About this report

A question-led energy analysis that looks at both the power required by AI and AI’s potential effects on energy systems. The report examines data-center demand, efficiency, location, design, electricity procurement and onsite generation before considering prices, security, physical AI and wider productivity effects. It combines outlook analysis with explanations of infrastructure and market constraints. Use it to connect AI infrastructure plans with energy strategy, compare supply choices and identify where uncertainty about deployment or economic growth changes the implications for electricity demand.
