AI Servers to Outpace Traditional Hardware in Power Demand by 2027, Gartner Predicts
Global data center electricity consumption is projected to surge by 26% in 2026, reaching an estimated 565 terawatt-hours (TWh). This represents a significant increase from the 447 TWh consumed in 2025. Gartner forecasts that by the year 2027, the power demands of artificial intelligence servers alone will surpass the combined electricity usage of all conventional data center hardware. This trend highlights the rapidly escalating energy requirements driven by the proliferation of AI technologies and their associated computational needs.
The projected exponential growth in data center electricity consumption, driven primarily by AI workloads, signals a critical inflection point for global energy infrastructure. This trend necessitates a proactive re-evaluation of energy sourcing strategies, emphasizing sustainable and scalable power solutions to meet future demands. The increasing power draw raises questions about the environmental impact of AI's expansion and the potential strain on existing grids. Stakeholders must consider the long-term implications for energy security, cost-efficiency, and the feasibility of achieving climate targets amidst this technological acceleration.
