The vast majority of registered personal vehicles are still powered by conventional fuels (petrol and diesel). The proportion of vehicles with alternative propulsion systems has doubled from 2019 to 2022, yet it remains very small.

Although a quarter of the newly registered personal cars in Slovenia are electric or hybrid, their share among all personal vehicles is only around 3%. This is due to the fact that households rarely decide to purchase new cars, resulting in a high average age of cars over 10 years, and it will take a long time for our vehicle fleet to become less energy-intensive. Slovenia ranks in the bottom quarter of European countries by the share of first registrations of new personal electric vehicles.

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.

Final energy consumption in buildings amounted to 1,600 ktoe in 2021 and was lagging behind the indicative annual target from the National Energy and Climate Plan (NECP). Compared to the previous year, it increased by 4%, and compared to 2005, it decreased by 17%. Greenhouse gas (GHG) emissions in buildings amounted to 1,021 kt CO₂ eq. in 2021, thus the indicative annual target from NECP was achieved.
