Introduction. The development of renewable energy is one of the key areas for achieving the global energy transition, which necessitates the improvement of mechanisms for its financial support. The increasing capital intensity of renewable energy projects, rising regulatory and market risks, and the acceleration of decarbonization efforts make it increasingly urgent to identify effective financial instruments capable of attracting long-term capital and enhancing the sector’s investment appeal. This is precisely why it is important to study current mechanisms for financing the development of renewable energy based on an analysis of international experience, an assessment of investment instruments, and the identification of promising avenues for raising capital. Methods. The study employed a systematic approach, methods of comparative analysis, generalization, statistical and dynamic analysis, as well as the logical-structural method. Their application made it possible to systematize international mechanisms for financing renewable energy, assess trends in global investments in clean energy, and develop an integrated approach to evaluating the effectiveness of financing renewable energy projects. Results. This study systematizes current international and national mechanisms for financing the development of renewable energy and identifies their advantages, limitations, and practical application characteristics. It analyzes the trends in global investments in clean energy, confirming a growing shift in financial flows toward low-carbon technologies. The feasibility of comprehensively utilizing project-based and blended financing, green bonds, ESG-oriented investments, international credit mechanisms, and alternative sources of capital mobilization has been substantiated. An integrated analytical model for assessing the effectiveness of financing renewable energy projects is proposed, which combines traditional financial instruments, alternative capital-raising models, and AI-driven risk forecasting mechanisms, thereby improving the quality of assessments of projects’ financial sustainability and investment attractiveness. Discussion. Further research should focus on developing economic and mathematical models for optimizing the financing structure of renewable energy projects, integrating digital technologies and artificial intelligence tools into financial risk management systems, and improving mechanisms for attracting international capital in accordance with the principles of sustainable development. Keywords: renewable energy; financial support; investment mechanisms; project financing; green bonds; international financial institutions; blended finance; energy transition; AI-based risk management models.
