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.
I find something very refreshing in this, reading from Europe where we get told "gas" is the big bad, even threatening to make condensing gas boilers illegal from time to time [0], despite over 95% of homes (in the UK) being heated by this method. I gotta be honest it's just so weird living in such energy poverty in Europe. Most of Europe doesn't heat or cool adequately, Spain and Portugal barely heat their homes in winter and boy it gets cold with 41F/5C nights. Then Germany/Switzerland refuse to use A/C even though the summers get to 95F/35C. Just a few days ago a friend told me he went to the doctor and the doctor passed out during examination from the heat.
