See where data centers are across the US on our interactive map (www.businessinsider.com)

Business Insider released an interactive map and underlying dataset that locates every data center in the U.S. that was built or approved through the end of 2024 — 1,240 facilities, the most comprehensive tally to date — with a searchable table (by county, state, ZIP, or corporate parent) and sortable low/high estimates of electricity use. Users can click any map marker or table row to see facility-level details, helping communities and researchers visualize where the rapid construction tied to the AI boom is concentrated and how much power those sites might consume. To assemble the database, journalists homed in on a consistent regulatory trail: backup diesel generators. Because large generators generally require state air permits, BI requested permit records from all 50 states and DC, used industry codes to locate likely data-center permits, linked hundreds of shell companies to their corporate parents, and even sued some municipalities to obtain records. Electricity-use ranges are derived from Business Insider’s published methodology applied to each facility or cluster. The result is a public, auditable resource that clarifies the scale, siting, and energy implications of the data-center buildout — information with direct relevance for grid planners, regulators, environmental assessment, and community debates over the costs and benefits of AI-driven infrastructure growth.
