Hydropower

Hydropower is a clean, renewable and reliable energy source that serves national environmental and energy policy objectives. Hydropower converts kinetic energy from falling water into electricity without consuming more water than is produced by nature. Like wind, solar, geothermal and biomass, hydropower is a renewable source of electricity. Water, its "fuel", is continuously replenished by the hydrologic cycle, which is powered by the sun. Hydroelectric projects can enhance wetlands and support healthy fisheries. Wildlife preserves can be created around reservoirs, which in some cases, provide stable habitats for endangered or threatened species. Today's hydropower turbines are capable of converting 90 percent of available energy into electricity - that is more efficient than any other form of generation. Even the best fossil fuel power plant is only about 50 percent efficient. Hydropower's operational flexibility - its unique ability to change output quickly - is highly valued, and will become even more so in a competitive market. Its unique voltage control, load-following and peaking capabilities help maintain the stability of the electric grid ensuring economic growth and a high quality of life.
