Slovakia is truly a champion when it comes to low-carbon electricity generation, sourcing more than 86% of its electricity from clean energy. Nuclear power is a major contributor, providing more than 60% of the country's electricity, while hydropower adds another 16%. With fossil fuels making up only around 14% of electricity generation, Slovakia's energy sector stands as a model of sustainability in the region. Not only that, but the country also plays a vital role in reducing regional emissions as a significant net exporter of electricity. The next big challenge for Slovakia will be to electrify its transport, heating, and industrial sectors, which will necessitate a greater capacity for clean electricity to meet rising demand.
Is Electricity Growing in Slovakia?
Despite this impressive reliance on clean electricity, Slovakia is currently experiencing a slower growth rate in its overall electricity consumption, with the latest numbers showing 5,319 kWh/person. This is a decrease from its 2002 peak of 6,030 kWh/person, indicating a reduction of 711 kWh/person. However, it’s encouraging to note the rise in low-carbon electricity generation, which has reached 4,576 kWh/person in 2024, marking a modest but positive growth of 38 kWh/person compared to the record set in 2023. The increase in low-carbon generation is certainly a silver lining and underscores continued commitment to sustainability in Slovakia.
Suggestions
To further increase their low-carbon electricity generation, Slovakia should continue advancing its nuclear capabilities. As a proven producer of vast amounts of low-carbon electricity, nuclear power can help meet increasing future demands with unmatched efficiency. While solar power is currently a minor player in Slovakia's electricity mix, it also offers immense untapped potential. By expanding both nuclear and solar power capacities, Slovakia can secure an even more sustainable energy future, significantly contributing to the global fight against climate change and air pollution, while meeting future demands arising from technological advancements such as AI and electrification across various sectors.
History
In the history of Slovakia's low-carbon electricity generation, there have been notable periods of growth and some less favorable declines. The late 1980s saw nuclear power taking off with significant increments, especially a boost of 2.3 TWh in 1986. Entering the 1990s, hydro energy saw a rise in 1993 by 1.5 TWh. However, nuclear energy faced setbacks throughout the mid-1990s and early 2000s. In 2007 and 2009, significant reductions of 2.7 and 2.6 TWh, respectively, were critical moments highlighting the uncertainty. Fortunately, recent years have shown a rebound, with 2023 witnessing robust growth in both nuclear and hydropower, underscoring the trend toward achieving a more sustainable and reliable low-carbon electricity supply in Slovakia.
