Geothermal Energy

. Basically Geothermal energy is energy that emits from the earth. It comes from magma and the radioactive decay of uranium, thorium, and potassium. Magma is hot because of the tremendous amount of friction and pressure to be found in the earth's subsurface area. Geothermal energy, while massive in total, doesn't do too well when compared to the amount of energy we get from the sun, which wins by a factor of about 20,000. Nevertheless, geothermal energy is tapped by over 20 countries, most notably Iceland, which gets 17% of its electricity from geothermal energy. The largest geothermal energy plants output a couple hundred MW (megawatts). It has been estimated that Iceland has enough geothermal energy to provide 1700 MW for over 100 years.
