In 2025, data centers evolved from passive utility customers to active energy planners, investing in on-site generation, battery storage, and flexible demand to serve AI compute and hit sustainability targets. Data centres are a vital infrastructure supporting our ever-growing use of cloud storage, social media, AI, streaming services and more. A data center typically contains multiple computer servers, data storage devices, and network equipment that can provide information technology (IT) infrastructure service for organizations to store, manage, process, and transmit large amounts of data. Energy-efficient AI, battery storage systems, and renewed interest in nuclear have reshaped how data centers generate, consume, and manage energy. A new report from the IEA assesses how the relationship between energy and artificial intelligence (AI) is evolving rapidly, drawing on the latest data and analysis and close tracking of technological and economic developments in the AI sector. Projections indicate this share could roughly double by 2030, with the pace of expansion well beyond what was anticipated only a few years ago.
