I came accross this website the other day, and was intrigued at the concept behind the site.
The concept, quoted from www.blackle.com states:
"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 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."
As environmentally conscious attitudes pervade society more frequently, environmental endeavours, however small, are popping up all over the place.
