How is hydro power renewable?

Answer 1

The energy from hydro-power actually comes from the Sun. The Sun heat the oceans which evaporate water into the air. This water forms clouds and the clouds produce rain, bringing the water down on the hills. Man dams the rivers flowing from the hills and generates hydroelectricity. Thus as long as the Sun heats the oceans the hydro-power will continue to be available - it is self renewing.

A:It is renewable because the energy source which is water is renewable. water can be replenished by snow or rainfall. That's what makes energy renewable if it can be replenished quickly. A:When we use electricity from hydropower, it is generated by water spinning a turbine in a dam. As long as the rain keeps falling into the dam's catchment area, then the power is renewable, because it keeps coming back, even after we've used it.
