What difference does a color make?

Google's energy-saving pilot project

As is explained here, in January a blogger noted that white computer screens use slightly more energy than black ones [Update -- only for CRTs, not for flat panels -- see comments].

After a few back o’ the envelope calculations, it was estimated that if the search engine giant Google switched its screen from white to black, 750 megawatt-hours of energy could be saved globally each year.

Fast forward a few months and Google has started a trial of the black-screened search engine – Blackle, found at www.blackle.com. The website also keeps track of how many hours of energy have been saved. When I visited, the number was up to 116,992.364 Watt hours.

Certainly a small, practically mindless, but creative change.

    If you are using a lcd monitor, using Blackle consumes more energy.

    Thanks for this comment. I had been looking for the answer to that specific question. I think the most important points are that if you really want to save energy 1) don’t use a screen saver, 2) enabled the power management features on your computer, and 3) turn off your computer when you’re not going to use it for an extended period of time. Compared to those measures, blackle is drop in the bucket.

    Some very useful tips Joe.

    There is another search engine like blackle called the Carbon Neutral Search Engine but it offsets a minimum of 100g of CO2 per search. The more searches the more carbon offset.

    There are around 25 different versions of “black google” online. The best one I’ve found is http://www.cleanblack.com. Cleanblack is the only version that allows you to change the text colors of the google search results. Try it yourself by going to http://www.cleanblack.com/theme/
