Bulgaria's electricity consumption in 2025 is prominently supported by low-carbon energy sources, which contribute more than 70% of the total electricity mix. Leading this clean energy generation is nuclear power, providing almost 40%. Solar energy is also a significant player, representing nearly a fifth of the electricity consumed. Meanwhile, hydropower and wind energy contribute about 8% and 3%, respectively, to the total share. Fossil sources like coal and gas still account for around 28%, with coal making up the majority. The dominance of low-carbon resources highlights Bulgaria's commitment to a cleaner energy future, but there remains room to push fossil fuel reliance even lower to mitigate climate change and air pollution.

Is Electricity Growing in Bulgaria?
The overall electricity consumption in Bulgaria has seen a decrease compared to its peak back in 2011. In 2025, the electricity usage stands at 5482 kWh per person, a decline of over 1400 kWh from the historic high. On a positive note, low-carbon electricity generation has hit a new record, reaching 3968 kWh per person, an increase from the previous year. While the general decrease in total electricity consumption may highlight efficiency gains or changes in demand, the growth in low-carbon generation is a step in the right direction. A continued increase in clean electricity is essential for Bulgaria to support further electrification and future technological developments.
Suggestions
To boost low-carbon electricity generation, Bulgaria should focus on expanding both its nuclear and solar capacities. Learning from regions like France and Slovakia, where nuclear power comprises around two-thirds of electricity generation, could provide strategic insights for bolstering nuclear infrastructure. Similarly, countries like Lebanon and California have significantly adopted solar energy, with solar contributing about a third to their electricity mixes. Exploring best practices and technological advancements from these countries could accelerate Bulgaria's solar and wind energy potentials, paving the path towards a cleaner and more sustainable energy future.
History
The history of low-carbon electricity in Bulgaria has been marked by significant developments, particularly in nuclear energy. In the early 1980s through the 1990s, Bulgaria saw substantial gains in nuclear power generation, with notable yearly increases. However, there were setbacks, especially in the mid-2000s, but growth continued past those challenges. In 2010, hydropower saw a temporary boost, but its impact has fluctuated since then. The recent boost in solar electricity generation in 2024 adds a hopeful chapter to Bulgaria's clean energy journey. Despite previous declines, particularly in nuclear output, the consistent drive towards expanding clean electricity remains pivotal for Bulgaria's energy landscape.
