Just looking at my street, which is not old infrastructure, they would have to replace all the electric lines, all the transformers, and all the panels in all of the houses if everyone here decided to have EVs. If everyone went to 100% electric heat, it would be even worse.
We have dual fuel heating (heat pump, oil burner). It's prohibitively expensive to run the heat pump below 32F (0C), but the oil works great then, and is way cheaper. Just like the heat pump is cheaper at warmer temps. The heat pump won't work at all at 0F (-18C), so it's a non-starter to only use air based heat pumps for all of our needs. We've tried to get quotes for geothermal, but we'll just have to wait for the next big recession to do that.
As an engineer, I just have to shake my head at the unrealistic timelines being pushed by politicians. All that does is increase cost and drama.
