Come to the dark side...er, what? Nevermind. Anyway, this is such a good idea! Darkoogle is a more energy efficient search site that utilizes a dark background to save more energy compared to lighter colors. Even though now cheaper monitors have less impact on energy use,
"Our web technology (that relies on AJAX) eliminates the need to reload the whole page when you submit search requests. It reduces bandwidth, server load, and creates a chain of more efficient computing connecting all the way through - starting with your home or work computer and ending in the datacenter of the hosting company. Even if the energy savings are small, they all add up."
While the dark monitor is hard on my eyes (and doesn't have more search options), the idea is intriguing. It's relatively simple, but the energy savings could really stack up in the long run. What do you think of Darkoogle and other energy efficient sites?
