Amazon reports 2.5B gallons of data-center water use in 2025, says it’s more efficient

Amazon published its first annual water-use data for global data centers, reporting 2.5 billion gallons in 2025 (about 0.12 liters per kWh), a 2% decline from 2024 as it expanded capacity. The company argues its facilities are seven times more water-efficient than the industry average and rely mostly on air cooling, with evaporative cooling during peak heat, but the figures exclude indirect water use at power plants and water for building new centers; Google reportedly uses more water per kWh in the cited charts, and comparisons often focus on Gemini AI data centers rather than all of Amazon’s operations, all against a backdrop of Seattle’s data-center moratorium.
