Global warming happens because CO2 magnifies our energy input by orders of magnitude. The temperature change caused by the actual energy we use is completely negligible. The part that counts involves magnifying the sun’s influence. There’s no equivalent to that for geothermal power. The energy you extract is the energy that’s lost, and that’s it.
