A limitless supply of heat exists beneath our feet within the Earth’s crust, but harnessing it at scale has proved challenging. Now, a combination of new techniques, government support and the pressing need to secure continuous clean power in an era of climate crisis means that geothermal energy is finally having its moment in the US.
Until recently, geothermal has only been viable where the Earth’s inner heat simmers near the surface, such as at hot springs or geysers where hot water or steam can be easily drawn to drive turbines and generate electricity.
