Renewable energy is energy generated from natural resourcesâsuch as sunlight, wind, rain, tides and geothermal heatâwhich are renewable (naturally replenished).Renewable energy technologies range from solar power, wind power, hydroelectricity/micro hydro, biomass and biofuels for transportation.his includes sunlight, geothermal heat, wind, tides, water, and various forms of biomass. This energy cannot be exhausted and is constantly renewed. Alternative energy is a term used for an energy source that is an alternative to using fossil fuels.
Renewable energy allows you to tap into natural resources that are replenished as part of the normal life cycle. Cut a tree down to burn for heat, and that tree is gone forever. Tap into the wind with a turbine to generate electricity, and the wind continues to blow. The Union of Concerned Scientists suggests the following clean renewable energy sources: Wind Power. The U.S. can produce more than 10 times its energy needs through wind power, one of the fastest-growing energy sources. Turbines use wind to generate electricity without creating pollutants. Currently, this is one of the least expensive alternative fuel sources available.
