In 2012, the share of electricity generated from renewable sources in gross electricity consumption was 29.5%, which was 4.1 percentage points below the target value set for 2010. The share increased in comparison to the previous year. This is largely a consequence of higher generation of electricity from renewable sources, particularly due to higher river discharges, as gross electricity consumption was almost the same as a year earlier. In 2012, electricity generation from hydropower represented 90% of total electricity generated from RES, while its share has been in gradual decline.

In recent years, energy taxes have increased mainly due to higher excise duties and taxes. The share of tax in the price of energy in industry has reached the same level as in the price paid by households. In Slovenia, taxes on transport fuels and electricity were below the EU-27 average, while taxes on natural gas in industry and households were above that average, exceeded only by Austria, Italy, Denmark and Sweden. 

In Slovenia, in 2020 the external costs estimate of electricity production ranges from 0.8 - 2.8 € c2000 / kWh. Despite growing environmental awareness, the price of electricity still does not reflect all external costs. Due to incorrect price signals, which are the result of the current situation on the electricity markets, energy sources in Slovenia remain suboptimally used.

Slovenia's import dependence is not decreasing and is about 50%. In 2020 it was exceptionally lower than in previous years due to the epidemiological situation. The most problematic is the import dependency on gaseous fuels, as Slovenia is heavily dependent on fuel imports from Russia.
