Congratulations! Your home just used as much electricity in a month as the average Brazilian or Mexican household in a year; both countries are hotter than the "hot" places commonly cited in this thread, Texas and Florida.
For 4 months of the year, I live in a white wasteland of below freezing daily, and for two of those months, it's pretty much at or below 0 every single day.
And that doesn't really bother me all that much, I'm used to it, and I set my heat to like, 60, and don't even notice.
But for about two months every year, my area hits the low 90s, with near 100% humidity, and being so used to frigid, cold weather, people around here just cannot tolerate that. We can't get used to it, because it doesn't last long enough and the other extreme happens more frequently, and for longer. So when summer comes, we have a hard time adjusting and so most people around here basically require an AC to function.
People in Brazil and Mexico are not only used to hot, humid weather 24/7, but they also have proper clothing for it, homes built for it, and pretty much an entire way of life around it.
Around here, we just put our snow shovels away in April and a week later it was 85. There's no adjusting to that. Our homes, our clothing, cars and lives are all adjusted around extreme cold and snow. Because to us, that's the much bigger part of our lives. So when summer rolls around, we don't know how to handle it without AC. The average AC setting in my area is 70 degrees. People in Texas would probably think that was basically freezing. And yet that's where my fellow western New Yorkers are most comfortable.
