In 2019, renewables accounted for 16.9% of total energy consumption. The share is 0.2% higher in comparison to the previous year, only because of lower total energy consumption.

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.

Energy prices increased in the period 2008-2012. In the same period, the most raised the price of the natural gas industry (almost 53 %), followed by price for natural gases for households by 38%, the price of heating oil, for household electricity, the price of petrol NMB 95, diesel D2, at least has raised the price of electricity for industry, for less than 6%.

Overall, taxes on energy products have alternated between decreasing and increasing over the period 2012-2022 (expressed in constant 2012 prices). With the exception of electricity for typical household consumers, where levies have been increasing over the period 2012-2016, taxation on other energy products has been gradually decreasing. Energy taxes were lower in 2022 compared to 2012. The only exception is the electricity tax for typical industrial consumers, where the direct tax burden increased mainly at the expense of contributions (EE, RES+CHP, CO2 tax).

It is estimated that in 2021, over €396 million in energy subsidies was allocated in Slovenia (or 356 € million when adjusted to constant prices in 2015). Incentives for environmentally harmful energy production from fossil fuels and the use of fossil fuels represented 26% of all energy subsidies in 2021, whereas this share was as high as 51% in 2015. Significant progress is observed in subsidizing production from renewable energy sources, CHP, and energy efficiency measures.

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.

In 2021, taking into account only the production of energy from RES in Slovenia, Slovenia achieved a 24.6% share of RES in gross final energy consumption, which is 4.8 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 increase in the share of RES in 2021 is primarily the result of an increase in the use of RES in the heating and cooling sector. The share in electricity production still lags behind the planned development significantly.

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.

In Slovenia, final users have at their disposal only around 73% of primary energy. In 2015 the rate reached its highest level. The efficiency of electricity and heat production is largely influenced by this share in far.

The year 2022 was a very special year for electricity generation in Slovenia, as due to problems with coal supply, solid fuel generation was the lowest in the period 1992-2022, and the very dry year also had an impact on the very low electricity generation from RES. This led to a record share of nuclear power in electricity generation (42%) and very low total generation (13.4 TWh), the lowest since 1999.
