Amazon’s data centers used 2.5 billion gallons of water last year

What happened

Amazon disclosed that its global data center operations used 2.5 billion gallons of water in 2025. This figure represents a 2 percent reduction from the previous year despite increasing data center activity. Amazon reports water consumption at 0.12 liters per kilowatt-hour of electricity used, providing specific transparency on water use linked to energy consumption. This comes shortly after Seattle put a one-year moratorium on new data center construction—a move supported by some Amazon employees due to resource concerns.

Why it matters

Water use in data centers is becoming a critical operational and regulatory pressure point as AI workloads and energy demand grow. Amazon’s disclosure reveals the scale of water draw tied to cooling and power efficiency in cloud infrastructure, a detail rarely shared publicly. The modest reduction in water use despite capacity growth suggests ongoing efficiency efforts but also highlights the limits of current technology and practices. Operators and investors should note that water availability is now a tangible constraint that can influence data center siting, build-out speed, and operating costs, especially in regions facing drought or regulatory clampdowns.

What to watch next

Expect tighter scrutiny on water use from regulators and communities as more AI-capable data centers are proposed. Seattle’s pause reflects a growing trend of localized limitations that could slow expansion in key markets. Watch for how Amazon and competitors respond with innovations in cooling technology, shifts toward less water-dependent designs, or relocations to areas with more ample resources. Water metrics tied to energy consumption may become a disclosure standard, influencing funding and procurement decisions where sustainable infrastructure matters to customers and shareholders.
