Powered heating is a fundamental human need in Minnesota. You cannot survive without it. Even in antiquity I can't imagine people surviving without fire. Passive cooling, by contrast, is pretty much adequate (though that's not to say the heat can't kill you if you're out in the sun.) But in any case, when you look at the amount of energy expended on heating, the modest amount expended on cooling is a natural expenditure. I think in general that's why a lot of colder countries like Norway are more rich and prosperous than their warmer counterparts. When it costs $30,000/year just to survive, luxuries start to become a lot less costly as a percentage of income.
