Heat pumps sounds like a good way forward. I haven't looked into the cost to replace a heater in a home, but I guess new homes could just have them installed by default.
What about natural gas use in home cooking/restaurants? Surely, you can't just replace that easily.
EDIT: And what about heating water? I mean, natural gas is used for more than heating the space in a home.
Surely you can. Modern electric stovetops use infrared radiation from a wire coil to heat cookware. The stovetop is covered with a ceramic that allows infrared radiation to pass through, and if you put something on it, it'll absorb the radiation as heat. The technology is also scalable to industrial applications.
I'll let Brown Jacket Man explain the principle. https://www.youtube.com/watch?v=ff04ecF9Dfw
(edit) My house has an electric water heater that was built in the Soviet Union. It uses a ~200-litre tank with a large heating element inside.
Those ceramic/glasstop ovens are shit. An old school coil will always be better, or modern induction.
Don’t confuse the old school glass flat tops with the induction ones. They use different methods and work very differently even though they look alike.
