Inside a data centre: Fourth Class students receive tour
From the outside it is a non-descript building without any signage in an industrial estate in west Dublin.
Inside the Equinix data centre, there are rows of servers supporting everything from internet banking to social media, and from artificial intelligence to tv streaming.
The first thing you notice inside the building is how noisy it is, and how cold it is.
Chilled air is pumped up from underneath the floor to keep the servers cool.
There are more than 80 data centres in Ireland and they are a vital part of the economy but they are also massive consumers of energy.
"At the moment in Ireland, 22% of all electricity is going to data centres," said Rosi Leonard, Friends of the Earth.
"So that's more than all urban homes in the country, it's huge."
"Ireland is also a global outlier. The EU average is around 2% of electricity going to data centres, we are almost 20% over that," Ms Leonard said.
Data centre providers insist they are taking steps to lessen their environmental impact.
"We are doing some grid response initiatives," said Warren Delaney, Ireland Operations Director, Equinix.
"We would be asked at peak time during the day at certain times of the year to disconnect our data centre load or partial load from the grid to help with the pressure that might be on the grid at the time," Mr Delaney said.
A group of local school children from Scoil Ghráinne Community National School in Dublin 15 got a tour of an Equinix data centre today, to learn what exactly happens inside these facilities.
"I learned that this place holds all the internet and if the power goes out, it doesn't go out in here," said Graham Phelan, Fourth Class.
"You use things like Snapchat, Xbox, Instagram and TikTok, they are all powered by a data centre," said Sharon Olaitan, Fourth Class.
Their classmate Audrey Gudz also learned a valuable lesson from the data centre trip.

Age checks to be enforced on video sharing platforms from July
Video sharing platforms based in Ireland will face new regulatory obligations to verify users' ages before showing adult content from July, according to Coimisiún na Meán's Online Safety Commissioner. Speaking on Prime Time, Niamh Hodnett said the commission will be "supervising" the platforms to "see what measures have they put in place" from 21 July. The new measures are part of Coimisiún na Meán's Online Safety Code, which requires that platforms hosting pornographic or violent material ensure such content is not accessible without robust age checks. Platforms "have an obligation in relation to age assurance and also parental controls as well as content rating," Ms Hodnett said. "What we require from the July date is either age estimation or age verification, and it has to be effective," Ms Hodnett said. "To date, all the measures have been self-declaration... That's not an effective form of age assurance or age verification." Ms Hodnett also outlined several approaches that could meet the new standards. "That could be done by facial recognition, for example, or cognitive skills, or capacity testing - a maths or puzzle skill or something like that. It can also be done by hard age verification... uploading IDs, whether they're digital IDs or actual copies of passports or driver's licenses." The Commission will not mandate any specific technology, but Ms Hodnett said the systems must be "robust, privacy-respecting, and holding data for no longer than it is necessary". Concerns around privacy were also addressed. Ms Hodnett explained that age verification could be handled through secure intermediaries, not directly by the platforms themselves. "It can be provided to an API or almost like a middleman," she said. "That would just give a signal or a token to the platform as to yes or no, that person is over 18. You wouldn't be sharing your passport or your driver's license with the particular platform... these interfaces or these APIs can just give that signal, and that can be done in a privacy-compliant way." The Commissioner confirmed Ireland is working with European and UK regulators to align age assurance standards. "Together with the European Commission and fellow regulators across the EU... and our colleagues in Ofcom in the UK... it's all coming together this year in relation to effective age assurance." She also pointed to the EU's planned digital identity wallet, which is expected to launch by the end of 2026, with a test version available later this year. The system will allow users to verify their age without sharing personal identification with platforms. While age verification has dominated headlines, Ms Hodnett was clear that it is only one part of Ireland's broader online safety strategy. "It's not the silver bullet to solve all problems of online safety in this space," she said. "There are other measures that we require in our code, such as effective parental controls... restrictions on who can contact a child or whose content can be seen in relation to a child, because we're concerned also about grooming and child sex abuse material." Asked whether stricter enforcement could drive young users toward the dark web, Ms Hodnett acknowledged the risk but said public education was also key. "We provide tools and information on our for parents, for children, indeed for all of us," she said. "We also have education materials that we shared with every school in the country." The first enforcement deadline under the Online Safety Code begins 21 July, when granular requirements for age assurance and other safety measures come into force.

Kraken becomes first crypto giant to get Mica licence from Central Bank
The move means that Kraken can now trade across the 30-member European Economic Area as a fully-regulated entity. Andrew Mulvenny, the Dublin-based general manager of trading platform for Kraken, described the move as a 'huge milestone and a massive achievement'. It comes after a run of bad news for Ireland in the crypto space, with Coinbase following Gemini out of Ireland as its main regulatory hub in recent months. Coinbase chose to switch its EU regulatory base to Luxembourg, saying it preferred the regulation climate there to Dublin. Gemini said the same thing, favouring Malta. Both of the crypto giants had originally established their European regulatory hubs in Dublin in 2023, before Central Bank governor Gabrioel Makhlouf described cryptocurrencies as a 'Ponzi scheme'. IDA chief executive Michael Lohan said Kraken's Mica licence from the Central Bank here was important. 'This landmark moment strengthens Ireland's standing as a leading fintech hub in Europe,' he said. 'We value Kraken's ongoing investment and engagement and we look forward to further collaboration as the digital finance sector continues to grow in Ireland and across the EU.' The chair of Blockchain Ireland, Lory Kehoe, also put a positive light on the Kraken news against the background of regulatory uncertainty in recent months. 'This is a win for the Irish ecosystem,' he said. 'It strengthens Ireland's position in the EU's digital finance landscape, creates pathways for high-quality jobs and gives clarity to start-ups, institutions, and investors building in Ireland.' ADVERTISEMENT Mr Kehoe also predicted that more Mica licences would be issued by the Central Bank. A spokesperson for Kraken said that the Mica licence represented a 'pivotal milestone' for the San Francisco firm. 'Being the first major global crypto platform to receive authorisation from the Central Bank of Ireland (CBI) affirms Kraken's commitment to building for the long term,' said Kraken co-CEO Arjun Sethi. 'Over the past several years, our team has worked tirelessly to meet the CBI's gold standard regulatory expectations. This licence reflects that effort and places us in a strong position to expand our product offering, grow our institutional and retail client base and deliver secure, accessible and fully regulated crypto services to millions more people across the EU.'

July deadline for higher tariffs may be extended
US President Donald Trump could extend a July deadline for higher tariffs on imports, the White House has said. Mr Trump had set 9 July as the deadline after which punitive tariffs on a range of EU goods will take effect, with the EU promising some €95 billion in retaliatory countermeasures. Asked if there were plans to further the pause, Press Secretary Karoline Leavitt told reporters: "Perhaps it could be extended, but that's a decision for the president to make." "The deadline is not critical," she told a media briefing. She said the president could "simply provide these countries with a deal if they refuse to make us one by the deadline". Ms Leavitt added that Mr Trump can "pick a reciprocal tariff rate that he believes is advantageous for the United States". On the progress of trade negotiations, Ms Leavitt said US Trade Representative Jamieson Greer is "working very hard" and has had "good and productive discussions with many of our key trading partners." Taoiseach: Strong appetite at EU level for US trade deal It comes as Taoiseach Micheál Martin has said there is a strong appetite at EU level for a trade deal with the United States. At a summit of EU leaders in Brussels, Mr Martin said: "Everybody within the European Union is focused on arriving at a negotiated settlement with the United States by the ninth of July, which I think is extremely important to give certainty to markets, certainty to investors, certainty to workers and industry. "Every effort has to be made to get a landing zone that we can live with. It's not ideal. It's not optimal. Europe doesn't want tariffs, but we have to deal with the situation that is before us." Ireland has sought to remove agrifood products, medtech and aviation from the EU's list of countermeasures, in order to protect important sectors to the Irish economy and to avoid provoking further US retaliation. The Taoiseach said: "There is no painless tariff war. Obviously, we have made a response to any retaliatory list. Europe has to be united going into these negotiations, and as these negotiations come to a conclusion, but I do genuinely detect an atmosphere that's focused on getting a deal, both on the US side and on the European Union side." EU diplomats have said a growing number of EU countries now favoured a quick resolution. Belgian prime minister Bart de Wever said: "A trade war makes both sides of the Atlantic poorer and is just stupid. So I support the approach of the Commission president, who always keeps calm and has negotiated for a result." "If that were to end in one-sided and unfair tariffs then we have to take proportionate and very targeted countermeasures." The EU is already facing US import tariffs of 50% on its steel and aluminium, 25% for cars and car parts, along with a10% tariff on most other EU goods, which Trump has threatened could rise to 50% without an agreement. The United States' only completed trade deal to date is with Britain, with the broad 10% tariff still in place. "There is a group of EU countries that want to protect companies by seemingly accepting something they have gotten used to - a 10% baseline," one EU diplomat said. One question EU leaders face is whether it should respond with its own measures to such a baseline tariff. The European Union has agreed, but not imposed, tariffs on €21 billion of US goods and is debating a further package of tariffs on up to €95 billion of US imports. Among the EU rebalancing options is a tax on digital advertising, which would hit US giants like Alphabet Inc's Google, Meta, Apple, X or Microsoft and eat into the trade surplus in services the US has with the EU. The bloc has a trade surplus with the US in goods. The Commission has proposed an EU-US deal to cut respective tariffs on industrial goods to zero, along with potential further EU purchases of liquefied natural gas and soybeans. Washington has shown little obvious interest, preferring to highlight items it considers as barriers, such as EU value-added tax, environmental standards and rules on online platforms, on which the EU does not want to move.
