Stay cooler and save money

In the summertime, turning off lightbulbs will keep the room cooler while also saving money. And of course, when we save energy, we are keeping the local (urban heat islands) and global climate a little cooler. If you don't think a light bulb gives off heat, try touching it after it has been on briefly. Even flourescent bulbs will have an effect. I worked in a building where the owner of the building had the janitors turn the lights off at night, unless it was going to be below a certain temperature in the winter, when they were left on, because they added heat.
