Power Usage Effectiveness Last modified: Thursday, May 14, 2009
In Green IT, Power Usage Effectiveness (PUE) is a calculation used to determine energy efficiency measurements. PUE is calculated by measuring the ratio of total energy consumption—the combination of servers plus the cooling to "useful" energy consumption (just servers). PUE is a green computing tool being promoted by The Green Grid as a way to measure the power delivered to IT equipment in its ratio with its total power consumption in the data center. The Green Grid measures the following: PUE = Total Facility Power / IT Equipment Power (where Total Facility Power is the power measured at the utility meter. The IT Equipment Power is the actual load associated with all of the IT equipment including computing, storage and networking equipment).

The Green Grid The members of The Green Grid have taken up the challenge of developing standards to measure data center efficiency, which includes both the facility and the IT equipment inside of it. The Green Grid Data Center Power Efficiency The Green Grid is an association of IT professionals seeking to dramatically raise the energy efficiency of data centers through a series of short-term and long-term proposals.
