E-cars and other technology have also "hidden" costs, your cobalt does not grow on trees.

Yeah perfect idea using farmland that could be used for growing food wasting on PVs. Do not get me wrong, there has something to happen but perhaps only solar and wind will not safe us as long as we have no good battery technology. Therefore it would be better to store this in some fuel.

Oil doesn't grow on trees either, remember the oil spills we have regularly?

We already use that farmland to grow fuel instead of food, and we also have the technology to store the energy: electrolysis. But because that is relatively expensive you don't want to burn that fuel in shitty tiny generators, you want to burn it in efficient combined-cycle plants.
