Every Little Bit Counts
You might not think that a white background on a website would be an ecological decision, but with millions of people out there browsing the web you should consider that, like rain, one drop might be small, but a billion or so can add up!
Black Google Would Save 750 Megawatt-hours a year
Take at look at Google, for instance, 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. Now take into account that about 25 percent of the monitors in the world are CRTs, and at 10 cents a kilowatt-hour,
that’s about $75,000/year, a goodly amount of energy and dollars for changing a few color codes.
