Slovenia has impressively managed to secure over 80% of its electricity from low-carbon sources over the past twelve months, spanning from November 2024 to October 2025. This remarkable achievement is largely bolstered by the country's reliance on nuclear and hydropower, which contribute 37.5% and 27.8% respectively to the electricity mix. Additionally, solar power, although not classified as low-carbon here, plays a significant role by contributing 13.32%. However, fossil sources such as coal, which provides 13.4%, and gas at 5.96%, still constitute a little less than a fifth of the total electricity generation. As Slovenia continues to progress, a crucial task lies ahead: the electrification of sectors like transport, heating, and industry, demanding significant growth in clean electricity generation.

Is Electricity Growing in Slovenia?
On analyzing Slovenia's electricity consumption trends, a worrying pattern of decline compared to the past emerges. The latest data shows electricity consumption at 6904 kWh per person, a decrease from a previous record high of 8471 kWh per person in 2014, marking a drop of 1568 kWh per person. Low-carbon electricity generation per capita also experienced a decrease, recorded at 5553 kWh per person, down from 6440 kWh per person in 2014. This downward shift raises significant concerns, especially in the face of increasing electricity needs driven by modernization and technological advancements.
Suggestions
To ramp up its low-carbon electricity supply, Slovenia could enhance its nuclear and solar sectors. Expanding nuclear facilities would capitalize on the existing infrastructure that has proven highly efficient and reliable. Meanwhile, scaling up solar energy not only leverages Slovenia's natural solar resources but also aligns with modern technological trends, offering substantial, sustainable electricity generation. By focusing efforts on these already productive and promising sectors, Slovenia can significantly enhance its electricity output, matching predicted future electricity demands and minimizing reliance on fossil fuels that contribute to climate change and air pollution.
History
The evolution of low-carbon electricity in Slovenia shows a mixed bag of promising growth and challenging years. Starting with a significant 0.7 TWh spike in hydroelectric power in 1991, the country had periods of improved nuclear output such as in 1994 and 2014, both recording 0.7 TWh and 1.1 TWh increases respectively. However, frustrating declines were evident with nuclear reductions in 1992 and 2012, each seeing a drop of 1 TWh and 0.7 TWh respectively. Hydropower also saw variations, with notable increases in 2004, 2008, 2009, and 2018 but confronting reductions in 2011, 2015, 2017, and 2025. Encouragingly, the hydroelectric surge in 2023 and solar's addition in 2024 underscore the resilience and potential of Slovenia's low-carbon journey.
