Black Is The Colour

Green, eco friendly websites are increasingly gaining popularity, and one clever blogger has calculated the cost of Google's famous white homepage:

"Take at look at Google, who gets about 200 million queries a day. Let's assume each query is displayed for about 10 seconds; that means Google is running for about 550,000 hours every day on some desktop. Assuming that users run Google in full screen mode, the shift to a black background will save a total of 15 (74-59) watts. That turns into a global savings of 8.3 Megawatt-hours per day, or about 3000 Megawatt-hours a year. And at 10 cents a kilowatt-hour, that's $300,000, a goodly amount of energy and dollars for changing a few color codes."
