 * Geothermal Energy

What is geothermal energy? **  This type of energy uses the Earth's internal heat to generate electricity. Long pipes are sent down into the earth from power plants. Once these pipes hit a geothermal reservoir, the steam shoots up and turns a turbine. The turbine turns a generator and thus elecricity is made. The steam is condensed and piped back down into the deep earth. Geothermal energy is green and is a clear alternative to fossil fuels.

Geothermal energy is an alternative to fossil fuels. Fossil fuels are scarce. The world's oil reserves are low and we need a new source for electricity if we want to continue on with our daily lifestyles. Geothermal uses steam and heat, both renewable resources, to generate electricity. Geothermal energy his almost limitless. That means almost limitless electricity if it is more widely used.
