Amazon Inc. reportedly utilized a staggering 2.5 billion gallons, equivalent to nearly 9.5 billion liters, of water across its global operations in 2025. This significant consumption primarily supports the vast network of data centers that power the company's digital services.
Focus on Efficiency Amid High Demand
Despite the substantial volume, Amazon asserts it is enhancing its water efficiency. The company claims a 2% reduction in water usage compared to 2024, even as its data center footprint continues to expand. This efficiency metric, measured at 0.12 liters of water per kilowatt-hour of electricity consumed in 2025, is reported to be lower than figures from competitors like Microsoft, Google, and Meta.
Free Air Cooling: Amazon's Strategy
Unlike some data centers that rely on water for cooling, Amazon emphasizes its use of a method called 'free air cooling.' This system draws cool air from the outside environment, circulates it through server racks to absorb heat, and then expels the warmer air outdoors. Joern Tinnemeyer, an Amazon data center engineering leader, likened the process to opening windows on a cool morning instead of running an air conditioner.
This approach minimizes the direct need for water in the cooling process, contributing to the company's claims of improved efficiency.
Path to Water Positivity
Amazon has publicly committed to becoming 'water positive' by 2030, a goal it states is approximately 75% achieved already. This ambition comes as the entire technology industry faces increasing scrutiny from governments, communities, and environmental activists regarding the environmental impact, particularly water consumption, of large-scale data center operations.
The company's disclosures highlight the hidden environmental costs associated with the digital economy and the ongoing efforts by tech giants to manage their resource footprints.
