In local terms its a fair bit of heating but zooming out it's a drop in the bucket.
According to Google, one ton of water takes about 730kWh to boil. So I think you’re off by an order of magnitude, it’s only ~450 metric tons.
(But this assumes that no heat is radiated away in other forms.)
My 1500W space heater could boil 4.32 gallons of water every hour. But it isn't.
It is not at all inaccurate to say data center consumption of water is a huge concern. Too many on HN seem to be puppetting industry lines without realizing it. Closed loop systems are still uncommon and come with their own problems.
But golf courses are about 2.1 to 2.2 million acres while data centers are between between 340,000 and 840,000.
But I agree with your point. We should be closing both down. They are both water guzzlers and polluting our environment
Trump has been neutering the EPA for a reason.
I don't know if HN is really naive or just pretending.
When AOC is waving a jar of brown water in congress she's being disengenous. Just like the killed Amazon office in NYC it's just gonna kill jobs.
Can you cite a source for this? I can't find it anywhere.
Companies are in the business of privatizing profits and socialising losses.
The industry is pushing a line about little to no use of water based on the "existence" of closed loop designs. But even the closed loop designs come with major drawbacks and require investment in waste water treatment infrastructure since they still have to "bleed the lines" monthly to get rid of the sludge that is now full of anti-freeze, PFAS, anti-fungals, and anti-corrosives.
I do think the tech industry would be wise to do more outreach and less sneering, though. Freakouts about AI (which ultimately is what this is) aren't "rational" but they're eminently "reasonable". This isn't like electrification or aviation or the internet or whatnot (technologies that had clear, tangible benefits that everyone could see and understand), there is real discussion happening, by real experts, about essentially all non-physical labor being replaced!
And... what do regular folks get from that? Talking to robots doesn't look like a quality of life improvement!
Basically we in the upper stands here are having a "Let Them Eat Cake" moment, and we should stop. Things are getting ugly.
When I see a protest over a golf course opening, I'll take data center water use concerns seriously.
The data centers the industry wants are all going to get built. People are being hypnotized by concentrated minority interests in specific spots in the country. The only big picture thing about it is the left-populist sideshow it's created.
If that was the case then why are the majority of data center projects getting scrapped?
https://gizmodo.com/data-center-project-cancellations-quadru...
Why are insiders saying they only expect about 10% of data center projects to ever be completed?
Why is 2026 already shaping up to have less than half of planned data centers break ground on construction?
Local community opposition is a big driver but so is permitting and infra procurement.
https://www.datacenterknowledge.com/energy-power-supply/why-...
All of this is inconvenient to big tech's "inevitability" narratives.
That seems very untrue - multiple areas have already banned data centers, and senators like Bernie Sanders have proposed stopping data centers nationwide. This is just the next phase of NIMBY-ism. Alternatively, source that the "data centers the industry wants are all going to get built"?
> I've seen fiercer opposition to a 4-story apartment building than to some of these data centers.
I'm guessing you're referring to rather cherry-picked data? I've seen data center opposition making even the national news, but I don't recall any '4-story apartment buildings' opposition doing so? And senators like Bernie Sanders are proposing halting data centers nationwide - are there any similar proposals to similarly outlaw such housing construction nationwide?
> People just like opposing development.… When I see a protest over a golf course opening, I'll take data center water use concerns seriously.
Agreed.
A lot of the "sneering" I see from everyone who isn't an investor or an executive is a consequence of resistance to outreach. It's very difficult to discuss subjects with people when many now interpret factual explanations as propaganda and reassurance as manipulation.
By the way, plenty of people feared electricity a great deal (and it wasn't exactly implemented safely when it was new). In the 90s, many people also thought the Internet was a temporary fad, a mere novelty that would fade in some years.
The industry is actually doing real work on water issues in response to these complaints. Big tech companies are funding projects that will allow them to replenish more water than their datacenters consume. This isn’t actually that hard of a goal for them to meet, because as we know, the amount of water we’re talking about isn’t much on a national scale. Regardless, this will mean companies making some positive change in the communities where they build datacenters.
Anyway, all of this is a distraction compared to the real problem of carbon emissions. It confuses me that environmentalists are getting sidetracked by the water use distraction here when more natural gas and coal plants are coming online.
AI does have clear tangible benefits everyone can see and understand! That's why ChatGPT has 800M+ actives! Those people aren't just experimenting anymore, they're getting real value. I myself ask models questions about all kinds of things many times per day, it's entirely replaced search engines for me. It's much more immediately useful than something like aviation which created a lot of noise and risk (objects falling out of the sky!) yet took many decades to become available at a price point ordinary people could afford.
That seems needlessly pedantic, even for HN. I genuinely thought the scare quotes were spelling out the distinction I was making, but for the record:
"Rational" is used in the sense of "derived from logic", or "correctly understood". "Reasonable" is used in the sense (this is very common in legal paradigms, for example) of "an understandable opinion", or "an idea likely to be held by a typical person".
Actually it's a completely insane idea that can't be reasonably discussed.
The way they are operated, they do.
But at the macro level, it is not really a big number so far. From ~2.48 million in 2023 to ~2.37million now. Or a 5% drop in employment in 3 years.

Not being negative. But isn’t there existing highly reliable data that already exists for this?
However, "user reports" on that map clearly conflate the two, also reporting small, established sites in urban areas, etc.
Both are attempting to dismiss something useful and important, over trivial and manageable issues, mostly for culture war reasons rather than rational reasons.
Data centers are loud, raise energy prices for everyone around them, and use drinking water in tremendous quantities.
This isn’t a culture war, this is a class war.
Edit: you might be a bot. No comments in the last 47 days, then a string of hard-pro data center comments in the last week.
It also accepts user reporting of new developments, breaks them down in several categories (tracking proposed, operational, under construction, etc).
And eventually it can also track more information about them, specific to their cases (amount of water and energy used, pollution reports, etc). E.g. it has information like "1.2 GW AI factory broke ground May 12, 2026 at Eastgate Commerce Center (Little Blue Pkwy & MO-78). 400 acres, up to 10 buildings. ~1,200 construction jobs / ~130 full-time. Multi-billion-dollar investment; $150bn taxable industrial development revenue bonds secured." for some.
Brockovich is an environmental activist. Her project uses the public as a source of data for the map ("community reports")
DCR does not
EDIT: NO! Wth is this map? I have to click to expand the clusters. Ah well, all is good.
The code is interesting though, it's not minified, it's very readable, and nicely indented with lots of comments.
The curated data center list is just some inline JSON.
The javascript uses var instead of let or const, I'm not sure if this is just style choice, or there is some code post processing.
It doesn't use react, AI seems to almost always opt for react for front end design, unless told otherwise.
Like I get it looks a lot like apps built with AI but weren't LLMs trained on real website and a metric ton of website templates?
Is it possible they used a template or other UI library?
It's just vibes. There really are no reliable, simple criteria to determine if something was made with AI, and that shouldn't be surprising, since the whole point of LLMs is to mimic humans' work.
For code, I haven't read as much slop so I'm not as sure but one big tell is an unusual number of basic & unnecessary comments. And if it's version controlled, hilariously long commit messages with multiple sections.
It's more reasonable to suggest that a mismatch in tone or register between the style of writing and the venue it's being published in could be an indicator of AI, and it's possible that people misidentifying these tropes as being AI indicators per se may themselves be suffering from a filter-bubble effect, e.g. someone who doesn't typically read long-form writing might only be encountering conventions of long-form writing in AI-generated content, and misattributing them to AI in itself.
That itself isn't such a great criteria on some sites where you have different userbases who interact with the site in different ways. For example, Reddit has a large "old guard" userbase that treats it like a traditional message board, with longer-form and more in-depth discussion, along with a lot of more recent users who treat it like Twitter, and expect everything to be short and informal. Users in the latter group misidentify posts by those in the former group as AI more and more frequently.
I wrote a whole post about it. Tldr: "I dont like this shit so it must be AI". BENEATH. EVERY. FUCKING. POST.
https://write.as/shantnu/llm-witch-hunts-are-getting-really-...
The text (especially the "About" section, key concerns, and Erin’s quote) reads like strong AI-generated or heavily AI-edited copy. It has that clean, structured, persuasive style common in tools like Claude, ChatGPT, or Grok. Many observers on Reddit and elsewhere noted it “looks 100% designed by Claude.”
Not this shit again. Someone writes in clean English, people on HN are like iT muST bE Ai caUSe NoONe wouLD wrITe lIKE tHAt
All noise, no signal.
I 100% agree. And I notice you are being downvoted by the LLM Witch Hunt Committee.
One side effect of higher density is less footprint on the building to exhaust the heat, which is one reason (the main one being efficiency) that cooling towers and indirect evaporative cooling are favoured over air cooled condensers which leads to large amounts of water consumption.
Cooling towers are also much quieter than air cooled condensers which is a significant factor near any residential areas. It would be great to see more use of data center waste heat for process or district heating to save on water consumption.
Another issue with AI training in particular is huge (multi-MW) swings in power consumption at the start and end of each training run which must be a nightmare for the sparkies.
https://github.com/pytorch/pytorch/pull/132936/changes#diff-...
The power an "AI data center uses" in a single rack used to be, or is still in many cases, the power draw of an entire room or even floor.
Going from a few megawatts to ~10GW.
I believe clusters of dots with no reference links probably are duplicates in many cases. The ones that are ground-truth are the ones where site names and owners are listed or where a supporting article is linked.

Just one random Google result:
For most people it is just a thing that produces crappy facebook memes, has made certain parts of life more dystopian - like job interviews, and people keep saying is going to take away your job and the jobs of your children. And energy prices keep going up.
If you can't see why AI is unpopular you're just very out of touch.
* if it's serious, what in the world do you eat, to compare farming, with AI datacentres, on equal / comparable footing in terms of necessity and efficiencies -- or call farming a "heritage business"? :->
Failing to invest in datacenters now is going to mean paying more for the same consumption later. IMO it's best to let the hyperscalers take the hit from the initial depreciation. Sure the alternative gets you cheaper wheat or corn or whatever but that's coupled with an absurdly large premium if you're then blending in brand new CPUs and GPUs.
there's lots of ways food production is malevolent. the animal cruelty, the worker abuse, not just its environmental impacts.
i don't know. my point is that, this kind of stylistic aesthetic vibes stuff about datacenters is kind of bullshit. i'm not the only one who is saying this. are people in the places with cheap electricity near urban centers that are appealing to datacenters and seeking to ban them also going to ban bad farming operations from their communities? that's a LOT of farming operations! i can come up with some way that almost all farming operations are malevolent. no. they're not going to do that. i don't think they should.
you can have a national policy for this kind of stuff, because the consumers and producers are in different places and our way of geography self-determination is kind of stupid. if it's a market failure because of how the borders are arranged - which happens a lot with environmental stuff especially! - don't let these little bitty communities decide.

> WILLISTON, N.D. – Gov. Doug Burgum today announced the construction of one of the largest data centers in the world near Williston as North Dakota continues to emerge as a hub for high-performance computing, including cryptocurrency mining.
> The Atlas Power Data Center being built by FX Solutions Inc. is part of a $1.9 billion, multiyear project that will require more than 100 workers during the two-year construction period and create more than 30 permanent jobs, according to Richard Tabish, president of Missoula, Mont.-based FX Solutions. Atlas Power, an operator of high-density facilities serving cryptocurrency mining and high-performance computing utilizing alternative power generation, will own and operate the data center following its completion.
> ...
> The first phase of the project will consist of 16 buildings, each 350 feet long by 30 feet wide, to house tens of thousands of servers that will conduct high-performance computing using 240 megawatts of electricity. Phases 2 and 3 call for expanding to 500 megawatts and then 700 megawatts, adding additional buildings and servers.
And later...

> WILLISTON, N.D. (KFGO) – Residents west of Williston were hopeful for a few hours on Tuesday, June 20, after the Williams County Commission voted unanimously to instruct the local power co-op to shut off electricity in a portion of a local cryptocurrency mine. But Corey Seidel said he knew the effort had failed by nightfall, when the servers were still operating at their usual levels.
Or the offices of ads agencies defacing countless public spaces, injecting noise into every activity and wasting billions of hours combined of everybody's life?
AI is also the new thing currently being forced on basically every person and upending society. It shouldn't be surprising it's on the forefront of people's minds or that they might want to try to prevent it.
Why?
So we can destroy as many jobs as possible in as short an amount of time while nuking the environment from orbit and funneling trillions to china for the hardware?
The fact that you position anti-ai as a “left” thing means you’re not engaging with this seriously anyway. The environment isn’t a left-right thing. Jobs aren’t a left-right thing.
This page must be hosted from a data center as well...they could add a star to the map for their own hosting?
How much electricity does their site use, etc? I've seen counters like this before, I think, about the electricity a site uses based on the weight of the page, etc.
"...you said on an iPhone. Heh. Gotcha."
Datacenters provide very high utility with very low per capita externalities. There’s really no reason to care this much about them.
Brokovich might not know it. But her web people certainly used AI to build this site. From the Emojis, cards, to the single colored left border.
In what fairytale land does this describe the US today?
That seems a bit bizarre, since people opening new facilities are usually responsible for paying for their inputs with their own funds -- if merely increasing demand for power or water is itself generating externalities, that implies that there's a much more fundamental economic problem that needs to be resolved.
Why are you ok with spending $100 on groceries but not $100 on poison?
Software ate the world, now the world eats software.
ie it is in the economic interest of the writers to tap into (and foment) the FUD around "data centers."
If slop is more expensive to produce, maybe there will be less of it clogging up the digital commons.
Something like 20 years on we’re still hearing that “most” bankruptcies are caused by medical bills, even though that study (authored in part by Elizabeth Warren of all things!) was methodological nonsense.
I also wanted to add useful and accurate tools on things like local noise, water or grid impact. In addition to actually monitoring progress via satellite imagery and building a basic graph model for filling in missing attributes.
The reason why I stopped was that I significantly underestimated the effort required to complete such a project to the standards that I wanted to. As you can probably tell the site itself is AI assisted but all of the information was collected by hand which just takes time that I no longer had (~30 mins per site). The only way this would have made sense was as research project or something which sadly didn't line up.
there is almost no reason to build them in the US even without this luddite bullshit.
