An electric heater is inefficient if the electricity was generated inefficiently.

Inefficient: burn methane at a central point running a steam engine generator, dumping tons of waste steam into the air, run the electricity to your house and turn it into heat there.

Efficient: pump methane to your house and burn it there.

More efficient: burn the methane at a central location running a steam engine generator, carry both the steam and the electricity to your house, heating it and running appliances.

The moral: live densely enough that steam pipes are practical.
