Gartner Says Data Center Electricity Consumption to Grow 26% in 2026 (www.gartner.com)

According to a recent report by Gartner, global electricity consumption for data centers is expected to surge by 26%, reaching 565 terawatt hours (TWh) in 2026, up from 447 TWh in 2025. This dramatic increase is primarily driven by rising demand for compute-intensive AI workloads, which is straining power availability. With worldwide data center power demand projected to climb to 132 gigawatts (GW) in 2026—up from 104 GW in the previous year—the ability to secure adequate power supply is becoming critical for organizations striving to maintain competitiveness in the AI landscape. AI-optimized servers are key players in this evolution, projected to account for 31% of overall data center power consumption in 2026. Their adoption is growing rapidly, with power usage expected to eclipse that of conventional servers by 2027. As the industry grapples with energy constraints that could lead to insufficient grid supply for future data center construction, Gartner emphasizes the need for infrastructure leaders to focus on efficiency upgrades, invest in high-efficiency cooling systems, and explore edge computing solutions to mitigate potential power shortages and support sustainable growth in this data-centric era.
