According to some smarter than me IT folks, using a white background on a website sucks up more wattage than using a black background. I would assume that that’s the same as using a word processor with a white page/background all day. Mark Ontkush suggests that if Google were to change their code and present their home page on a black background it could save $75,000 worldwide.
To alleviate the issue, Ontkush redesigned his website with an energy efficient color scheme. Not a bad idea. Maybe I should try the same thing with SSL 3.0.
