I'm merely making an in my view commonsense point. ICE engines are carefully regulated worldwide, certainly in any nation which would consider mandating a transition to electric vehicles. Subsidies and gasoline taxes encourage societal transition to make transportation as efficient as possible, without mandating a full phase out of gasoline as a power source.

Renewables have scalability issues. Grid scale renewable energy is possible but needs to be supplemented by either significant on-demand generation when the renewables are offline (at night, when wind is weak), or very large scale battery storage. Localized in-home energy storage is plausible but expensive to roll out. We are also talking about absolutely gigantic demand for raw materials to produce sufficient battery capacity to smooth out the renewable power generation curve.

My point is that in order to feasibly power a society which is heavily reliant on electric cars, power generation via renewables alone is not a viable answer.

> Doing the same for more than a billion ICE engines distributed all over the world is effectively impossible.

Delivering said energy to over a billion cars all over the world is pretty impossible. As things stand right now that's an entire continent (Africa) which in many places doesn't have reliable power even for basic things like keeping the hospitals running (they have to use diesel generators and the like).

But, then again, this EV-vehicle "revolution" is targeted at the Western middle-classes + China, they can afford to not care about the rest of the world as they've done until now.
