Solar Energy and CO2 Emissions: CCEMG Estimations for 26 Countries
Abstract Although research establishes that the impact of renewable energy on environmental sustainability is critical in the era of globalization, the individual impact of renewable energy on the environment is often ignored. Therefore, this article examines the long-term relationships and direction of these relationships between solar energy consumption, coal energy consumption, financial globalization, economic growth, and environmental pollution for the period from 2000 to 2019 for 26 countries. The study used a range of econometric techniques that account for the cross-sectional dependence and slope homogeneity observed in the panel. The results of the common correlated effects mean group (CCEMG) estimator showed that solar energy consumption has a negative and significant effect on the level of carbon emissions. In addition, economic growth and coal energy increase carbon emissions. Finally, the results of the panel causality test confirmed the existence of various causal relationships among the variables.
