Blackle, which is basically Google Search in a different looking window, 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.

Whatever you want to make of it, I think it is still worth a mention, as they say "God is in the details." Thanks to Christina for pointing it out!

Wow! Black is my favorite non-color (aside from white). But the features that the white Google has are not there, like news and image features. But overall, it is very easy on the eyes and less of a headache, too. I'm gonna stick with this one.

I prefer using www.Darkoogle.com as their text are green which reduce eye strain. So instead of saving energy from our monitor, it also save our user's eye energy.

There are around 25 different versions of “black google” online. The best one I’ve found is www.cleanblack.com. Cleanblack is the only version that allows you to change the text colors of the google search results. Try it yourself by going to www.cleanblack.com/theme/
