How Much Power Do Data Centers Use?

Global data center power demand is rapidly escalating, primarily driven by AI, with the U.S. leading at 8.9% of its total power consumption, projected to reach 12% by 2028. This surge, exemplified by Virginia's 26% reliance and significant shares in the UK (5.1%) and EU (4.8%), is attracting billions in investment for new facilities and energy sources. The accelerating consumption by AI is notably boosting demand for nuclear power, signaling a significant and sustained shift in energy infrastructure requirements and investment opportunities.

Analysis

Data center power demand is undergoing a structural, rapid acceleration driven primarily by global investment in Artificial Intelligence. The U.S. is the clear global leader, with data centers currently consuming 8.9% of the nation's total power and a capacity of 53.7 gigawatts, a figure projected by the IEA to rise to 12% of total electricity demand by 2028. This trend is highly concentrated, as seen in Virginia where data centers account for 26% of the state's power consumption and its leading utility expects to connect 15 new facilities this year alone. While the U.S. leads, the trend is global, with significant power share also seen in the UK (5.1%) and the EU (4.8%), fueled by national 'AI sovereignty' efforts and substantial foreign investment. A critical second-order effect of this build-out is a surge in demand for reliable, high-capacity energy, which is driving the fastest expansion in nuclear power demand in decades as 'big tech' firms funnel capital into both the facilities and their underlying energy sources.

Key Decisions for Investors

• Investors should evaluate opportunities across the entire data center value chain, including operators, specialized hardware manufacturers, and industrial REITs, to gain exposure to the sustained, AI-driven capacity expansion.
• Given the direct link between data center growth and energy consumption, portfolios could be strategically positioned by increasing exposure to utility providers and energy producers, with a particular focus on companies involved in nuclear power generation.
• Monitor the capital expenditure trends of 'big tech' companies like Alphabet, as their escalating investment in data center infrastructure is a primary driver of this theme and a key indicator of future growth in the sector.
• Consider the geographic concentration risk, as regions like Virginia may face power grid constraints or regulatory headwinds that could impact the profitability and expansion plans of both data center operators and local utilities.
