In 2025, Czechia's electricity consumption demonstrates a notable shift toward low-carbon sources. Low-carbon electricity—comprising mainly nuclear, solar, hydro, and biofuels—accounts for approximately 61% of the total electricity generation, with nuclear energy alone contributing over 42%. Solar energy, contributing around 7%, marks a growing segment, while hydropower adds nearly 4% to the low-carbon mix. In contrast, fossil fuels still play a significant role, with coal making up around a third of the total electricity generation and gas adding another 5%. While fossil fuels remain impactful, the strong presence of nuclear power positions Czechia as a country increasingly leaning towards sustainable electricity generation.

Is Electricity Growing in Czechia?
There has been a significant change in electricity consumption patterns in Czechia over the years. As of 2025, the electricity consumption per person is approximately 6567 kWh, which is a notable decrease from the 2007 record of 8532 kWh per person. This reduction of nearly 2000 kWh per person raises concerns about stagnation and the missed opportunities in growth, especially considering the modern needs fueled by digitalization and electrification. However, there's a silver lining—the per person low-carbon electricity generation reached a new peak of 4017 kWh, surpassing the previous record from 2019, indicating a positive yet small step toward sustainable growth.
Suggestions
To further boost low-carbon electricity generation, Czechia could prioritize the expansion of its successful nuclear power infrastructure. Investing in additional capacity would bolster electricity supplies sustainably. Learning from Slovakia, where nuclear power makes up a substantial 66% of electricity generation, Czechia can similarly enhance its clean energy portfolio. Moreover, integrating more solar energy, evidenced by successful implementations in regions like Nevada and Lebanon where solar contributes significantly, can diversify and strengthen its electricity mix. By taking cues from these regions and focusing on clean electricity expansion, Czechia can effectively reduce reliance on fossil fuels and combat climate change and air pollution.
History
The history of low-carbon electricity in Czechia reveals a series of developments and setbacks. In the late 1980s to early 2000s, nuclear power saw significant incremental increases, notably with substantial upsurges in 1987 and from 2002 to 2003. However, post-2005 experienced some declines, notably in 2015 and 2016. Despite this, the upward journey resumed, with notable increments in 2017 and 2018, and a resurgence in 2025. Solar energy also started establishing its presence in the 2010s, culminating in increases both in 2011 and recent years such as 2024 and 2025. This shows a promising trend in diversifying low-carbon sources, although it is crucial to address and halt any unwanted reductions in nuclear capacity to ensure future resilience and sustainability.
