In the past twelve months, from August 2024 to July 2025, Slovenia's electricity consumption showcased a predominantly low-carbon footprint. More than half, approximately 66%, of Slovenia's electricity was generated from low-carbon sources. Nuclear power held a significant share, producing about 36%, while hydropower harnessed around 27%. However, fossil energy sources contributed about 19% of the total electricity, with coal providing 15% and gas accounting for a mere 4%. Interestingly, Slovenia relied on net imports for approximately 15% of its total electricity needs, while solar power, albeit growing, provided close to none at 3%.
Is Electricity Growing in Slovenia?
Despite these promising figures for clean energy, Slovenia's overall electricity consumption has not seen growth, which is a cause for concern. The latest data shows an electricity consumption rate of 7,964 kWh per person in 2025, marking a decline from the highest recorded figure of 8,471 kWh per person in 2014, a change of -507 kWh. Likewise, low-carbon electricity generation has also diminished, with the latest generation statistics showing 5,276 kWh per person, down significantly from the 2014 record of 6,440 kWh per person. That's a concerning drop of 1,163 kWh, highlighting a need for strategic interventions to revitalize Slovenia's low-carbon electricity growth.
Suggestions
To bolster Slovenia’s low-carbon electricity generation, a focused expansion of existing nuclear facilities could be highly beneficial. Slovenia can draw inspiration from regions like France and Slovakia, where nuclear power accounts for substantial shares of electricity production, 69% and 64% respectively. Similarly, Slovenia can look to Greece and Portugal for their adoption of solar energy, with solar providing 25% of electricity in Greece. Targeted investments in solar technologies could significantly enhance Slovenia's clean electricity generation. Leveraging successful strategies from these regions can help Slovenia reduce reliance on fossil fuels and address challenges related to climate change and pollution, ultimately leading to a more sustainable energy future.
History
Historically, Slovenia has experienced fluctuations in low-carbon electricity generation. In the early 1990s, nuclear energy underwent a setback with a decrease of 1 TWh in 1992 but saw a recovery by 1994. Hydropower contributed positively with consistent increases, notably in 2004, 2008, and 2023, although certain years like 2011 and 2022 saw drops. Notably, the year 2015 marked declines in both nuclear and hydropower outputs. The data for 2025 indicated a reduction in solar and hydropower outputs by 0.9 TWh and 0.8 TWh respectively, highlighting periods of inconsistency that Slovenia needs to tackle. Addressing these fluctuations through strategic planning and infrastructure investment in nuclear and solar can solidify Slovenia's commitment to expanding low-carbon electricity.
