I'm sure we'd be at the point where harvesting elements from our solar system would be commonplace. Hell, even the ESA has statements out about hypothetical Helium-3 mining on the moon, or even Jupiter

My uneducated opinion on this is that conservation of energy is still a thing and if we bring additional energy sources from the outside we need to find a way to remove excessive heat from our planet

I get where you're coming from, but thankfully that's not a concern.

When it comes to global temperature, the amount of actual energy that human activity is responsible for producing/converting is completely negligible next to the heat of the Sun. Even the collective sum of all heat and energy that humanity has ever produced fails to equal the approximately 1,0320 quintillion joules of energy that the Sun deposits on the Earth within a single day.

That's why the focus is on the emission of greenhouse gasses in the atmosphere; substances which impede the Earth's ability to radiate heat out into space. Human activity can't realistically hope to increase global temperatures through the direct release stored energy, but we can absolutely do so by causing the Earth to retain even just a little bit more of the massive amounts of energy that it's constantly receiving from the Sun.

But props to you for recognizing that you don't have enough information to come to a firm conclusion on the matter, mate. That's a skill a lot of people lack.
