Feb 26, 2009-- When thirteen-year-old Andrew Davey read a blog by a leading expert in green computing, explaining how changing from a white background computer screen to a black one could save energy, he decided to put the theory to the test. He is now the proud owner of an environmentally-friendly search engine called Ecosmartsearch.com -- a search engine with the motto "We are saving energy, now it's your turn". Andrew's search engine uses a black background which saves energy because the computer monitor uses 59 watts to produce the image on the screen, whereas a white or light screen uses 74 watts to display the image. This means that every time ecosmartsearch.com is used, it saves 15 watts. As it is Google-powered, the search results are exactly the same but use less energy. (4285 reads)
