IEA projects data-centre electricity near 950 TWh by 2030
The IEA central projection roughly doubles data-centre electricity from 485 TWh in 2025 to 950 TWh in 2030.
Evidence explainer
What this establishesThe projection is a forecast with stated bottlenecks reducing the likelihood of more aggressive near-term scenarios.
Why it matters: It supplies a shared numerical baseline for grid planning and AI infrastructure policy.
Limits and context: The same summary notes upside cases and supply-chain constraints that can change outcomes after 2030.
