This is true, but there other drawbacks. The charging infrastructure may not be there and the electrical grid may not be able to handle the load. Consumers know this and are therefore steering clear of EVs.

I've predicted long ago that EVs will eventually be (much) cheaper than ICE cars since they're much simpler. An EV is basically a battery, an electric motor, four wheels and a steering wheel. ICE cars are incredibly complex. It's just that manufacturers had over 140 years of experience in making them reliable, safe and easy to own and drive.

Even if they become cheaper governments may dissuade consumers from buying them for fear of overloading the electrical grid.
