How much energy does fr.blackle.com save?

It's supposed to save tons of energy... how?
Ed:

It won't save much. On a CRT, the electron gun was turned off to display black. But most computers use LCD displays with a backlight. The backlight is always on no matter what color is being displayed. Since most sites use dark text on a light background, and since re-orienting the liquid crystal pixes takes energy, this web site probably uses more energy than the regular google for most users.

Meri:

It goes on the theory that a black screen with white letters uses (minutely) less energy than the opposite. SInce Google is the predominant search engine, Blackle is a customized Google search that uses a black background, saving each computer a tiny little bit of energy consumption for each search performed using it instead of the regular Google.

Meri:

As Ed points out, the savings are realized on CRT and non-backlit LCD displays...in actuality backlit LCD displays consume slightly more energy to display black.
