Amazon first discloses data centre water use at 9.4 billion litres a year

Amazon for the first time disclosed the amount of water it used to run data centres worldwide, saying it consumed about 2.5 billion gallons, or roughly 9.5 billion litres, last year. The company said its data centres used an average of 0.12 litres of water per kilowatt hour of electricity, and that total water use fell 2 percent from a year earlier. Critics note the figure excludes indirect water use at power plants and during construction.
