Total revenues from taxes/charges from road, rail and inland water transport in the EU28 amounted to EUR 370 billion in 2016. This is approximately 2.5% of EU28 GDP in 2016. Aviation and maritime revenues are calculated only for a set of selected airports and ports, so it is not possible to determine the share of these revenues in total aviation and maritime tax/charges revenues of transport in the EU28.

The intensity of final energy consumption as well as sectoral intensities in Slovenia have decreased over the period 2005-2022. Most in industry, least in transport. Comparison with the EU-27 shows that Slovenia is worse than the EU-27 average, but the gap has almost halved over the period 2005-2021, with contribution of all sectors except transport.

The intensity of SO2, NOx and CO2 emissions from electricity and heat production in public thermal power plants in 2021 was significantly lower than in 2005, with SO2 emissions intensity 94% lower, NOx  71% lower and CO2 28% lower. Compared to the EU-27 average, the intensity of CO2 emissions in Slovenia in 2021 was higher, NOx emissions slightly lower and SO2 emissions significantly lower.

Over the period 1990-2022, the amount of spent nuclear fuel, the only high-level radioactive waste, increased at an average rate of 5% per year. In the absence of a satisfactory permanent storage solution, there are concerns about the accumulation of this waste.

Over the period 2012-2022, some energy prices increased and some decreased (in constant 2012 prices). Over the same period, the price of electricity for typical industrial consumers increased the most, by 64.4% in real terms, followed by the price of natural gas for industrial consumers, by 5.1%, and the price of fuel oil, by 3.5%. The price of natural gas for typical household consumers decreased the most, by 20.3%, followed by petrol, by 17%, then electricity for households, by 10.7%, and lastly diesel, by 1.7%.
