    Today, there are dozens of hydroelectric power plants throughout the world, almost all of them controversial. Hydroelectricity is considered a renewable resource, because water is continually replenished in the water cycle. However, the dams on which many of these facilities depend can devastate the local environment.

    The world’s largest hydroelectric power plant is the Three Gorges Dam on the Yangtze River in Hubei Province, China. In order to build the dam, more than one million people had to move and 140 towns were flooded.
