Ireland faces a significant challenge in reducing its greenhouse gas emissions. Although there has been solid progress in increasing Ireland’s electricity production from renewable sources, onshore wind development has been the major contributor. The first phase of development in renewable technologies was dominated by onshore wind and in early 2019 we will see the introduction of a new Renewable Energy Support Scheme for electricity (RESS-E). The next phase of development should see more onshore wind and an advance in the development of offshore wind, solar, bioenergy and other emerging technologies. With most of the progress in the electricity sector, there are particular challenges in decarbonising both the transport and heating sectors and Ireland will not meet its 2020 targets on RES-H and RES-T. In addition, the European Union’s Clean Energy Package will drive the transition towards low carbon technologies post 2020. This will further increase the drive towards low carbon forms of energy production and there will be a review by the European Commission every two years post 2020 which will keep the focus on the progress of low carbon energy technologies. The new support scheme for renewable electricity and a renewable heat incentive scheme (RHI) will support further development of the sector. There will also be a renewed focus on sustainable transport, which will include electric vehicles and compressed natural gas vehicles.
