Working Up a Black Search: Google's Energy-Friendly Homepage
UPDATE: This is looking pretty hoaxey... hence the "fishy" flag...
This is one for the never-would-have-thought-of-this department, but here it is: since activating the pixels in a computer's display uses electricity, and Google's home page is mostly white, a great deal of electricity is getting used just for searching. When an environmentalist blogger blogged this, Google found out and launched a less power-hungry home page... called Blackle. Think of it as the Prius to Google's white-screened Hummer.
Google, which has a white background and gets about “200 million queries a day” could reduce global energy use by 750 Megawatt-hours a year by simply changing the color of its homepage to black. (For more detailed calculations and assumptions check out the original post here.)
In response to this post a black version of Google emerged called Blackle.com. According to Blackle’s homepage at publication time, 4,408.917 Watt hours have been saved by. The site encourages users to “make a difference today [by] … Blackling "energy saving tips" or visit[ing] treehugger.com a great blog dedicated to environmental awareness.” Nice ideas. But how does the search measure up? Very well indeed. Give it a whirl yourself and start saving energy one search at a time.
--> At the moment, Blackle seems to be down! We keep getting 403 errors, but I promise that this really exists...
