New Green Jobs

Some Wisconsin communities have switched out their old traffic lights for new LED lights that use less electricity.

However, they are discovering that the energy-saving bulbs are a hazard in a snowstorm. They use less electricity, but don’t give off enough heat to melt ice or snow. So when the snow falls and the wind blows, the traffic lights are obscured. And it's caused traffic accidents at intersections where drivers aren’t sure whether to stop or go.

But don't fear--it's created new jobs for public works crews who now have to manually scrape the ice and snow off the traffic lights.
