Ireland's Data Centres Have More Than Sextupled Power Use Since 2015
The load hit a new high this year, just five points short of what every home in Ireland uses combined.
- Data centres' grid share climbed from 5% in 2015 to 23% in 2025, per CSO data.
- Consumption reached 7,663 gigawatt hours in 2025, up 10% from 6,973 the prior year.
- Urban households used 18% of the grid, rural households just 9%, the same report showed.
Why it matters: Ireland's planners chose to feed servers before homes, and no ballot ever asked permission.
