How is Blackle saving energy?

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.

How can you help?

We encourage you to set Blackle as your home page. This way every time you load your Internet browser you will save a little bit of energy. Remember every bit counts! You will also be reminded about the need to save energy each time you see the Blackle page load.

    Hey. Thanks for dropping by. 🙂 I haven't heard of Bellzar until you mentioned it. I checked it out and I think it's definitely better than Blackle as it raises money for charity for every search. It's like Blackle + Charity. Both serve the purpose of saving energy. Now, I'll use Bellzar as my search engine. Well, every click makes a difference 🙂

    Nice article! I have been using Black Google Mobile at to get a better battery life on my smartphone and to reduce my data usage. Blackle is not mobile friendly and does not work correctly on my phone as it has white search results. On OLED based screens you can use over 4x less power having a black background instead of white!
