How is Blackle saving energy?
Blackle saves energy because the screen is predominantly black. “Image
displayed is primarily a function of the user’s color settings and desktop graphics, as well as the color and size of open application windows; a given monitor requires more power to display a white (or light) screen than a black (or dark) screen.” Roberson et al, 2002
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. Since then there has been skepticism about the significance of the energy savings that can be achieved and the cost in terms of readability of black web pages.
We believe that there is value in the concept because even if the energy savings are small, they all add up. Secondly we feel that seeing Blackle every time we load our web browser reminds us that we need to keep taking small steps to save energy.
Just A Scrap Wishes Blackle all sucess. To Make blackle a success we request all users to set their homepages to Blackle.com

A black screen just saves a little bit engery with old fashioned CRT-Displays. Modern LCD-TFT Technology works different. The Backlight is always on, to display “black” the screen blocks the light but doesnt save any power. The so promised engery savings up to 750 Megawatt a year are in no way correct.

yea dennis i read that laters. With LCD i heard black takes more energy and it’s actually wasting more energy there. I heard google is just trying to Popularise Blackle because each and every search done there pays them. Dont know how far this is true
