In 2023, the majority of electricity consumption in Czechia was sourced from low-carbon energy types, accounting for roughly 57%. A significant portion of this was provided by nuclear energy, which made up close to 40% of the total energy mix. The use of fossil fuels was significantly lower, but still considerable, at approximately 42%. Coal was the primary fossil fuel in operation, contributing over 37% to the total, while gas formed a smaller percentage at around 5%. The rest of the electricity was generated from other low-carbon energy sources like hydro, solar, and biofuels, each forming less than 10% of the total.
In order to increase its low-carbon energy generation, Czechia could learn from other countries. Already producing a large amount of its electricity through nuclear energy, expanding its existing nuclear infrastructure could be a viable option. Here, France and Slovakia, both generating over 60% of their electricity using nuclear energy, stand as examples Czechia could follow. Additionally, Czechia could also explore the possibilities of wind energy, drawing lessons from countries like Denmark, where wind energy forms nearly 60% of their electricity generation. This dual approach could further improve the country’s transition towards a low-carbon future.
Decades of commitment to low-carbon energies, particularly nuclear, have shaped the energy landscape of Czechia. In the late 1980s, the country saw consistent growth in nuclear-generated electricity, with increases years on year from 1986 till 1988. The early 2000s also saw significant growth in nuclear power, with the largest leap in generation in 2003. However, this decade also witnessed a decline in the generation of hydroelectric power. More recently, despite a small decrease in nuclear generated electricity in 2005 and significant drops in the mid-2010s, the general trend towards increased production resumed towards the end of the decade. The first decade of the 21st century saw the emergence of solar energy, which began contributing to the nation's power supply in 2011. However, despite some fluctuations in the generation of other low-carbon energy sources towards 2023, nuclear power continued to be a major contributor to the Czechia's electricity supply.
