In 2022, 75% of energy supply in Slovenia was available to end-users, marking the highest level observed in the period. This percentage is largely influenced by the efficiency of electricity and heat production. In thermoelectric power plants and combined heat and power plants, almost half of the input energy was lost in 2022. Compared to the EU-27 countries, Slovenia ranked in the lower third. Electricity production from combined heat and power plants accounted for just over 6% of total production in Slovenia in 2021, with this share declining in recent years.

Foodborne infections remain a significant public health concern in Slovenia and globally. In 2023, the incidence of these infections in Slovenia decreased by 7% compared to 2022, with viral intestinal infections being the most common. Among bacterial pathogens, Campylobacter, Clostridioides difficile, Salmonella, and pathogenic E. coli are predominant. The World Health Organization estimates that at least one in ten people worldwide contracts a foodborne infection each year, representing a substantial burden on public health.

In 2022, drinking water monitoring was carried out for 93.8% of Slovenia's population across 863 supply zones that serve 50 or more people. Large and medium-sized zones, serving more than 500 inhabitants, generally maintain a good water quality. The greatest issues are found in smaller zones (50-500 inhabitants) with a higher percentage of fecally contaminated samples. Chemical contamination was detected in two zones, mainly due to exceeded levels of lead and the pesticide desethyl-atrazine.

In the last twenty years, occurrences of hydrological droughts of surface waters have become more frequent and intense compared to the previous period, and the variability between individual years has also increased. Very dry and very wet years alternate with intermediate periods of hydrologically normal years. The intensity of droughts during the growing season has become more frequent, although, in the last decade, it has been less intense than in the decade before.

Lyme borreliosis (LB) and tick-borne encephalitis (TBE) are the most common vector-borne diseases transmitted by ticks. Between 2014 and 2023, Slovenia reported annually slightly less than 3,000 to over 7,000 cases of LB and an average of 105 TBE cases (the highest in 2020 - 187 cases, the lowest in 2015 and 2021 - 62 cases). Due to climate change, which influences the expansion of tick habitats and extends their activity season, the risk of infection may increase in the future. Increased awareness and individual prevention are key factors in reducing the burden of both diseases.
