Google in Black
May be we can start using an alternate homepage of google than the regular google.com
the new page has black background. Reason: white colour display consumes more energy than black colour background.

Black Google Saves Energy
by Celine Ruben-Salama, New York, NY on 05. 7.07
A few months ago, TreeHugger Mark Ontkush wrote a post on his blog EcoIron titled Black Google Would Save 750 Megawatt-hours a Year. The post lays out the following train of thought. "An all white web page uses about 74 watts to display, while an all black page uses only 59 watts." 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.
