Electricity in Slovenia in 2023

Global Ranking: #13
77.0% #33 Low-carbon electricity
764.64 watts #39 Generation / person
195.73 gCO2eq/kWh #41 Carbon Intensity

As of data from 2023, Slovenia is harnessing a substantial amount of low-carbon energy for its electricity, with over three-quarters of its consumption coming from this clean, sustainable source. Nuclear and hydropower constitute the majority of this, with each providing over a third of the total electricity generation. Fossil energy, in contrast, accounts for just under a quarter, with coal predominating. Solar and biofuels together make a minor contribution, accounting for little more than 3% of the total mix, while gas-fired power plants chime in with not much more than a small fraction.


To boost low-carbon energy production even further, Slovenia can look beyond its borders for inspiration. Drawing parallels with countries demonstrating successful transitions, Slovenia could study Slovakia and France, who share their reliance on nuclear energy, indicating a clear path for Slovenia in expanding its existing nuclear capabilities. Moreover, wind energy could be another area for Slovenia to explore in its pursuit of increased low-carbon electricity provision. Countries like Denmark, Uruguay and Ireland have made notable strides with this particular energy type, with wind accounting for well over a quarter of their total electricity generation.


Tracing the history of low-carbon electricity in Slovenia reveals a consistently significant role for hydropower and nuclear energy. The early 1990s saw fluctuations in hydro and nuclear generation, with increases in hydro generation in 1991 being offset by declines in nuclear energy the following year. The first decade of the 21st century witnessed a steady uptick in hydroelectric power, with a dip in 2005. The nuclear energy production had its ups and downs, notable was the surge in 2014 only dampened by a subsequent drop in 2015. The 2010s exhibited a similar pattern of fluctuating hydro generation, with 2015 marking a significant drop. In the most recent years leading up to 2023, hydro saw a notable resurgence, offsetting previous declines. Throughout these historical changes, the resilience of Slovenia's low-carbon electricity generation has been underscored, demonstrating its enduring commitment to a green energy future.
