Here there's a term regarding moving emissions from the exhaust to the outlet.

Although our energy infrastructure is massively moving towards greener/renewable (solar, wind, hydro, all of which we have a huge amount of) the reality is right now ~65% of our electricity is coal. So it's only 1/3 "clean" (I guess better than 0/3 of petrol?). The coal plants all have a plan for decommission though, and no new ones are being built (despite us having so much coal we can basically never use it all).

With that said though; that electricity will be generated regardless of use right now (as electric vehicles are such an insignificant number of cars on the road they're not even a rounding error so certainly don't impact the volume of electricity generated) so you can consider them clean as they're not adding to emissions that wouldn't already be generated, however are removing the exhaust gasses of a petrol vehicle.

It's the future though, whether you like it or not. I bought a new car, picked it up on new years eve. I had the decision between petrol and electric (model 3 performance was my electric choice). I went for petrol driven, however I am well aware my next car will be electric and I figured no matter which car I got I'd only keep for 3-3.5 years max.
