With fossil fuel sources depleting and global warming on the rise, exploring alternative means of power for humans is a necessary reality. Now, looking to the sky, relying on the wind or harnessing water power are not the only remaining options. Deep within Earth is an untapped source of energy: geothermal energy.

It has been estimated that within the continental United States, there is a sizable resource of accessible geothermal energy – about 3,000 times the current annual U.S. consumption.


Two important reasons this storehouse of energy has not been tapped is that locating the specific energy hot spots is difficult and expensive.
