Cars are a very unimportant part of changing to clean energy.

The most important part is the generation. Making specific types of cars required right now is VERY premature, and will just cause backlash.

Let's focus on just one (main) thing: Clean generation of electricity. The rest will come in due course.

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.
