Over the past 12 months, from November 2024 to October 2025, Czechia's electricity profile has shown a robust inclination towards low-carbon energy sources. Low-carbon sources supplied a bit more than 60% of the electricity, with nuclear power being the dominant contributor at approximately 41%, followed by solar and hydropower at around 7% and 4% respectively. Biofuels account for about 6% of the low-carbon energy mix as well. On the other hand, fossil energy sources still make up about 39% of the country's energy consumption, with coal being the primary fossil contributor, generating nearly 34% of the electricity, and gas contributing about 5%. This clear delineation between clean and fossil energy highlights Czechia's commitment to sustaining and possibly expanding its low-carbon electricity generation.

Is Electricity Growing in Czechia?
Despite this positive shift, the overall electricity consumption in Czechia appears to be in decline. The latest figures, recorded in 2025, show an electricity consumption of 6583 kWh per person, which is significantly lower than the historic high of 8532 kWh per person in 2007—a decline of 1949 kWh per person. However, it is heartening to note a slight improvement in the generation of low-carbon electricity, increasing to 3978 kWh per person from a previous record of 3916 kWh per person set in 2019, marking an encouraging uplift of 62 kWh per person. While this growth in clean electricity is commendable, the overall decline in electricity usage could signal potential industrial or economic challenges that need addressing.
Suggestions
Looking ahead, Czechia has promising opportunities to enhance its clean electricity generation further. Expanding existing nuclear facilities could significantly bolster clean energy output, given the prominent role nuclear power already plays. Learning from other nations with successful low-carbon strategies could be beneficial; for instance, France and Slovakia generate 69% and 67% of their electricity from nuclear, respectively, emphasizing the potential for nuclear as a cornerstone of energy strategy. Additionally, Czechia could harness more solar power, given the success seen in regions like Chile and Hungary, which generate around 24% and 23% of their electricity from solar, respectively. These examples underscore the potential benefits of diversifying and expanding Czechia's low-carbon portfolio, focusing particularly on enhancing solar alongside nuclear.
History
Historically, nuclear power has played a pivotal role in Czechia's electricity generation landscape. The late 1980s witnessed significant expansions in nuclear capacity with annual increases, notably up to 4.6 TWh in 1987. In the early 2000s, further developments occurred, with steady gains and a notable upswing of 7.1 TWh in 2003. However, there have been periods of decline, such as reductions in 2005, 2015, 2016, and 2020, which might have encompassed operational or strategic challenges within the nuclear sector. Solar power, too, has seen gradual increases from 2011 onwards, with notable contributions adding to the low-carbon mix, particularly in recent years with gains of 1.4 TWh and 1.6 TWh in 2024 and 2025 respectively. These historical trends highlight the importance of resilience and strategic foresight in achieving and sustaining future growth in low-carbon electricity generation.
