The AI Boom Is Driving a New Era of U.S. Power Demand

Global data-center electricity demand is growing at a remarkable pace, and no country is driving that growth more than the United States. The Energy Institute’s 2026 Statistical Review of World Energy helps put the scale of the change into perspective.

For the first time in the Statistical Review’s 75-year history, it reported global data-center electricity consumption, using data from S&P Global Energy Data Center Electricity Demand Has Nearly Doubled in Five Years According to the new data, worldwide data-center electricity demand reached 787.8 terawatt-hours in 2025, up from 658.2 TWh in 2024. That represents an extraordinary increase of nearly 20% in a single year. Go back to 2020, when global demand was 410.8 TWh, and the scale of the expansion becomes even more striking: data-center electricity use has increased about 92% in just five years, representing an average annual growth rate of nearly 14%.
