On a CRT (the old-style, cathode-ray tube monitors), far more electronsfire at the screen to display the regular white Google page than wouldbe necessary if it were black. Therefore, the idea is that ifeveryone used Google Black, the collective web community would loweroverall energy consumption worldwide.
The problem is that this only applies to CRT's and, to a far lesserextent, newer LED displays (which are still so energy efficientthat the impact is not nearly as great). LCD and plasma screensuse just as much energy to display a black page as a white page, so intoday's world where almost no one uses CRT's it's kind of pointless.
i think it works because the screen isn't producing color in the black.so if its not making color its not using light so its not using as muchelectricity saving power

No idea, no interest, but I'd suggest googling it.
