Can't talk of heatpumbs, but EVs are great. Been two years being an all EV family. I still don't see enough curb side opposition for people without drives. Home charging x10 cheaper than dino juice, but public chargers (80p per kWh), are basically the same cost. So without home charging, there is little to no cost saving. Which is not only unfair, but will slow EV adoption.

Some people still complain about slow charging on EVs. Most electric cars have no problem getting 3.5 miles per kWh. A standard UK wall plug can safely provide 13A, and while the voltage is notionally 230V it's actually more than that for most people, but even if we ignore that, 230V × 13A ≈ 3kW, so an overnight charge of, say, eight hours on a standard wall plug gives you 3kW × 8h × 3.5mi/kWh ≈ 84 miles of range for under £5 if you pay 25p/kWh. I've said it before; if you can afford an electric car, you can't afford not to have an one.

Space is the stinker, of course. A lot of people don't have a spot on their property they can park their car, but for those that do it's a no-brainer.

Also, heat pumps are basically magic. Why they're not mandatory on new-builds, I don't know.
