This study examined contemporary financial mechanisms and instruments that facilitate investment in renewable energy sectors. The research methodology employed statistical analysis of electricity production and consumption data from renewable sources across the European Union and Ukraine. The findings demonstrated that the European Union has experienced substantial growth in renewable electricity generation, primarily attributable to effective investment attraction strategies. In contrast, Ukraine exhibits inconsistent development patterns in its renewable energy sector. The analysis underscored the correlation between robust financial frameworks and successful renewable energy adoption. While the European Union has implemented cohesive mechanisms yielding demonstrable results, Ukraine’s renewable energy landscape reflects the consequences of less stable financial infrastructure. Total generation in the European Union increased from 750.9 thousand GWh in 2014 to 1,130.2 thousand GWh in 2023, which indicates a stable expansion of the sector. The most promising financial instruments were green bonds, which allow attracting significant capital investments for environmental projects, and energy cooperatives that contribute to the decentralisation of energy and the development of local communities. The mechanisms of financing renewable energy in the agricultural sector of European Union countries, in particular Germany, France, Poland, and the Netherlands, were analysed. The research examined the implementation of renewable energy within the agriculture sector, exemplified by RWE (Germany) and Astarta-Kyiv (Ukraine). It was shown that government subsidies, concessional lending, international investment, and corporate finance mechanisms played an important role in overcoming barriers. Ensuring sustainable financing of renewable energy in Ukraine requires an integrated approach, including active attraction of public, private, and international investment
