Amazon discloses data center water use for the first time: 2.5 billion gallons in 2025

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

Amazon shared its global data center water consumption for the first time: 2.5 billion gallons in 2025, at 0.12 liters per kilowatt-hour. That's a 2% drop from 2024 even as operations expanded. Amazon also claims better water efficiency than some Big Tech rivals, pointing to a chart in its report. The disclosure came right after Seattle enacted a data center moratorium that some Amazon employees had pushed for. The post doesn't name the rivals or show the full comparison data.

Why it matters: Amazon's first global water disclosure is concrete and well-timed, adding new info. But it lacks peer comparison details and the topic is infrastructure-adjacent, a step removed from AI applications, so it lands at the featured threshold.
