At the moment, however, these so-called “clean, firm” sources remain elusive. Recent advances in geothermal technologies, demonstrated by a handful of real-world projects, suggest that harnessing the earth’s heat could be among the most promising ways to solve this clean-energy conundrum. But that can only happen if it can overcome the sizable challenges that stand in its way.
