Yes but people suck
I do agree that better efficiency and simply not spending energy on stupid stuff would be far better,
but con artists will continue to promote crypto, and nobody wants to give up their air conditioner or heating, and business will continue to head down capital intensive/reduced labour automation etc etc etc.. Not to mention former third world countries wanting to be "developing nations" and cremating the environment to get there.
so power demand will continue to rise, and someone is going to make a buck providing it,
Generating and transmitting power anywhere inside the atmosphere is going to leak heat into the atmosphere, but at least most of the renewables are grabbing energy already in the system, so its only manufacturing the collectors and infrastructure plus transmission leakage - and if you can get a granular renewables network with local collectors and storage, you will get less leakage than from massive centralised systems..
The simplest solution to global warming would be to reduce solar input outside the atmosphere - except we absolutely lack the capability to do that. If we could harness environmental heat and convert it to non thermal use - that would be nice... kind of like what a wind turbine does, only it would totally screw up the climate if we did it at significant scale
