> By one recent estimate, more than 5000 gigawatts of electricity could be extracted from heat in rock beneath the United States alone. That’s nearly five times the total currently generated by all U.S. power plants. So it could provide all the US' energy needs for five years? In some ways that sounds...unimpressive? Or more like, "okay that would be cool for a little while, but then it runs out and you're at square one", as opposed to solar/wind which are renewable, or nuclear where there's tons of uranium that could be used.
