“What we've seen is that in the last 1520 years, while the amount of compute and data storage has increased a lot, in some cases more than 10 X, depending on the geography and time frame, the energy consumption has actually barely budged. It has barely gone up, and that's mostly thanks to the increasing Efficiency, the energy efficiency of data centers”

The claim, plainly

Over the past 15 to 20 years, while compute and data storage grew by more than 10x in some regions, data center energy consumption barely increased due to efficiency gains.

a quote alone can be ambiguous, so this restates it with the references and context of the conversation around it resolved. AI-written; the tape below the player is the source.

Assessment

The claim accurately reflects the findings of leading peer-reviewed studies and international energy tracking reports covering the ~15 to 20 year period preceding the 2024 claim. Specifically, Masanet et al. (Science, 2020) demonstrated that between 2010 and 2018, global data center storage capacity grew by 25-fold to 26-fold and compute instances grew by 550%, while global data center electricity consumption grew by only ~6% (from 194 TWh to 205 TWh) due to major efficiency gains (server virtualization, processor efficiency, and hyperscale PUE improvements). Similarly, the International Energy Agency (IEA) reported in 2021 that between 2010 and 2020, data center workloads expanded nearly 10-fold while total electricity demand remained roughly flat at around 1% of global electricity consumption. Furthermore, the 2016 LBNL U.S. Data Center Energy Usage Report confirmed that U.S. data center electricity consumption grew by only ~4% between 2010 and 2014 despite a >20x increase in storage capacity.

Masanet et al. (Science, February 2020) showed global data center electricity use rose only ~6% (194 TWh to 205 TWh) between 2010 and 2018 despite a 25x-26x surge in storage capacity and 550% growth in compute instances.
The International Energy Agency (IEA) confirmed that between 2010 and 2020, data center workloads increased by ~9.4x while global data center electricity demand remained roughly flat (~200-220 TWh).
LBNL's 2016 study documented that U.S. data center electricity consumption flattened to ~4% growth between 2010 and 2014 while storage grew by over 20x from 2007 to 2016.

Palazzi: Energy companies are shifting from hard-coded models to production AI

“I think that's a big shift that has taken place, that in production by companies that are serving real customers, AI is used much more commonly. So a shift from hard-coded, pre-set-up, fully visible models into more machine learning and AI.”
