Cork has been ranked as the second best county in Ireland for producing wind energy, according to figures released by Wind Energy Ireland (WEI). The WEI statistics also show that wind generation in Ireland was the highest on record for a September month. WEI also said that wind energy provided 35% of the country’s electricity last month, while solar and other renewables provided an additional 7%, for a total renewable share of 42%. Wind power generation in September 2025 totalled around 1,129 gigawatt-hours (GWh). Kerry leads the way as Ireland’s top county for wind energy production (129 GWh), followed by Cork (117 GWh), Galway (95 GWh), Derry (77 GWh), and Mayo (71 GWh). Noel Cunniffe, CEO of Wind Energy Ireland, said wind energy is the number one source of renewable energy in the country. “Renewables provided over 40% of our electricity last month and that figure is set to rise as we build more wind and solar farms. “The more wind energy that we produce here in Ireland, the more we can secure our own supply of clean, affordable electricity and reduce the need to import expensive fossil fuels. “Rather than importing hundreds of millions of euro of gas, Irish wind farms ensure money stays at home, supporting Irish workers and businesses.” Mr Cunniffe added that every time a wind turbine is generating electricity, it is pushing down the wholesale electricity prices, which leads to lower electricity bills for consumers. “Research published in 2025 shows that between 2020 and 2023 renewable energy cut energy bills by an average of €320 per person. “That’s an example of how investing in clean energy can deliver real savings for households and as Ireland grows its renewable energy capacity, those savings will continue to grow. “Ensuring we have the right people, expertise and resources in place to deliver more clean, affordable energy across Ireland.”
