From September 2025 through August 2026, low-carbon sources supplied almost 60% of Czechia’s electricity, while fossil fuels accounted for about 40%. Nuclear was the largest clean electricity source, supplying around 41% of the total. Biofuels and solar each contributed roughly 7%, and hydropower provided about 4%. On the fossil side, coal supplied approximately 34% of electricity and gas another 6%. Czechia therefore already gets more than half its electricity from low-carbon sources, but replacing its substantial fossil-fuel share would help reduce climate-changing emissions and air pollution.

Is Electricity Growing in Czechia?

The latest 2026 figures show a mixed picture for electricity growth. Total electricity consumption stands at about 6,715 kWh per person, roughly 1,816 kWh—or 21%—below the historic record of about 8,532 kWh per person in 2007. This comparison shows that consumption has not regained its previous peak, although it does not establish whether consumption rose or fell over the latest year. Low-carbon electricity generation, meanwhile, reached a new record of about 3,992 kWh per person, slightly above the 2025 record of 3,971 kWh. That small increase is welcome, but much stronger clean electricity growth would help meet future demand from electrification and AI.

Suggestions

Czechia can build on its strong nuclear foundation by expanding existing nuclear capacity and developing additional reactors, alongside faster deployment of solar and wind. Neighboring Slovakia, where nuclear supplies about 66% of electricity, and France, at about 67%, provide relevant examples of nuclear-led low-carbon electricity systems. For solar, nearby Hungary generates around 22% of its electricity from this source, while Germany reaches about 20%, offering useful examples for expanding rooftop and larger-scale installations. Germany also generates almost a third of its electricity from wind, while Austria reaches about 12%. These nearby examples support a strategy combining substantial nuclear generation with growing solar and wind output, backed by grid investment and flexibility.

History

Czechia’s low-carbon electricity history includes several major waves of nuclear expansion. In the late 1980s, annual nuclear generation increased by 3.8 TWh in 1986, 4.6 TWh in 1987 and 1.1 TWh in 1988. Another strong expansion came in the early 2000s, with increases of 1.2 TWh in 2001, 4 TWh in 2002 and 7.1 TWh in 2003, followed by a further 1.3 TWh gain in 2006. During the 2010s, nuclear generation grew by 0.8 TWh in 2010 and 2 TWh in 2012, then recorded substantial gains of 4.2 TWh in 2017 and 1.6 TWh in 2018. Solar also made important contributions, increasing by 1.6 TWh in 2011 and 1.4 TWh in 2024. Most recently, nuclear generation increased by 2.3 TWh in 2025, reinforcing its central role in Czechia’s clean electricity supply.
