According to some, an all white web page uses about 74 watts to display, while an all black page uses only 59 watts.
Google, which has a white background and gets about 200 million queries a day could reduce global energy use by 750 Megawatt-hours a year by simply changing the color of its homepage to black.

BTW, we’re turning off the lights tonight and going out to a fade to black concert that’s being powered by renewable energy sources.
