"For 25 years I've been telling people to turn the lights out when they leave, to no avail. Then I was at our High Point, N.C., operation, where the managers had divided employees into four teams and given each team different categories of our profit-and-loss statement. The team responsible for occupancy costs said, 'We could save money if we shut the lights off.' Now, the lights are off whenever they're not needed. As soon as the employees realized they could save money by shutting the lights off, they started to shut the lightsoff."
