Geothermal energy developers working on the flanks of an ancient Oregon volcano say they have taken an important technological step toward expanding geothermal energy from a small niche into a potential major source of homegrown power.

AltaRock Energy Inc. of Seattle says the data are still being analyzed, but they are confident they have created three geothermal reservoirs from a single well where none existed before. The breakthrough solves two problems holding back the next level of geothermal development, known as Enhanced Geothermal Systems, or EGS: creating reservoirs big enough for commercial production in places they don't occur naturally, and holding down costs.
