Energy statistics, 2022

Domestic energy production down, energy dependency up

Domestic energy production in 2022 was 8% lower and total final energy consumption about the same as in the previous year. For the first time, we are publishing indicators of electricity consumption in households and business entities and data on energy consumption in service activities.

Less than half of the energy demand met with domestic energy resources

Domestic energy production in 2022 was over 131,000 terajoules (TJ) or 8% less than a year earlier. Nuclear energy accounted for the largest share with almost 47%, followed by renewable energy sources (including hydro energy) with 32% and energy from coal with 21%. With domestic energy resources, Slovenia met less than half (48%) of its energy demand, while the remaining amount was imported. Compared to the previous year, energy dependence increased by 5 percentage points.

Petroleum products prevailed in the energy supply

Considering energy import and export, almost 268,000 TJ were available for energy supply last year. In the structure of energy supply petroleum products prevailed with more than 36%, followed by nuclear energy with 23%, energy from renewable sources (including hydro energy) with around 17%, coal with 12% and natural gas with 11%.

The largest share of energy for transport

Final energy consumption in Slovenia in 2022 was just over 201,000 TJ or about the same as a year earlier. Consumption in the transport sector represented the highest share (41%). The second highest consumer was manufacturing and construction with 25%, followed by households with 22%, service activities with 9% and other users with 3%.

Petroleum products represented the highest share in final energy consumption (47%), followed by electricity with 23%, renewable energy with 14%, natural gas with 12%, heat with 3% and solid fuels with 1%.

Most energy in households for space heating

Final energy consumption in households was almost 43,800 TJ or 10% less than a year earlier. Most of the final energy in households was consumed for space heating (61%), followed by lighting and electrical appliances with 17%, water heating with almost 17%, cooking with 4% and space cooling with 1%.

Among energy sources consumed in households, wood fuels prevailed with 34%, followed by electricity with almost 31%, natural gas with almost 10%, extra light heating oil with 9%, district heat with almost 7%, ambient heat (utilized by heat pumps) with almost 6%, liquefied petroleum gas with almost 3% and solar energy with 1%.

New: Indicators of electricity consumption in households and business entities and data on energy consumption in service activities

For the first time, data on indicators of electricity consumption in households and business entities for 2020–2022, for cohesion regions, statistical regions and municipalities, and data on energy consumption in service activities for 2022 have been published in the SiStat Database.

Electricity consumption in households was 1,656 kWh/capita in 2022 or 5% less than a year earlier.

Energy consumption in the service activities (NACE activities G–S) amounted to around 16,000 TJ.

The largest share of energy was consumed in trade activities (25%), followed by accommodation and food service activities (14%), human health and social work activities (13%), education (11%), transportation and storage (10%), information and communication activities (7%), public administration and compulsory social security (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 (61%), followed by natural gas (11%), district heating (11%), extra light fuel oil (7%), wood fuels (5%) and other energy sources (almost 6%).
