Water Usage Effectiveness (WUE) is a sustainability metric defined as the annual water consumed by a data center, primarily for cooling, divided by the IT equipment energy, expressed in litres per kilowatt-hour. Established by The Green Grid, it complements PUE, with lower values indicating more water-efficient cooling.
