The total renewable amount of groundwater in shallow aquifers in Slovenia in the hydrological year 2019 was below the average of the comparative hydrological water balance period 1981-2010.

Energy consumption in transport has been declining slightly in recent years. This is due to combination of lower domestic vehicle consumption as well as lower sales to foreign vehicles. Most of the energy is used in road transport. Consumption of diesel fuel in road transport is increasing.

Water consumption in Slovenia represents a relatively small proportion of the annual gross water outflow from the country. In 2019, the annual WEI+ index was around 3%, and same 3% compared to the periodic average of water availability. The Long-term Annual Average Water Exploitation Index shows a slight decrease, but the trend is not statistically significant.

The quick rate of retreat of the Triglav Glacier, which began in the second half of the 20^thcentury, further accelerated till the beginning of the 21^st century. Due to increasing intensity of ice thinning, outcropping rocks began to emerge in the middle of the glacier, which disintegrated into two parts in 1992. In the last part of the first decade of the 21^st century, the glacier has been retreating at a slower rate. The last major recession of the glacier was registered after the above average hot summer of 2003.

Households in Slovenia consume 21.6% of final energy. In 2019, consumption was the lowest in the observed period from 2000 to 2019, but even higher than the target for 2020. Most energy is used for heating. Among energy products, use of heating oil decreased sharply while the use of natural gas increased.
