Not sure if I posted this one before, but if you want to save energy, use Blackle. Blackle was created by Heap Media to remind us all of the need to take small steps in our everyday lives to save energy. Blackle searches are powered by Google Custom Search.
Blackle saves energy because the screen is predominantly black. A given monitor requires more power to display a white (or light) screen than a black (or dark) screen.

Unfortunately it doesn't actually save any energy:

Shh, don't tell that to environmentalists; if they don't find a way to ease their Western guilt, they become angry.
Um, in an LCD screen, the backlight is always on, the white light is just obscured by a completely darkened pixel. The site probably uses more energy--it has to flip a pixel (completely on for black) on and off each time the monitor scans.
This could be true for CRT monitors, but it's probably negligible, most of the energy used by those is in heating the cathode.
