Slovenia is well on its way to compliance with the 2020 non-ETS target. In 2019 Slovenia's non-ETS greenhouse gas emissions were 12.2% below the 2020 target. In 2019 emissions decreased by 2%. Greenhouse gas (GHG) emissions decreased in sectors: other use, transport sektor and in energy and heat production sector. Other sectors saw an increase, with the highest increase in the industry sector, while in waste sector GHG emissions remained practically unchanged.


Final energy consumption amounted to 4,440 ktoe in 2020 and decreased for the second year in a row, this time by 9.2%. The reduction was mainly caused by the measures for preventing the spread of SARS-CoV-2 virus. There was a reduction in all sectors except households. In the period 2000‒2020, final energy consumption decreased by 2.2% and in 2020 reached the lowest value in the observed period. Most energy, 36%, is consumed in transport, followed by industry, households and other uses. The 2020 target has been achieved; final energy consumption was 13.2% lower than the target value.


Primary energy consumption amounted to 6,334 ktoe in 2020 and decreased for the third year in a row, this time by 5.5%. The decrease was due to the reduction in final energy consumption caused by the measures for preventing the spread of SARS-CoV-2 virus, while the electricity production increased compared to the previous year. The structure of primary energy use was in 2020 continued to be dominated by liquid fuels (29.6%), followed by nuclear energy (26.1%), renewable energy sources (18.6%), solid fuels (16%) and natural gas (11.5%).


In 2020, taking into account only the production of energy from RES in Slovenia, Slovenia achieved a 24.1% share of RES in gross final energy consumption, which is 4.3 percentage points more than in 2005. To achieve a binding 25% national target share of RES under the Directive 2009/28/EC, Slovenia purchased the missing production from RES. The implementation of measures to prevent the spread of the SARS-CoV-2 virus has made a notable contribution to the significant increase in the share of RES in 2020, which has led to a sharp reduction in final energy consumption.
