Ljubljana - Slovenia has been gradually improving energy efficiency on the back of a decline in energy intensity, whereas the use of renewables has been increasing at a slow pace, show figures released by the Statistics Office to mark the European Sustainable Energy Week.

Energy intensity dropped by 36% since 2000, with electricity consumption per unit of GDP down by 21% in the same period.

Meanwhile, the share of energy from renewable sources increased by only 6.6 percentage points, going from 18.4% in 2004 to 25% in 2020.

Indicators that most negatively affect the sustainable energy transition include fossil fuels, energy dependency, end use of energy and energy supply.

Between 2008 and 2014, the consumption of petroleum products, natural gas, and solid fuels decreased, then went up for a short while, and down again since 2018.

The trend was similar with the overall supply and end-use of energy.

End-use of energy stood at 187,765 terajoules in 2020, but this was the first year of Covid, when large parts of the economy shut down. In the preceding years the value exceeded 200,000 terajoules.
