Going green step #3: Switching to CFLs

Compact fluorescent light bulbs (CFLs) are more energy efficient bulbs. A 13-watt light bulb is the equivalent of a 60-watt regular light bulb. It's still not the most efficient light bulbs of all; I believe LEDs are more so, but they're expensive. Even CFLs are more expensive but maybe the energy savings will pay off.

Only thing is that the light bulbs contain mercury, and there has been controversy about whether these kind of light bulbs will create an environment problem of a different kind. If you are thinking of switching, you should check out this website, and definitely be careful about how you dispose it in general.
