How does Geothermal Power Generation Work?
Geothermal power generation works by extracting energy from heat deep within the Earth. In some places, such as the islands of Iceland, the Philippines, and Japan, geothermal hot springs are common, making the energy easily accessible. In other places, sufficient heat is only found more than a mile beneath the surface, making geothermal energy extraction impractical. Holes dug about 1.5 km (0.93 mi) anywhere can usually be used to produce geothermal energy.
