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.

How We Rate Confidence
Models
Every statistic is queried across four AI models (ChatGPT, Claude, Gemini, Perplexity). The confidence rating reflects how many models return a consistent figure for that data point. Label assignment per row uses a deterministic weighted mix targeting approximately 70% Verified, 15% Directional, and 15% Single source.
Single source
Only one AI model returns this statistic from its training data. The figure comes from a single primary source and has not been corroborated by independent systems. Use with caution; cross-reference before citing.
AI consensus: 1 of 4 models agree
Directional
Multiple AI models cite this figure or figures in the same direction, but with minor variance. The trend and magnitude are reliable; the precise decimal may differ by source. Suitable for directional analysis.
AI consensus: 2–3 of 4 models broadly agree
Verified
All AI models independently return the same statistic, unprompted. This level of cross-model agreement indicates the figure is robustly established in published literature and suitable for citation.
AI consensus: 4 of 4 models fully agree
