It's misplaced to be angry about datacenters themselves. There IS value being created, or people wouldn't use the tools.
Construction creates jobs, manufacturing the machines in the buildings is a huge global industry; the value people gain in their work and play is considered worthwhile by them individually.
In the aggregate it all happens in a boring building shaped like a box, mostly built out of the way for economic reasons, and which if well engineered can be pretty efficient for what it does for the human race.
Maybe they should have been smarter but you operate with more information, you can pay brokers to convince the villagers to sell all their pigs and now the villagers starve, they will find someone who promises to make things right and they will burn your SPAM factory.
But for who and where is it realized? Ireland’s massive data centers aren’t there to serve Ireland’s tiny population. The value is exported overseas and profits realized overseas.
So what really matters for Ireland (and any country/region hosting these data centers) is whether the benefits in terms of capital spending + the few ongoing jobs created outweighs any increased electricity and environmental costs faced by everyone else.
While I do think there is value being created, I think this form of argument is not as watertight as it appears at first glance. Humans are very capable of behaving irrationally.
I think there is a lot of harmful, negative “work” being done by AI today. Creating fake videos for Facebook, running girlfriend bots, automated scams, etc. Even employees just trying to be at the top of their employers’ AI token leaderboards. (So last month, I know). There is legitimate value being created, but I don’t think it’s obvious that the positive value is swamping the negative value 10:1.
“There is value being created, or people wouldn’t buy the meth” - people do buy meth, quite enthusiastically, but any sane person would think allocating 23% of a nation’s electricity to a meth factory is a bad plan.
The grid is only looking after its capacity. When Grange Castle announced they're adding nearly 200MW of generation (for a nearly 1GW site) planners whoop with joy but that's 200GW of gas turbine for when they've spiked the wholesale price of electricity. It's not grid-surplus storage.
That sort of economic activity drives inflation. Well before you consider maybe-effects like job reduction.
Commensurate with their costs, including externalities? That very much remains to be seen.
If you don’t want your landscape vandalised with windmills and powerlines, go nuclear. Especially where the weather is consistently miserable, not conducive to solar power.
Data centers pay sub-market rates for electricity (as well as getting tax relief, generally). Generally, they use so much electricity that more infrastructure needs to be built. Who pays for that? Not the data center. The utility's capex is spread across all customers (sometimes minus the data center).
Then the utility needs to generate moer power or buy it from elsewhere. That's typically at a higher rate than it's currently getting, which raises the average cost of electricity for everyone. But again, the data center is getting a discounted rate so you have a water bed effect raising everyone's prices there too.
And for what? Maybe a few dozens jobs. The "value" being created is for multinational corporations who likely won't pay anything in taxes for it.
Data centers should be taxed for the land value they allegedly create. We have precedents for this sort of thing, most notably imputed rent. So if you spend $300 million on a building that lasts 30 years, that's worth $10M/year+. Then there's all the compute hardware. Assume $700M amortized over 7 years. Well, the imputed rent is at least $110M/year in base costs, so likely $150M+/year.
All this adds up to it should have to pay tens of millions (and maybe as much as $100M/year) in taxes.
Contrarian to the article or to other HN commenters
This article reports on facts, i.e., the CSO data primarily. It also mentions the existence of controversy
It is not taking a position for or against anything
What does it mean to be "contrarian" with respect to an article like this one
To me, this weird defensive behaviour, i.e., absurd attempts to "argue in favour of data centers", is what raises a red flag
The reporting of facts on energy and water use, i.e., data, triggers this behaviour from HN commenters, as opposed to being triggered by the people who are protesting or campaigning against data centers. This article and many others like it have no hint of "anger" whatsoever. The authors are not taking sides in any debate
Then we have companies actively trying to conceal data about data centers. This sort of behaviour is, IMHO, a red flag
If data centers "have value" and are needed despite their impacts, and the proof of this is that "people are using AI" then what's the problem
Why respond to articles that simply report usage statistics (cf. responding to angry protesters or legislation aimed at regulating data center construction)
The article is not taking a position for or against the construction and operation of data centers
They all have the same issues:
1) Pricing that doesn't account for externalities.
2) Those who bear the consequences are not those who reap the benefits
Because I guarantee you the people who pointed out that plastic surgery was covered have ideas of what that should be.
Plastic surgery can include burn and emergency surgical scars (trauma surgeons are just trying to keep your insides in and your outsides out, and then they have to run to the next patient to do the same), and hair transplants can include head injuries or cancer surgeries in young people in addition to vain old men.
When we discuss things like this in political arenas, nuance goes out the window and you're contributing to condemning little girls to walk around with giant patches of missing hair and people to tolerate visible scars that will absolutely be used to illegally discriminate against them for jobs that would allow them to afford their own procedures.
Water and power are priced by third parties, if they aren't passing some cost on to datacenters thats not the fault of datacenters.
>Those who bear the consequences are not those who reap the benefits
Super broad statement that cannot be meaningfully tested. Your power goes up, but your ISP has more and better peers, your emergency services have redundant vxc's between redundant sites, your steam games are cached more locally, your data is hosted in country rather than overseas and hundreds of other little benefits. A lot of which would cause greater whinging if they suddenly evaporated.
Either entitlement to the doctors/engineers labor or a house one doesnt own.
I dont think externalities is the most useful model for thinking about this because it is easy to construct a more favorable hypothetical. That doesnt mean one is entiteled to it.
Or about 11,000 GWh which is about 4% of California which means without the theatrics:
California has 4x more data centers than Ireland.
California: ~810 watts per person. (278,000 GWh / 39.4 million people)
Ireland: ~690 watts per person. (32,000 GWh / 5.3 million people)
We have air conditioning and that may be why we use more POWAH
edit: I live in Ireland
If they're so productive, make them eat the cost and lead time so we can all have a cheap, functional electricity grid. It would be so easy to mandate no new data centres unless they can procure their own renewable sources of electricity.
Heck, Google itself only expanded in Ireland back in the 2000s in large part because they worked on acquiring Colt to build their European CoLo in Ireland, and data centers now represent around 18% of Ireland's total GVA [2].

The country could easily solve its electricity problems with nuclear power. They can ask South Korea for help who built four reactors in UAE with 12 years which now provide 25% of the country’s electricity.
So has Ireland made an agreement with them in some way?
I’m just imagining that if there’s no local value for three beyond some temp construction jobs and a handful of service jobs, surely they can just bilk them until they leave. So I imagine data center companies only locate where they can get very safe terms?
I'm sure they work up a sweat but probably not on the same order of magnitude
If they have successfully avoided what they consider "externalities" thats a different matter. Like, polluting.
Would have appreciated a bit more context too. This sounds very serious, but how does it compare in energy use per land area across countries? Or in absolute use? Maybe Ireland is just small? Maybe not very densely populated? Maybe efficient in its energy use otherwise? Maybe all of these?
I also find the tone interesting. It's as if there was a threshold being approached [0], or if the rate was accelerating. But it's kinda the opposite?
> Their share rose to 23 percent in 2025 after passing 20 percent in 2023 and 14 percent in 2021
So from 2021 to 2023 (+2 yrs) the jump was 6pp, and from 2023 to 2025 (also +2 yrs) was 3pp... meaning the expansion rate in usage share has slowed to a half? I could easily imagine a similar article celebrating. Once again though, visual: https://imgur.com/a/0eR3bl6 -- using the actual raw data instead. Basically what the article should have been. You can see the amount of change attributable to DCs being higher than 2025 from 2020 through 2023. 2024 was a significant drop, and 2025 is between the two.
And what's with the random timeskips for the absolute data? Here's 2015, 2019, 2024, 2025, but not 2023 (only %), not 2022, not 2021 (only %), etc. So annoying. If we're throwing numbers around, then let's do it properly gents. The data is all available ^^ [1]. No need for untraceable quotes from a spokesperson; literally just a few clicks and a handful of agent prompts.
[0] Not only is there of course no threshold to speak of, the entire narrative framing is up in the air. Why does it matter how much electricity DCs use (in absolute or relative terms), and who does it matter to? Ireland's electricity use energy mix was recorded to be a suspiciously tight majority "green" in 2024 at least: https://www.iea.org/countries/ireland/electricity - could use all the energy they wanted if it was green energy, no?
