That was the point of my post so thanks for contributing some interesting comparisons of your own. BTW, I was thinking of that shocking nighttime satellite photo of the Korean peninsula that you mention as well as the fact half of N. Korea's residents don't have electricity at all. For many of the rest there are daily rolling blackouts and some only get power for one hour a day to cook dinner (https://en.wikipedia.org/wiki/Energy_in_North_Korea). Also, Arizona and Florida State Universities, the two largest in the USA, are in extremely hot climates. The HVAC consumption alone for all those classrooms, common areas, facilities and dorms must be massive, whereas electric HVAC is virtually unheard of in N. Korea.
