The Switch to Outdoor LED Lighting Has Completely Backfired

“This study is important because it validates with data two things we have suspected: that the rate of growth of light pollution continues upward on a worldwide scale, and that the migration of outdoor lighting from older technologies to LED isn’t having the anticipated benefit in terms of global reductions in energy usage,” John Barentine, the resident physical scientist for the International Dark-Sky Association, told Gizmodo. “The latter point is especially important because a number of governments have been convinced to convert their outdoor lighting to LED on the basis of promised reductions in energy usage.”

Barentine, who wasn’t involved in the new study, says the cost savings from the improved energy efficiency of LED lighting has been directed towards the deployment of more lighting, and with important environmental consequences both in terms of light pollution and carbon emissions.
