The marginal water consumption of a properly implemented data center for its liquid cooling is almost zero.
People confuse water needed for power plants that power the data centers to the water need to operate the data center itself (cooling). https://t.co/fYYynr0dGp
This is your friendly reminder that data centres don’t actually need water. They need a cooling system and are using water because it’s the cheapest way to do it.
