According to the U.S. Department of Energy, LED lights could help communities save more than $750 million per year in energy costs, while also offering benefits like more uniform light distribution. Around the world, LEDs are lighting streets from Torraca, Italy, to Toronto, Canada, and from Tianjin, China, to Sydney, Australia.
Yet, in the big picture, the Clinton Climate Initiative report notes “negligible” adoption of new lighting technologies by cities. When cities do seek to cut energy costs by converting old streetlights—many of which are non-metered and owned by the local utility—they often encounter a rocky road ahead.
