- Amazon revealed that its global data centre fleet consumed 2.5 billion gallons of water in 2025, equivalent to 0.12 liters per kilowatt-hour of electricity.
The figure represents a 2 percent decrease from 2024, despite the company adding new facilities. The data comes from a report released shortly after Seattle imposed a one‑year moratorium on new data centre construction, a move supported by some Amazon staff.
The disclosure matters because water use is increasingly scrutinised alongside energy draw in AI‑intensive builds. Amazon argues the decline shows improved efficiency compared with several rivals, though the absolute volume remains huge.
Even with a modest efficiency gain, the water bill for a single megawatt‑hour stays sizable, leaving room for further scrutiny.
