Power Usage Effectiveness (PUE)

Power Usage Effectiveness (PUE) is the standard measure of how efficiently a data center uses energy. It is a ratio comparing the power used by a data center's IT equipment to the total power consumed, including overhead services like cooling, lighting, and power conversion. PUE provides insights into the energy efficiency of a data center, with a lower ratio indicating more efficient use of power. This metric is key for evaluating and improving the environmental impact of data center operations.
