I think this whole heat wave crisis has been shocking to the rest of the world to see that apparently Europeans refuse to install AC even in new-build homes and it is causing enormous numbers of deaths. What is the reason for this? Is it just because it's expensive and energy costs are so high? It seems like a basic safety requirement that they are refusing to acknowledge and are now apparently just refusing to go to…
Which bit of Europe are you talking about? Italy and Spain have AC everywhere. Further north it hasn't been necessary until very recently, and now people are fighting in shops to buy portable units and there are going to be loads of permanent installations once things settle down later this year.
Southern Spain may, but it's virtually unheard of up here in Galicia/Asturias/Cantabria. Even many businesses in these parts don't have AC, and our Ourense region has pretty regularly had 40+ C days the last ~5 summers
