The dynamic impact of renewable energy consumption on CO2 emissions: A revisited Environmental Kuznets Curve approach

This paper considers a revisited Environmental Kuznets Curve (EKC) hypothesis with potential impact of renewable energy consumption on environmental quality. To this end, paper aims at investigating the validity of the EKC hypothesis employing the dependent variable of CO2 emissions and regressors of GDP, quadratic GDP and renewable energy consumption. This paper, hence, analyzes this revisited EKC hypothesis to observe if (i) there exists an inverted-U shaped relationship between environmental quality (in terms of CO2 emissions), per capita income and per capita income squared and (ii) there exists a negative causality from renewables to CO2 emissions within EKC model
