This study evaluates the impact of energy consumption on environmental sustainability and verifies the existence of the Environmental Kuznets Curve. The findings reveal that non-renewable energy aggravates environmental deterioration, while renewable energy helps improve environmental quality. Additionally, population density, financial development, and trade share also contribute to environmental deterioration.
The current research evaluated the role of non-renewable and renewable energy consumption in environmental sustainability following the N-shaped Environmental Kuznets Curve framework controlling financial develop-ment, population density, and composite trade share. Unlike previous studies, this research used six indices to depict environmental deterioration and environmental quality. More precisely, pressures on nature, ecological footprints, environmental vulnerability, and adjusted net saving are employed to represent environmental deterioration, while environmental performances and environmental sustainability are adopted to proxy envi-ronmental quality. The Dynamic Seemingly Unrelated Regression Equations were used on panel data from 1994 to 2019 in the selected Organization of the Petroleum Exporting Countries. The findings revealed the N-shaped linkage between per capita income and environmental deterioration indicators, such as ecological footprints, adjusted net saving, pressures on nature, and environmental vulnerability. Regarding the linkage between environmental quality indicators, including environmental performances and environmental sustainability, and per capita income, an inverted N-shaped Environmental Kuznets Curve is verified. Considering all six environ-mental indicators, non-renewable energy tends to deteriorate the environment, while the use of renewable en-ergy promotes environmental quality. Moreover, population density, financial development, and composite trade share raise environmental deterioration. The results are vital for achieving a green economy with better envi-ronmental quality.
