Ireland’s energy usage and CO2 emissions rose by 5% in 2015.
The figures published by the Sustainable Energy Authority of Ireland (SEAI) also state GDP increased by 8%, signalling an ongoing link between economic growth and fossil fuel use.
The use of renewables went up by 13.4% but was offset by a higher use of coal and peat and a reduction in total electricity imports, resulting in a 2.3% rise in overall emissions.
Dr Eimear Cotter, SEAI Head of Low Carbon Technologies said: “These figures show the complexity of our energy system and the interplay of economic growth, renewable energy deployment and fossil fuel prices.
“Progress made in renewable energy deployment could be easily undone if we fail to decouple energy use from economic growth and accelerate the move away from fossil fuels, in particular high emissions-intensive fuels such as coal and peat.”
Yesterday it was revealed Scotland beat its emissions target six years early.
