In this May 16, 2008, file photo, a worker steps down from the drilling platform at Newberry Crater near LaPine, Ore. After pumping more than 20 million gallons of water into the side of the ancient volcano last year, AltaRock Energy, Inc., says it has succeeded in a key technological step toward turning geothermal energy into a major source of homegrown energy. The company says it created three seperate geothermal reservoirs on a single well in a place where none existed before. (AP Photo/Don Ryan, file)
