Please note: PUE: A Comprehensive Examination of the Metric supersedes all prior white papers and consolidates all of the new and previously published content that The Green Grid has developed related to PUE.
The Green Grid explains the use of the Power Usage Effectiveness (PUE) metric, along with its reciprocal the Data Center Efficiency (DCE) metric. These metrics are designed to allow a data center operator to relatively quickly estimate the energy efficiency of their data center, as well as to quantify how the data center stacks up against its peers.
