I am of the opinion most of this heat is not as a result of burnings, climate change itself is a normal and expected phenomenon. Let's not do as if we don't know. There are bigger factors governing these things beyond our generators and cars. That theory may need some revisiting in the nearest future tho.
But yes, we can only do what we can within our scope of knowledge and what we are influenced by. A guided action may never be achievable. All you suggested are too ideal to come to pass. Generators will keep being used, so will cars. Will batteries offer better?. Oh no, pollution too

All of it is as if there is nothing we can do able it. This is why we advice survival and preparations for things like this. Knowing the powers that be a greater than our.

Don't mind how I sound, but on the long run, I hope more people see it this way and do the needful they can to make things better for the common men with their power.
