What do light bulbs have to do with carbon dioxide emissions?
When you go home and replace an ordinary 60 watt incandescent bulb with this 13 watt CFL, you will be saving 47 watts for the entire lifetime of the bulb. These bulbs provide the same lumens (or amount of light intensity) as incandescent, but have a rated life of 12,000 hours (15-20 times longer than an incandescent). That’s 564 kWh. That equates with about 1/3 of a ton of carbon emissions saved by this one bulb over its lifetime!
