How does Xrisi Conserve Energy? Xrisi is designed to save energy by displaying mostly black pixels on the computer monitor. "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 It is known that white web pages require around 74 watts to be displayed, while black web pages use only 59 watts. As you can see, the Xrisi webpages are primarily constructed with black pixels. With this in mind, the black google requires less energy to search the web. So why not use Xrisi for your primary web search needs? The search engine was created in hopes of refreshing the idea of saving energy and acts as a reminder that each one of us can make a difference. The Xrisi search engine is powered by Google Custom Search and offers another step towards energy conservation. The Classic Google has over 200 million search queries made per day. Our ultimate goal is for everyone to switch over to Xrisi. This would save 750 Megawatt-Hours a year!
How can You Help? We encourage you to set Xrisi as your hompage. This way every time your web browser loads, you will be saving small amounts of energy. Remember that every little bit of energy saved counts in the long run! You will also be reminded to keep saving energy throughout the day. Help us spread the word about the black google page so that our concept will have a greater impact on the environment. Make sure to tell your friends and families to set Xrisi as their homepage . If you have a blog, it would be great if you could mention us shortly in a post of yours.
