Abstract: Renewable energy innovations are essential for mitigating greenhouse gas emissions and addressing climate change, guaranteeing a more pristine and healthful environment. Moreover, these advancements stimulate economic expansion by establishing novel sectors and employment prospects while improving energy reliability and ecological viability. For the first time, the current study explores how supply chain disruption and digitalization impact renewable energy innovations. Besides, the study also considered the role of control variables, including human capital, globalization, economic growth, and democracy. The study used moment quantile regression as an estimator focused on the G7 economies, with data from 1990 to 2020. The study findings show supply chain disruption's insignificant and adverse effect on renewable energy innovations. Furthermore, digitalization promotes renewable energy innovations across all quantiles. Besides, this study also found the effectiveness of economic growth in promoting renewable energy innovations across all quantiles. On the contrary, globalization consistently hampers renewable energy innovations across all quantiles, while democracy is seen as an effective tool in increasing renewable energy innovations. The study formulates policies based on these findings.
