Geothermal energy is taking off - here's why

Miles below the Earth's surface, there's enough thermal energy to power all of humanity for the foreseeable future. It's called geothermal energy, and it's poised to play an increasingly large role as a source of always-available, renewable power. There are a number of startups in the geothermal space working to figure out how to access this heat in difficult-to-reach geographies, at a price point that makes sense, and they're looking to the oil and gas industry for funding and support.
