In 2024, Slovenia showcases a significant commitment to low-carbon electricity, contributing more than 70% to the national grid. Nuclear power plays a crucial role, accounting for roughly a third of the electricity supply. Another vital source is hydropower, which closely matches nuclear with about another third of the total electricity consumption. Slovenia's reliance on fossil fuels is relatively moderate, at almost 23%, with coal being the primary fossil fuel used. Net imports provide a small fraction of the electricity, about 5%, while solar power contributes to a minor extent, forming around 3% of the total electricity share.
To enhance its low-carbon electricity generation, Slovenia should consider expanding its nuclear capacity, already a cornerstone of its clean energy portfolio. Learning from successful examples, such as Slovakia, where nuclear power comprises 60% of electricity generation, could provide practical insights for growth. Additionally, considering the integration of wind power could be beneficial, similar to Lithuania, where wind contributes 34% to their electricity mix. Expanding wind and solar energy resources, inspired by countries like Greece and Estonia where solar contributes over 17%, can further bolster Slovenia’s clean energy portfolio.
Throughout its recent history, Slovenia has demonstrated a strong focus on low-carbon electricity. In the early 1990s, the country faced a slight setback in nuclear generation, which dipped by about 1 TWh in 1992 but later saw positive increments. Notably, hydropower fluctuated over the decades, with significant increases like the 1.1 TWh rise seen in 2004 and a more substantial 1.8 TWh increment in 2023. However, there were periods of decline, notably in 2011 and 2015, pointing to fluctuating water availability or other challenges. These shifts emphasize the importance of continually expanding and balancing various low-carbon energy sources to ensure a stable and sustainable electricity supply.
