Geothermal has the potential to provide up to 90 gigawatts of electricity in the U.S. annually by 2050 , according to theDepartment of Energy .

Fervo did not respond to a postulation for comment at the time of issue .

Given the high cost of geothermal boring , which has to manage with strong rock than that encountered by rock oil and gas rig , it ’s likely that Fervo will utilize its new return to continue drilling more well to meliorate its stop number and drive down toll .
