Lmao. We do need ac though, the problem is Europe has a ton of older houses which were build when it was much more beneficial to try and keep warmth in rather than out. And it’s a pain in the ass to retrofit all these houses with ac. I live in a flat which was build about 15 years ago and the difference compared to my previous apartments is enormous. Still no ac, but it’s not needed here because of proper isolation and smaller windows.
That assumes you have bought you own house which you can alter. Where I live it’s 60% owns and 40% rents, but the cities, where it’s much warmer and which heat up faster and thus need ac the most, have more renters than buyers. So you’re dependent on whoever you’re renting from to do anything like that.
