How are you not getting that the sun does give unlimited free energy? :) Study it if you don't believe me. You pay for KWhrs of energy to utilities energy companies, I guess.
The KWhrs coming from the sun are worth even more, because those add to Earth instead of subtracting from it.
Ask yourself why you don't believe that the sun gives limitless energy for free, limitless as far as our human lives go anyhow.
You won't be able to find any physical proof of that because there is none. But there is plenty of proof to show otherwise, I've written over 350 stories about it now, all from my own experience and understanding of physics.
Economics is not physics, but it should be, this is part of the problem, we have to bring money into line with the way energy actuallly works.
Further, profit has to go. It will go when we make the required move.
After that it doesn't matter what you might want to do, as long as isn't something deliberately intended to cause damage, instead of causing damage by all the things we do accidentally, they become things that actually benefit the environment by putting more of the energy of the sun to use as things other than heat.
See how it works now? It's the opposite of how it used to work on fossil fuels, we literally can't use enough of the energy of the sun.
Our jobs, after we make the move, and it will happen very quick due to the feedforward effects ("Multipliers") that apply to each case of energy use, mathematically negative to mathematically positive, like lightning breaking down, cascading avalanche effects, the switch will be very rapid, we will look back and wonder why the hell we never did it before. Short answer is profit, it's a pretty serious addiction, fatal if we let it get it's way.
