'''Power usage effectiveness''' ('''PUE''') |
'''Power usage effectiveness''' ('''PUE''') is a ratio that describes how efficiently a computer [[data center]] uses energy; specifically, how much energy is used by the computing equipment (in contrast [[computer cooling|to cooling]] and other overhead that supports the equipment). |

PUE is the ratio of the total amount of energy used by a computer [[data center]] facility<ref>{{cite web|url=http://searchdatacenter.techtarget.com/sDefinition/0,,sid80_gci1307933,00.html|title=What is power usage effectiveness (PUE)? - Definition from WhatIs.com|publisher=}}</ref><ref>[[Digital Realty]] - [http://www.digitalrealtytrust.com/pue-efficiency.aspx PUE Data Center Efficiency Metric]</ref><ref>{{cite web|url=http://www.esmagazine.com/Articles/Feature_Article/BNP_GUID_9-5-2006_A_10000000000000160061|title=Optimizing Power Usage Effectiveness In Data Centers|website=www.esmagazine.com}}</ref><ref>{{cite web|url=http://www.thegreengrid.org/sitecore/content/Global/Content/white-papers/The-Green-Grid-Data-Center-Power-Efficiency-Metrics-PUE-and-DCiE.aspx|title=The Green Grid - The Green Grid Data Center Power Efficiency Metrics: PUE and DCiE|publisher=}}</ref><ref>[[Google]] - Efficient Computing - [https://www.google.com/about/datacenters/efficiency/internal/index.html#measuring-efficiency Data Centers - Efficiency: How we do it?]</ref><ref>[[Dell]] - [http://www.dell.com/downloads/global/power/ps1q08-20080185-Rad.pdf Best Practices for Increasing Data Center Energy Efficiency]</ref><ref>[[Cisco Systems]] - [http://www.cisco.com/en/US/prod/switches/ps5718/ps10195/white_paper_c11-514539.html Cisco Energywise]</ref><ref>[[Google]] Data Center Optimization - [http://static.googleusercontent.com/media/www.google.com/en/us/about/datacenters/efficiency/internal/assets/machine-learning-applicationsfor-datacenter-optimization-finalv2.pdf]</ref>{{Excessive citations inline|date=February 2024}} to the [[Electric energy|energy]] delivered to computing equipment.
