"Ecobuscador is a Google search engine technology that helps combat climate change.

Ecobuscador saves energy because the colors used are entirely of dark shades. In a monitor, most energy is used to display the colors lighter. Using dark reduces energy use and emits less CO2 into the atmosphere. In January 2007 published a study showing that only changing the wallpaper to black Google would save 750 megawatt-hours per year. "

So the creators describe Ecobuscador your search. Ecobuscador is an environmentally conscious search engine. Offers a directory of sites on the environment. Furthermore, it can be a search engine in the navigation bar both Firefox and Internet Explorer 7 (and possibly Opera, but I have not tested)
