Over the past year, from September 2025 to August 2026, Slovakia achieved a remarkable feat by generating more than 85% of its electricity from low-carbon sources. This includes a substantial 66% from nuclear power, demonstrating the country's commitment to clean energy. Additionally, hydropower contributed more than 12%, while biofuels and solar added around 4% and 3%, respectively, to the low-carbon mix. On the other hand, fossil energy sources such as gas, oil, and others collectively accounted for about 14% of the electricity generation. Slovakia's electricity landscape also features its role as a significant net exporter of clean energy, helping neighboring regions toward reducing their emissions. The next vital step for Slovakia is the electrification of key sectors like transport, heating, and industry, which will inevitably increase electricity demand.

Is Electricity Growing in Slovakia?

Despite Slovakia's impressive reliance on low-carbon electricity, the overall electricity consumption has not yet surpassed past highs. The latest data from 2026 shows an electricity consumption of approximately 5100 kWh per person, falling short by about 930 kWh compared to the previous record of 6030 kWh per person set in 2002. Similarly, low-carbon electricity generation, while still dominant, is slightly lower compared to its record in 2002, with just a minor decrease of 20 kWh per person. This stagnation in growth is concerning, especially in light of the global need for expanded clean electricity to meet increasing demands driven by factors like electrification and technological advancements such as AI.

Suggestions

To drive forward the increase in low-carbon electricity generation, Slovakia could benefit significantly from expanding its existing nuclear infrastructure. Given its large contribution to the country's current clean electricity generation, enhancing nuclear capabilities is a logical step to accommodate the anticipated rise in electricity needs. Additionally, further investments in solar energy could complement nuclear energy's reliability by providing sustainable options that harness natural resources. Such strategic expansion would ensure Slovakia remains at the forefront of low-carbon electricity generation, supporting both domestic needs and continued contribution to international energy demands.

History

The history of low-carbon electricity in Slovakia reveals significant strides over the decades. The late 20th century marked notable increases in nuclear power output, particularly with a major boost in the late 1990s and early 2000s. For example, 1986 saw an increase of 2.3 TWh, followed by a series of gains through to 2002. However, there were some reductions in subsequent years due to operational adjustments. Fortunately, recent years hint at a resurgence, with 2023 alone seeing a 2.2 TWh increase in nuclear output, supported by a similar uplift in hydropower. Slovakia's historical patterns signify a robust commitment to boosting low-carbon electricity generation, mirroring recent global trends of advocating for green energy transitions.
