AI Factories Surge: AI-Focused Data Centers Consumed 155 TWh in 2025
The IEA confirmed that AI-focused data centers consumed 155 TWh of electricity globally in 2025 — a 50% increase in a single year. Total global data center electricity reached 485 TWh, up 17%, with AI carrying most of the growth. AI factories — facilities purpose-built for training and inference at scale — more than tripled in capacity over 18 months. The IEA projects AI-focused data center demand could triple again by 2030, reaching roughly 465 TWh, accounting for nearly half of all data center power globally.
Findings
- AI-focused data centers consumed 155 TWh globally in 2025, up 50% year-over-year — confirmed by IEA actuals, not projections
- Total global data center electricity hit 485 TWh in 2025, a 17% increase, with AI infrastructure the primary growth driver
- AI factories tripled capacity in 18 months; IEA base case projects AI-focused data center demand to triple again by 2030
- A single AI-optimized hyperscale facility now uses as much electricity as 100,000 homes annually, with next-gen mega-facilities 20x larger
- US data centers accounted for roughly half of all new American electricity demand in early 2026, raising average residential bills in affected grid regions
