Renewable electricity from wind turbines and solar farms cut gas consumption and carbon credit expenditure across the island of Ireland by more than €1.5 billion in 2025, new analysis reveals.

Wind accounted for €1.4 billion of the total savings, representing 93 per cent of the reduction, whilst solar contributed €115 million.

The Republic of Ireland captured €1.1 billion in savings, with Northern Ireland accounting for the remaining €426 million, according to the Cutting Carbon, Cutting Bills report commissioned by Wind Energy Ireland and produced by consultancy Baringa.

Renewable availability shielded households and businesses from extreme gas price fluctuations throughout 2025.

February represented the most valuable month, with renewables cutting gas and carbon spending by €225 million during the winter demand peak.

Avoided emissions totalled over 5 million tonnes of carbon dioxide across the island, equivalent to annual energy-related emissions from approximately 1.2 million homes.

Cumulative savings over four years now reach €6.7 billion, which Wind Energy Ireland described as a "staggering" amount that would otherwise have flowed to global fossil fuel suppliers.

Wholesale electricity costs averaged €126.95 per megawatt hour in 2025, but fell to €101.84 on days with highest wind generation and rose to €145.84 when wind output declined.

Noel Cunniffe, chief executive of Wind Energy Ireland, said: "Together, wind and solar are helping to build a true Irish electrostate where we can power ourselves with our own clean, affordable and secure energy."

Ronan Power, chief executive of Solar Ireland, noted solar's unique delivery at utility scale and on rooftops across homes, businesses, schools, farms and community buildings.

"That accessibility allows communities to generate their own clean electricity while reducing reliance on imported gas," Power said.
