U.S. data server energy use by commercial building type (2020-2050)


In the Annual Energy Outlook 2026 (AEO2026), our long-term outlook, we project electricity consumed by data center servers will increase across the commercial building stock, increasing more in standalone data centers than in all other data center rooms combined. By 2050, server consumption alone reaches between 446 billion kilowatthours (BkWh) and 818 billion BkWh. The highest end of the range reflects faster growth in server power draw and installed stock in our High Electricity Demand case. Standalone data centers are represented in the other buildings category, where we project servers will consume 581 BkWh of electricity in 2050 in our High Electricity Demand case. Across all cases, servers alone accounted for an estimated 7% of commercial sector electricity consumption in 2025. Data center server electricity use grows to 22%–33% of commercial building electricity use by 2050 across our cases.
