Energy-efficient light bulbs increasing light pollution, new study suggests

Over the past four years, the artificially lit surface of Earth at night increased by two per cent annually, or 9.1 per cent in total.

John Barentine, program manager at the International Dark-Sky Association out of Tuscon, Ariz., said the findings aren't a surprise.

"It's not just a problem of the West... we're really seeing it all over the world," Barentine, who was not involved with the study, told CBC News.

"When something becomes less expensive to produce, we tend to use more of it than less," Barentine said. "Some of us had this suspicion that maybe all these cost savings of the better energy efficiency of lighting may just be ploughed back into buying more lighting...and that seems to be what's happening."
