Every car switches to electric -> this is happening, but it takes 5-10 years to phase out a car. If 100% of new car sales are electric, we’ll have to wait until 2030. But we’re not at 100% yet. So we’ll probably only get there around 2040-2050.

Every house switches to non-gas water heating and climate control -> this one takes even longer, 10-20 years to phase out. It’s probably easier to get to 100% clean new sales

Every industrial process switches -> I don’t know enough to even speculate but this sounds like an even longer CAPEX cycle

Every plane & ship switches -> we don’t have the tech for this figured out yet. Ships are probably one of the biggest things we should switch over ASAP.

Every powerplant switches to nuclear/solar/wind/hydro: another multi-decade project.

I want all of the above, if only for cleaner air for health reasons, and because I’m an engineer and nuclear + electric seems more elegant. But it will take a very long time.
