Would it be possible (at some point) cool aur by pulling heatenergy from it?

Thats an awesome explanation! Thank your very much!
So, from this and many other comments and some independent reading on my side, we‘re technically just walking batteries getting fed by the sun, being buried under ground after dying and becoming coal so to speak.
So, theoretically, we would need to build some way to exhaust the excess heat into space (and could also get work done in the form of electricity) if we wanted to use the current overheating earth to our advantage while cooling it off. Thinking of a giant ac at this point. :D
But jokes aside, this means that the average laypersons idea about „energy“ is false. We need „work“, not energy. Because the dissipated energy can not perform work anymore. Correct?
Sounds like you're on the right track there. As far as energy goes, you're right, when things are dissipated, or all the same, you can't extract anything. You need a differential, like a hot place and a cold one, a high voltage and a low one, a fast object and a slow/stopped one, a high object and a low one. The higher the differential the more you're going to be able to extract. If it's too small you might not be able to get any useful work out at all.
Thanks! That’s good to hear.
