This isn't obviously true even with a cursory glance at the statistics (https://en.wikipedia.org/wiki/List_of_countries_by_electrici...). This isn't the forum to fire off false one-liners.
- in Italy only very few have electricity to heat
- A/C is still not that common
- BEVs are still not common at all
While in France electrical heating is definitively common, albeit not the sole source of heat for most.
Essentially: I think such data need much more proof on how they are collected before being trusted.
6kW is the minimum you can get, the cheapest offer, but it's mostly a city thing. Not so small apartments are 9, old homes with new contracts vary from 9-12 mono or 36 threephase but while I have no general statistics that's still pretty common in the "countryside".
