EVs are 3 to 4 times more efficient than ICE vehicles. So just converting to EVs is a huge efficiency gain. In fact, if we electrified industrial and transportation using existing technology we could reduce energy demand by up to 40%. And as you recommended, power generation from solar (where/when feasible) removes the need for ongoing fossil fuel purchases.

That 40% number is impossible. First of all transportation is 30% of energy, which already makes 40% impossible, second if it's 4 times more efficient then it would still use 8% to 10% of energy, making your actual savings 20% of energy at the MOST.

But your 3 to 4 times number is also not real, because the actual number is 2 to 3 - and that's measured at the outlet, if you measure starting from primary power generation they are about 2 times as efficient, not 4.

So I stand by what I said: Electric vehicles are not what matters for clean energy, what matters is power generation.
