What is the nature of the concern with water and data centres? Is it a justified concern?
12:37
So the concern really varies depending on if the region is water stressed or not, and also what technologies the data centre is using.
12:46
The amount of water a data center uses can be really significant.
12:50
And just to give a sense of the upper end, the Environmental and Energy Study Institute, they have estimated that a medium sized data center can use up to 110 million gallons of water per year for cooling.
13:05
And the largest hyperscale data centers, they can consume up to 5 million gallons per day.
13:10
which is the equivalent of a town with around 10,000 to 50,000 people, and that's per day.
13:15
So you can see that water consumption really varies by the size of the facility.
