necro81 writes "Little known even in environmental circles is a renewable energy success story: five geothermal power plants on Leyte Island in the Philippines — each of which produces enough power for the entire island — that collectively produce more than 10% of the Philippines' total electrical demand. From boreholes deep underground comes pressurized water heated to 280 Celsius. At the surface it flashes into steam, turning one set of turbines, then cools and contracts to spin a second set of turbines. The low-grade steam is then condensed back into water and reinjected into the bedrock. But Typhoon Haiyan destroyed the cooling towers, snapped transmission towers, and scattered the employees."
