A new site called “Blackle.com” launched recently – the overall premise is that, by being black, it saves a few Watts of energy – over time, with lots of people using it, you could save a hell of a lot vs. Google.com.

It’s powered by Google, but it doesn’t seem to be a Google site (although that’s always hard to tell!).

Now – in an age where we go to lengths to carbon offset, despite the idea being rather ridden with shysters who’ll take your money and do nothing with it, doesn’t this seem a simple little idea. But, what if “Ask.com” had done it – maybe they’d have actually gained some share on that?

They’ve written a good spiel on it, which I’ll paste here…

“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.

Help us spread the word about Blackle by telling your friends and family to set it as their home page. If you have a blog then give us a mention. Or put the following text in your email signature: “Blackle.com – Saving energy one search at a time”.
