Google Map Reveals Massive Geothermal Potential Nationwide, “Effectively an Unlimited Supply” Says Chu

Southern Methodist University’s Geothermal Laboratory recently released a map that proves once again how much potential energy is locked beneath America. SMU’s resource map, which took years to develop with funding from Google.org, shows that there are enough technically recoverable resources throughout the U.S. to equal 10 times the amount of coal capacity in place today.

Other maps have shown similar data. Last year, SMU issued a map (also funded by Google) that showed massive geothermal potential under West Virginia, an area not typically seen as suitable for the technology. In 2007, MIT Researcher Jeff Tester analyzed deep “hot rock” resources, showing that the U.S has 100 GW of potential for Enhanced Geothermal Systems [EGS] — an emerging type of plant design in which a developer creates an artificial well by pumping water through deep rocks, rather than using direct steam from hot water reservoirs closer to the surface.

So big deal, right? Another map shows we have tons of resources. Why is this so different from the others? Well, geothermal exploration can be a very risky business. It’s not uncommon for a developer to spend 3/5ths of capital on the exploration and drilling phase of a project. And if the resources aren’t there, that’s millions of dollars down the…bore hole.
