A recent estimate by Morgan Stanley projects that global spending on data centers designed to support artificial intelligence (AI) will reach approximately $3 trillion (£2.2 trillion) by 2029. This amount is expected to be evenly split between construction and hardware costs. For context, this expenditure mirrors the total economic output of France in 2024.
In the UK, around 100 new data centers are anticipated to be built in the coming years to satisfy the growing demand for AI processing. Notably, Microsoft has announced a $30 billion (£22 billion) investment in the UK’s AI sector, contributing to this expansion.
AI data centers differ from traditional data centers, primarily due to their high density and energy requirements. The term “hyperscale” reflects the growing size of these facilities, which typically need tens to hundreds of megawatts of power. Specifically, AI applications often rely on cutting-edge chips from Nvidia that cost approximately $4 million each and must operate in close proximity to minimize processing delays.
Despite their efficiency, AI data centers have significant energy demands, producing power spikes comparable to thousands of homes turning on electric kettles simultaneously. This irregular energy demand poses challenges for local electrical grids. Daniel Bizo from The Uptime Institute notes that the energy consumption of AI workloads is notably more variable than that of traditional data centers.
Firms are exploring various strategies to manage energy consumption, including using gas turbines off the grid. Companies like Microsoft and Google are investing in renewable energy projects, including nuclear power, to meet rising energy needs sustainably.
However, there are environmental and legislative concerns associated with data centers, including significant water usage for cooling. Potential regulations are being discussed, particularly in locations like Virginia and northern Lincolnshire, where new data center proposals have faced scrutiny over water resource implications. Given these challenges and expenses, questions arise about the sustainability of current investment trends in AI data centers.
