[EN31] Efficiency of systems of production, transport and distribution of electricity and heat
Driving forces

Key message
Good

In Slovenia, over 70% of the energy supply is available to end users. The share is by far the most affected by the efficiency of electricity and heat production.

In the production of electricity and heat in thermal power plants, less than half of the energy invested was lost in 2021. Compared to the EU-27 countries, Slovenia was in the bottom third of countries.

In 2020, the production of electricity from CHP accounted for just under 7% of the total production in Slovenia.
