Blackle
Received this email at work today and thought I'd share. Sorry if it is a repost.
It sounds like the verdict is still out on how much energy is saved by using blackle instead of google, but it just looks so damn cool we should all use it anyway.

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.

Sure it will save energy if you have a 20 year old CRT. LCD monitors or laptops, which power their backlight consistently regardless of the image the LCD in front of them is displaying you wont save diddly squat.
