Correction – Energy statistics, 2023
Correction – the data on Energy statistics, 2023 are published again
Due to the receipt of corrected data from the administrative source, statistical data on energy statistics, published with the release on 8 October 2024, are published again. We apologise for any inconvenience and thank you for your understanding.
More than half of the energy demand met with domestic energy sources
Domestic energy production in 2023 was around 141,000 terajoules (TJ) or 7% more than a year earlier. Nuclear energy accounted for the largest share with around 43%, followed by renewable energy sources (including hydro energy) with almost 36% and energy from coal with 21%. With domestic energy sources, Slovenia met more than half (52%) of its energy demand, while the remaining amount was imported. Compared to the previous year, energy dependence decreased by 5 percentage points.
Petroleum products prevailed in the energy supply
Considering energy import and export, around 257,000 TJ were available for energy supply last year. In the structure of energy supply petroleum products prevailed with 34%, followed by nuclear energy with 23%, energy from renewable sources (including hydro energy) with almost 21%, coal with almost 12% and natural gas with 11%.
The largest share of energy again for transport
Final energy consumption in Slovenia in 2023 was around 191,000 TJ or 5% less than a year earlier. Consumption in the transport sector represented the largest share (41%). The second largest consumer was manufacturing and construction with 24%, followed by households with 23%, service activities with almost 10% and other users with 3%.
Petroleum products represented the largest share in final energy consumption (46%), followed by electricity with 23%, renewable energy with 15%, natural gas with 12%, heat with 3% and solid fuels with 1%.
Most energy in households again for space heating
Final energy consumption in households was around 43,500 TJ or 1% less than a year earlier. Most of the final energy in households was consumed for space heating (60%), followed by lighting and electrical appliances with 19%, water heating with almost 17%, cooking with 4% and space cooling with 1%.
Among energy sources consumed in households, wood fuels and electricity prevailed (both with 34%), followed by extra light heating oil with 9%, natural gas with 8%, district heat with over 6%, ambient heat (utilized by heat pumps) with almost 6%, liquefied petroleum gas with 2% and solar energy with 1%.
Electricity prevailed among the energy sources consumed in the service activities
Energy consumption in the service activities (NACE sections of activities G–S) amounted to around 16,000 TJ or 2% less than a year earlier.
The largest share of energy was consumed in trade (26%), followed by accommodation and food service activities (15%), human health and social work activities (13%), education (11%), transportation and storage (9%), information and communication activities (6%), public administration and compulsory social security (also 6%) and professional, scientific and technical activities (5%). Other activities (arts, entertainment and recreation, financial and insurance activities, administrative and support service activities and other service activities) had smaller shares, and in total their share represented almost a tenth of the total energy consumption of the service activities.
In the structure of energy consumption, the largest share of the total consumption was represented by electricity (60%), followed by natural gas (12%), district heating (11%), extra light fuel oil (7%), wood fuels (5%) and other energy sources (almost 6%).
