Water protection areas (WPA) cover 17.4% of Slovenia's territory. The land use structure in water protection areas is dominated by forest (62.1 %), followed by grassland (13.5 %) and arable land (10.5 %). The amount of built-up land in the water protection areas is increasing, while a decrease in arable land and an increase in the share of organically farmed land indicate positive changes in the direction of extensification of land use.

In 2021, the energy reduction in the energy efficiency obligation scheme (energy amounted to 610.4 GWh. A bigger share of the savings, 57%, was achieved through the implementation of energy efficiency (EE) and renewable energy source (RES) measures within the Eco Fund programs. The annual target value was exceeded by a third. For 2022, according to preliminary data, the achieved energy savings are estimated at 700.8 GWh, which is 15% more than the previous year and 53% above the target value.

Primary energy consumption amounted to 6,470 ktoe in 2021 and increased by 2.7 % compared to the previous year. The increase was a result of an increase in the final energy consumption due to the economic recovery after the coronavirus pandemic and a colder year 2021, while the electricity production decreased compared to the previous year. Primary energy consumption was 258 ktoe (3.8%) lower than the indicative target value for 2021 from the currrent National Energy and Climate Plan (NECP), while it slightly lagged behind the annual indicative target from the proposal for the NECP update.

In 2021, taking into account only the production of energy from RES in Slovenia, Slovenia achieved a 24.6% share of RES in gross final energy consumption, which is 4.8 percentage points more than in 2005. To achieve a binding 25% national target share of RES under the Directive 2009/28/EC, Slovenia purchased the missing production from RES. The increase in the share of RES in 2021 is primarily the result of an increase in the use of RES in the heating and cooling sector. The share in electricity production still lags behind the planned development significantly.

Final energy consumption amounted to 4,719 ktoe in 2021 and increased by 7.1 % compared to the previous year. The increase was mainly a result of a economic recovery after the coronavirus pandemic and a colder year 2021. There was an increase in all sectors. Final energy consumption was 177 ktoe (3.6%) lower than the indicative target value for 2021 from the currrent National Energy and Climate Plan (NECP). The annual indicative target from the proposal for the NECP update was also achieved. In the period 2000‒2021, final energy consumption increased by 3.9 %.
