Every Friday I’ll send you a wonderful website that my classes and my parents love. I think you’ll find they’ll be a favorite of your students as they are of mine.
Blackle.com is a search engine. It’s pretty much like Google–in fact, it’s run by Google–but you notice right away you’re not at Google.com or Yahoo or any other search engine you’ve every used. Why?
The background is black.
That itty bitty change in surfing saves energy. In fact, Blackle had saved 2,440,165.420 Watt hours as of the hour I checked.
Blackle was created by Heap Media to remind us all to take small steps in our everyday lives to save energy. “…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.
To the naysayers, Blackle responds, “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.”
