Internet dominator Google have come up with a 5 step approach to building sustainable and eco-friendly data centers.

Google’s mission is to organize the world’s information and make it universally accessible and useful. Hundreds of millions of users access our services through the web, and supporting this traffic requires lots of computers. We strive to offer great internet services while taking our energy use very seriously. That’s why, almost a decade ago, we started our efforts to make our computing infrastructure as sustainable as possible. Today we are operating what we believe to be the world’s most efficient data centers.

This is quite blatantly a mission statement rather than a report. There are no specifics or detailed facts or figures. There is a lot of uses of graphs like this one, that have no scales on them, which makes them rather meaningless.

I am quite happy to accept that Google have become more efficient, but exactly how much?
