Decoding Data Center Efficiency Metrics: A Guide to Energy, missions, and Sustainability

Published 1 month ago

We’ve prepared a comprehensive guide to measuring data center energy performance -- from PUE to Scope 3 emissions and beyond.

In the late 19th century, British Physicist Lord Kelvin said: “If you cannot measure it, you cannot improve it.” A century later, Peter Drucker paraphrased it by saying: “If you can’t measure it, you can’t change it.”
Metrics, then, are a vital part of management. They eliminate any opinion about whether conditions are improving or worsening. But metrics are an imperfect mechanism as they can sometimes fail to represent the real world and may not reflect the thing you seek to address, change, or monitor.
Over the years, many data center metrics have been proposed. Various standardization efforts have emerged to bring about some consensus on definitions and methods to be used to count the proposed metrics. No metric is perfect, though some have proven to be more useful than others. 
According to a study by EPRI, data centers could consume up to 9% of US electricity generation by 2030 – more than double the amount currently used. With so much more electricity destined to be used in data centers during a period when decarbonization and sustainability are being prioritized, the precise measurement of data center energy usage and emissions is now of critical importance.
This guide covers:

  • current metrics, their meaning, and how to count them or where to find an explanation of how to implement them.
  • data about emerging metrics (including those concerning the subject of sustainability)
  • The ability to cope better with artificial intelligence (AI) applications within the data center
