From near the table you linked to:

> the expenditures included for households that heat primarily with electricity in this report would also include electricity used for appliances and lighting

That's not a fair comparison (gaslighting?) unless you use gas lighting, a gas dishwasher, and a gas freezer!

It also doesn't mention what heat pump efficiency is assumed, it just compares electricity "as a fuel" to other fuels, which means resistive heating. Wholly unrealistic for places that need any serious amount of heating per year.

(I was surprised to learn that a colleague in South Africa was cold and couldn't turn on the heater during their winter because they don't have heating installed! A 10€ space heater and some blankets is all they need for heat around there apparently. There, resistive heating makes sense as compared to an expensive heat pump system.)

The amount of electricity used by appliances and lighting is negligible compared to that used by the air conditioner compressor. Even the air conditioning fan is hardly more than a few light bulbs.

So while it's good that the report quibbled, they might have gone to the effort to quantify their equivalent at least to an order of magnitude.
