Slovakia has a plan to get renewable sources of energy up to 19.2% by 2030.[3]
From 2024, following the completion of two new nuclear reactors, Slovakia will return to being a net exporter of electricity.[4]
Slovnaft is the largestoil refinery inSlovakia.
In 2022 Slovakia sought to reduce its reliance on oil from Russia.
Slovenský plynárenský priemysel (Slovak Gas Industry, SPP) is the main natural gas supplier in Slovakia.
In 2022 Slovakia sought to reduce its reliance on natural gas from Russia, which was supplying 81% in 2020.
In order to lower reliance, a gas pipeline interconnector with neighbouringPoland was completed by August 2022 and put into operation in a bilateral opening ceremony on the 26 August 2022.[5][6]
In 2024, SPP entered into a short-term pilot contract to buynatural gas from Azerbaijan to reduce the impact of the Ukrainian closure of the pipeline for Russian supplies in 2025. Transfer will be by theTrans-Balkan pipeline, or possibly via Russia and theTurkStream pipeline across theBlack Sea, then Turkey, Bulgaria, Serbia and Hungary. The contract could be extended into a longer-term deal.[7]
Two coal power stations were operated in Slovakia until 2024, with the power station at Nováky closing in 2023, and thepower station atVojany ceasing production in spring 2024.[8][9] Slovakia currently does not have thermal powerplants in operation and relies on nuclear power generation and power generation from renewables.[10]
There are five operating reactors in two powerplants.Bohunice Nuclear Power Plant, with two reactors dating from the 1980s, and three reactors atMochovce Nuclear Power Plant), with two from the 1990s and the 3rd being commissioned in January 2023. Total electricity generation from nuclear sources in 2020 was 15.4 TWh. One additional reactor is near completion at Mochovce.[11]

Renewable energy includes wind, solar, biomass and geothermal energy sources.
At the end of 2022,wind power capacity in Slovakia constituted 3 MW, a number that has not changed since 2010. In the National Energy and Climate Plan the Government plans to build 500 MW of wind power by 2030.[12]
In 2023 Slovakia had 840 MW of installed solar power capacity.[13]
Biomass provides around 4% of electricity generation capacity.
There is hydropower potential in theVáh andOrava rivers (before Starý Hrad, and after Kráľoviansky Meander, Oravka tunnel), with hydroelectric powerplants over 30 MW as extremely profitable (for low cost/installed MW).

Emissions ofcarbon dioxide in total, per capita in 2007 were 6.8 tons CO2 compared to EU 27 average 7.9 tons CO2. Emission change 2007/1990 (%) was -35.1%. In Europe in 2007 the Slovak emissions ofcarbon dioxide per capita (6.8 tons CO2) were higher than in Hungary 5.4, Sweden 5.1, Portugal 5.2 or Switzerland 5.6 and lower than in Czech Republic 11.8, Luxembourg 22.4, Finland 12.2, Netherlands 11.1, Germany 9.7 or Ireland 10.1[14]
1990 emissions were 74 Mt CO2 eq. TheKyoto protocol target is reduction of 6 Mt (-8%).[15]
