Mapping PUE trends by data center region, age and size

Uptime Institute has conducted its Global Data Center Survey annually since 2007, gathering insights from owners and operators to better understand the evolving state of the industry. One key question asks operators to provide the operational PUE for their largest data center, providing a barometer of energy efficiency and cooling system performance. While the global average PUE has remained relatively stable since 2018 (see Figure 1), this broad view masks substantial variation at the regional and site level. In this report, results are categorized by region, facility age and total provisioned IT capacity in megawatts.
