“When data centers use water for cooling, one of the most important metrics is how efficiently they use that water—meaning how little water they use for each unit of compute. Amazon announced that its global data center operations used just 0.12 liters of water per kilowatt-hour (L/kWh) in 2025, a rate that’s over 7x more efficient than the industry average of 0.84 L/kWh.

In other words, we use far less water per unit of compute than others in the global data center industry, which as a whole accounts for less than 0.5% of all industrial water use globally. 

And we’re continuing to get even more efficient year over year. These efficiency gains are the result of years of investment in custom cooling technology, smarter systems, and a commitment to minimize water use wherever possible.”
