What if we could save energy using Google? That's the idea behind Blackle. Apparently, a computer exerts less energy displaying a black screen than it does a white screen. With that thought in mind, a group called Heap Media believes a black Google would conserve a significant amount of energy if multiplied by the number of searches conducted on Google each day. So if you're not quite ready to go hybrid or buy those expensive light bulb, just use blackle. It's certainly an interesting idea, despite it's name. (I would would have gone with Google Dark or something less forced feeling.) Maybe Google will decide to go green by going black and take up the cause on their own. Another example how a little goes a long way.
