Are Sun Belt cities more energy efficient?

Maybe, says a study by a University of Michigan researcher.


In a new study comparing climate control in Miami (the warmest large metropolitan area in the U.S.) and Minneapolis (the coldest), Sivak found that heating the Twin Cities area is about three-and-a-half times more energy-demanding than cooling Florida's largest urban area.…

"To the surprise of many, air conditioners are more energy-efficient than furnaces or boilers," he said. "It takes less energy to cool down an interior space by one degree than to heat it up by one degree because it takes less energy to transfer heat (air conditioners) than to generate heat (furnaces and boilers)."

Sivak's study is published in Environmental Research Letters. It can be downloaded at:http://iopscience.iop.org/1748-9326/8/1/014050/article
