| '''Power usage effectiveness''' ('''PUE''') is a measure of 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).

| PUE was developed by a consortium called [[The Green Grid]]. PUE is the [[multiplicative inverse|inverse]] of [[data center infrastructure efficiency]] (DCIE). 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.
