Could Fracking Tech Be the Key to Tapping Geothermal’s Potential?

Geothermal energy provides one of the cleanest and most consistent sources of renewable energy on Earth. In theory, there is enough geothermal energy under the Earth’s crust to sustainably power the entire planet – so why aren’t we using so incredibly little of it? The issue is tapping into that radiant heat – only a tiny fraction of the Earth’s thermal energy can be accessed profitably. But a team of researchers out of MIT thinks they may have achieved a technological breakthrough with the ability to tap into a whole…
