This rock-bending tech may change clean energy

A new technology that stores energy underground could make geothermal energy more cost competitive with fossil fuels and traditional renewables — and help accelerate the transition to a clean energy future.Geothermal energy: Earth’s core is about as hot as the surface of the sun, and you don’t need to dig too far into Earth’s crust to feel the effects of this heat — temperatures rise by about 80 F for every mile you travel below the surface.This geothermal energy can produce clean electricity by using hydrothermal reservoirs — underground locations where geothermal energy heats water flowing through porous rocks — to create steam to spin turbines.Geothermal energy is much cleaner than fossil fuels and more consistent than solar or wind power. It’s also renewable — the amount of heat generated by the Earth is nearly unlimited.Geothermal energy is much cleaner than…
