Over the past year, from July 2023 to June 2024, electricity consumption in Ireland has been distributed between fossil energy and low-carbon energy sources with remarkable closeness. Fossil energy, including gas and coal, accounted for slightly more than 43% of the electricity generation, with natural gas alone comprising almost 40% of the total. Low-carbon energy sources constituted almost 44% of the electricity generation, showcasing Ireland’s commitment to cleaner energy. Wind energy emerged as a leading low-carbon source, accounting for approximately 34% of generation, while other low-carbon sources like net imports, biofuels, and hydropower contributed marginally. Notably, the role of wind power is reflected in its nearly equivalent share to fossil energy, highlighting a crucial transition toward sustainable efforts in Irish electricity generation.
To enhance its low-carbon electricity generation, Ireland can build upon its existing wind energy capabilities. Wind power, already a significant part of Ireland's electricity mix, can be expanded further to reduce dependence on fossil energy. As examples, Denmark has effectively harnessed wind, with nearly 60% of its electricity coming from this source. Ireland can learn from Denmark by investing in technology and infrastructure to maximize wind energy potential. Moreover, examining countries like France, Slovakia, and Switzerland, where nuclear energy has been pivotal in achieving high percentages of low-carbon electricity, Ireland might consider diversifying its clean energy portfolio by weighing nuclear options for a more sustainable mix. Incorporating a balanced mix of effective technology, policy support, and international collaboration could facilitate Ireland’s goal of reducing reliance on fossil sources and amplifying its low-carbon electricity generation.
Historically, Ireland has witnessed a series of developments in low-carbon electricity, particularly led by wind energy. From 2005 onwards, wind energy began to steadily increase, marked by incremental annual growth of roughly 0.5 TWh until 2011 when a marked increase added 1.6 TWh in a single year. The years 2015 and 2020 were notably significant, seeing substantial growths of 1.4 TWh and 2.2 TWh, respectively. However, fluctuations also occurred, such as a decline in 2016 and a drop in 2021, highlighting the variable nature of wind generation and the need for a diversified energy mix. Recently, there has been steady growth with wind, biofuels, and hydro driving low-carbon expansion, although a minor contraction in solar energy was noted this past year. Ireland's consistent advancement in wind energy underscores its potential and the importance of enhancing its contribution to a low-carbon future.
