Kind of a red herring when even 100% fossil fuel power is far more efficient than a car engine. Many US states are projecting <5% fossil fuel reliance for the grid within 15 years.
From what I’ve read it’s about 50% emissions pound for pound based on the fuel mix in the North American grid. Which is fucking great! It’s a bit of an issue that the best selling EVs in the US weigh more than twice what a small ICE vehicle weighs. Which, washes out all the advantage. but the grids gets cleaner over time so perhaps they end up on the right side of things by the time the vehicle is retired.
It’s not a red herring, it is a fact and forgetting it is why the fucking EVs got so damn big. TODAY, a compact ICE, is about a wash with a big ev truck in North America and a hybrid drive or small EV is the way you actually cut your carbon output.
Doing some back of the napkin math, that sounds about right. The problem with saying, “don’t forget EV power comes from fossil fuels too”, is that it implies an equivalence between the two. They aren’t equivalent, a 50% reduction in carbon emissions is fantastic. Moreover, as you mentioned, EVs will improve their emissions in lockstep with improvements in the grid.
I agree we should move towards smaller cars on average. However, I think this is simply the car buyer preferences of today. The most popular ICEs are also big heavy SUVs and trucks. People who are shopping for big EV trucks want big trucks regardless of the powertrain type. They were never going to buy a small compact car, so it doesn’t make sense to make that comparison. You have to compare like-for-like.
With a like-for-like comparison, EVs aren’t nearly as dramatically heavier as many people say. Some examples:
Average out a ton of models, and it comes out to 10-15% heavier for an equivalent EV model. Add in that most EVs are more aerodynamic and EVs require a very similar amount of energy input to push them around.
