The indicator shows the consumption of renewable energy sources, including energy consumption from the sun, biomass (wood, biogas, biofuels) and waste, geothermal energy, water and wind, in final energy consumption.

The gross final energy consumption represents an energy product supplied for energy purposes in industry, transport, households, the service sector, including the public sector, agriculture, forestry and fishery, including the electricity and heat consumed by an energy sector for the electricity and heat production and losses of electricity and heat in distribution and transfer.

The share of RES in gross final energy consumption in 2008 amounted to 14.3 %. In comparison with the previous year, it decreased by 0.7 percentage points, and with regard to 2005 by 0.9 %. Slovenia was 10.7 percentage points away from the objective, which means that, in order to achieve the objective, it would have to increase the share in 12 years by 0.9 percentage points every year.

Figure 1 shows the share of RES in gross final energy consumption, calculated from the data of the Statistical Office of the Republic of Slovenia (SORS) and the EUROSTAT data. The difference for 2005 amounts to 0.8 percentage points. The reasons for such a difference are:
• The final energy consumption by EUROSTAT amounts to 4892 ktoe, and by SORS to 4942 ktoe. If we analyse this difference and consider that EUROSTAT does not consider the consumption of diesel fuel of tractors in agriculture and SORS in transport, we can come to the conclusion that the majority of the difference lies in the differences of final consumption of natural gas in industry, which is most likely a result of the use of different calorific values – the EUROSTAT calorific value (net calorific value) and SORS combustion heat (gross calorific value).
• Normalisation factors for electricity production in hydroelectric power plants are different (EUROSTAT 1990–2004, IJS 1996–2007). Since the water stage of rivers is decreasing, the trends in the 15-year period represent a decrease of the normalisation factor.

The decrease of the share in 2008 is a consequence of the higher growth of gross final energy consumption in comparison with final consumption from RES (Figure 2). The gross final energy consumption in 2008 increased by more than 7 %, while the final consumption from RES by more than 2 %. In the period 2002–2008, the gross final consumption also increased on average by 2.4 % faster than the final consumption from RES, which increased by 1.5 % annually.

The gross final energy consumption is composed of the final consumption in industry, transport, households and other consumption, which is presented in detail in the indicator EN10 – Final energy consumption by sector and consumption of power plants, consumption in the energy sector and losses in heat and electricity transfer. The final energy consumption contributed 96 % to gross consumption in 2008. In 2008, it amounted to 5549 ktoe.

Gross consumption from RES in 2008 amounted to 796 ktoe. The majority of RES were used for heat and cooling production (52 %), followed by electricity production (46 %) and transport (2 %). In the consumption of RES in electricity production, electricity production in hydroelectric power plants was normalised, which decreased the impact of river stages on the annual fluctuations in an individual year to a minimum. In normalisation, the capacity of hydroelectric power plants in an individual year was multiplied by the average number of operating hours in the 15-year period. This is also the source of the difference in data on gross consumption from RES and consumption from RES in the EN18 indicator – Renewable Energy Sources.

In accordance with Directive 2009/285/EC, Slovenia must, by 30 June 2010, prepare an Action plan for renewable energy to guarantee the attainment of the objective. The plan must define the sectoral objectives for the share of RES in transport (at least 10 %), electricity production, heat and cold production and, naturally, measures for the attainment of such objectives. The preparation of the plan is already in progress, parallel with the preparation of the new National Energy Programme.

Considering that the action plan will specify sectoral objectives, it is reasonable to analyse the current situation of the share of RES by sectors. The share of RES in heat and cooling production amounted to 19.3 %; in comparison with the previous year, it decreased by 0.9 percentage points. The share of RES in electricity production was 28.8 %; in comparison with the previous year, it increased by 2.3 percentage points. The share of RES in transport amounted to 0.8 %, in comparison with 2007, it increased by 0.1 of a percentage point (Figure 3).
