In Slovenia, over 70% of the energy supply is available to end users. The share is by far the most affected by the efficiency of electricity and heat production.

In the production of electricity and heat in thermal power plants, less than half of the energy invested was lost in 2021. Compared to the EU-27 countries, Slovenia was in the bottom third of countries.

In 2020, the production of electricity from CHP accounted for just under 7% of the total production in Slovenia.

Energy efficiency in transport is improving, but too slowly, as it improved by only 11% in the period 2000-2019. Most of the energy in traffic is consumed in passenger cars, where efficiency has deteriorated.

In households, energy efficiency improved by 33% over the same period, mainly due to an improvement in energy efficiency for heating. Most energy in households is used to heat homes.

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.

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 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.

In the last decade, droughts have been slightly less intense than in the previous decade, and it is worrying that they occur most often during the growing season. Especially in the first trimester, we observe a decrease in the frequency and intensity of hydrological drought. In the period 1961–2020, the year 2003 stands out in terms of drought, which was dry in all quarters of the year. After 2000, the years 2007 and 2011 were more markedly dry.

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 1981-2023 occurred after year 2000. Groundwater droughts with higher intensity is characteristic for winter while milder groundwater droughts mostly occur at the beginning of autumn. Groundwater drought intensity is also increasing seasonally with time between June and September when groundwater use is pronounced.

The frequency of agricultural drought in Slovenia has been increasing in recent decades. In the last twenty years, we have recorded 7 droughts that affected Slovenia at the scale of a natural disaster. Drought is occurring with increasing intensity and in areas and seasons where there have been no problems in the past. An additional risk for agricultural drought are rapidly developing droughts in summer ("flash droughts"), which occur especially during heat waves. Projections show that trend of increasing frequency and intensity of agricultural drought will continue in the future.

Soil drought has a key impact on plant development and consequently on various industries (forestry, agriculture, …) . Indicators of the number of drought days and the duration of drought periods in individual years show an increase especially after 1990. Similarly, the analysis of the impact of the climate change up to 2100 shows that soil water deficits will increase in the future. The number and the duration of the droughts will increase.
