Hot cities more sustainable than cold ones, study says

When it’s hot outside, people crank up air conditioners that usually suck electricity from coal- and natural gas-fired power plants at the root of human-caused global warming. This seems like a recipe for disaster, but it’s more sustainable than living in a cold climate and cranking up the heat, a new paper suggests.

“The traditional view that living in hot desert areas is not sustainable should be re-examined,” Michael Sivak, a research professor at the University of Michigan, Ann Arbor, told NBC News. “Because my data suggest that from this point of view — mainly a climate control point of view — living in very cold areas is less sustainable than hot areas.”
