Inefficiently though.

Electric heaters are only 100% efficient at turning electricity to heat. We can do a lot better than that

I know that in theory a heat pump can do better, but in cold enough climate it can't because one side collects condensation and freezes making it less than 100% efficient. So no, we can't do better.

Use geothermal heat pumps in cold climates.
