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

Seattle just a year later data center moratorium that some of the Amazon employees pushed, Amazon he shared the amount of water its data center uses, he says for the first time. I’m worried about water use and energy use looking at the new arguments for building AI data centers, Amazon says its global operations consumed 2.5 billion gallons of water in 2025 at a rate of 0.12 liters per kilowatt-hour of electricity, down two percent from 2024 as a whole despite expanding operations.

Amazon also claims to be using water better than some of its Big Tech competitors – this figure in Amazon’s report points to Microsoft, Google, and Meta’s data which shows each using more water per kilowatt hour than Amazon did in the past few years.

Google was used extensively; however, it seems that the mentioned data is focused mainly on Gemini AI datacenters, while Amazon describes all of its services. However, Amazon’s data does not cover direct water use for the electricity that supplies its data centers, or things like water use from new data centers.

Amazon says that “about 90 percent of the time” its data centers use air-conditioning, and they use evaporative cooling during the “hottest hours of the hottest days,” while also increasing the heat tolerance of its servers. Amazon says its data warehouse is seven times larger than it uses, based on figures adjusted from peer reviewed paper released last year.
