Answer» What is Power Usage Effectiveness mean? 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 to cooling and other overhead that supports the equipment). PUE is the ratio of total amount of energy used by a computer data center facility to the energy delivered to computing equipment. PUE is the inverse of data center infrastructure efficiency (DCIE). PUE was originally developed by a consortium called The Green Grid. PUE was published in 2016 as a global standard under ISO/IEC 30134-2:2016 An ideal PUE is 1.0. Anything that isn't considered a computing device in a data center (i.e. lighting, cooling, etc.) falls into the category of facility energy consumption. P U E = Total Facility Energy IT Equipment Energy = 1 + Non IT Facility Energy IT Equipment Energy {\displaystyle \mathrm {PUE} ={{\mbox{Total Facility Energy}} \over {\mbox{IT Equipment Energy}}}=1+{{\mbox{Non IT Facility Energy}} \over {\mbox{IT Equipment Energy}}}} reference
