...AND CHEAPER...:

How 'smart' street lights save energy (Charles Kennedy,  November 5, 2013, CS Monitor)

The intelligent streetlight system, designed by  Dutch Delft University of Technology, using motion sensing technology that automatically dims streetlights to 20% power when no pedestrians or vehicles are in the vicinity--and the idea is ready to go commercial.

Europe pays over $13 billion a year powering streetlights, and this massive sum accounts for more than 40% of government energy bills. From another perspective, we're talking about 40 million tons of CO2 emissions annually, equal to that of 20 million cars.
