In 2011 continued the dominance of solid fuels for the production of electricity, which has been available for use in Slovenia, but the share is slowly decreasing. Followed by renewable energy sources to 30% share and of nuclear energy has been produced 24% of electricity. The share of electricity produced from domestic sources was 80% above the target set by the Resolution of the National Energy Program.

In 2011, electricity consumption increased due to some economic growth. In 2000-2011 period, the average consumption growth was 1.7% per annum, which matches the projections in the current NEP.
Compared to the year 2000, the biggest growth was recorded in services sector, followed by the households.

In the production of electricity and heat in thermal power plants and combined heat and power plants 55% of input energy was lost in the year 2010.
Due to a lack of new investments, the efficiency of electricity production and of electricity and heat production is improving too slowly. Compared to the EU-27, Slovenia produced electricity and heat 4 percentage points less efficiently.

Water protection areas represent 17% of the area in Slovenia. Of this 61% is forest, 30% agricultural land, 6% urban land and 3% other surfaces. From agricultural land on the WPA, 49% is grassland, 36% arable land, and permanent crops, agricultural land in afforestation and other agricultural land by 5% each. In the period 2002-2011 have increased the forest areas (1.3%) and urban land (2.3%), and decreased agricultural land (to 1228 ha, or 1.2%).

The main source of environmental (ambient) noise is transport. Road traffic is the most widespread source. Percentage of the population exposed to different noise levels is high. People in urban areas are exposed to the highest levels of noise, because of concentration of population and traffic in the cities. Most worrying is a significant increase in noise at night, because people are most sensitive to noise at that time.
