This hadn't really been on my radar:

"Just one type of next generation geothermal — called superhot rock energy, where deep drilling reaches temperatures 400 degrees Celsius (752 degrees Fahrenheit) or hotter — is abundant enough to theoretically fulfill the world’s power requirements. In fact, just 1 percent of the world’s superhot rock potential could provide 63 terawatts of clean firm power, which would meet global electricity demand nearly eight times over."

What's absolutely fascinating to me is the idea that fracking techniques could be used to unlock geothermal energy. Is that good? Fracking has negative side effects that go beyond the carbon footprint from oil and gas. On the other hand, of course, moving away from fossil fuels is obviously great. #Climate
