Sally Rooney Confronts Data Center Industry Over Environmental Claims
Ireland’s data center industry has accused writer Sally Rooney of hypocrisy for opposing a proposed facility in Co Mayo, with Digital Infrastructure Ireland chief executive Ronan Kelly citing her reliance on print publishing as a contradiction. Rooney, a best‑selling author, had criticized the project as a “disaster” due to its “wasteful consumption of electricity,” arguing that online ads—powered by data centers—account for 50%–80% of internet data usage. Kelly, speaking to The Journal, calculated that Rooney’s six‑and‑a‑half‑million‑book output generates 15,000 tonnes of carbon emissions, compared to 1,000 tonnes if she had used e‑books exclusively.
Industry Claims Highlight Carbon Footprint Dispute
Kelly’s critique centers on the environmental impact of print books versus digital distribution. He argued that Rooney’s “celebrity status” allows her to “throw criticism” at data centers while benefiting from their infrastructure through e‑book sales. “It’s hypocritical of her when she also distributes her product through data centres,” he told The Journal. The industry group also pointed to the potential for data centers to reduce waste by digitizing physical media, such as VHS cassettes, which “slowly but surely made their way into a landfill.”
University Expert Questions Emissions Comparison
Climate lecturer Paul Deane of University College Cork cautioned against simplistic comparisons between print and digital carbon footprints. “It’s not a straightforward thing doing the numbers,” Deane said, noting that books can be resold multiple times, while e‑books rely on energy‑intensive devices like Kindles. He also highlighted Ireland’s “very polluting power system” compared to other European countries, complicating the environmental calculus.

Data Centers Face Regulatory Hurdles
The Co Mayo project was ultimately rejected after an appeal by retired scientist Colin Doyle. Meanwhile, the Sustainable Energy Authority of Ireland (SEAI) reported that data centers are the “dominant driver” of increased energy demand, with projections of a 10% rise by 2030 despite a needed 15% reduction. Friends of the Earth linked this growth to a €1.4 billion increase in household electricity bills.
Rooney’s Submission Warned of Energy Strain
In her six‑page objection to the Mayo data center, Rooney warned that the facility could “endanger vital resources for hospitals and homes.” Her argument aligned with broader concerns about Ireland’s aging electrical grid, which Kelly said “needs huge upgrades” to support data center expansion. He added that many existing centers are “not fit for purpose for competing in the AI world,” citing “underinvestment” as a barrier to growth.
Industry Pushes for Grid Upgrades
Kelly acknowledged concerns about data center electricity use but blamed Ireland’s grid for limiting capacity. “That prevents us from adding any more cloud‑based data centres,” he said, noting that “pinch‑points” in the system have led to rejections of new projects. The debate reflects a broader tension between climate goals and technological infrastructure, with industry leaders advocating for grid modernization to meet demand.
Unanswered Questions Remain
While Kelly’s emissions calculations have drawn scrutiny, the environmental impact of print versus digital media remains contested. Rooney’s publisher did not respond to requests for comment, leaving her stance unchallenged in official records.
