Ireland data centre expansion sparks debate over energy and environment

Ireland’s rapidly growing data centre sector is facing intense scrutiny regarding its impact on the national electricity grid, climate targets, and energy security. The industry supports cloud computing, artificial intelligence, and the digital economy, but the high demand for electricity and cooling resources has created tension with national infrastructure goals.

Novelist Sally Rooney has emerged as a prominent critic of the sector, describing data centres as a “disaster” due to their “wasteful consumption of electricity.” Rooney previously opposed a proposed facility in Killala, Co Mayo. In response, Ronan Kelly, chief executive of Digital Infrastructure Ireland, labeled the author a “hypocrite,” arguing that her reliance on print publishing also carries a significant carbon footprint.

The debate is further complicated by post-Brexit dynamics, as Ireland’s digital infrastructure remains closely linked to the United Kingdom through telecommunications and energy relationships. Policymakers face the challenge of managing digital growth while balancing the needs of housing, transport, and other essential public services.
