I think geothermal can be part of a solution, as can solar, and nuclear, and wind, etc. We need all hands on deck here. I think you're not wrong to worry about

I think geothermal can be part of a solution, as can solar, and nuclear, and wind, etc. We need all hands on deck here. I think you're not wrong to worry about cooling the interior of the Earth too much, but that's a much slower problem we would have plenty of time to adapt to. Millions of years is longer than humans have been a species. Given all the other very viable energy options out there, I don't see us overdoing it on the geothermal front. Global warming on the other hand is going to fuck us up over the next century. One thing I would like to see happen is tap the energy at Yellowstone in a big way. We want to cool that down before it blows up in our faces.
