As of 2025, Slovenia relies heavily on low-carbon sources for its electricity, with close to 80% of its electricity being clean. Nearly half of this clean electricity comes from nuclear power, accounting for over 40% of the total. Hydropower contributes almost a third to Slovenia’s electricity generation, showcasing a strong commitment to sustainable electricity sources. However, there is still some reliance on fossil energy, making up about 21% of the total, with coal and gas contributing approximately 14% and 7%, respectively. Solar energy is a minor player in Slovenia, contributing less than 6% to the electricity mix, indicating an opportunity for further growth in low-carbon electricity.

Is Electricity Growing in Slovenia?
When considering the electricity consumption trends in Slovenia, it is concerning to note that the current levels have declined. In 2025, the total electricity consumption stands at 6289 kWh per person, which is significantly lower than the previous peak of 8471 kWh per person in 2014. This represents a drop of more than 2100 kWh per person. Similarly, low-carbon electricity generation has also decreased from its previous high, with a current figure of 4980 kWh per person compared to the 2014 record of 6440 kWh per person—a decline of almost 1500 kWh per person. The reduction in both total and low-carbon electricity consumption poses a challenge and highlights the need for Slovenia to reinvigorate its growth in clean electricity production.
Suggestions
To amplify Slovenia's low-carbon electricity generation, expanding existing nuclear energy facilities is crucial, given that nuclear power already plays a significant role. Learning from countries like France and Ukraine, where nuclear power contributes 70% and 55% to their electricity, respectively, could provide valuable insights. Additionally, investing in solar power offers great potential. Slovenia can draw inspiration from regions like Nevada and Lebanon, which derive over 30% of their electricity from solar power. Integrating lessons from these regions can guide Slovenia to bolster its clean electricity output, making a notable impact in the fight against climate change by reducing dependence on fossil fuels.
History
Reflecting on Slovenia's historical trajectory in low-carbon electricity, the early 1990s saw fluctuations, including a decline in nuclear electricity in 1992. The early 2000s marked a period of rising hydropower, while nuclear output improved in the mid-2000s. Unfortunately, a decline in both hydro and nuclear energy occurred during the mid-2010s, which should concern Slovenia. Despite some increases, recent years showed instability, with hydro levels dropping in 2025 and solar output fluctuating. The growing need for sustainable electricity necessitates a renewed strategic focus on expanding stable and robust energy sources like nuclear and solar, ensuring that Slovenia leverages its historical experiences to steer towards a more resilient and clean energy future.
