That's no longer really true. A/C units are in the past 10 years getting quite common in the hot parts of Europe now. In the '90s fewer than 10% of households had them in Italy or Spain, but that has jumped to nearly 50% now. People do use it a lot less, though: they are typically individual units, not central A/C, and only used for short periods on very hot days, not run continuously with a thermostat setting.
