Electricity demand from data centres is undermining Ireland’s clean energy progress, according to a new warning from the Climate Change Advisory Council. The council said renewable gains are being cancelled out by rapid growth in power use, leaving the State more exposed to imported fossil fuels and global energy price shocks.
For readers following an Ireland news blog, the report adds to wider concern around infrastructure, energy security and climate delivery.
Ireland breaking news: data centres outpace renewable gains
The watchdog said emissions from the electricity sector fell by about 8% in 2025 compared with 2024. But Ireland still missed targets for the share of electricity demand met by renewable sources.
The main reason was sharp growth in data centre demand. Electricity use across Ireland rose by 2.6% in 2025, well above the 1% annual increase seen across Europe. Demand is now 30.2% higher than in 2015.
- Data centre electricity use has risen 463% since 2015
- It is up 220% since 2018
- Average annual growth in data centre demand has been 23%
- All other customer demand grew by just 0.5% a year on average
What the report means for Ireland news
The council said recent emissions improvements were driven less by clean power expansion and more by higher electricity imports and lower coal use. That raises fresh questions for latest news Ireland coverage focused on resilience, affordability and long-term energy planning.
Chairman Alex White said households will not fully benefit from renewable generation unless Ireland delivers more grid capacity, storage and supporting infrastructure. He also said Storm Eowyn showed the need to make electricity resilience a central part of climate adaptation.
What happens next?
The council is urging the Government to speed up onshore wind, solar and grid reinforcement projects. It also said the Critical Infrastructure Bill should prioritise major electricity upgrades while keeping climate obligations in place.
For anyone tracking Ireland breaking news, the key takeaway is clear: renewable ambition alone is not enough. Ireland must build the grid, storage and clean generation needed to keep up with demand and cut reliance on fossil fuels.
