North Americans mostly do not use electricity for heat in the winter. Around 60% use natural gas with forced air furnaces. Something closer to 80% have the option, but 20% don't bother to use it.
Some of the deep south get by with electric heat, but they aren't in places where the cold is a typically a legitimate danger to health and safety.
