Data centers now attract more investment than than finding new oil supplies

A recent report from the International Energy Agency (IEA) highlights a significant shift in global investment trends, revealing that spending on data centers is set to reach $580 billion this year. This figure surpasses the $540 billion allocated for new oil supplies, marking a pivotal moment in the evolution of the digital economy. The IEA's findings indicate that the electricity demand from AI-driven data centers is poised to increase fivefold by the end of the decade, effectively doubling the current energy consumption of all data centers worldwide. While traditional data centers will also see an uptick in energy use, the growth rate won't be as pronounced. A substantial portion of this demand growth is projected to occur in the United States, with Europe and China also contributing significantly. The agency notes that many new data centers are emerging in large metropolitan areas with populations exceeding one million. Impressively, half of these upcoming facilities will boast capacities of at least 200 megawatts, and many are strategically located near existing data centers. However, the rapid expansion of data centers, particularly in clustered urban settings, is not without its challenges. The IEA warns of increasing grid congestion and lengthy connection queues in numerous regions. For instance, in northern Virginia, waiting times for grid connections can stretch up to a decade. Meanwhile, Dublin has halted new interconnection requests until 2028 due to similar concerns. The supply chain for grid infrastructure is also under strain, with shortages in cables, critical minerals, gas turbines, and transformers hindering necessary upgrades. Companies like Amperesand and Heron Power are pioneering solid-state transformers, which promise to modernize the grid and enhance its ability to integrate renewable energy sources. However, these advancements are still at least one to two years away from deployment, with production ramp-up expected to take additional time. Looking ahead, the IEA anticipates that renewable energy sources will account for the majority of power supplied to new data centers by 2035, irrespective of whether nations adhere to current policies or adopt more aggressive emissions reduction strategies. Notably, solar energy has seen a dramatic decrease in costs and is becoming increasingly favored by developers. Over the next decade, around 400 terawatt-hours of electricity for data centers is expected to be generated from renewables, compared to approximately 220 terawatt-hours from natural gas. If small modular nuclear reactors fulfill their potential, they could contribute an additional 190 terawatt-hours to this sector.
