Global GridCzechia's energy mix and electricity
🇨🇿 In 2025, Czechia generated 75.5 TWh of electricity. The largest source was nuclear at 42%, followed by coal (35%) and bioenergy (8%). In total, 59% came from low-carbon sources (nuclear and renewables) and 41% from fossil fuels.
On average, each kilowatt hour produced about 401 grams of carbon dioxide (CO₂), below the world average of 458 grams in 2025. That makes Czechia the 78th cleanest of 158 countries that generate at least 1 TWh a year.
Electricity demand was 68.1 TWh. Czechia exported 7.43 TWh more electricity than it imported.
Since 2000, electricity generation has stayed about the same, from 72.9 TWh. The low-carbon share went from 22% to 59%. The biggest rise was in nuclear, from 19% to 42% of generation. The biggest fall was in coal, from 72% to 35%. Carbon intensity fell from 767 to 401 grams per kWh.

Primary energy, with nuclear and renewable electricity counted as the fuel a power station would need to make it (the "substitution method"). Here "other renewables" is the Energy Institute's "geothermal, biomass and other" power generation, and biofuels are liquid fuels such as ethanol and biodiesel.

Energy security score
Strong. Czechia ranks 44th of 158 countries and 14th of 39 in Europe. The score shows how well a country could keep electricity affordable and on if fuel supplies were disrupted.
| Measure | Score |
|---|---|
| Produces its own energy In 2024, Czechia produced energy equal to 53% of all the energy it used (100% or more scores full marks). | 53 |
| Variety of power sources How evenly generation is spread across nine sources. The largest, nuclear, made 42%. | 77 |
| Little reliance on imported power Czechia exported more electricity than it imported, so it scores full marks. | 100 |
| Low-carbon power Nuclear and renewables made 59% of generation. | 59 |
| Low gas and oil use Gas and oil made 5.6% of generation; the score is 100 minus that share. | 94 |
The five measures are weighted 30%, 20%, 20%, 15% and 15%. How the score works.
Oil and gas pipelines
