As of 2024, Bulgaria’s electricity consumption is predominantly sourced from low-carbon energy. Low-carbon sources account for more than two-thirds of the electricity, with nuclear power contributing a significant portion of that at over 40%. Clean energy sources like solar and hydropower add to the mix, providing almost a quarter of the electricity, with solar contributing around 13% and hydropower approximately 8%. Despite the robust share of low-carbon energy, fossil fuels still make up nearly one-third of Bulgaria's electricity, with coal being the most significant fossil energy source. It's clear that while a major portion of Bulgaria's electricity is low-carbon, there remains a reliance on polluting fossil fuels that could be minimized to further reduce its environmental impact.
To further enhance its low-carbon electricity generation, Bulgaria could prioritize the expansion of its nuclear and solar capacities. These sources already provide substantial electricity contributions and increasing their output could significantly reduce fossil fuel dependency. Learning from successful countries is vital; for instance, France and Slovakia provide robust examples with their heavy reliance on nuclear energy, offering insights into achieving high nuclear generation levels. Additionally, Bulgaria could draw inspiration from other regions like Lithuania and Ireland, which have successfully harnessed wind power, diversifying their energy mix. Exploring wind energy further in Bulgaria may bolster the sustainable energy transition, supplemented by Bulgaria’s existing solar success.
Historically, Bulgaria's shift towards low-carbon electricity, particularly nuclear power, has been marked by various expansions and contractions. The early 1980s witnessed significant growth with notable increases in nuclear generation. However, the early 1990s saw unfortunate declines that were critically counterproductive to sustainable electricity development. The latter part of the 20th century and early 21st century was a period of resilience, with Bulgaria working to boost nuclear output amidst occasional setbacks. Meanwhile, fluctuations in hydroelectric power marked the 2010s, with some ups and downs, yet contributing importantly over time. In recent years, such as in 2024, the country has seen a decline in biofuels, cementing Bulgaria's focus on other low-carbon sources like nuclear and solar, underscoring the need for ongoing and enhanced adoption of these environmentally friendly energies going forward.
