Actually, I think gas->electric is the easier one quite frequently.

Simply because adding vent fans can be a physical impossibility because there's nowhere to vent to. There's more living space on the other side of the wall (in your building or an adjacent building) so you can't vent directly outdoors, and there's no duct so you can't vent anywhere else either.

I'm not an electrician so I can't speak to the cost of upgrading -- but it sounds like that might be required for widespread adoption of EV charging anyways. So if transformers are being upgraded nationwide anyways, then supporting electric stoves might come for free.
