Blackle is the NEW Google

Tuesday, July 31, 2007

In an article written by Mark Ontkush, he points out that "an all white web page uses about 74 watts to display, while an all black page uses only 59 watts." According to him,

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. 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 $75,000, a goodly amount of energy and dollars for changing a few color codes.

In response to this, Google created a black version of its search engine. The Blackle has the exact same functions as the white version, but with lower energy consumption. Check it out at www.blackle.com. Here's a snapshot of the black version:

    olrayt! My blog is predominantly black. I'm saving energy. Besides looking at an predominantly white screen is like looking at a flourescent lamp all day. :)

    Question: How many eureka! moments do you have everyday?

    Haha usually I get about 10 eureka moments but not all of them is about technology and computers. Some days, when I'm too busy with work, I don't have any eureka moment at all :(

    hi, actually you're only saving energy if your readers have CRT monitors. If most of them use LCD screens it's making them use MORE energy...
