Blackle - Power saving Google Custom search version

Do you know which is the google's power saving version. It's the BLACKLE.

Blackle is a website powered by Google Custom Search and created by Heap Media. This is what Blackle says about itself.
How does it differs from regular Google? Just the color and logo. The basic idea is that computer monitor uses less power to display dark colors. 

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.

In 2014 the majority of monitor sales are LED backlit LCD's which do not light up the parts of the screen that are black. Some older CCFL LCD monitors worked by wastefully backlighting the entire screen. Since 2005 manufacturers have moved away from CCFL's.

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.

Blackle was created by Heap Media and is powered by Google Custom Search.
