Are Volcanoes the New Source of Geothermal Energy?

Here’s a scary thought: scientists are testing the idea of pumping water into the sides of a dormant volcano in Oregon at pressures great enough to evoke small earthquakes. Why? Apparently, the boiling bowels beneath our feet hold tremendous promise for geothermal energy.

According to a report MIT submitted to the Department of Energy, two percent of the heat some six miles below the ground could provide 2,500 times as much energy as the country currently uses. By employing a technique called Enhanced Geothermal Systems (EGS), several million gallons of water are blasted at high pressures through artificial wells over 10,000 feet deep. When the water reaches the hot rocks, it returns to the surface through a second well as scalding hot water, where its heat can then be harvested for power.
