And you are welcome to try and stay in any of the southern countries of EU in summer and survive without AC - Portugal, Italy, Spain, Greece are all unbearable without AC.
I did say most of the USA. I also am quite confident that the average temperature in the south is much higher then even those countries.
A quick search shows that in Texas the average is 36 degrees while Greece is 28 degrees and 28 degrees in Barcelona. Also that doesn't even include our lovely humidity!
