Did you know that, according to the Earth Policy Institute, if the United States shifted entirely from incandescent to compact fluorescent light bulbs, we could shut down 80 coal-fired (500 MW) power plants? And that if these changes were adopted worldwide, we’d be able to shut down 270 coal-fired power plants?
Here’s another interesting statistic: Over the life of the bulb, the gasoline equivalent of the energy saved by replacing a 100W incandescent bulb with a 24W CFL is enough to drive a Toyota Prius from New York to San Francisco. Replace two bulbs and you can get back home again. 😉
We did our part last year when we completely changed over to compact fluorescent lightbulbs in our new house (we had previously made the switch in our old house, as well), and I encourage to do the same thing. Not only does swapping your bulbs save a lot of energy, but it can save you a ton of money, as well.
