Climate change is fundamentally changing the energy system of countries and their regions. Fossil fuel sources are being replaced by renewable energy sources. One of the main renewable resources due to its physical properties and widespread use is biomass. The use of this resource is important for economic progress, solving social problems, maintaining the balance of the environment. The positive impact created by the use of biomass is maximized by business entities operating in the cluster structure. There is a lack of research in the scientific literature to summarize the impact of biomass use on the economy, especially in the form of clusters. The dissertation is designed to fill these gaps and assess the impact of biomass use on regional development and their progress. In order to achieve the determined tasks, a conceptual model of biomass cluster impact evaluation on the economy has been formed, indicating the main directions of the impact of biomass use. A biomass convergence index has been developed to comprehensively assess the impact, bringing together data reflecting the sustainable development of the region. Lithuanian data were used to verify the index, emphasizing the country’s progress in the biomass conversion process. An empirical study has shown that the impact of biomass use is multiplied by the growth of municipal revenues, the reduction of certain social costs, and the more efficient use of local energy resources. At the same time, it correlates with the decline in imported fossil fuels.
