Berkeley Lab Puts a Hard Number on Data Center Power Demand
How it leans Measurement only · Government lab (DOE / Berkeley Lab)
What's documented Federally funded national lab measurement, peer-reviewed methodology, no industry sponsor and no policy ask.
The 2024 United States Data Center Energy Usage Report, prepared by Berkeley Lab for the Department of Energy, is the reference dataset behind the entire debate. It measures, rather than projects, what data centers actually consumed, then bounds the near-term growth. Use it to sanity-check any cost claim: the load is real and large, but it is a single-digit share of national demand today.
- Data centers consumed about 176 TWh in 2023, roughly 4.4% of total U.S. electricity.
- Consumption is projected to reach 325 to 580 TWh by 2028, about 6.7% to 12% of national demand.
- Data center load roughly tripled over the prior decade and is projected to double or triple again by 2028.
