Experts Say Geothermal Can Work in Much of U.S.

November 9, 2011

One renewable energy resource that is drawing increasing attention is geothermal. As technology for using geothermal energy improves, the areas that can provide this form of power are expanding.

Researchers at Southern Methodist University, funded by Google, have estimated relative geothermal potential in the US with a new map that is based in part on newer data drawn from oil and gas drilling operations. The results underscore the known good potential in much of the western US, and also note good prospects in parts of the Appalachians (particularly in parts of PA and WV), as well as substantial areas in TX, LA, and MS. Google says the newer geothermal technologies that are being explored in the US and a number of other countries suggest there may be decent geothermal prospects in all 50 states. If the new and old technologies pan out, various experts are saying geothermal could supply a very large percentage of all US energy demand.

For the Bureau of Land Management and US Forest Service perspective on US geothermal prospects (with the focus on the western US), see:
