In Slovenia, almost 74% of the energy supply is available to final users. This share is influenced to by far the greatest extent by the efficiency of electricity and heat generation.

In 2024, 48% of the energy input was lost in electricity and heat generation in thermal power plants and combined heat and power plants. Compared with the EU-27 countries, Slovenia ranked in the bottom half.

In 2025, the amount of incentives for the implementation of measures related to energy efficiency (EE) and renewable energy sources (RES) in non-ETS industry amounted to EUR 1.7 million. This was 53% higher than in the previous year. This amount only takes into account the incentives of the Eco Fund, as other programmes currently do not allow monitoring of the effects related to climate targets for the co-financed projects in industry.

In 2025, the leverage of incentives in the public sector amounted to 32.9 euro cents of subsidy for 1 euro of investment, which was 21 euro cents less than in 2024. The decline was due to the projects supported by the Eco Fund under the calls for co-financing new investments in the construction of highly energy-efficient, nearly zero-energy buildings of general public interest. For these projects, the leverage of incentives was only 13.3 euro cents of subsidy for 1 euro of investment, while they accounted for as much as 73% of the total value of supported investments.

Specific CO₂ emissions from new passenger cars amounted to 127 g CO₂/km in 2024 and decreased to 117 g CO₂/km in 2025. The increase in the share of electric passenger cars contributed significantly to this reduction. Nevertheless, the target value for the 2025–2029 period, set at 93.6 g CO₂/km, has not yet been achieved.

In 2024, average CO₂ emissions from all passenger cars amounted to 157.5 g CO₂/km and changed only marginally compared with 2023. The target value for 2020, set at 152 g CO₂/km, therefore remained unmet.

In 2024, the share of RES in transport, after an increase in 2023, dropped again and amounted to 9,2%. With this, it was 1,6 percentage points behind the non-binding 2024 target from the updated National Energy and Climate Plan (NECP 2024).
