An investigation published in late July 2026 revealed that Irish data centres used almost one billion litres of water in the previous year, a total of about 1.7 billion litres over two years. The report highlighted that most of the usage came from two large campuses, that reporting requirements were limited to the biggest facilities, and that the sector remained largely unregulated despite its impact on the national water supply. A follow-up story in early August provided a more detailed breakdown for 2023, identifying Meta’s Clones campus and Equinix’s Dublin site as responsible for more than 954 million litres. While the volume equated to the annual consumption of roughly 20,500 people, the national water utility, Uisce Éireann, described it as less than 0.3% of Ireland’s total water demand and “not a significant demand driver in public water networks.” By ~~contrast, the pharmaceutical industry used over four billion litres in the same period. By~~ late August, concerns expanded beyond water usage to include land zoning and electricity grid strain. Residents in areas such as Naas, County Kildare, have expressed frustration over land being zoned for facilities, including sites owned by Microsoft, without what they perceive as adequate local notification. The sector’s energy footprint is also significant; data centres currently utilize one-fifth of Ireland’s national electricity grid, a figure projected to rise to one-third as more facilities are forecast to be built. ~~Ireland remains a key hub for global artificial intelligence infrastructure due~~ In response to ~~its skilled workforce, strategic location, and low corporate tax rates. As~~ these energy concerns, Ireland has implemented the ~~AI revolution drives global~~ Large Energy User Action Plan (LEAP). This policy mandates that data centres consuming more than 10 MW must generate at least 80% of their energy ~~demand, European~~ demand through new on-site renewable generation and storage. This follows the lifting of a moratorium on new data ~~center capacity~~ centre developments in the Dublin metropolitan area. To support this, the government is ~~forecasted to grow significantly~~ investing 18.9 billion euros into the electrical grid through ~~2035.~~ 2030. However, critics and a KPMG report for the government warn that the remaining 20% of energy requirements may still rely on fossil fuels, such as natural gas, until long-duration storage and low-carbon firm technologies become more widely available.
