Data centres, streaming and the carbon bill behind the Irish catalogue
A European evening of Irish or American television looks weightless: a tile, a Player, a phone on a train. The Irish electricity system does not experience it that way. Data centres consumed 23% of Ireland’s metered electricity in 2025, the Central Statistics Office reported on 7 July 2026 — up from 22% in 2024 and 5% in 2015. Their metered use rose 10% in a year, from 6,973 to 7,663 GWh, while all other customers together rose 2%. Urban dwellings, in the same CSO release, accounted for 18% of metered electricity; rural dwellings 9%. The machines that store and move catalogues now use more Irish electricity than the country’s rural homes. That is not a metaphor. It is a statistical release.
This piece is the climate-and-infrastructure half of MSMN’s screen file: how streaming, cloud and AI sit on a grid that already treated data centres as a security-of-supply problem.
The Irish exceptionalism is the grid, not the hobby
Ireland did not invent video streaming. It did become, by mid-2025 industry counts cited in legal briefings, the second-largest data-centre market in Europe, with about 1,150 MW operational around Dublin. EirGrid’s median growth path, as quoted in the same briefings, has the sector’s share of electricity demand rising toward 31% by 2034. The Commission for Regulation of Utilities imposed a de facto connection moratorium in 2021 and spent years writing a replacement. On 12 December 2025 it published the Large Energy Users Connection Policy (CRU/2025236). EirGrid’s Data Centre Connection Offer Process and Policy Version 3 (May 2026) implements that decision for new transmission connections at or above 1 MVA.
The bargain is explicit. New data centres must show they can meet at least 80% of annual electricity demand from additional indigenous renewable generation, on a six-year glide path from energisation, with a credible plan the system operators can test. They must also bring dispatchable on-site or proximate generation or storage equal to their maximum import capacity — a security-of-supply overlay, not a green sticker. Location matters: operators must consider local constraint. Friends of the Irish Environment, Friends of the Earth Ireland and ClientEarth have challenged the policy; William Fry’s 2026 note records a hearing listed for May 2027 and EirGrid’s warning that applicants who proceed do so at their own risk. The climate NGOs’ core complaint, as reported, is that the framework still locks in fossil plant. The CRU’s core defence is that connection policy is not an emissions cap, and that unconstrained connections would crowd out electrified heat and transport.
Climate Action Plan 2025’s electricity aims sit in the same paragraph as the glide path. Ireland’s carbon budgets are why the paragraph is a fight: IIEA and EPA commentary through 2025–26 has warned that projected data-centre growth can push the 2026–2030 budget off course.
Streaming’s grams versus Ireland’s gigawatt-hours
Per-hour streaming numbers are small and contested. The Carbon Trust’s DIMPACT-based white paper, summarised in Fraunhofer FOKUS’s 2024 Green Streaming review, put an average European video-streaming footprint at about 55 grams of CO2e per hour. End devices and household networks often dominate that bottom-up account; data-centre and core-network slices look modest when the grid is already relatively clean and the video is efficiently encoded. Fraunhofer’s point, which every honest piece should steal, is that studies disagree because methods disagree. Comparing a 55-gram hour to a short drive is a parlour game. It does not cancel a national 7,663 GWh line.
The honest Irish sentence is therefore two-scale. Your evening of RTÉ Player or a European streamer is not a coal plant. Ireland’s role as a host of European and global compute is a coal-and-gas-and-wind plant question, because the load is here whether the viewer is in Dublin or Dresden. A German household streaming a title whose bits were fetched from a Dublin hall is in an Irish carbon budget. Country-of-origin rules for catalogues were never written for electrons.
Screen Ireland’s own Decarbonisation Report for Ireland’s Screen Stakeholders already names streaming as a significant Scope 3 concern for the production industry: cloud storage costs, which systems to use, and a global data-centre demand that the report, citing international outlooks, expected to more than double between 2022 and 2026 as storage and AI grew. The same report is careful about AI’s double edge — compression and virtual production might save travel; generative models and always-on inference might erase the saving. Albert calculators and green-production tools measure a shoot. They do not measure the decade of catalogue energy after delivery. StreamSCAPES and related EU work on green-production and green-streaming tools are the research layer trying to join those ledgers.
The Irish policy lever is not a “turn down the bitrate” campaign. It is who gets the next megavolt-ampere, on what renewable additionality, and whether households and heat pumps are crowded out so a European catalogue can be snappier.
What a household can usefully hold in its head
First, residential electricity is not the villain of the 23%. Urban plus rural dwellings together still out-consume data centres in the 2025 CSO split (about 28% versus 23%), but the ten-year story is the wedge: data centres from 5% to 23% while homes’ share fell. Streaming growth is part of that wedge. So are enterprise cloud and training runs that never become a film.
Second, public-service media and European works still sit on the same halls. An Irish drama that policy paid to exist is stored and served like everything else. Decarbonising production without a story about distribution energy is a half-green certificate. Prominence rules that push a title onto a homepage do not add watts by themselves; the underlying capacity might.
Third, AI newsrooms and AI VFX — the next MSMN file and an earlier one — are load-growth stories wearing creative clothes. A 40% VFX tax band that pulls work to Ireland pulls render. A newsroom that uses models for transcription is a rounding error. A platform that uses models to generate infinite cheap video is not.
The CRU glide path will not be visible on a Player menu. It will be visible if new halls open beside new Irish wind — or beside new gas. Denmark’s projected growth is the EU comparison the IIEA already uses. Ireland is early, not unique.
Three tests for 2027
One: Did the next large connection that was announced also name additional Irish renewable megawatts, on a timetable a system operator can audit? If the press release only says “sustainable,” it is a brochure.
Two: Did Screen Ireland and public commissioners start asking for delivery and archive energy the way they already ask for Albert reports on a shoot? Scope 3 that stops at wrap is accounting fiction.
Three: Can a household still electrify a boiler in a constrained Dublin suburb, or did the catalogue win the capacity auction by default?
The unfinished work is to put electrons on the same page as quotas, levies and tax credits. Ireland’s European screen system assumes a cloud. Ireland’s climate statute assumes a budget. Until those documents refer to each other, a 23% line will keep arriving each July as a surprise. European viewers do not need to feel guilty about a 55-gram hour. They should know which country’s carbon budget the hour is sitting on — and that, for a remarkable share of Europe’s bits, the answer is still Ireland.
