Hydropower is electricity generated using the energy of moving water. Rain or melted snow, usually originating in hills and mountains, create streams and rivers that eventually run to the ocean.The energy of that moving water can be substantial, as anyone who has been whitewater rafting knows.ydroelectric power provides almost one-fifth of the world's electricity. China, Canada, Brazil, the United States, and Russia were the five largest producers of hydropower in 2004. One of the world's largest hydro plants is at Three Gorges on China's Yangtze River.
Hydroelectric power creates no air pollution or greenhouse gas emissions. There are two basic set-ups for hydro: the dam system and the run-of-river system. Dams are used for large capacity hydroelectric plants, while run-of-river systems have small plants with a very minor dam or none at all.The run-of-river system diverts some of the water in a river into a canal that sends the water through turbines at a small generation station.ams are used for large capacity hydroelectric plants, while run-of-river systems have small plants with a very minor dam or none at all.
