The thinking on display in this thread is something like,

"I needed to add a billing address field to the order flow, so I suggested we use Kafka to process shipping requests. My boss said the form field should turn red if an invalid address was entered, and in response, the team lead objected that Oracle charged too much for MySQL. I checked for a pricing page but found a 'call us' form. The CTO decided to go with Kafka, and told us that landlines are an obsolete platform."

My biggest problem with the data centers getting built around me are that they are building new natural gas power plants to power them, that will be greenhouse gases and decrease local air quality. I would be a lot more ok with it if they were using wind or solar. And maybe built it somewhere that didn't have a water shortage.
reply
One being built near me is being built on public lands that are being sold off for datacenters. That's an additional pretty big negative (especially since the specific land was set apart as a wildlife habitat.)

I do really dislike that AFAIK almost all of these are being powered via burning fossil fuels. Any way you slice it, it's going to mean that locals end up paying higher energy bills.

It tells them exactly how much they have to invest in hardware buildout to stay competitive with Google in terms of raw compute.

This is right up there with being able to predict a competitor's total manufacturing capacity for the next year because you have hard numbers on their raw material purchase.

The ability to improve their data centers, of course. Google is the company that launched data centers with commodity components.
reply
And this one in particular is a high-ticket trade secret; it has been for decades, long before the AI push.

Power and water consumption number revelation goes directly to ceiling on maximum compute and relative compute efficiency. It's handing to every competitor on the planet (including China) "Hey, here's the raw situation on how far along we are on our total capacity to do anything."

... whether this should be a trade secret (since power and water are both shared resources with the surrounding community) is a reasonable question, but in the ecosystem where it is, Google having this data public and their competitors not is a problem.

Did your datacenter consume 9GW?

I get it, a lot of the older data centers consumed relatively little power. More than nothing but manageable like 1 or 2MW.

The reason for the "craze" is that the AI datacenters being built are monstrosities that consume way more power, an order of magnitude or more. And a lot of them are going up.

There were certainly 1GW DCs in the US 10+ years ago.

> I think the largest data centers consume about 1 GW.

The largest AI datacenters. And there are multiple planned that consume beyond 1 GW. In particular, I'm referring to the box elder county data center which I believe is one of the largest planned. [1]

Prior to these AI datacenters, 100MW would have been considered an extremely large amount of power for a single datacenter.

But also, 1GW is a huge amount of power. More than a lot of states use, and not the really small ones like Wyoming. Just for reference, steel mills use 40MW and there's about 8 of them in the US.

1GW is an absurd amount of power to consume.

reply
> But also, 1GW is a huge amount of power. More than a lot of states use

Not even close to a true statement.

EIA says that the lowest electricity use by state in 2024 was Vermont, at 5.5B kwh. That’s about 0.6GW, if you assume continuous uniform use. By the time you get to #48 (Hawaii) you’re over the 1GW mark [1].

According to the EIA, US utility-scale generation capacity in 2025 was 1.3 million megawatts [2], so assuming that these new 1GW datacenters were on the public grid, they would each consume about 1/1300th of the 2025 supply. Not nothing, but not nearly the dramatic impact that you’re suggesting.

For perspective, the Grand Coulee Dam has a generating capacity of about 7,000MW. Robert Moses dam in Niagara Falls does about 2700MW.

Fine, an exaggeration but not off by much.

If the Box Elder datacenter were a state it'd rank #19 in terms of power consumption (78 TWh).

It is correct to say these massive data centers will represent a significant percentage of US power consumption when built out.

I haven't done the math but if I see how many tokens I can burn per month for 100 USD it's pretty mind boggling to imagine how much capacity is being added by this build out.

This is not the place to discuss it but even in my wildest predictions I find it hard to imagine that we're really going to need all this capacity anytime soon (although I guess anything spare can go into training).

It’s not ‘spare goes to training’. These data centres are training first. Inference is really rather efficient, so not why datacenters are so big.

I'm sorry, I never worked in a data center nor lived near one, what's the obvious reason you couldn't dispute them? My only guess would be that Google really wanted to keep the amount of usage secret, but that'd only make sense if it was higher than expected not lower.

reply
Google never wanted to share details about their datacenters because they thought (think?) their power efficiency was a competitive advantage. So it'd be lower than you expect.

Also, they didn't want you to be able to guesstimate how many machines / computing power they had, for similar reasons.

reply
Right, they're so power efficient they don't want to tell the people around them how little water they consume or "not consume"?

People complain about new data center slurping up all local water and then neither Google nor representatives can say "No, actually we're not, here is the numbers", because Google doesn't want their competitors to guess how many machines they have in one of their data center? I'm sorry but that sounds very far-fetched, must be another reason parent wrote it was "obvious" they couldn't divulge how little/much water the place uses.

reply
You can assume that any company at a large scale will not want to divulge any information unless absolutely necessary. Doesn't matter if you or I think that it might not need to be secret or might not be competitive. Unless there is both an internal push, a need and a sort of proof dat the information can be released, it will never happen. You'll usually find thing that are simplified or aggregated for PR and marketing, or things that are required for legal reasons, but everything else stays internal.

It is worth remembering that it heavily depends on cooling system involved.

Traditional data centers have far smaller power density per rack and thus cooling requirements than AI datacenters; if you can use closed loop system without evaporation, water usage is very small. Difference is around order of magnitude

But if you want to fit maximum amount of compute in the space and need to dissipate it, evaporative based system will be far more effective space wise; especially if also for some reason you built it in hot place, rather than somewhere in the north

reply
I've been spending some time in Tasmania, Aus for the last few weeks and have been following the local debate regarding 3 data centres Firmus is planning on building here.

While on the surface, the proposals sound very efficient and low impact, as always the devil is in the details.

Standard operation would use closed loop cooling, relying on rooftop rain water to keep the loops topped up. However, the company has acknowledged that when ambient temperatures rise above a certain level (26C), they would need to switch to evaporative cooling.

The contract with the government also has a section where the company requires a connection to the state agricultural water supply as a backup [1].

When rainfall is plentiful and temperatures are low, as they often are in tasmania, everything is rosy.

However the state does experience periods of draught and thats where things get sketchy. Conflicts are likely to arise when a large investor in the states economy wants to start draining the local water supply to keep ai agents running at a time when crops and livestock are competing for the same resources.

Similar issues would arise regarding power. Firmus is proposing to underwrite an expansion of the states already extensive Hydro power network, but for that investment they would very likely expect priority access to the grid when supplies start running low.

Ok and? This wouldn’t be an issue if google et al would just share the numbers instead of hiding behind NDAs and whatever else.
reply
Are you sure? People think water for data centers is "consumed", like the output is sewage or something. Giving those people concrete numbers is not gonna change such misconceptions (and that's assuming they look at such numbers in reasonable relative terms in the first place).
reply
The majority of current large data centers use open-loop evaporative water cooling which does in fact consume water.

Most of the consumer water is evaporated but that leaves behind dissolved solids and minerals and so some of the water is used to clean that out. That water also often contains additives like biocides, anti-scale agents, and corrosion inhibitors.

This water is discharged into the sewer system or to municipal wastewater treatment facilities.

Here's an article on the various ways data centers can be cooled and what effect each has on water usage [1].

[1] https://www.fwpcoa.org/content.aspx?page_id=5&club_id=859275...

reply
Seems easy enough to report multiple numbers and be clear on what water comes in (can even separate initial filling/construction from ongoing usage) vs what gets lost and what comes out as waste. I think people can understand this and it isn't a good enough reason to not share the numbers.
reply
There are so many facets that numbers alone don't cover:

Are they drawing from a flowing source or an aquifer? Is it depleting a limited resource?

Is it evaporative or does the waste get discharged?

Is the waste water treated for the metal that it leaches from the cooling system?

Is it allowed to reach thermal equilibrium first or is the water discharged warm which can cause algae blooms or other problems?

reply
It is consumed because they evaporate it away and remove it from the local environment.

They easily could build near heating system or cooling the water down in another probably big facility close by and send it to the city

reply
Evaporated water stays in the water cycle though. It comes back down as rain, and returns to the water sources that were depleted (assuming these data centers are generally not using underground aquifers, which I think is true).
reply
You can't control the water cycle over a datacenter and its water source, it is a global system.
reply
Fair point. But if I had initially learned that google was putting data centers in and it recycled water and it was a minor amount I would be more receptive than hearing that google is bullying communities and hiding details behind NDAs.

Right, isn't that what sharing the information is about to show, that it isn't consumed? Show how much water they're adding to the ecosystem, since I'm guessing they'd have numbers on that, if that's how it works.

Not sure why this is being downvoted. If you noticeably distort the local economy then people are naturally going to want to know what resources you're consuming.

Worth considering in the current climate.

Largely because of how many times it could have been stated prior, given it had been a talking point for some time, and the lack of actual evidence (him saying something is not often taken at face value…).

Of course, they'd like the water thing to stay an issue as it distracts from others. The water problem has been concentrated on because even some of the most adherent climate change deniers recognise that water access is a significant problem in many areas, so it is an issue that can be usefully raised and won't get tied up in the human-caused-climate-change argument. Unfortunately concentrating on that could be distracting from other matters.

Data centers tend to be higher security facilities for a reason. Publicizing any of their technical specs isn’t really beneficial, especially when any numbers that are provided will be dismissed unless even more information is provided to back them up.

Correct. But they can't so easily without Google's (or other big tech companies) big legal departments to make challenging the excuses difficult.

reply
How does hiding water usage protect the facility exactly?
reply
The big hyperscalers always knew that eventually the tide would turn against them (for example when local towns noticed that the DCs didn't actually need very many locals to run the facilities).

They carefully hid things so they could expand for as long as possible, knowing that having the necessary footprint for services, cloud, and AI would be key to winning the race. When I worked at Google, our leaders were always "proud" they had built such a huge fleet (originally for search + ads but rapidly growing to a wide range of products and research) without competitors knowing just how large, because they figured eventually AWS and MSFT would realize they had to build out massively to handle the coming loads.

So they hide these things to stave off complaints for as long as possible.

reply
It’s not high security if everyone is mandated to do it. Power consumption, energy sources, water usage for coolant, waste water treatment plan, etc.

I think the disinformation is people thinking that data centers directly use vast quantities of water. What happens is the power use stresses water supplies in local areas.

Being paid well enough gives the mind an out from cognitive dissonance that doesn't involve actually believing the company narrative.

It offers the compelling counter-narrative of "yes, we're evil, but hell yeah this is lucrative af". That makes the ego even happier, as in that story, one is the clever mastermind playing the system, so we can reasonably assume that that path will be taken.

If that path is unavailable, and cognitive dissonance sets in, the other path left is actually drinking the kool-aid. The corp must be nice, after all.

(This all assumes that people do in fact want to do good and have a conscience, but for those that doesn't apply to, there's the sociopathy path as mentioned in the previous comment. Reality is slightly more murky and dynamic, but I'd argue that this rough if-ladder exists as described.)

Most data centers are closed loop systems, they circulate the water over and over again.

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.

reply
Sure the water is still somewhere, but its location is important for future use. US water reservoirs are at problematically low levels already.

The linked article talks about >500 million gallons used by one large Google AI datacenter in a year.
