Greenpeace Brazil launched a new campaign called ”Black Pixel Project”, created by Almap BBDO. In this website users can install a program that opens a small black pixel over all the windows on their monitors. This can be moved around but size stays the same. You can view real time how many people are saving energy with this feature. The purpose is to show that with each pixel black installed, a few watts are saved. The program can be used on tube monitors or plasma. You can check out the website here.

I don’t think the Maths was done by an Electronic Engineer. This doesn’t apply to LCD’s that use a constant backlight and filter out/block colour.
Even with CRT’s the “divide number of pixels/per monitor wattage and thats what you save per pixel” is a flawed principle too.
It might actually be effective on plasmas or OLED displays, however these are not commonly used for computing functions (apart from OLED mobile devices).
In my opinion a complete waste of an ad campaign, it might make people think they are helping but thats about it.
Nice job BBDO!

Here’s a fun way to think of it:
There are 86,400 seconds in a day. With the Black Pixel Project, if you turn off one pixel for a whole day you are effectively “saving” 86,400 pixel seconds.
Now take your 1024×768 monitor which has 786,432 active pixels. If you turn it off for one second, you have just saved 786,432 pixel seconds.
Over nine times more than a whole day of the Black Pixel Project.
So in summary, it would take you over nine days with the Black Pixel Project to save the same amount of pixel seconds you saved by turning off your measly 1024×768 monitor for a single second.
Awesomeness!! Best thing since the Ecofont, which also had a nice site and was totally silly and ineffectual. Sign me up!
