Approaching global energy crisis forces scientists to search for alternative energy sources elsewhere. Now, some geologists are trying their best to obtain geothermal energy by drilling into the Earth’s crust.

Energy Search Goes Underground
Aug. 6, 2007 — A magnitude-3.4 tremor on Dec. 8 in Basel, Switzerland, was no ordinary act of nature: It had been accidentally triggered by engineers drilling deep into the Earth’s crust to tap its inner heat and thus break new ground — literally — in the search for new sources of energy.
After more, slightly smaller tremors followed, Basel authorities told Geopower Basel to put its project on hold.
But the power company hasn’t given up. It’s in a race with a firm in Australia to be the first to generate power commercially by boiling water on the rocks three miles underground.
On paper, the Basel project looks fairly straightforward: Drill down, shoot cold water into the shaft and bring it up again superheated and capable of generating enough power through a steam turbine to meet the electricity needs of 10,000 households, and heat 2,700 homes.
