The world is on the verge of a geothermal revolution. Until recently, the clean energy technology was only viable in very specific geological areas where the heat from the Earth’s core naturally reached the surface of the planet, as in Iceland’s geysers and volcanoes, but now, with improved drilling technologies, advanced geothermal energy systems could very soon be feasible and affordable virtually anywhere on Earth. And while the sector is nascent, it has some critical advantages over other energy forms, meaning that it could revolutionize…
