Hydro-electric energy: Today, the energy from falling water is used mainly to drive electrical generators at hydroelectric dams. As long as snow and rainfall can fill streams and rivers, moving water can be a renewable source of energy.

Geo-thermal Energy: Geothermal heat has been used to heat homes and businesses on a commercial scale since the 1920's. In most cases, communities take advantage of naturally occurring geysers, hot springs, and steam vents for domestic heating and in some cases to turn high-speed turbines that drive generators to produce electricity.
