Another data point. California pistachios consume about 500–600 billion gallons of water per year.

I've always found this a weird comparison. There is no more important use of water than providing food. I love tech and earn my living from it, but the importance of food cannot be overstated.

Its not a bad comparison because pistachios are a cash crop, not a staple crop. That is to say, pistachios aren't grown to keep people fed, they are grown for economic profit

the water cycle exists. unless data centers are being built in deserts or run off fossil aquifers the or other water constrained circumstance the waste is supurious. As other commenters have said closed loop cooling exists. Billions of motor vehicles run on water based cooling and consume virtually nothing once filled.

The entire environmental argument against data centers is largely bullshit. Sure, they shouldn’t be powered by gas or coal. And the local effects are significant. But the macro environmental effects are minor and the local effects can be resolved with the most trivial regulations.

Let's see the recent Guardian article: The UK government vastly underestimated the climate impact of artificial intelligence, it has emerged, after officials raised their estimate of carbon emissions from AI by a factor of more than 100.

According to new data quietly published this week, energy use by AI datacentres in the UK could cause the emission of up to 123m tonnes of carbon dioxide (CO₂) – about as much as generated by 2.7 million people – over the next 10 years.

That latest figure replaces a previous estimate – since deleted – that claimed emissions would reach a maximum of 0.142m tonnes of CO₂ in a single year.

I think the criticism here is that they're pumping that water in from the Colorado river based on a pricing schema that makes it artificially cheap t grow water intensive crops in a very arid region. If the pricing were modernized and rationalized those pistachios would be grown somewhere that has more rain fall. Moreover a lot of that water is transported with the pistachios out of the watershed so it creates 2nd order problems.

You could also argue that Amazon data centers are crucial commercial infrastructure that used for a lot of logistics necessary to move food around.

There are a whole lot of foods that are incredibly wasteful if you truly care about water consumption.

Saying "if it's edible then it doesn't matter how much water it uses, it's justified" isn't a good position to take.

You don't need pistachios. General compute is a few orders of magnitude more important to humanity's livelihood than pistachios.

This water usage argument against data centers is so specious I almost think it's spread as a deliberate talking point by DC proponents. Power consumption and effect on electricity infrastructure is so, so, so much more consequential and dangerous. It alone is way more than enough on which to base a very solid anti-DC campaign. The water argument weakens the whole anti-DC position by being so refutable. EDIT: with pr…

Didn't OpenAI say they thought it was foreign interference?

Personally, I find it ironic to see people going on and on about data centers on platforms like Threads, Reddit, and X. It's like, do you know where your data is going when you press that button?

And some foods are a lot more water efficient than others to produce.

I spoke to someone who owns data centers recently. He said that in hot climates, they run closed-loop to preserve water, so the actual water use is virtually nothing. In Chicago (where we have no water shortage), they consume water—but it just evaporates and re-enters the water cycle.

Yep, that's how they do it in here Vegas. Datacenter water use isn't the problem, the state law mandating 15% of electricity must be bought from the privately owned state utility monopoly is.
