234845 story Change Google's Background Color To Save Energy? 519 Posted by CowboyNeal on Friday July 27, 2007 @02:51AM from the turned-off-until-further-notice dept. i_like_spam writes "Recent commentary at Nature Climate Change describes an on-going debate about the energy savings associated with the background colors used by high-traffic websites such as Google and the NYTimes. A back of the envelope calculation has suggested energy savings of 750 Megawatt hours per year if Google switched their background from white to black. In response, a new version of Google called Blackle was created. However, other calculations by the Wall Street Journal suggest minimal energy savings."
