In 2024, 83.1% of all heat in district heating (DH) systems was produced in energy-efficient district heating systems, i.e. systems meeting at least one of the criteria defined in Article 50 of the Energy Efficiency Act (ZURE). Compared with 2023, this share decreased by 4.5 percentage points. The combined share of heat from renewable energy sources and waste heat amounted to 20.5% in 2024, which was 0.7 percentage points lower than in the previous year, but 4.8 percentage points higher than in 2016.

From 2012 to 2024, the installed capacity of the systems for the production of electricity from RES has increased by 78,5%. More than three quarters of that increase, 77,2%, was achieved in the last five years. The indicator is currently on a trajectory of achieving the annual indicative values until 2030 set in the National Energy and Climate Plan from 2024 (NECP 2024).

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.

According to the projection based on existing measures, total greenhouse gas (GHG) emissions will remain at a level similar to today's until 2030 and will then begin to decline. Under the projection that includes additional measures, however, emissions will decrease dramatically – by 35% by 2030 and by 88% by 2050. The projections indicate that, with the intensive implementation of measures, it is possible to achieve the targets set for reducing total GHG emissions, as well as emissions from sources not covered by the Emissions Trading System (ETS).

Slovenia has a relatively high level of energy intensity, although it has been declining, particularly rapidly in recent years. Between 2005 and 2023, energy intensity decreased at an average annual rate of 3.2%. In 2024, energy intensity increased for the first time since 2016, rising by 2.1%. In 2024, Slovenia’s energy intensity was 37% higher than the EU-27 average, which is 15 percentage points less than in 2005.
