The conversion to all-electric homes is more recent, and hasn't even started in some places. Here in Canada, some jurisdictions require newly constructed houses and apartments to have electric heat and cooling (heat pump, with resistive heat as a backup), an electric dryer and stove, and an electric water heater (tank or tankless). Others jurisdictions are still using gas furnaces and gas-fired hot water tanks.
