PUE

(Power Usage Effectiveness) In a datacenter, the ratio of electrical power used by the servers in contrast to the total power delivered to the facility. Used to measure the effectiveness of cooling systems, the perfect PUE would be 1, which means that all the power coming into the room is used by the servers inside. In practice, 1.6 would be extremely efficient, because the average datacenter PUE is 2.5.

It has emerged as the most popular metric for measuring data centre efficiency, and some large companies, notably Microsoft and Google, have been publishing PUE numbers as a way to show off the efficiency of their newest facilities.
If we ignore the sticky problem of 'what' the data centre actually 'does' we are left with one metric that has found almost universal favour--Power Usage Effectiveness, or PUE.
The data center industry uses the PUE rating as the standard measurement to describe the power usage effectiveness and measure the efficiency of any given site.
