PUE ratings on the move?

New figures published on the DatacenterDynamics site suggest that PUE ratings are on the move. And the PUE is going down. The modal PUE rating has moved year-on-year below 2.00 to lie within the 1.85-1.90 range by 2009 as shown in the diagram below of DatacenterDynamics. But you also can see we are still wasting a lot of energy in the data centers. This are rough figures, we should be aware that measurement of PUE still is not standardized.
