"Change a bulb. Change Everything."
That's the inspiration behind Yahoo!'s 18seconds.org. CFL (compact fluorescent lamp) light bulbs use about 1/3 of the energy of regular bulbs, and can last up to 10 times longer - potentially making huge dents in electricity usage and reduction of waste if they're widely used. Find out the live numbers on just how widely they're being used in your city or state on 18seconds.org.
Besides just straight numbers of CFLs bought, they also present some staggering equivalency statistics based on the environmental impact the use of those CFLs would have. You may be surprised to see how big of an impact you can have with such a small change. Considering that the time it takes to swap out your energy-sucking light bulb for a CFL bulb hovers around a cool 18 seconds (cue collective "ohhh"), what's your reason not to?
