Geothermal Energy – An Abundant Resource

Geothermal Energy is energy expelled from the earth’s crust. Derived from magma, molten rock in the earth’s crust, and the natural process of the radioactive decay of potassium, uranium, and thorium. Magma is extremely hot because of the enormous amount of pressure and friction found in the area of the earth’s subsurface. The largest geothermal energy plants currently churn out a couple hundred megawatts of energy. Current estimates state that Iceland can produce enough energy to provide 1700 megawatts of electricity for the next 100 years.
