And advanced geothermal. Fervo Energy let's us get energy that's not based on burning fossil fuels but is, instead, able to produce energy from the ground.
Remove energy from the ground. I wonder what the consequences may be once we are cooling the underground at several MW/h.
Earth will be swallowed by the sun before humans could make a dent in the earths core temperature.
The core is obviously not in question here, but at scale and long term it could have an impact on the water bed, vegetation, underground ecosystems, soil stability, etc.
