The Growth of Global Data Center Capacity

What We’re Showing

This chart visualizes the growth of global installed data center capacity from 2005 to 2025 (projected), based on data from the International Energy Agency (IEA).

Key Takeaways

• Global data center capacity is projected to reach 114.3 gigawatts (GW) in 2025, growing at an annual rate of 17.7%.
• In 2005, capacity stood at just 21.4 GW, meaning it has grown more than 5× in two decades.
• Electricity demand from data centers is expected to hit 485.4 terawatt-hours (TWh) in 2025, making up 1.7% of global electricity demand.
