Background
Lawrence Berkeley National Laboratory (LBNL) is the US Department of Energy research laboratory at the University of California, Berkeley. Its Data Center Technologies team publishes the authoritative tracking reports on US data centre electricity consumption, used by the IEA, EPA, and Congress as the primary evidence base for energy policy affecting the sector. LBNL's 2024 update found US data centres consumed approximately 200 TWh of electricity in 2023, roughly 4% of national consumption, with AI workloads identified as the fastest-growing sub-category.
The laboratory's reports are directly cited in the IEA's April 2026 global data centre electricity analysis, which restated the 17% global demand growth figure and projected a further 75% rise in hyperscaler capex in 2026. LBNL's methodology — combining facility surveys, utility data, and hardware shipment tracking — is considered the gold standard for consumption estimation in the absence of mandatory disclosure.
LBNL is managed by the University of California for the US Department of Energy. Its researchers have testified before Congress on data centre energy policy and contributed to the EPA's ENERGY STAR programme for data centre equipment.
