earthle is a simple thing, all it does is make the google background black and the words darker grey but still readable. It is powered by google, it's exactly the same except for the colors. The goal is to cut down on energy usage, because as I'm sure you all know a black LED is actual a turned off LED, not using any power. If most google users switch to earthle, "an estimated 750 megawatt hours a year" will be saved. This helps the earth, as it cuts down on usage, blah blah blah. I encourage everyone to share this with others and to use it yourselves.
