Google.org, the public-spirited division of Google.com, charged with addressing “climate change, poverty and emerging disease,” is using the backdrop of the National Clean Energy Summit here in Las Vegas to announce a new round of clean energy financing.

The technology differs from “traditional” geothermal in that rather than exploiting existing wells of earthbound steam and hot water, 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.
