Reimagining energy futures: the role of nuclear power, green growth, and government effectiveness in sustainability

Abstract This study explores how nuclear power can shape the future of energy systems in the United States, with a focus on green growth, energy efficiency, and government effectiveness. The main goal is to examine how factors like load capacity factor (LCF), green growth (GRG), nuclear energy consumption (NEC), government effectiveness (GVE), and environmental policy stringency (EPST) contribute to sustainable energy outcomes. Using a unique empirical approach that combines Multi-variate Quantile-on-Quantile Regression (M-QQR) with Quantile-on-Quantile Granger Causality (QQGC) tests, this research uncovers complex, nonlinear interactions and causal relationships between these elements. The results show that green growth positively influences LCF, especially in areas with significant renewable energy investments. Additionally, effective government actions and stringent environmental policies are crucial for improving energy systems and boosting efficiency. Nuclear energy consumption plays a key role in enhancing energy reliability and performance. The study concludes with policy recommendations that stress the importance of strengthening government effectiveness and implementing stricter environmental policies to increase LCF, which is vital for creating a more sustainable and resilient energy infrastructure in the U.S.
