In many US locations we use gas heat instead of electric. It’s far more efficient to burn fuel for heat instead of burning fuel for electricity and then converting that electricity to heat.
US building codes are also increasingly strict about insulation and energy efficiency. Premium home builders go even further with insulation. In some locations, new houses are so well insulated and sealed that extra fresh air heat recovery units are necessary to exchange the indoor air.
