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.

Primary energy consumption amounted to 6,297 ktoe in 2024 and increased by 3.8% compared to the previous year. The increase, which occurred for all fuels, was due to both higher final energy consumption and increased electricity production. Primary energy consumption was 120 ktoe (- 1.9%) lower than the indicative target value for 2024 from the National Energy and Climate Plan from 2024 (NECP 2024). The indicative annual value was thus achieved.

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.

In the period 1961–2024, the mean annual sea level along the Slovenian coast increased. The mean annual sea level at the Koper tide gauge station reached 233 cm in 2024 and was the second highest in the comparative period 1991–2020. The highest annual sea level of 322 cm represented the third highest sea level after 1991, while the lowest annual sea level of 142 cm was the second highest among the lowest recorded sea levels after 1991.
