Coincidentally, this is also the WSJ Morning Brief's Quote of the Day:
"Turning on the light uses the same energy whether there are two people or four people in the room. … If you don't want to get remarried, maybe move in with somebody you like," Jianguo Liu, an ecologist at Michigan State University and author of a study finding that divorce hurts the environment, tells the Los Angeles Times. The study, published in the Proceedings of the National Academies of Science, found that the resource inefficiency of divorced households resulted in an extra 73 billion kilowatt-hours of electricity use in the U.S. in 2005 -- about 7% of total home use -- in turn spewing more carbon dioxide into the air and exacerbating global warming. Other potential solutions, the Times reports, include polygamy, communal living or roommates. "I'm just a scientist trying to present the facts," said Mr. Liu. "I'm not promoting one way or another."
