Prague – The Czech Republic is significantly trailing most EU nations in solar and wind energy utilization. While the European Union saw a 30 percent contribution from solar and wind to electricity generation last year, surpassing fossil fuel sources for the first time, the Czech Republic’s share stood at only 6.6 percent. Recent trends indicate a slowdown in the growth of solar energy, with wind energy facing an even more challenging situation, according to an analysis from the Ember institute obtained by CTK.
Electricity generation from solar energy in the Czech Republic increased to 4.4 terawatt hours (TWh) last year, up from 2.3 TWh in 2020. Although the participation of photovoltaic systems in production has doubled in the past five years, reaching six percent last year, the growth rate has recently diminished, the analysis shows.
“While solar energy generation expanded by roughly 0.8 TWh in 2025, the year-on-year share increase was lower than in 2024. This is concerning because the Czech Republic possesses significant untapped solar potential and is still beneath the EU average for renewable energy usage,” stated Ember analyst Tatiana Mindeková. She warned that without a renewed growth trajectory, the existing advancements might not contribute to a substantial transformation of the energy mix, putting the Czech Republic at risk of lagging behind the EU in energy sector transformation.
The Czech Republic’s performance in wind energy is even more concerning, with its contribution to domestic production stagnating at around one percent, compared to an EU average of nearly 17 percent last year.
The analysis highlights the effectiveness of combining wind and solar energy. “During the low wind conditions in spring 2025, solar energy effectively compensated, keeping the EU’s renewable share stable. However, the Czech Republic lacks this balance, relying solely on photovoltaics while wind energy remains stagnant. Wind energy is crucial for lowering electricity costs,” remarked Jiří Beranovský from the Czech Technical University in Prague (ČVUT). (22 January)
