Blackle

By Evan Ackerman

A while back, ecoIron calculated that if Google were to use a black background instead of a white background on its search page, over the course of one year 3000 megawatt-hours of electricity would be saved (assuming that 25% of people are still stuck with CRTs). And that’s the idea behind Blackle. Blackle is a fully functional Google clone, except it’s gray text on a black background. When your monitor displays a predominantly white webpage, it uses about 15 more watts than it does while displaying a predominantly black webpage. Google’s 200 million (ish) queries a day over one year adds up to something like $75,000 worth of energy spent on that white background. Not only does it save energy every time you use Blackle as opposed to Google, but it’s a good reminder that lots of people taking easy little steps to save energy can make a big difference. And, you know, it goes with my nail polish and eye liner.

  1. I particularly liked “Save your eye: blacklys.com uses cool color varitions best for humman eye. How computer harm your eye?” on the suggested alternative. 🙂

  2. You might want to note that Blackle is just the first page of http://www.searchincolor.com, a site which has offered google search in color since a much longer time. There are other color combinations on searchincolor which are energy saving..in general a dark background with light text will save energy over a standard white background.

  3. Some people may find it uncomfortable reading light text on a black background. They might find Greygle to be a better choice for them. It uses a grey background with dark text which they might find easier to read. This still allows for some energy savings while providing an easier reading experience.
