In 2024, taking into account only the production of energy from RES in Slovenia, Slovenia achieved a 24.6% share of RES in gross final energy consumption. To achieve a binding 25% national target share of RES under the Directive 2009/28/EC, Slovenia purchased the missing production from RES. The share in heating and cooling as well as the share in transport sector, are still significantly lagging behind the planned development.

In 2024, greenhouse gas (GHG) emissions from sources covered by Regulation (EU) 2023/857 increased by 1.8% compared to the previous year. Nevertheless, they remained 0.4% (41 kt CO₂ eq) below the annual target set under the Regulation. The National Energy and Climate Plan from 2024 (NECP 2024) sets a more ambitious 2030 target for reducing non-ETS emissions than the EU Regulation. A comparison with the indicative trajectory towards this target, starting in 2021, shows that emissions were 5 percentage points above the trajectory in 2024.

Primary energy consumption amounted to 6,071 ktoe in 2023 and decreased by 4.1 % compared to the previous year. The decrease was a result of a decrease in the final energy consumption, while electricity production was higher compared to 2022, mainly due to better hydrological conditions. Primary energy consumption was 604 ktoe (- 9%) lower than the indicative target value for 2023 from the from the National Energy and Climate Plan from 2020 (NECP 2020), and 364 ktoe (- 5.6%) lower than the value from the National Energy and Climate Plan from 2024 (NECP 2024).

The frequency of agricultural drought in Slovenia has been increasing in recent decades. Since 2000, natural disaster due to agriculture drought has been declared seven times in Slovenia, the most severe of which occurred in 2003, 2013, 2017 and 2022. Drought of higher intensity keeps occurring more frequently than before and in areas and seasons where it has not been a problem in the past. An additional risk for drought damage in agriculture present rapidly developing droughts in summer (so-called "flash droughts"), which occur during heat waves.

In 2024, net greenhouse gas emissions in the European Union were 2.3% lower than in 2023 and 38.0% lower than in 1990. In Slovenia, greenhouse gas emissions excluding the Land Use, Land-Use Change and Forestry (LULUCF) sector increased by 4.1% compared with 2023. Emissions from non-ETS sectors were 1.8% higher in 2024 than in 2023, but still 12.1% lower than in 2005.
