Amazon has disclosed the water consumption of its data centers for the first time
Amazon has released information for the first time regarding water usage at its data centers around the world. By the end of 2025, the company’s data centers had consumed approximately 2.5 billion gallons of water, which amounts to nearly 9.5 billion liters.
This amount of water is comparable to the annual needs of a large city with several hundred thousand residents. The published data has drawn attention to the resources required to operate data centers and develop artificial intelligence technologies.
Water Use for Data Center Cooling
The information was released amid growing attention to the environmental impact of artificial intelligence and cloud technologies. Most of the water is used to cool servers that power digital services and artificial intelligence systems.
Despite the active expansion of its data center network, Amazon announced a 2% reduction in water consumption compared to 2024.
The company also reported that the average water usage was 0.12 liters per kilowatt-hour of electricity consumed. Amazon believes this result is better than the industry average.
The company emphasized that its data centers are cooled using outside air about 90% of the time. Evaporative cooling systems using water are primarily used during the hottest periods of the year, when natural cooling is insufficient.
Plans for Water Resource Offsetting
In addition, Amazon announced its intention to return more water to local communities than the company uses in its operations by the end of the decade. To this end, some facilities have already begun using treated wastewater instead of drinking water.
At the same time, the reported volumes remain significant. According to experts, 2.5 billion gallons of water could cover the basic annual needs of a city with a population of about 150,000–200,000 people or provide irrigation for several thousand hectares of farmland.
This was reported with reference to The Wall Street Journal.
