The objective of this study is to conduct a quantitative assessment of the theoretical potential of agricultural biomass in EU countries for energy production. It explores various biomass sources, such as agricultural residues, animal husbandry by-products, and energy crops. Using data, the study examines the potential biomass across different EU countries, emphasizing the disparities due to diverse agricultural practices. The analysis underscores the need for customized biomass strategies in each Member State, tailored to their specific agricultural conditions. The study identifies biomass as a vital energy source for the EU's energy independence and reducing fossil fuel reliance. It also highlights the necessity for future research on improving biomass conversion technologies and policy development for integrating agricultural biomass into the energy framework, considering the unique aspects of each country's agricultural sector.
