In 2024, Slovenia has made admirable strides in its electricity consumption, becoming heavily reliant on low-carbon energy sources. More than three-quarters of Slovenia's electricity comes from clean energy, with nuclear power contributing more than a third and hydropower adding another third to the mix. Despite this impressive achievement, nearly a quarter of the country's electricity still originates from fossil fuels, which are a major threat to the environment due to their role in climate change and air pollution. Coal is Slovenia's largest fossil electricity source, accounting for just over a fifth of total electricity. Solar power adds a smaller, yet promising share, showing potential for growth, while gas and biofuels contribute only marginally.
To further increase its low-carbon electricity generation, Slovenia could focus on expanding its existing nuclear infrastructure. As a country already benefiting significantly from nuclear power, building upon this foundation could provide a reliable and substantial increase in clean electricity. Looking at other nations for inspiration, Slovenia might consider Slovakia's success; with over 60% of its electricity from nuclear power, Slovakia showcases the potential for nuclear expansion. Additionally, harnessing wind energy, as seen in Denmark, which generates over half of its electricity this way, could diversify Slovenia's low-carbon portfolio. These examples underscore the importance of optimized investments in both nuclear and wind power to meet future electricity needs sustainably.
Tracing Slovenia's history of low-carbon electricity, it's evident that hydropower and nuclear energy have shaped its path. In the early 1990s, hydropower saw significant growth, punctuated by years like 1991, with an increase of 0.7 TWh. Nuclear power also fluctuated, with a notable drop in 1992, followed by a rebound by 1994. The period from the mid-2000s onwards was marked by highs and lows in hydropower, while nuclear energy experienced occasional setbacks, starkly in 2012 and 2021, both seeing declines. Significant increases in hydropower were recorded in recent years, such as in 2008 and 2014. The overall pattern indicates a dynamic energy sector with reliance on these two key sources, signaling the importance of consistency and expansion to ensure a stable and sustainable energy future for Slovenia.
