Google to Invest in Geothermal

Google.org is investing a little over $10 million in the development of Enhanced Geothermal Systems, or EGS.

EGS drills deep — miles down — to access layers of heated granite that exist underfoot everywhere on the planet. Water can be circulated downward for heating, and then upward to drive turbines and generate electricity.
