Data Centers Use Less Energy Than You Think

If the world is using more and more data, then it must be using more and more energy, right? Not so, says a comprehensive new analysis.

If the world is using more and more data, then it must be using more and more energy, right? Not so, says a comprehensive new analysis.

Researchers at Northwestern University, Lawrence Berkeley National Laboratory and Koomey Analytics have developed the most detailed model to date of global data center energy use. With this model, the researchers found that, although demand for data has increased rapidly, massive efficiency gains by data centers have kept energy use roughly flat over the past decade.
 
This detailed, comprehensive model provides a more nuanced view of data center energy use and its drivers, enabling the researchers to make strategic policy recommendations for better managing this energy use in the future.
 
“While the historical efficiency progress made by data centers is remarkable, our findings do not mean that the IT industry and policymakers can rest on their laurels,” said Eric Masanet, who led the study. “We think there is enough remaining efficiency potential to last several more years. But ever-growing demand for data means that everyone — including policy makers, data center operators, equipment manufacturers and data consumers — must intensify efforts to avoid a possible sharp rise in energy use later this decade.”
