Over the last twelve months, from September 2024 to August 2025, electricity consumption in Czechia has been significantly powered by clean energy sources. Low-carbon electricity, which includes both nuclear energy and other clean types, accounted for almost 60% of the total electricity generation, showcasing Czechia's commitment to reducing carbon emissions. Within this category, nuclear power contributed almost 40%, affirming its role as a crucial component of Czechia’s energy landscape. Fossil fuels, despite their historical dominance and significant drawbacks like climate change and pollution, still made up roughly 40% of electricity production, with coal being the predominant factor. Solar and hydropower together contributed a noticeable share, emphasizing the nation's potential to transition further towards sustainable energy, especially solar, given its rising contribution.
Is Electricity Growing in Czechia?
Examining trends in electricity consumption raises both potential and areas of concern. The latest data shows that in 2025, electricity consumption was about 6713 kWh per person, which is a significant drop from the historical high of 8532 kWh per person in 2007. This decline of 1819 kWh per person indicates stagnation or even regression in overall electricity growth, potentially missed opportunities in industrial and technological development that could have been supported by electricity. However, there is a silver lining in the sphere of low-carbon generation which has reached a new high at 4024 kWh per person, surpassing the previous record set in 2021, showing some positive growth. This increase of 96 kWh per person highlights Czechia's potential to lead in clean electricity generation, particularly with further development of its nuclear capabilities.
Suggestions
To increase low-carbon electricity generation, Czechia should expand its existing nuclear infrastructure, leveraging its already strong performance in nuclear power generation. Learning from successful examples, Czechia can also enhance its solar capacity, taking inspiration from countries like Greece, which successfully generates over one-fourth of its electricity from solar power. The focus should be on what regions like France have achieved with nuclear energy, as it provides nearly 70% of their electricity, demonstrating the immense potential nuclear holds as a reliable and clean source. By taking cues from such examples, Czechia can further solidify its journey towards a greener energy future and reduce dependence on fossil fuels.
History
Reflecting on Czechia's history of low-carbon electricity, nuclear expansion shows significant shifts over the decades. The late 1980s saw notable increases with years like 1986 and 1987 marking substantial growths of 3.8 TWh and 4.6 TWh, respectively. The early 2000s continued this trend, culminating in sizeable growth in nuclear generation in 2003 by 7.1 TWh. However, there were setbacks with reductions in 2005 and again in the mid-2010s, posing challenges that Czechia has since worked to overcome. More recently, solar generation grew by 1.1 TWh in 2024, while biofuels faced a downturn in 2025. Hydropower, despite its reductions earlier, showed resilience with an increase of 1.6 TWh in 2025. Czechia's progression towards clean electricity underscores the need for sustained and strategic development in nuclear and solar resources as pivotal factors in a sustainable and energy-secure future.
