Just to be contrarian: what we're talking about is "electricity use from economic activity". This should be good for Ireland but they'll need to build energy capacity to keep up.

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.

Of course value is created, the problem is that the value is not created for the people who endure the issues and the pricing is apparently wrong. It is similar to building a SPAM factory somewhere people live on pork, paying higher prices for the pigs and buy all the pigs but not enough for the people who sold you the pigs to use the proceeds to increase the number of pigs or replace them with some other source and as a result you just created a famine.

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.

> There IS value being created, or people wouldn't use the tools.

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.

> There IS value being created, or people wouldn't use the tools.

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.

And that's grand, but when these things contest for the same resources I use (electricity, natural gas, water, rolling countryside unblemished by pylons), and I already see my bills soaring from a pair of absolutely unnecessary wars, I worry.

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.

> It's misplaced to be angry about datacenters themselves. There IS value being created, or people wouldn't use the tools.

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.

Yeah this is just completely wrong.

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.

"Just to be contrarian: ..."

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

Isn't this a similar issue of doctors raised by taxpayers money doing hair transplant and cosmetic surgeries instead of working in much less profitable hospitals with sick people or European scientists and engineers risen by public education working in American tech companies or super rich people from all over the world buying all the homes in London which is valuable not because of its resources but because of the people there and now causing housing problems?

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

In certain Asian countries, medical education is 100% covered but you must work at a public hospital for X years. I honestly think it’s very fair. If tax payers full funds your education, it should be mandatory to work in public services for X amount of years.
What kind of plastic surgery are you looking to gatekeep?

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.

>Pricing that doesn't account for externalities.

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.

The common thread in your examples is the idea of entitlements.

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.

That is about 3% of California's total energy usage

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

What fraction of Irish GDP is linked to datacenters? If I remember correctly from the pre-AI world, datacenters were at the heart of Dublin's industrial strategy, and they were credibly linked to a double-digit fraction of production.
I'm actually quite surprised that California only has 4x as many data centers, with CA having more than 7x the population (not to mention being pivotal in the Information Age)
My electricity costs 34 cent per Kw/h and I can’t afford solar panels or a renovation to air to water heating while the government insists we shouldn’t use oil / coal anymore nor logs or turf to heat our homes

edit: I live in Ireland

That's 7x the cost that I pay in the Pacific NW. Where are you?
It's crazy that people have to eat the long payback time to switch to renewable, while these wildly profitable (maybe?) data centers can just drink excessively from the grid or switch on natural gas turbines, and skip the lead times/upfront costs.

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.

Ireland has been a data center hub for decades - especially thanks to the IDA successfully wooing Microsoft back in 2007 [0], and it helped played a role in helping Ireland partially recover from the AIB and housing collapse back in 2008 and become the tech hub it is today. Heck, it was the corneestone of the IDA's tech FDI policy back then [1].

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].

Ireland consumes roughly 40 TWh per year, that’s less than the production of four EPR reactors or two times Hinkley Point C.

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.

And got electricity price hike last year, and now few weeks ago again, from ~25c kwh, to around 35c kwh! They say its reliance on fossil fuels. Not just that, think Ireland has one of the most expensive broadbands in the EU!
A similar thing happened in greece, but not with data centers. The railroads, airports,shipping ports were privatized and bought by foreign investors. Now the money from those services leaves the country making the greek economy poorer and weaker.
A few years ago I was reading a recruitment report and was surprised to learn that Ireland is a large source of data scientists, so it’s no surprise really
How do the data center people protect their expensive data center from colossal rate hikes? They can’t just pick up and move.

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?

Is there a snowball effect where a big AWS region attracts more usage? Those snowballs are more significant in smaller countries?
The very first country in EU who will make electricity dirt-cheap will win the "Sovereign EU AI Tech" war. That includes produce cheap electricity, cutting the redtape and curbing the Unions mafia. So .. not happening. Back to the US ...
They chose to add the word "guzzle". They could have just written "Irish datacenters now use 23% of the country's electricity". But they made the editorial decision to add in "guzzle". What's the word for this type of propaganda, where they add in some sort of adjective that wasn't needed, in order to prime the reader on how to think/feel, rather than just objectively reporting the facts? What are the odds that the content of the article is objective and factual, given the decisions they made with the headline?
Good work by them. An incredibly clean use of power with strong revenue. As industries go, this is a pretty good use of land and energy.
I read this as 'Irish Dancers now guzzle....'

I'm sure they work up a sweat but probably not on the same order of magnitude

Do they pay for it, and the consequent infrastructure cost increases? If they pay full commercial rates or adjusted rates for behaviours which are net beneficial to the supply process, then isn't this just another form of revenue?

If they have successfully avoided what they consider "externalities" thats a different matter. Like, polluting.

This article could have been a stacked bar chart with a caption. Maybe even should have been. Matter of fact, here you go people: https://imgur.com/a/s9KZRuQ (yearly version with 2015 as the anchor: https://imgur.com/a/f9ypK4W) -- there's also another likely more illuminating chart below, focusing on the YoY differentials.

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?

Canada seems better positioned for datacenters since they can power them locally with a multitude of options and not impact the local grid.
Good, force the world to build more energy production and mandate all data centers have to be powered by solar+batteries.
Electricity exists to be used, and we have essentially infinite free energy from nuclear power. Why are we wringing our hands pretending like we're going to run out of electrons? The days of hauling and burning ancient organic material to generate power should be over, and all these guilt-based arguments fallaciously require you to accept that as a premise.
also they need the tax to pay for the Irish Navy to prevent Putin from cutting the fiber
We need global minimum tax.
Guzzles or sensibly sips?
Ah the old "country's worth of electricity" comparison... Keep in mind that Ireland's entire electricity needs could be covered by a one nuclear power plant (3.8 GW with 4 reactors). IOW, you could offload all Irish datacenters by connecting them to a single nuclear power reactor (~900 MW), a small building that has a footprint of under 50 x 50 meters for the reactor, and another of 100 x 50 meters for the generator.
