Conserve.

The future of our planet is bleak if we don't make some changes. Every little bit makes a difference, even changing incandescent lightbulbs to compact flourescent lamps.

So far, over 16 million bulbs have been purchased, which is the equivalent of keeping over 100,000 cars off the road. Since the average American home is responsible for twice the greenhouse emissions as a car, these bulbs are an easy way to make a dent in our carbon footprint.
