Handling with energy

The indicator “Public Attitude towards Energy Consumption” points to a stagnation in the self-assessment of final energy consumption in households. The share of households that estimated their energy consumption as low or very low was increasing between 2010 and 2019, but then the trend reversed, and by 2025 it had decreased by 6 percentage points, returning to a similar level as in 2010. A similar situation is observed with households considering more efficient energy use.

The indicator “Public Awareness on Energy Efficiency” shows that awareness of energy efficiency is high among Slovenian households, but the motivation for it has been changing significantly. Household decisions on energy efficiency have been increasingly driven by finances in recent years, while the environmental aspect is losing importance as an equivalent factor.

The results of the REUS 2025 survey show that the willingness of Slovenian households to use alternative means of transport is increasing. Despite this, the personal car remains the absolutely dominant form of transport, and its use over shorter distances is even strengthening. The main reason for this is undoubtedly the large gap between users' wishes and the actual quality of public transport. The main reasons for not using public transport remain the same as in the past: poor connections, being too time-consuming, and inadequate schedules.

The REUS 2025 survey reveals that the share of newly registered electric and hybrid vehicles has grown strongly, representing almost a third (32%) of all new vehicle registrations in 2024, which is eight times more than in 2019. However, their share among all passenger vehicles reaches a modest 6%. When purchasing an alternative-powertrain vehicle, households opt for hybrids (26%) much more often than for fully electric models (6%), which is likely a result of more favorable prices and less dependence on charging infrastructure.

Large majority of registered passenger cars are still powered by conventional fuels (gasoline and diesel).  Although the total share of alternative-fuel vehicles tripled in the period from 2019 to 2025, it still remains very small.

The results of the Energy Efficiency Survey of Slovenia (REUS) 2021 show that 61 % of Slovenian households rarely or never use public transport. Depending on the type of settlements, the largest share of households that use public transport live in Ljubljana and Maribor, as well as in the Obalno-kraška region. A good tenth of those households that use public transport, has used public transport in the recent week, while a fifth of households used public transport in the recent month.

The results of the Energy Efficiency Survey of Slovenia - REUS show that the share of Slovenian households that are ready to start using or increase their use of public transport over the next 12 months remains quite small – a trend has not significantly changed during the 2011-2019 period. The data show that almost a tenth of households are ready, while a quarter of households are considering the option, while more than two thirds are not ready to start using or to increase their use of public transport.

The analysis of results of the Energy Efficiency Survey of Slovenia for the public and service sector (REUS JSS 2020) indicates that less than a tenth of organisations from the public sector and less than a fifth of office-based companies from the service sector (e.g. banks, post offices and other administrative and office premises) believe that energy consumption in their business premises is either low or very low.

The large majority of organisations from the public sector and office-based companies (e.g. banks, post offices and other administrative and office premises) believe that increased energy efficiency of business premises is very important. About three quarters of organisations in both sectors think about using the energy more efficiently. For about a third of organisations from both sectors, which think about the efficient energy consumption, its main purpose is to decrease the quantity of energy used in their business premises.

The large majority of organisations from the public and service sector believe that they are ecologically conscious and that they separate waste. The majority of organisations responded that the efficient use of energy in their business premises is important due to both reducing the costs and to protect the environment. Three quarters of companies and two thirds of public administration organisations have stated that they are well familiar with the environmental impact of their business premises.
