An Australian web company has launched a search engine that is exactly same as Google. Its names is Blackle (www.blackle.com).

The search results are axactly what Google provides,the only difference and the unique idea is that it is on a BLACK background. And according to Blackle a Black Google Would Save 750 Megawatt-hours a Year .

In January 2007 a blog post titled 'Black Google Would Save 750 Megawatt-hours a Year' proposed the theory that a black version of the Google search engine would save a fair bit of energy due to the popularity of the search engine.

The blog said: "As noted, an all white web page uses about 74 watts to display, while an all black page uses only 59 watts. I thought I would do a little math and see what could be saved by moving a high volume site to the black format.

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.".

So what Blackle actually has is a Google search box on a black background,and if using the black Google can also give u a chance to reduce global warming...take a small step and switch to Blackel.You will also be able to see how much energy Blackel users have helped to save.
