In the last decade (2012–2021), on average around 135,000 tons of hazardous waste was generated annually in Slovenia. This waste accounted for 1% to 3% of all generated waste in Slovenia. Since they contain substances harmful to the environment and health, they must be collected, recovered or disposed of separately from other waste.

In the last decade (2012–2021) each resident of Slovenia annually discards on average around 3.5 kg of hazardous municipal waste, of which the majority in waste electrical and electronic equipment (63%).

Both the residents of the EU-27 countries and the residents of Slovenia are only partially aware of the problem of increasing transport and its consequences for the environment and health. Public awareness of the impact of transport on the environment is still relatively low, although the differences between European countries are considerable. People's awareness of the environmental problems of transport does not automatically lead to changing their travel habits, even though this would contribute to their better health.

Electricity consumption in households is increasing, especially in the last two years, and in 2021 it amounted to 3,803 GWh. The share of households equipped with goods that require electricity for their operation is also increasing. For example dishwasher, tumble dryer, mobile phone, microwave oven, personal computer as well as heat pump and air conditioner.

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.
