Sorry, what? Even charging a battery "require more input energy than available energy from the output". Obviously it's not a source of energy, it's a way to store energy.

And given the notorious low efficiency of ICE motors it's likely that traditional gasoline takes more energy to refine etc. than actually drives the car forwards.
Good point. I agree, framing it as a way to store and move energy from another source (especially a more sustainable source) makes a lot more sense.
