Google Should Go Black To Go Green
There are certainly a lot of assumptions in there, but an interesting read nonetheless. Perhaps the funny thing is that this site, which will undoubtedly find itself getting hit a few hundred thousand times isn't very black. It is, in fact, rather white for most part. Let's assume...
"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."
