This is the heat that helps cause volcanoes, geysers and hot springs. And it is the heat that powers a modest number of electricity generators around the world, from Iceland to Indonesia.
This energy source remains largely untapped, though, simmering either too far below the surface to reach, or isolated from water that could carry it up. Read more…
