Global data center power demand is estimated to reach 500 TWh in 2023 and could double to 1,000 TWh by 2026, even as efficiency keeps improving. While average PUE has fallen from 1.8 in 2010 to 1.5 in 2022, cooling still accounts for about 40% of data center energy use and AI workloads are pushing new power and thermal challenges. This post pulls together the key PUE, utilization, and electricity figures behind that tension between smarter infrastructure and rising load.
Key Takeaways

- US data centers achieved average PUE of 1.58 in 2022
- Hyperscale operators report PUE below 1.1 for new facilities in 2023
- Global data centers consumed between 196-239 TWh of electricity in 2022, equivalent to 1-1.3% of global final electricity demand
- In 2022, data centers and data transmission networks together accounted for 1.5% to 2% of global electricity demand
- US data centers consumed 200 TWh in 2022, up from 58 TWh in 2014
