Blackle.com – A Google Custom Search Engine

I got one of those “viral” emails today, related to the ecoIron post on a Black Google Homepage a while back:

The new Google

For those worried with energy consumption and all its downsides… When your screen is white, being it an empty word page, or the Google page, your computer consumes 74 watts, and when its black it consumes only 59 watts. So a man named Mark Ontkush wrote an article about the energy saving that would be achieved if Google had a black screen, taking in account the huge number of page views, according to his calculations, 750 mega watts/hour per year would be saved.

In a response to this article Google created a black version of its search engine, called Blackle, with the exact same functions as the white version, but with a lower energy consumption, check it out.

I must hand it to the guy that put it together – it’s very clever, and he is using the Google Custom Search Engine, which means that as this viral campaign spreads, he drives more search volume to Google, and also makes money out of it! Smart, very smart!

From the Blackle About Page:

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. 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”.

There are a lot of great web sites about saving energy and being more environmentally friendly. They are full of great tips covering the little things that we can all do to make a difference today.

Again – very smart, but just another Internet fad!
