The folks over at Climate Feedback report that even one color of your computer screen may consume more energy than another. In which case, go to the dark side, as reportedly a white screen such as an empty Word page or the Google page uses 74 watts to display, whereas a black screen consumes only 59 watts. Apparently, Mark Ontkush who has time on his hands to calculate this for the rest of us reported in his ecoIron blog.
Actually, Google does have a black version of its front page called Blackle which reports how many watt hours it has saved. Others like the Wall Street Journal have challenged the claims of energy savings through Blackle.So, if you want to do your own calculations and still save energy, use a pencil and a piece paper from your recycle bin. If you want to redesign your web page using more energy efficient colors, you can browse suggestions from Jon Doucette of Jonathan Design also on Mark's blog.
