Electricity in Czechia in 2023

Global Ranking: #22
54.8% #65 Low-carbon electricity
52.53 % #25 Electrification
827.38 watts #36 Generation / person
380.60 gCO2eq/kWh #93 Carbon Intensity

In 2023, Czechia's electricity consumption is notable for having more than half of its electricity coming from low-carbon energy sources. Specifically, 54.78% of electricity is generated from low-carbon sources, with nuclear energy being the largest contributor at almost 40% and other sources like biofuels, solar, and hydropower each contributing less than 10%. On the other hand, fossil fuels still account for a significant portion of electricity generation, making up about 45% of the total, with coal alone contributing just over 40% and gas accounting for about 3%. The transition away from coal and towards cleaner energy sources is critical for reducing pollution and combating climate change.


To further increase its low-carbon electricity generation, Czechia could benefit from expanding its existing nuclear capacity, given that nuclear power already provides a substantial share of its clean electricity. Lessons can be learned from France and Slovakia, where nuclear energy contributes about 65% and 62% of their respective electricity. Additionally, the potential for wind energy is significant; countries like Denmark and Uruguay generate 53% and 35% of their electricity from wind. Following such examples, Czechia could invest in both nuclear and wind energy infrastructure to decrease its reliance on fossil fuels and improve its sustainability.


Looking back at the history of low-carbon electricity in Czechia, notable developments occurred in the late 1980s with substantial increases in nuclear power—3.8 TWh in 1986 and 4.6 TWh in 1987. The early 2000s also saw significant growth, with a remarkable 7.1 TWh increase in nuclear power in 2003. However, some declines were noted mid-decade, such as a 1.6 TWh decrease in 2005. More recent years have shown fluctuation; despite setbacks in 2015 and 2016, nuclear expanded by 4.2 TWh in 2017. Solar energy saw a noticeable boost in 2011 with a 1.6 TWh increase, highlighting the potential for diverse low-carbon energy growth. Overall, the focus should be on increasing investments in sustainable technologies to ensure consistent progress in low-carbon electricity generation.
