    From the article:

    > The European Energy Efficiency Directive (EED) obliges data centers with an installed capacity of at least 500 kilowatts (kW) to report data including their energy and water consumption. In practice, few do so, despite the directive being in effect for three years.

    I do not understand how that is even possible.

    If any law is supposed to have any practical impact on the society, it needs to be enforced. Otherwise it is a guideline at best, not a law.

    I think what would help is for these companies to each receive strict and hefty fines for non-disclosing the electricity and water consumption data they are obliged to disclose.

    I assume that after that they would report all the required data very quickly.

    • pjc50 0 minutes ago
      National governments kind of suck at enforcing these. In some cases, like the notorious Ireland Apple tax shelter, they may not want to enforce the rules because they feel they are benefiting from the evasion.

      This kind of basic regulatory work is pretty thankless even when it's important. But I suspect the toxic politics of data centers will kick up some enforcement action sooner or later.

      (Why is it so toxic? Well, the explicit promise from AI companies of mass unemployment combined with higher electricity prices, and maybe even destroy the world https://www.theguardian.com/technology/2026/sep/09/anthropic... is why.)

      It's probably because directives have to be read into law at the country level.

      (Directives are binding on states. They transpose them into national law, possibly adding additional clauses as it goes past (EU directives set a minimum standard, not a maximum) at which point they're binding on people.)

      Nobody ever said the EU was efficient. Look for a deadline for that transposition on the original directive.

    • semiquaver 33 minutes ago
      Perhaps this article is one step in the process of forcing disclosure. The Dutch parliament has recently (April 2026) clarified its law implementing the EED.
    • ExpertAdvisor01 18 minutes ago
      Because it is an EU-DIRECTIVE.

      Directives are not the same as regulations .

      Directives are goals that must be achieved by adapting existing national laws or introducing new ones, and that takes time.

        Sadly, the EU is also lax when it comes to enforcing regulations. See GDPR.
        • close04 4 minutes ago
          No as much lax as lacking resources to deal with widespread violations. They probably focus on the most egregious cases.

      My account is banned, so for whomever having [showdead] on:

      European directive is not a law, it's a directive.

      It's up to the national governments to create applicable laws that are to the letter and to the spirit of a European directive. Then national bodies will start applying the law and govern its implementation/adherence.

      An by "up to" I mean they are obliged... eventually.

      • throwayaway 11 minutes ago
        It is not, I can clearly see it without it on.

        And I wouldn't be so sure on being 'eventually' obliged, someone has to enforce it for that to happen and it's not looking like anyone has profit in it

    • Pragmata 21 minutes ago
      The purpose of these laws is to give the state the option to crack down on anyone they feel like at any time. They are not meant to be obeyed, and that is obvious to anyone with eyes.

    Playing the devil’s advocate: don’t “freedom of information” laws mostly apply to government agencies? If so, why would a private company provide this information?

    I personally believe at the very least the water usage is heavily overblown compared to the agriculture industry. Elecricity is a different issue, and governments should consider reporting requirements or something like that.

    Being angry with datacenter providers is not the solution. And they also need to be built somewhere, and that place is probably best where electricity is abundant and/or cheap.

    • n4r9 56 minutes ago
      > the water usage is heavily overblown compared to the agriculture industry

      Data centers tend to concentrate their water usage within urban areas, causing a strain on local resources. The value of their output is much less tangible. Their water consumption scales up around tenfold if you consider the indirect usage from generating the electricity.

      But on the other hand; yes, it would also help enormously if people ate less meat.

      • Aurornis 4 minutes ago
        > causing a strain on local resources

        By “strain on local resources” are you just stating the fact that they use resources? Or are you trying to imply that it causes problems for those resources?

        Companies don’t just buy land, connect to water and power, and then the utilities get caught off guard when the water system is suddenly strained by water going somewhere. There are processes for approving this before connection.

        If a new project is causing a “strain on resources” then the utility planners have failed that community.

            “Metropolitan area” is doing a lot of work. Every metropolitan area I’ve lived or worked in has had industrial areas, too. Those industrial areas have buildings that use a lot of electricity, water, or natural gas and produce a lot of noise.

            This isn’t some unusual outcome. It’s like one of those maps that purports to show one thing but really just shows population density.

          It's not black and white as it looks.

          I'm personally willing to change my life to help the planet and nature in general to the point it doesn't affect my wellbeing (as in health and safety). For me, personally, the problem is not changing per se, but people finding no amount of change enough, always moving the goalposts with "but, what if" clauses.

          The problem with datacenter water use is the state of the water leaving the data center. Agriculture and meat industry can reuse the water multiple times from cleaner to dirtier processes and return it to the nature with reasonable processing.

          The additives used by datacenters in some cases can't be filtered or processed out practically or in economically viable ways, so the water returns back as unusable, esp. if they get water from a body of water and return it with added chemicals the process gets very damaging.

          • Dylan16807 3 minutes ago
            Additives like what?

            We're talking about water that's released in general use, right? I would expect a closed cooling loop to have some biocides but have almost none of that leave the system.

            And one datacenter had a weird bacteria that one time.

            Why would any water be returned? Datacenters (and literally every industrial process that requires cooling) use water for evaporative cooling. The water evaporates, then returns as rain elsewhere.

            The only water being "returned" I can think of would be from the intermittent or continuous blowdown systems to maintain TDS levels; but blowdown is a small fraction of the water consumed and is typically returned back via the city sewer system.

            • n4r9 16 minutes ago
              Roughly 80% of the water evaporates into the atmosphere. The remaining 20% is flushed out of the system to remove mineral build-ups and sent to local treatment plants.

        At first you had me, but then I realised it's not true if the price is building more data centres! That was just a trick to make the climate worse! Grr /s

    • black_puppydog 1 hour ago
      Actually your premise is already wrong, although to be fair I'm not sure what bearing that has on the conclusion.

      Here in France at least, companies can also be subject to FOIA requests for information pertaining to contracts they have with public entities. E.g. if a city publishes a tender to run tye local bike share program, then the company that gets the contract may have to directly answer (some) requests about that program.

      But like I said, not sure if this applies to data centers which are, iiuc, mostly private ventures.

    • sschueller 47 minutes ago
      The are resources acquired from the government in most places. You have to be able to plan and expanding capacity which requires public funds.

      I live right next to a waste valorisation plant[1]. They have to exactly specify what amount of water they use and what amount of water they then send out to the waste water treatment facility. It also has to be clean to a very specific standard before it leaves which is also checked.

      We have datacenters in Switzerland too, but very little outrage or debate because there are strict rules in place in most places. They can build all they want but it costs significantly more to meet environmental requirements.

      The valorisation plant next to my home has a water cooling tower/fans significantly oversized just to make sure the noise is keep under the required level.

      This is a Dutch website and here in the Netherlands we have demand issues. In these same areas where issues exist, data centres are being planned and built. There are waiting lists now for normal businesses who want a new connection to the net, or connections with more capacity. These are lists waiting for capacity to become available: The demand on the current net is already too high.

        This is something that certain AI advocates are refusing to acknowledge. The concerns are legitimate and can only be alleviated with open access to information by companies and the state. Then it can be clear that the project is doable or not, and let the people decide, as they are the ones that will have to live near it.

      They don't need to be built at the scale they're being built at. That's the problem.

      • dansquizsoft 17 minutes ago
        Not sure why you think your finger-in-the-wind wind understanding of future AI compute demand should trump the projections of companies who actually operate in this area?

        But if you do end up being correct, then the data centers in question will just sit partially or fully idle, using no / a tiny fraction of the electricity and water they could use (which as others have said on this forum, water usage concerns are massively overblown in most data center builds anyway)

      People keep comparing datacenter water use to agricultural water use, and it doesn't make sense to me. I can't tell if it's a bad-faith comparison or if people really know that little about how water is used in these industries.

      The vast majority of agricultural water use is either tapped directly from groundwater, drawn directly from surface sources, or rain. The vast majority of datacenter water use is processed water from a municipal water utility. In other words, it is meaningless to compare the two, because only one is competing with residential use, and so only one is worth caring about.

      That's not to detract from serious concerns about e.g. overutilization of the Colorado River, or the idiotic practice of irrigating deserts, but it is to say that comparing datacenters to agriculture makes very little sense.

      • ajsnigrutin 33 minutes ago

      > Being angry with datacenter providers is not the solution.

      Belittling criticisms that way is childish and doesn't address a single one. Literally nobody on the whole planet, at least in public discourse, is using "I am angry" as an argument in any of this. Yet it's the first thing that is always brought up. It's just a cheap, thought-terminating stereotype.

    • hnedeotes 49 minutes ago
      You are totally right to point this out, and I apologize for the whiplash. Let's clarify exactly how overblown data centre water usages is compared to the agriculture industry.

      In data centres all that water is so that some wimpy cunt gets to hit return after spending no more than 5 minutes in an half baked prompt so he can insert the answer into his pitch deck, or PR review — and now with pacing the frontier models, he actually doesn't need to insert it, it's inserted automatically wherever it might fit. When it comes to agriculture, that is to produce things like food. This requires obviously much more water, which means that's what we really should be cutting down. Agents don't need food so the solution is just to replace humans with agents.

      If you have any other stubborn question resisting clarification just hit me up, and I'll explain it to you immediately and clearly.

        This is extremely inappropriate on HN. Or anywhere, really.

        I can think of a few reasons that companies might not share data. A big one is that people have no idea what a responsible amount of water usage is, so your information will be weaponized no matter what.

  • unglaublich 1 hour ago
    They refuse it because if they would say "1 million liters a year!" the knee-jerk reaction will be completely predictable even though that's just tiny compared to a small swimming pool or industrial or agricultural site.

    The debate is completely based on emotion and anger right now, so sharing information will only give the emotional/angry folks more mud to throw with. The majority of people has no clue about how to put things like energy use and water use in perspective, and they're also not interested in doing that. Because they have decided to green-wash their AI-fears as environmental fears... which is a big fat joke because datacenters aren't significant polluters or consumers compared to almost all other industries.

    Look, I get it, many people are afraid of the societal impacts of AI, or distrust it in another way. But let's be honest and focus on _that_ instead of naively acting as if our anti-datacenter sentiment comes from environmental concerns (the last few decades have shown we don't GAF about the environment).

    • yourusername 40 minutes ago
      >Look, I get it, many people are afraid of the societal impacts of AI, or distrust it in another way.

      In the Netherlands it is not just about AI datacenters, even before the rise of AI pushback against Meta's planned datacenter made them cancel it. There has been a lot of criticism of the municipality that allowed Microsoft to expand its datacenters. The argument is that this is a small country that already has to make tradeoffs to get to its desired energy mix (wind turbines near cities on land) and then these datacenters are built that consume the power that is generated by sacrificing the little remaining open space. In the last few years there is actually a electricity shortage in some regions so "we can hook up this 200 MW datacenter but not your house" is a bad look.

    • vidarh 4 minutes ago
      I'm all for data centres.

      But they should be made to report this. AND their use of water should be regulated - they don't need to use any water at all, it's just cheaper for them - and they should be contributing enough to mitigate negative effects on energy prices.

      The problem isn't data centres. The problem is not pricing in and regulating externalities, whether caused by data centres or other things.

      It would also quickly show us who actually cares about the environmental effects and who are using it as an excuse.

    • pbasista 31 minutes ago
      > They refuse it because ...

      It is completely irrelevant why they choose to refuse to provide this information.

      From what I understand, disclosing this data is not optional. It is a law. And if they have willfully chosen to operate in a country where such a law applies, they have to obey that law.

    • goda90 51 minutes ago
      If they are taking reasonable steps to mitigate consumption and pollution then they should be able to clearly explain that to the public. The fact they won't suggests they aren't.

      Just because people haven't cared about the environment before doesn't mean they shouldn't start now. And just because there are worse existing polluters doesn't mean we shouldn't resist new ones.

      A new golf course used to be seen as a great thing to have in your back yard and now we know their pesticide use increases the risk of Parkinson's. People are waking up and caring more. We need to have a sustainable society, not a profit obsessed one.

      A swimming pool requires maybe 60k liters a year...
      • vidarh 9 minutes ago
        One cubic metre of water is 1000 liters. A typical 25m swimming pool ("short course" / half of olympic size) is 20-25m wide. That's at least 500 m^2 surface area. At an average depth of only 1m (very conservative even for a recreational pool), that is 500,000 liters just to cycle the water once a year. Estimates I can find suggests 3-7 times as much as that on a yearly basis for a typical recreational pool.

        So unless you're talking about a tiny private residential pool you're at least an order of magnitude off.

      • xaitv 8 minutes ago
        And besides that: news sites love comparing water usage to things like bathtubs, the average household or swimming pools. The headline would likely be "datacenter uses 100 swimming pools of water per year!" and not "datacenter uses 6 million liters of water per year!"

    I think it would be helpful for people in this thread to understand the differences between EU Regulations and Directives :

    • EU Regulation: A binding legal act that applies immediately and identically in all EU countries as soon as it takes effect, without needing national laws.

    • EU Directive: A legislative act that sets a mandatory goal that all EU countries must achieve, but allows each nation to pass its own laws to implement it.

    It takes time for directives to take effect, unless a member state's national law already implements them.

    EU is in such a weird position. They are realizing that software, robotics, and generally automation through AI is the industrial future, but they seem to be paralyzed to actually start the build-up that will feed that frontier industry and economy.
    • cbg0 43 minutes ago
      Assuming you are right, the "build-up" of more physical datacenters isn't really the difficult part, training frontier models is. The open-weight Chinese models are several months behind frontier models at this stage and as long as you're not interested in burning cash to stay in the lead you can just wait it out. Many signs (upcoming ridiculous IPO figures and benchmarks) point to the current LLM paradigm reaching a plateau.

      I think that currently the EU is focusing on strengthening itself from a military perspective due to US policy shifts, so the EU just doesn't have the funds to divert to AI without impacting day to day life of people, thus prioritizing safety and perhaps energy production, as electricity is considerably more expensive here than in the US or China. If you ask the people who vote, they'll put safety, grocery and gas prices way above EU's LLM capabilities.

        > so the EU just doesn't have the funds to divert to AI without impacting day to day life of people

        The US Government is not a major funder of frontier labs (who are almost exclusively VC and private money funded)...

        > as electricity is considerably more expensive here than in the US or China

        Yes, there are government policy reasons behind why this is the case.

        > If you ask the people who vote, they'll put safety, grocery and gas prices way above EU's LLM capabilities.

        Fair point, these are good things to focus on. However, EU citizens are going to love it when there are no frontier-tech opportunities left in their countries, with everything in this area having to be imported from the US and China (note that just because Chinese firms make open weight models available now, this could easily change very quickly in the future for a variety of reasons).

        "Data center" is really just a proxy for industrial compute capacity and it's a resource like any other. It's a factory.

        If the EU does not build their own factories, then they will be reliant on factories built elsewhere.

        • thephyber 15 minutes ago
          The EU already has several hyperscaler data centers and many more colo-style data centers. Plenty of compute power exists in EU; this new generation is about purely inference capacity.

          In the US, the political backlash against data centers is also about the inability of government to be transparent about these buildouts (eg. City councils signing NDAs and building commissions quietly approving development plans without community input), the inability for utilities/regulators to actually hold data center developers to promises made (usually regarding resource/ utility usage), more complaints about affordability (cost of utility bills rising), additional hate against the unlikable tech CEOs (who aren't charismatic and whom have a long list of previous violations), fear of what AI will bring (the promised white collar revolution, promises of "infinite AI immigrants" in an age where immigration has been demonized), etc.

          Only a few of these are about the "factory" itself. Lots of them are about the people trying to retain some control of their communities. Some of them are about the speed of the buildout (eg. compromises in water use / plumbing and noise / pollution created by the ad hoc on site electrical generation).

          The data center CEOs are starting to admit that their NDA-blitzscale strategy may have backfired because communities are pissed and the NDAs prevented anyone from making a positive case for the buildouts while the rage was boiling over.

  • LogicFailsMe 14 minutes ago
    In the US, the rhetorical trick is to include the 3.4T* gallons of water utilized for power generation along with cooling (160B) to make this number super scary when water was utilized for power generation because it's a good cheap relatively clean power source so the datacenters were built near hydroelectric plants.

    We can't do much about the 160B, but we could do a lot to build more power generation and storage. As just one example, in west Texas, natural gas is flared into the sky en masse from depleted oil wells because methane is a more powerful greenhouse gas than CO2. Some sites could be tapped to hit hundreds of megawatts to a gigawatt of power generation. And any power you don't need can be exported to the Texas power grid so it can make money the day you turn it on. And if you're willing to spend a little more, you can sequester the CO2 and make the power generation mostly green.

    Cue crickets from Silicon Valley on this one because it's neither nuclear nor renewable, but the crypto people love it so I would guess they'll eventually come around. That they haven't already is one facet of my disenchantment with tech culture. Their absurd belief in Star Trek Voyager-like scenarios playing out with AI in the next decade the other major one.

    *Which is slightly more than the 3.3T gallons of water Americans used to water their lawns. So, ya know, where's the outrage?

      This figure is about the water consumption only. The estimate about the electricity consumption, in that same article, is much higher than that.

      The main problem is, in my opinion, that those are just estimates. If we are supposed to accommodate the current and potential future needs, we need real data. Not estimates.
