Global data center average annual Power Usage Effectiveness (PUE) 2007-2024

Responding to a 2024 survey, data center owners and operators reported an average annual power usage effectiveness (PUE) ratio of 1.56 at their largest data center. PUE is calculated by dividing the total power supplied to a facility by the power used to run IT equipment within the facility. A lower figure therefore indicates greater efficiency, as a smaller share of total power is being used to run secondary functions such as cooling.

在2024年的调查中，数据中心的所有者和运营商报告称，他们最大的数据中心平均年电力使用效率（PUE）比为1.56。PUE是通过将设施供应的总功率除以设施内运行IT设备的功率来计算的。因此，较低的数值意味着更高的效率，因为更少的总功率被用于运行次要功能，如冷却。
