Accelerating the Transition to a Sustainable Energy System - Accessible Version
Energy is central to a functioning, healthy and thriving society, underpinning a wide range of societal and economic goals. To avoid dangerous climate change, a major energy transition is required globally and in Ireland to urgently reduce GHG emissions through ‘a substantial reduction in overall fossil fuel use, the deployment of low-emission energy sources, switching to alternative energy carriers, and energy efficiency and conservation’ (IPCC, 2022, p28). Despite many plans and strategies in place, Ireland is not on track to meet its climate and energy targets. This report, NESC’s fourth report on the energy transition, examines the energy sector in Ireland using systems thinking tools to identify approaches to accelerate the transition to a sustainable energy system.
