Google DCs are "the most efficient in the world" according to Urs Hölzle and Google's latest study.

Google is not green. Beeing ecological is just a way to save a lot of money. If there was another better way to save money, they would use it instead and they would drop their green cover.

They are not green? Of course they are. And of course they do it because it saves them money. And of course they do it because it makes us love them. Is that wrong? They're a corporation. They're a hell of a lot better than any others that i know of. A corporation is not a person and cannot have a true since of "doing the right thing" but at least they've been able to make doing the right thing good for them. Others still seem to think they need to screw over customers in every possible way to make money

The study seems to compare relative electricity use – I'm curious about such a comparison using absolute numbers :)

TOMHTML, I'm not privvy on the big decisions, but I can say for sure that the primary objective when deciding to do something green is not to save money. Luckily sometimes being green and saving money come together (eg. putting up solar panels, saving energy, etc.).
