No, that's not what I'm saying. Jevon's Paradox has a good Wikipedia page that describes the problem. Efficiency improvements don't reduce consumption in aggregate, because the lower demand causes lower prices that then unlock new use cases that create more demand that pushes up usage again.

As the wikipedia page points out, this assumes a highly price elastic good.

Household energy use is not such a good, because most uses have fixed utility.

Very few people are going to cool their house down to 10C because the price of cooling to 15C decreased.

Nor is their overall energy use budget-capped. (Outside of low income AC and/or heating use cases)

You started by talking about electricity usage, which is fungible and elastic. There's no dedicated grid for household electricity so Jevons Paradox certainly applies.
