Enhanced geothermal systems can provide clean energy in areas where conventional geothermal systems are not viable. This Review discusses energy production through these systems and the technological developments that could enable its future expansion.
No it wasn’t. At least not by scientists. The math is very clear here.
Also, like how we can pump the heat out…
We can pump the heat back in too. It works both ways, and resistive heating is pretty much 100% efficient.
