hint: An individual 18-hole course uses between 300,000 to 1 million gallons per day
If we can close 1 in 3 golf courses and have all the water we need for data centers - and then some - would that be acceptable to our society?
Do we desire so much golf that we'd prefer to stress our water systems instead?
This is a choice, alternative approaches do exist but we should definitely not assume that datacenter water usage is _always_ benign.
You understand, the water isn't used up? It's not even used up in agriculture. Even when you drink a glass of water, the water doesn't actually disappear, soon someone else will be drinking it. The same water that was on the earth when the dinosaurs walked the planet is still on the earth today. No need to panic about someone using water.
The only reason to be concerned is if someone is mixing the water with other chemicals at a rate faster than the natural filtration and then not paying for the treatment to purify the water again. But that is not an issue with data centers. Merely using water is a concern only for people who don't understand how matter is preserved, but a school physics book should dispel those concerns.
> Most data centers are closed loop systems, they circulate the water over and over again.
The linked article talks about >500 million gallons used by one large Google AI datacenter in a year. It's nice that most are closed loop systems, but if it's such a common thing to do then why isn't it done by default with all those AI datacenters? How cheap is water for Google that recirculating it is not a no-brainer?
However, the source of the water can be "used up" faster than it can be replenished, such as in the case of some aquifers
