you are right. there is no effect on LCD monitors. As far as I know though, its not actually done by google, so not really their claim.
im all for positive changes, but for sure, the amount of energy used on a black vs. white screen, for the short time people use a google page, ONLY on CRT’s can’t add up to much, even with the millions of computers in the world. wouldnt be surprised if the sum total per day of savings equals one person turning off one incandescant lightbulb in china.
gets the hype though and blog hits, hopping on the bandwagon.
