By sifting through oil and natural gas drilling data, a Google-funded study found that geothermal power in the U.S. could produce ten times the capacity of coal plants today.
The Geothermal Laboratory at Southern Methodist University yesterday revised estimates for the country's potential to use underground heat to make electricity. Drawing on geological data from some 35,000 sites as deep as 31,000 feet, the study concludes that geothermal could supply a large portion of U.S. electricity needs in the future.
Most geothermal power plants are located in western states where underground temperatures are higher. But … Read more
