Bulgaria’s Renewable Heating Dip: A Sign of EU-Wide Challenges or a Local Anomaly?
Recent Eurostat data paints a mixed picture for renewable energy in Europe. While the EU as a whole is making strides towards its heating and cooling renewable energy targets, Bulgaria stands out as one of the few member states experiencing a decline. In 2024, Bulgaria’s share of renewable energy for heating and cooling fell by 1.9 percentage points – a concerning trend that warrants closer examination.
The EU’s Renewable Heating Progress: A Decade of Growth
Across the European Union, the adoption of renewable energy sources for heating and cooling is on the rise. In 2024, it reached a record 26.7%, up from 11.7% in 2004. This growth, though slightly slower than the long-term average of 0.75 percentage points annually, is largely fueled by increased use of biomass and heat pumps. The EU is legally obligated, under Directive (EU) 2023/2413, to increase its annual share of renewables in heating and cooling by at least 0.8 percentage points until 2025, and 1.1 percentage points from 2026 onwards. So far, the EU average annual growth is at 0.93 points for the period 2021-2024.
This progress isn’t uniform. Sweden, Finland, and Latvia are leading the charge, boasting renewable heating and cooling shares of 67.8%, 62.6%, and 61.8% respectively. These nations have long-standing commitments to sustainability and favorable conditions for renewable energy deployment, such as abundant forestry resources (biomass) and geothermal potential.
Why is Bulgaria Bucking the Trend?
Bulgaria’s 1.9% drop, alongside significant declines in Estonia (-11.1%) and Greece (-2.9%), raises questions about the specific challenges facing these countries. Several factors could be at play. A reliance on older, less efficient heating systems, economic constraints hindering investment in renewable infrastructure, and potentially, policy implementation issues could all contribute. It’s also possible that temporary factors, like unusually mild winters reducing heating demand, might skew the data, but a sustained decline is a clear warning sign.
Pro Tip: When evaluating renewable energy data, always consider the specific context of each country. Geographic location, economic conditions, and existing energy infrastructure all play a crucial role.
The Rise of Heat Pumps and Biomass: Key Drivers of Change
The EU’s success in increasing renewable heating is heavily reliant on two technologies: heat pumps and biomass. Heat pumps, which transfer heat from the environment rather than generating it, are becoming increasingly popular due to their efficiency and ability to run on electricity from renewable sources. Countries like Norway, with its high proportion of hydroelectric power, are seeing particularly rapid heat pump adoption. The International Energy Agency (IEA) predicts continued strong growth in the heat pump market globally.
Biomass, derived from organic matter like wood and agricultural waste, remains a significant contributor, particularly in countries with substantial forestry resources. However, the sustainability of biomass is increasingly scrutinized, with concerns about deforestation and air pollution. Sustainable sourcing and advanced combustion technologies are crucial to mitigating these risks.
Looking Ahead: Future Trends in Renewable Heating
Several trends are poised to shape the future of renewable heating in Europe:
- Increased Electrification: A shift towards electric heating, powered by renewable electricity, is expected to accelerate. This includes heat pumps, electric boilers, and direct electric heating.
- District Heating Networks: Expanding district heating networks, utilizing renewable sources like geothermal and biomass, can provide efficient and sustainable heating to entire communities. Euroheat & Power advocates for the expansion of district heating across Europe.
- Green Hydrogen: Hydrogen produced from renewable electricity (green hydrogen) is emerging as a potential fuel for heating, particularly in industrial processes and for high-temperature applications.
- Policy Support and Incentives: Continued government support, through subsidies, tax breaks, and regulations, will be essential to drive further adoption of renewable heating technologies.
Did you know? The EU’s ‘Fit for 55’ package aims to reduce greenhouse gas emissions by at least 55% by 2030, with a significant focus on decarbonizing the heating and cooling sector.

FAQ: Renewable Heating in Europe
- What is the EU’s target for renewable energy in heating and cooling? The EU aims to increase the average annual share of renewable energy in heating and cooling by at least 0.8 percentage points for 2021–2025 and by at least 1.1 points for 2026–2030.
- What are the main renewable energy sources for heating? Biomass and heat pumps are currently the dominant renewable heating sources, but solar thermal and geothermal are also gaining traction.
- Why is Bulgaria’s renewable heating share declining? Potential factors include reliance on older heating systems, economic constraints, and policy implementation challenges.
- Is biomass always sustainable? Not necessarily. Sustainable sourcing and advanced combustion technologies are crucial to ensure biomass doesn’t contribute to deforestation or air pollution.
