This black webpage sounds nice :

<< 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. >>

Wow, it's a nice idea! It remembers me when I wanted to change the world's energy source to tons of lemons (it's a bit expensive though)

Presumably energy savings would only apply to CRTs, not to LCDs which effectively have a fixed fluorescent light bulb behind the liquid crystal.

If you use LCD monitor, you'll end up wasting more energy by using Blackle. Not to mention that you'll stress your eyes and suffer from eye problems.

Blackle will save energy only for CRT displays (which . On an LCD monitor, it will waste more energy than normal Google. Almost all the modern monitors are LCD monitors, as CRT monitors are obsolete.

The so-called "Save Energy" seems to be a ploy by Blackle to attract more traffic to their site, as they earn money for every search made on their site.
