American cities going dark. Detroit is the poster child, 40 percent of the 88,000 streetlights are already broken, but under a new plan half the city is going permanently dark in an effort to get citizens to move. “You have to identify those neighborhoods where you want to concentrate your population,” said Chris Brown, Detroit’s chief operating officer. “We’re not going to light distressed areas". Other U.S. cities have gone partially dark to save money, among them Colorado Springs; Santa Rosa, California; and Rockford, Illinois.
