Blackle !!

Vinay sent me a really interesting email which pointed to this site.

Blackle is the black version of Google. And since the amount to usage of Google is bound to increase it makes sense using blackle.Another fact is that it doesnt save much energy from LCD displays which are very popular today but does save a chunk from CRT displays


Blackle was created by Heap Media to remind us all of the need to take small steps in our everyday lives to save energy. Blackle searches are powered by Google Custom Search.

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.

  1. I use Black Google Mobile at to get a longer battery life on my phone and to reduce my data usage. I use it in Firefox on my computer too! On the newer OLED based screens you can use 4x less power having a black background instead of white! People who say black cannot save energy are out of date and do not account for all the OLED based devices that are in use now and growing fast in popularity. There is more information on this at Blackle is not mobile friendly at all and delivers search results with a white background on my phone!
