Slovenia Total Energy Production & Consumption
The country's total consumption has been declining since 2010 (-1.7%/year since 2017 and -0.7%/year before), reaching 6.1 Mtoe in 2025 (same pace at normal climate). In 2025, it dipped by 4%, returning to its 2023 level. Per capita consumption is 2.9 toe (4% higher than the EU average in 2025). Oil accounts for 36% of total energy consumption, primary electricity (nuclear, hydropower, and solar) for 33%, gas for 13%, biomass for 10%, and lignite for 8%.

Slovenia Oil Production & Consumption
Slovenia doesn't produce crude oil. As the country's only refinery ceased operating in 1998, the country imports all its oil products (4.4 Mt in 2025, 4.5 Mt/year on average since 2016). Most of product imports came from Saudi Arabia (27% in 2025), Italy (18%), and Greece (8%).

Slovenia Natural Gas Production & Consumption
Slovenia doesn't produce natural gas and relies on imports to meet its gas consumption, which has been increasing by around 2%/year since 2014 despite two years of decline in 2022 and 2023 in a context of soaring gas prices and voluntary consumption cut. In the context of the EU voluntary target to cut gas consumption between August 2022 and March 2023 by 15% (compared to the average consumption for the past 5 years), Slovenia achieved a 13% cut between 2021 and 2023. Gas consumption rebounded strongly in 2024 (+6%) and 2025 (+14%), reaching 1 bcm.

Slovenia Coal and Lignite Production & Consumption
Only the lignite Velenje mine is still operating due to a contract to supply the Šoštanj power plant. Initially signed until 2054, the mine will close in 2033 at the latest, following the coal phase-out plan published in 2022. The Trbovlje coal mine stopped in 2013.

Slovenia Renewable in % Electricity Production
The revised NECP (2024) aims to reach at least 33% of renewables in final energy consumption by 2030, including at least 55% for power, 45% for heating and cooling, and 26% for transport. It also targets at least 55% of renewable energy in building consumption by 2030, at least 30% of renewables (including waste heat) in industry, and at least 5% of renewable and low-carbon sources in gaseous fuels (1% in liquid fuels). In 2024, renewables covered 25% of final consumption, including 43% for electricity, 34% for heating and cooling, and 2% in transport.

Slovenia GHG emissions and CO2 emissions
The revised NECP (2024) increased the cut in GHG emissions in 2030 to at least 35-45% (compared to 2005) and at least 55% by 2033. More specifically, it aims to cut GHG emissions by 62% in the ETS sector and by at least 28% in non-ETS sectors by 2030 compared to 2005 (-70% in buildings, -1% in transport, -2.8% in agriculture, -65% in waste management, and -40% in industry), and to achieve a sink of at least 146 ktCO2eq in the LULUCF sector by 2030.
