The roles of nuclear energy, renewable energy, and economic growth in the abatement of carbon dioxide emissions in the G7 countries

In the current century, the G7 countries have attached more importance to energy security, and have prioritized low-carbon sources which have necessitated the consumption of nuclear and renewable energy resources to achieve a resilient low-carbon system. However, it is still not clear if the sacrifice has paid-off since the environmental quality in the majority of these countries is yet to be significantly improved. As such, this study employs advanced panel data econometric techniques that account for cross-sectional dependence and slope heterogeneity issues to explore the impacts of nuclear and renewable energy use in respect of CO 2 emission mitigation in six of the seven G7 countries. The core objective of this study is to justify whether energy diversification through the…
