Google is the second Brain to many of us. We use it frequently. It uses white screen which consumes higher power."If Google had a black screen, taking in account the huge number of page views, according to calculations, 750 mega watts/hour per year would be saved?!!!!!In response Google created a black version of its search engine, called Blackle, with the exact same functions as the white version, but obviously with lower energy consumption:Help spread the word? Please use " www.blackle.com".....
