Motion-sensor streetlamps dim when no one’s around

The Netherlands’ Delft University of Technology has come up with a seemingly interesting way to save the national grid some precious watts of electricity lately. The University is currently working on intelligent street lamps with motion-sensors that dim to 20% lower power when no one’s around. this helps the grid and the environment too, helping keep out as much as 80% of Co2 emissions away from the atmosphere. Using LED bulbs triggered by motion sensors, these street lamps detect movement, and the begin glowing at 100% luminosity when someone’s around.

An innovative approach to large scale energy saving and environment-friendliness, these street lighting systems are sure to catch on!
