Slovakia and energy self-sufficiency? The analyst talks about a difficult path: This is how we deal with renewables
European powers have so far rejected a ban on Russian gas and oil imports. However, the oil embargo, which has been acceded to by the United States and the United Kingdom, is putting pressure on them as well. The situation can change at any time. European leaders have so far promised to impose dependence on Russian raw materials. In the case of gas, it should be up to two thirds this year.

WOOD & Company analyst Eva Sadovska pointed out that the war in Ukraine was increasing pressure on the energy self-sufficiency of Europe, including Slovakia. The move away from Russian fossil fuels and the emphasis on renewable energy sources should therefore be even more pronounced in the future. However, a difficult path awaits us.
Unlike countries such as Sweden, Finland, Latvia and neighboring Austria, we are far behind in the use of renewable energy sources. The share of energy that we obtained from them in 2020 was only 17.3 percent, with wood and wood chips having a significant effect.
At our time, it was still a “very good” number, because our original target was only 14 percent. Compared to the team, in Sweden, for example, they had more than 60 percent renewable energy. Their target was 49 percent.
We cannot be very happy that we have improved compared to 2019, when we had 16.9 percent renewable energy. “The increase in the share was not due to an increase in the amount of energy from renewable sources, but mainly due to a reduction in final energy consumption – especially in transport. This is due to a pandemic that broke out at the end of the first meal in 2020 and continued with a tough lockdown for almost the entire second quarter. ” Sadovská pointed out.
“According to the Statistical Office of the Slovak Republic, the gross production of electricity from renewable sources in Slovakia amounted to 7 279 GWh. Hydropower plants accounted for the largest share, more than two-thirds (67.2 percent). This was followed by wood (including wood waste and other solid waste) with a share of 15.4 percent. Solar photovoltaics accounted for 9.1 percent of RES in electricity production, biogas for seven percent. Gross heat production from RES in 2020 amounted to 6,518 TJ. It accounts for the largest share, up to 82.8 percent of wood (including wood and other solid waste). This was followed by biogas with a share of 11.1 percent. The energy recovery of industrial and municipal waste accounted for 3.1 percent, geothermal heating 2.8 percent, ” stated in the analysis.
In the coming years, Slovakia, as a member of the European Union, will also support increasing the share of energy from renewable sources. “The good news is that our country has the potential to do so. In addition to wood, biogas or energy from the water of the sun and the sun, for example, fully unused geothermal energy may be a suitable option in the coming years. Our country is largely located on the bedrock, which obtains energy from the ground literally wishes, “ I think.
The future in geothermal energy?
In Slovakia, the potential of geothermal energy to implement implemented projects, as well as hydrogeological measurements and surveys across the territory. “Geothermal energy is used in the world to produce electricity, heat and cold, all these uses are applicable in our country. Unlike the sun or wind, it is a source independent of external influences – it is available 24 hours a day without significant fluctuations and is therefore considered one of the most reliable sources in terms of electricity system stability and security of energy supply. “ said geothermal energy expert Michal Masek.
The energy potential of geothermal waters has been set at 5,538 MWt in our country, but today we do not use only about 2 percent of it. According to Mašek, we were able to supply tens of thousands of households with ecological heat and electricity with greater use of geothermal energy. In Slovakia, we currently have 4 localities where heat is produced from geothermal energy for the purposes of central heat supply – Sereď, Galanta, Veľký Meder and Šaľa. Others are still in the phase or preparation.
