Blacksurfing is surfing the Web using an inverted palette, with white text on a black body. Shifting a high traffic website, like Google, from a white background to a black background can save substantial energy. An all-white web page uses about 74 watt s to display on a CRT monitor as compared to an all-black page that uses only 59 watts. Blackle, an energy-saving search engine that uses Google's custom search, is an example of this practice put into use.
