Maybe this should have gone under computers. Oh well.


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".

They also said one of their goals was to keep people energy minded, which this does if it's set as your homepage.

"Oh hey, Blackle <random train of thought> I should conserve energy."

"Should, but I'm rather fond of the 800-watt PC of Doom I'm using to view the page..."

Really the saved energy only happens when the black screen replaces the white screen on tens of millions of computer screens during tens of millions of searches.

So just switching to this site isn't going to do much.

Well yeah, but if lots of people do... I mean, that's the point. If lots of people use it there's lots of energy saving.

If you really want to save energy, though, turn off your monitor when you're not using it. We started doing it at my high school and it sheared like 20% off our electricity bill.

I'm pretty much the only one of my roommates who ever turns off lights.

It's weird, because I grew up in a house where every room gets lots of natural sunlight. Now this apartment I live in, only a few rooms get any. So like the bathroom or the hall you have to have the light on if you're going to use it.
