What about the Heat?

Let's assume fusion is available to everyone, anywhere, at all times. "Green" energy from A to Z. Things are jolly, no more green-house gases, no more radioactive Cs-o-Sr that replace the potassium-o-Ca in our bodies, thus having us radiated... But... every form of energy, as far as we know (which, despite all the fuzz, is not a lot), eventually ends up as heat. The motion of atoms and molecules. Can't stop it, can't prevent it.

How one gets rid of heat w/o causing another form of green-house effect? We've solved one issue but introduced another. We've made available "free & green" energy to everyone, thus enabling rise in consumption but then - what about the heat?

The question goes beyond...the ask. Once we solve a given problem, the solution itself mutates into another problem, harder to solve and sometimes the solution resembles the suit juice that the hungry fly dreamt about...

Everybody wants to have the greatest and best of talent but does one know how to keep it content, engaged, challenged? W/o the fakery, propaganda and "we are family" cr/\p? Most want to be billionaires, but strangely, few are willing to have the life of one - with all ups`n`downs. And there are lots of downs. Especially once you've gotten the "ups". At certain points, we've all imagined living the "high" life, having big houses, fancy cars, fans, being "recognized" and "validated" & etc - but have we taken into account what it takes to maintain those? Or... we think, "Am a BiLi baby, will hire people to figure it out for me!"? Cool, but people can figure out only so much. And... still, what about the heat? It gotta go "somewhere". Say in space but... when the rate of generation becomes higher than the rate of dispersion, then what? We still got just 1planet...
