@darnell it's not just about saving power & electricity. It's also about leaking gaz that increase climate warming and also, while using the AC, hot air is pulsed out of the house/apartment, which also increase the exterior temperature by +3 or +4°C (especially if everyone in your street/neighbourhood) does that.
I'm not anti-AC, but everyone having one... Is it really the way to go? Is it not better to imagine collective AC, which will provided fresh air in a network?
