The transition to renewable energy technologies (RETs) is crucial for mitigating greenhouse gas emissions and advancing sustainable development. This study investigates the role of financial development (FD) and financial technology (FinTech) in fostering RET deployment across developed and developing economies, while also assessing the moderating effect of FinTech on the FD–RET nexus. Using annual panel data from 2000 to 2022 and applying robust econometric techniques, namely Fully Modified Ordinary Least Squares (FMOLS) and Dynamic Ordinary Least Squares (DOLS), the analysis reveals that FD exerts a significant positive influence on RET deployment in both groups of countries. FinTech directly promotes RET adoption, and in developed economies, it further amplifies the effectiveness of FD through the interaction effect. By contrast, in developing economies, institutional weaknesses and structural barriers constrain FinTech’s ability to reinforce the role of FD. Moreover, real GDP per capita, population growth, and energy prices emerge as additional drivers of RET deployment, although the effect of energy prices remains muted in contexts with fossil fuel subsidies. Overall, the findings highlight the importance of strong financial markets, effective regulatory frameworks, and institutional quality in facilitating clean energy transitions, providing actionable policy insights for accelerating renewable energy adoption worldwide.
