In 2022, energy efficient district heating (DH) systems, i.e. systems that meet one of the criteria defined in Article 50 of the Act on Energy Efficiency, produced almost 87% of all heat in DO systems, which is the highest value in the observed period. The total share of heat from renewable energy sources (RES) and waste heat amounted to almost 21% in 2022. It increased by 2 percentage points compared to the previous year, and by 5 percentage points compared to 2016. It was 1.5 percentage point higher than the 2022 indicative target value, set according to the Renewable energy directive.

The trend of decreasing energy consumption in households between 2010 and 2022 indicates a positive attitude of the population towards efficient energy use. However, since 2017, a negative trend has been observed, particularly in households' awareness of their own energy consumption and in their consideration of more efficient use. With three-quarters of households in 2022 rating their energy consumption as medium to very high, a significant potential for reducing energy consumption in this sector is suggested.

The car remains the primary mode of transportation, regardless of the distance or purpose of the trip, while the use of public transport does not show a significant increase. The main barriers to using public transport are poor accessibility, inadequate timetables, a lack of connections, and difficult access. Time inefficiency is also a significant issue. However, there are reasons for optimism, as households are increasingly open to using public transport and car-sharing.

While the declarative attitude of Slovenian households towards the environment and efficient use of energy is improving, the ratio between environmentally aware and unaware households remains unchanged. This is evident from their environmentally oriented behaviour and actual efficiency in energy use. The results of the Slovenian Energy Efficiency Survey – REUS indicate a great potential for reducing final energy consumption in households through the development of environmentally oriented behaviour and positive habits in energy use.

The cumulative final energy savings due to the implementation of energy efficiency (EE) and renewable energy source (RES) measures in the residential sector amounted to 1,980 GWh by 2021, and the cumulative CO₂ emissions reduction was 322 kt. Compared to the previous year, energy savings decreased by 6% and the reduction in CO₂ emissions by 5%. In 2022, according to currently available data, energy savings of 272 GWh were achieved, which is the highest value in the observed 2010-2022 period, and the CO₂ emissions reduction was 60.7 kt.
