Copenhagen Lighting the Way to Greener, More Efficient Cities

Aimed at saving money, cutting the use of fossil fuels and easing mobility, the installations are part of a growing wireless network of streetlamps and sensors that officials hope will help this city of roughly 1.2 million meet its ambitious goal of becoming the world’s first carbon-neutral capital by 2025.

On a busy road in the center of town here, a string of green lights embedded in the bike path — the "Green Wave" — flashes on, helping cyclists avoid red traffic lights.

On a main artery into the city, truck drivers can see on smartphones when the next light will change. And in a nearby suburb, new LED streetlights brighten only as vehicles approach, dimming once they pass.
