The question that needs to be answered is, what is the marginal impact of taking an ICE off the road and replacing it with a BEV? Using the current mix of renewables is a form of double counting. No more renewable energy is being fed in to the grid, however more is coming from dirty sources. Reductio ad absurdum, what happens if all of Germany's cars were BEV overnight? I've seen estimates that the load on the grid would be increased by 20%. Surely you'd agree that using the current mix of renewables would no longer make sense calculating their environmental impact. So why does that change at the margins? The answer is that it doesn't. The math is the same. With the exceptions we've both pointed out.
