The frequency and intensity of groundwater droughts in alluvial aquifers have been increasing in recent decades. 8 out of 10 driest years in the 1981-2025 period occurred after year 2000. Higher intensity droughts generally occur in winter while milder droughts are characteristics of autumn. However, in the Primorska region and Ljubljana basin, extreme droughts predominately occur in summer. An increasing trend in extreme drought intensity is evident between June and September, coinciding with periods of peak water demand.

The preference index for energy-saving household appliances among Slovenian households is a high 83 (on a scale from 0 to 100), which clearly shows the market is in a mature phase and its potential has been largely realized. This is also reflected in the consumer segmentation: on one hand, we find that nearly a quarter are " Energetic Catalysts" who have already fully upgraded their appliances, while on the other, there is only a smaller group of "Passive" and "Restrained" consumers.

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 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 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.
