Being green is good! Wait a minute, maybe not. Milwaukee, Wisconsin, has experienced a green problem. They replaced all their traffic lights with LED bulbs. Unfortunately, the bulbs don't emit enough heat to melt the snow, and the lights get so much snow build-up that they can't be seen. The result? Dozens of automobile accidents. But the important thing is we're conserving energy!
