In January the blog Ecolron published a post about energy saving methods high volume websites could implement. Considering that a white web page uses about 74 watts to display, while an all black page uses only 59 watts, Ecolron calculated how much energy a high volume site like Google (with 200 million + hits a day) would save if it simply had a black background. Here is what he found:

“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.” –Ecolron

Google, in recognition of this idea, launched Blackle.

Blackle is the same powerful Google search engine we all love with an all black background. Every little bit counts, so even if the energy savings are minuscule, they will add up every time you open up Blackle instead of the all white Google. So go ahead and set Blackle as your home page!!! It is as essential as your little black dress collection!

    I prefer using http://www.Darkoogle.com as their text are green which reduce eye strain. So instead of saving energy from our monitor, it also save our user’s eye energy.
