Slovenia has met 22% of its energy needs from renewable energy sources. In the past ten years the share of renewables increased by 6 percentage points. The target that Slovenia should achieve by 2020 is 25% of energy from renewable sources in gross final energy consumption.
The share of renewable sources increased the most in heating and cooling; from 14 percentage points in 2005 to 34% in 2016.
Wood is the most renewable energy source in Slovenia. Most wood is used in households, especially for space and water heating. Wood is followed by hydro energy and other renewable energy sources (liquid biofuels, biogas, geothermal, solar and wind energy). These sources represent smaller shares, but their use is growing significantly.
The plan is to cover its EU renewable energy obligations by 2020 mainly with hydro power. A series of five hydropower plants on the lower reaches of the Sava river are under construction and will be finished by 2018. It is anticipated that they shall meet 6% of the nation’s energy needs. The next big hydro power project, a chain of ten hydro power plants is expected to be built on the middle of the Sava river. Expected benefits include increasing the production of E-RES up to 1,029 GWh, an increase in installed capacity of 338 MW. Planned investment is worth 1,588 billion EUR and the expected date of the completed construction of 10 hydro power plants is approximately in the year 2030.
Beside hydro power, the best prospects are in biogas and solar power energy. Share of solar power and biogas plants in renewable energy has been increasing in the last years. On the other hand wind energy production capacities are very low and there are only two big turbines in Slovenia with the total capacity of 3.2 MW. Technical potential for wind energy in Slovenia is about 600 MW.
