No datacenters isn't about AI or even resources like water or power, it's mostly about real-estate and housing prices as usual.
If we listened to NIMBYs we would have no new infrastructure, no high density housing, no public transport.... oh wait.
I wonder, do you know how much energy or water is required to run a datacenter with direct liquid cooled systems?
Not the SOTA AI data centers which are popping up like mushrooms, a general ballpark is enough.
This is not a loaded question. Given your knowledge, you must be knowing much more than majority of HN.
Back when I was running my own startup I moved to Mascot, Sydney to be near Equinix SY3 that was being built which we had bought a decent chunk of committed capacity in. Mascot was originally an industrial area but was gentrified a lot over the last 20ish years but the datacenters, meat packers etc are all still there. It really adds to the charm of the place in a lot of ways, warehouses/factories that have been converted to cafes and breweries. Which is to say I don't think living near a DC is bad at all, they aren't very loud and they just look like big warehouses with lots of lights, cameras and no windows. Oh and security dudes.
Anyways. Yes. The hardware I am working at $DAY_JOB is all direct liquid cooled. The coolant that actually cools the hardware is closed loop, it's not expended. Which means you don't actually use any of it and it's considered good for the entire life of the hardware.
I normally don't directly talk about $DAY_JOB things because there are pretty strict rules so I can only use publically referenced sources but you can read a little bit about the coolant we use in this article [1].
The facility loop though is usually what people are worried about. A lot of datacentres that were built in low humidity environments use evaporative cooling which does indeed use a ton of water. However most data centers in more humid environments don't and either use loops that recycle the water but dump the heat (i.e rivers/lakes) or use closed loop systems with radiators etc. It's worth mentioning though that evaporative cooling is extremely power efficient vs most closed loop solutions so there is a tradeoff here. I don't think Google could achieve their fleetwide PUE (Power Usage Efficiency, basically measurement of how much power goes to things in a DC that isn't a computer) numbers without relying on it heavily.
Given the difficulties getting DCs approved in much of the world right now and the backlog on generation capacity (i.e power) almost all modern DCs are being built to use as little water as possible.
To give you an idea I think evaporative cooling of the type you would find in a state of the art Google DC with a PUE of ~1.1ish might use 1-1.1L of water for every kWh of actual equipment load (this is a back of the napkin estimate, don't hold me to it).
Conversely true closed loop will use approximately zero.
So yeah, evaporative is a big waster of water especially at GW scale.

“A backlash fuelled by misinformation and misunderstanding” is also just an academic jargon term for “my vision is superior, anyone who disagrees is out of stupidity, if they understood me they would agree.”
Sure sounds like foolish moral panic. Many of the responses here so far would be perfectly at home on bluesky.
People like my dad with no technical knowledge at all read an article in some rage-bait newspaper and it must be true (like foreigners took all your jobs, and the left-wing government wants to tax all your money and give it to scroungers).
If people are not taught how to ask "how often is this true" or "how much is this true" or "will this always be true", then they will fear whatever they are told to fear.
just an anecdote but what exactly do local residents gain here? a handful of permanent maintenance jobs?
No. Permanent sleep deprivation and probably tinnitus. It's sad, really.
Poorly designed cooling infrastructure is indeed noisy. There are lower noise versions exist, but they are expensive, and I don't think they can be that quieter to make a difference at that scale.
The water is mostly part of a closed system. Sure, you need a lot to build one, but once it's running it's pretty water efficient. The lack of green power is a problem, but as the article points out, you now have a large customer subsidizing the base cost of delivery, since they are only one delivery point, and they are financing new sources of power, which if properly regulated would be green power.
The noise is an issue, I will admit that. As is the fact that a lot of the power is coming from non-green sources. But the government could easily fix these problems with regulations that apply broadly, not just to datacenters.
(This is part of why I no longer help build them, because when I asked about reducing noise and using green power I was laughed at).
It seems with all the other battles to fight, that moving it 2km down the road and surrounding it with trees and parkland would knock the noise argument out of the window. At least in the US and Australia that really do have vast amounts of open space.
"The moral panic over data centres is foolish, filthy peasants!"
People fucking hate you and don’t trust you and are convinced, not without reason, that you have the specific goal and intention of destroying their way of life and ability to provide for their families. They also feel like they were never consulted in any of this and that nobody is representing their interests.
You can agree or disagree with that point of view, but unless you thrive on ignorance you might as well get your head around the fact that it’s likely a majority view in this country by now.
Consider for a moment trying to figure out why that is the case rather than pretending it’s not true or that it’s a mass delusion.
Ad-hominems in an Economist article. This reads more like an opinion piece than reporting. There are plenty of documented problems with water usage of data centres. Some can use it efficiently but it costs more to do so and many (most?) do not.
We are also in a time when most people would prefer to use that water for drinking, washing, cleaning… basically anything except data centres.
Don’t think many people are going to read this and think, “Gosh, I was a fool!”
But it does offer AI narration.
Are we calling TTS "AI" now?
lol
First of all, there are reasons apart from pollution, rising electricity prices and global warming:
These things make noise. Noise bad. Noise very bad for health. Maybe if post from Economist or Spectator villa no know noise!
Thanks for your attention to this matter and please continue to eat cake.
That's worked great for the datacenter misinformation so far.
There's not even an author on this article.
But you can listen to an ai narrated version of it.
The Economist has anonymous writers for almost every article.
But I think the effect will be that the companies building them will "sweeten" the deal for the local towns where they are building -- probably by way of taxes. And while that will be a drag on their development (by adding costs), the scale won't be bad enough to really hurt.
And in that sense, everyone wins. The locales will be happy to have the extra resources. And the ones that don't take the "bribe" -- or whatever you want to call it -- won't get datacenters.
(But I do agree that panic is overblown and counterproductive.)
Yes. And datacenter companies have to foolish to slow-walk doing this. When you are building a 10 to 50 billion dollar construction project, it may be worth giving the local town 100 million (plus 10k directly to every resident) to do with as they please, and it would certainly grease the wheels.
This is mostly an America problem right now because that is where everyone wants to build the DCs and it's the market with the most stagnant generation: https://en.macromicro.me/collections/26367/electricity/14247...
US electricity is 40% more expensive since 2022 https://fred.stlouisfed.org/series/APU000072610
Some AI datacenters can indeed be heard a mile away https://www.theguardian.com/us-news/2026/aug/28/datacenters-...
Amazon's new Texas AI data center could become the biggest CO2 polluter in the US https://www.techradar.com/pro/amazons-new-texas-ai-data-cent...
Relative to data center growth, the correlation doesn't match - https://ourworldindata.org/grapher/monthly-spending-data-cen...
More analysis here - https://www.wri.org/insights/whats-driving-us-electricity-pr...
But TL;DR - sounds like in the northeast / PJM it's load increases, in North Dakota increased load is causing drops in prices, California it's mostly from wildfire mitigation + insurance, natural gas oscillating across the US is causing price changes as well.
We have an entire generation of young people that went to college and got a degree hoping that they would be able to get a good job and live a comfortable life. However, that's not the case anymore and the fact that almost all entry level jobs are replaced by AI has created this sentiment among people that somehow AI is evil.
The problem is not that AI is evil, but most of the people would have to learn new skills and adapt because the profession or job they trained at college doesn't exists anymore.
Data Centers have existed way before mainstream AI. Everyone would binge watch the latest season of popular shows of Netflix and won't even bat an eye thinking how much water that has wasted.
isn't the problem then capitalism? the promise of AI is to deliver efficiencies, leverage, and consequent surplus. AI does not itself allocate the surplus.
There's a lot of examples of companies failing to deliver things they promised at this level like the FoxConn complex in Wisconsin. Making city leaders sign NDAs doesn't help this. People are more skeptical of future tax revenue claims and it's hard to sell a direct benefit of the AI itself when you spent two years talking about eliminating all white collar jobs. The trust just isn't there.
Given the classical liberal philosophy of The Economist, this just reads like scolding when their world-view is falling out of favor. Luckily for AI boosters, I think data center builders are adapting to reality.
I'm personally not interested in the details that you can't provide, that was not something I was aiming for, but putting a ballpark number for ~1.1L/kWh is very eye opening (I know it's not some accurate figure, but yeah). Considering a SOTA GPU uses somewhere from 700W to 2.5kW depending on the manufacturer and performance level...
Hope to meet you someday. Have a nice day! :)
I like Copenhill (https://www.visitcopenhagen.com/copenhagen/planning/copenhil...), where they decided that waste handling is not nice so why not make it nice by building a ski slope on it. I suspect that a bit more creativity could make people want data centres (free heating and hot water anybody? Hot spring baths? Free hosting for local schools and charities?)
It’s only NIMBYs and YIYBYs
Also see the Green parties / Greenpeace and the decline of nuclear power stations. We could have had clean, cheap energy across Europe and America, but the fear of nuclear is fully embedded in the public psyche.
The irony of this that it portrays everything referred to as a moral panic as something worthy of legitimate worry and/or outrage that was brushed aside by more influential socioeconomic groups.
Which now makes me wonder how many of the examples listed here qualify.
If I'm understanding you correct.
Of course. Esp. for the bigger datacenters which generate their own power and release large amounts of emissions to the atmosphere.
It's good that that air never moves and all this emission stays inside the cube formed by the ground, four borders of the datacenter and personal airspace ceiling prescribed by the governments.
Given that the datacenter operators run air purifiers and give the filtered out emissions to government (or licensed 3rd parties) for conversion to carbon credits, there's no harm done.
Just some local noise nuisance, and maybe some heat, but all of them are manageable. Residents can use earplugs and more powerful air conditioners to restore or surpass their previous life quality.
This is not only progress, but how one changes the world for the better.
The issue right now is the boom of data center building has them being built wherever approval can be had, rather than in more reasonable industrial locations.
It's reasonable to not want a data center built next to you in the same way it's reasonable to not want an iron smelter or pit mine built next to you. There are reasonable places to build data centers, pit mines, and iron smelters and it's not residential neighborhoods. Building them in residential neighborhoods anyway because they can, is what is forcing this issue to a head.
That and water usage building them in places with water issues. There are a lot of places in the country that don't have water issues. Data can be moved around the country quickly. The problems are solvable, but the builders are more interested in chasing short-term dollar than solving them. The opposition should hopefully reshape the construction into a more reasonable reality.
Like.. you came in invalidating the people, then, when called out, you say what is effectively "well their criticism is actually right".
And.. That's that. I guess. Are you sure that you're taking part in the conversation and not just stringing words together based on probabilities?
> In any case, even the noise worry is overstated: many viral videos of supposed AI data centre noise are really Bitcoin mines, not state-of-the-art hyperscaler facilities.
Are there really major differences between a hyperscaler, neocloud, and crypto mining data center in terms of noise pollution or other negative effects?
Most regular people have not been sold on the idea that more AI will be good for them or their families or communities personally. Instead all they hear is AI taking away jobs, and AI preventing high schoolers and college kids from learning how to read a book and write an essay. Most people think a world with more AI seems bleaker.
So people wonder why communities don't want this hulking, loud, energy-expensive data center whose main benefit is to hasten the arrival of this world they don't want?
Isn't AI the only way we get to that? Who is gonna do actual important work otherwise?
Instead the evidence of our own eyes tells us that AI seems to be worsening the K-shaped economy: a handful of Elon Musks will become trillionaires, a slightly larger number of engineers will become billionaires, and the rest of us will have fewer jobs and fewer prospects of upward mobility in a world where AI can do most entry-level work.
If you need your job to feed your family then what Sam or Dario is saying is quite literally a threat to kill your children.
Of course they’re full of shit, it’s more like a very useful business automation project but if you say stuff like that you can’t be surprised when people hear it and form highly rational opinions about it.
Soooo
You're building them, and you're agreeing that the biggest points of criticism are valid.
But.. some handwaving that the government should do something about it and also others are too doing bad things.
And your conscience is clear, huh?
They are powering it with turbines right, so if its next to your house it sounds like you're permanently in on the airport tarmac. Not great. I saw a video (not on the internet, but from them). It was pretty annoying. But it makes sense, there is no way a power delivery system in a developed country adapts so fast to such intense energy needs. Here in india, many 250Mw datacenters are put in places where a proper grid connection is itself coming for the first time, so the same problem is not there. And frankly there are way more noisy industries in poorly zoned mixed-industrial-residential areas here for generator noise to even matter.
You even note the problems, but then wave them away saying that "the government could fix them."
So have the government fix those problematic regulations first, and then the AI centres can re-apply for permission.
But what people are most upset about are water and power, which are the two least problematic things about datacenters.
* use a lot of water to build one
* the power is a problem
* the noise is an issue
* the power is coming from non-green sources
* the government could “easily” fix all this with regulations
Also can you tell us which chemicals need to be added to the outer and inner loops of the systems, and do the inner loop has the same losses or it is different.
If there's water loss into the ground, and if the water is treated with chemicals, is it required or is it in fact treated to remove these chemicals so the used water can be reused for livestock, agriculture, or non-consumable use in the cities like for watering greenery or other processes which needs water but can accept non-potable variety.
I also heard that there's a closed loop version for outer loop. Is it used widely in US, if yes, what percentage of the large datacenters use it? Because as I heard it, it's more expensive, but doesn't lose water as much.
Adding some references if possible is greatly appreciated so we can dive deeper, as the community.
Same is also valid for power usage metrics. I'm especially interested in how a datacenter full of 800VDC systems (aka Megawatt Rack) can be fed without any difficulty with our current power generation and transfer infra.
My personal criticism of data centers is mostly regulatory failure. The tech companies are choosing random ass states and stealing land from poor farmers instead of the traditional data center states like Virginia mostly because of tax breaks. The local government is just as if not more responsible for the issues with data centers. It's easy however to just point fingers at big tech instead of he underlying market failures in a lot of the states. The traditional data center states almost always have a supply of clean energy and water with a proper regulatory framework.
Its pretty obvious here that people decided datacenters were bad first, then went looking for justifications second.
The difference here is that data centers are both economically and environmentally extractive. People in the community, or at least in the surrounding area, will play golf there. Data centers are purely extractive, and that's why they have become so galvanizing. It's transferring probably the only real asset these communities have left, their open spaces, directly to the elite.
please, tell me more
> people in the community, or at least in the surrounding area, will play golf there
going to go out on a limb here and guess that net-net, a datacenter provides more benefits to a broader spectrum of society than a golf course does.
What is the exact value proposition of AI as it exists right now for the average person who lives where these things are being built? They don't even get jobs. With golf, they can enjoy the outdoors and escape a little bit.
That is the style of articles (interpretive analysis) that The Economist does.

Given that my sink cannot contain 20 gallons of water and that I do not even fill my sink full to do my dishes by hand, I cannot possibly be using 20 gallons of water to do my dishes when I do my dishes by hand.

I suspect the data center thing has become popular because it's been a long time since people have felt like they can effect change in government policy. Details and nuance are irrelevant, there are larger, underlying forces at work

In other words, since the USA endlessly debates everything, you might as well put out messaging that creates more FUD so that it opens up more chances they'll believe anything.
The dissonant mental state fuels the consumption that drives the economy.

People in China are also generally more excited about progress since it has actively improved their livelihood and wealth over the last few decades rather than slowly eroding it like it has in many Western countries. The government there makes legitimate investments in very visible and beneficial public works projects. Why would you be unenthusiastic about progress when you've been getting subways and high speed rail and cheap luxurious EVs everywhere for the last 20 years?
I find this article incredibly weak, glossing over a number of legitimate concerns brought up by data center opponents. This sentence in particular is pretty egregious:
> In any case, even the noise worry is overstated: many viral videos of supposed AI data centre noise are really Bitcoin mines, not state-of-the-art hyperscaler facilities.
Really? You think people are building Bitcoin mines, in 2026? Please.
Let's also be clear here: AI data centers could be a wonderful thing if we had a government that was legitimately focused on shoring up the national grid, transitioning to renewable energy, and building nuclear power plants. You know who is doing that? China: with more nuclear power plant projects underway than the rest of the world combined.
Instead, the US has an administration that started another middle east war for no reason resulting in higher oil prices, cancels renewable energy projects and permits left and right, and seems hell-bent on moving backwards in every way possible. Electricity prices in many states have gone up by double digit percentages. I don't see that happening in China. I don't blame anyone for being against data centers, even if it is "FUD."

The actual issue, as far as I see it, is the financialization of capitalism. When businesses prioritize creating value to the shareholders over creating value to the society, people naturally care less about their success. The degree of financialization also varies from country to country.
