Geothermal energy has finally hit the big time. Google.org, the philanthropic arm of Google, announced today that it is investing $10.25 million in an energy technology called Enhanced Geothermal Systems (EGS). The funding will also go towards geothermal resource mapping, information tools, and a geothermal energy policy agenda.
And it looks like Google made a wise investment choice. According to an MIT report on EGS, only 2% of the heat beneath the continental US between 3 and 10 kilometers (depths we can reach with current technology) is more than 2,500 the annual energy use of the United States.
