Almost half of households in single-family houses are in favor of heating with a heat pump. The index was 44 on a scale of 0 to 100 in 2022 and has not changed significantly since 2019. The majority of households in single-family houses still consider the use of renewable energy sources to be important. The share of households considering replacing or supplementing heating with a heat pump, as well as those already using it, increased significantly between 2015 and 2017, and then stabilized. The favorability of heat pumps varies between regions.

Households willingness to use photovoltaic systems in single-family homes has increased. The index increased by 7 index points between 2019 and 2022, reaching a value of 36 on a scale from 0 to 100 in 2022. The share of households that already use or intend to use photovoltaics in the near future has increased the most during this period. Despite the positive change, as many as a quarter of households are still hesitant or reluctant to use photovoltaics. There are no differences in willingness to use photovoltaics between regions.

Frequency of groundwater drought is increasing in recent decades in alluvial aquifers. 8 out of 10 years with highest intensity of groundwater drought in period 1981-2024 occurred after year 2000. Groundwater droughts with higher intensity is characteristic for winter while milder groundwater droughts mostly occur at autumn. Groundwater drought intensity is also increasing seasonally with time between June and September when groundwater use is pronounced.

In Slovenia and in other European countries the proportion of vehicle fleet that comply with the latest and most stringent emission standards increased sharply in period 2011-2020. Penetration of new technology is highest for the diesel cars.

Greenhouse gas (GHG) emissions from transport in Slovenia almost tripled between 1986 and 2022. In the EU, GHG emissions from transport also exceed economic growth on average, but significantly less than in Slovenia; in the period 1990-2022, they increased by a quarter in the EU-28. The main source of GHG is mostly road transport, which contributes as much as 99% of all GHG emissions from transport. The majority share of traffic emissions in Slovenia in total GHG emissions and insufficiently effective measures to reduce them hinder Slovenia's efforts to achieve the accepted obligations.
