The current state of electricity consumption in Czechia reveals a significant emphasis on low-carbon energy sources, which account for more than half of the electricity generation. Specifically, low-carbon electricity makes up around 59% of Czechia’s electricity mix from August 2024 through July 2025. Nuclear power is the star performer within this category, dominating the low-carbon segment with almost 40%. Other low-carbon sources include solar power, which contributes over 6%, and hydropower, slightly less than 6%. Fossil fuels, despite their negative impacts such as climate change and air pollution, still compose over 40% of the electricity generation, with coal being the largest contributor within fossil fuels at about 35%, followed by gas at nearly 6%. It's impressive how close Czechia is to pivoting entirely towards clean energy, given the substantial share of low-carbon electricity in its current mix.
Is Electricity Growing in Czechia?
When considering electricity growth in Czechia, the trend is disappointing, as there is a clear decline when comparing recent and historical consumption. In 2025, the average electricity consumption per person stands at 6677 kWh, which is a significant drop from the record of 8532 kWh per person set in 2007, reflecting a decrease of 1854 kWh. This reduction suggests challenges in meeting growing electrification demands. Despite this decline in total electricity consumption, the generation of low-carbon electricity has seen a slight yet positive change, setting a new record at 3951 kWh per person, a small increase from the previous high recorded in 2021. Such growth, albeit modest, is promising for the future of clean energy in Czechia.
Suggestions
To enhance low-carbon electricity generation further, Czechia could prioritize the expansion of its proficient nuclear sector, already a substantial contributor to its clean electric mix. Regions like France and Slovakia, where nuclear power comprises 69% and 64% of electricity generation, respectively, serve as exemplary models of how nuclear energy can sustainably supply large portions of clean electricity. Additionally, Czechia could draw inspiration from countries successfully utilizing solar energy. For instance, Lebanon's solar energy contributes 31% and Nevada's solar generation sits at 29% of their respective electricity profiles, illustrating the immense potential of solar as a reliable energy source. By learning from these successful regions, Czechia has the opportunity to build on its existing low-carbon strategies, including nuclear and solar expansion, to potentially minimize its reliance on fossil fuels.
History
Historically, Czechia’s journey towards a more sustainable electricity generation landscape has been heavily influenced by nuclear energy development. In the late 1980s, nuclear capacity saw impressive growth, with substantial increases in electricity generation. Notably, years 1986 to 1988 exhibited remarkable nuclear electricity expansion by over 9.5 TWh. The early 2000s brought another surge in nuclear generation, particularly in 2003, which saw a significant increase, only to experience declines shortly thereafter. The early 2010s marked the incorporation of solar power, adding a fresh dimension to the low-carbon electricity landscape, with a notable rise in 2011. However, recent years have seen fluctuations with some setbacks, such as the decrease in nuclear output in 2025 by 1.2 TWh. It is crucial for Czechia to harness the lessons from its robust nuclear history and recent solar advancements to drive future progress in clean electricity.
