Helium isotopes point to the best sources of geothermal energy

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

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