| 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.
