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 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 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.
