Copenhagen gives everyone else an inferiority complex. Because they just have it so… well… together. 
The city is working on expanding a wireless  network of streetlamps and sensors aimed at saving money, cutting the use of fossil fuels and easing mobility- all with the goal of becoming the world’s first carbon-neutral capital by 2025.
Sounds cool but what does this network actually do? Well, truck drivers can see on smartphones when the next light will change so they can vary their speed to avoid idling. And, using sensors, streetlights brighten when vehicles approach. After they pass they dim. And there are a lot of plans for it in the future.

The New York Times looks at Copenhagens big plans for lights.
