Ann Arbor, Michigan, always a town with the latest in tech, has decided to replace about 1,400 downtown street lights with LEDs. They claim to be the first for the conversion which they feel will save the town $100,000 a year, according to Mayor John Hieftje. According to the U.S. Department of Energy, widespread use could cut energy consumption in half. Considering that it only cost $630,000, we hope that other towns will follow suit for the same results.
