Ireland's Datacentres Consume 22% of National Electricity, Adding Hundreds to Household Bills

Datacentres in Ireland consumed 22% of the country's electricity last year—more than all urban homes combined—according to the Central Statistics Office, pushing up household electricity bills by hundreds of euros. The figure far exceeds consumption levels in the US and UK, where datacentres account for only 6% of electricity use, raising concerns about a pattern that could replicate across Europe.

Why it matters: As AI infrastructure scales globally, the hidden energy costs of datacentre expansion are emerging as a critical policy issue that affects consumer bills and grid sustainability across multiple markets.
