Renewable energies and energy efficiency adoption’s impact on the environmental quality of MENA countries

Environmental challenges in MENA countries deserve more attention as they are pursuing economic growth and expanding urbanization, and the geographical position of these countries make them more exposed to the outcomes of climate change. In this context, this paper focuses on the proposed solutions for the climate change problem that are renewable energies and the use of fossil fuel effectively in the context of growing urbanization in the MENA region. Indeed, using the GMM estimator for 18 MENA countries during the period 2000-2018, we try to quantify the magnitude of the impact of population, economic prosperity, urbanization, fossil fuels, energy efficiency, and renewable energies, especially solar, wind, and hydropower energies on CO2 emissions. Results allow the environmental Kuznets curve validation and highlight the contribution of energy efficiency in improving the environment. However, the used proportion of renewables in the energy mix does not significantly affect environmental quality. Moreover, solar energy contributes to emissions reduction. While the adopted level of wind and hydropower energy does not allow these countries to improve their environment
