Ireland’s energy supply and demand is currently undergoing accelerated changes driven by increased climate policy ambitions and by economic and geopolitical trends. The policy responses that followed Russia’s invasion of Ukraine and the resulting increases in energy prices highlighted our dependency on imported fossil fuels and the need to improve our energy security. This further emphasised the urgency of accelerating the transition away from fossil fuels in Ireland and towards using cleaner and more renewable energy sources to support decarbonisation, protect against volatile energy prices and secure Ireland’s future energy supply.
