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 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.

Air pollutant emissions have decreased in the period 2005−2020 to the levels that enable Slovenia achievement of its 2020 targets. But to reach 2030 targets additional decrease is needed. Reduction of emissions contributed to lower impact on ecosystems and human health, as emissions of pollutants that contribute to acidification, ozone precursors and particles, decreased by half compared to 2005.

Slovenia has a fairly high level of energy intensity that is decreasing, especially in the last few years. Average yearly decrease rate in the period 2005-2021 was 2.7 %. Compared to EU-27 Slovenia had 37 % higher intensity in 2020, being 11 % points lower than in 2005.

Passenger car ownership in Slovenia has almost doubled over the last 20 years and has an above-average growth rate. It is closely connected to the use of passenger cars. Since 2008, passenger car ownership in Slovenia has been growing more slowly as a result of the economic recession. Also, motorisation level (expressed in the number of cars per thousand inhabitants) in Slovenia exceeds the average rate of motorisation in the EU as well as in numerous more economically developed EU countries.
