This paper analyses the nexus between renewable and non-renewable energy consumption, financial development, Information and Communication Technology (ICT) diffusion and economic growth, in MENA countries, over the period 1980–2018. We use the novel Cross-Section augmented Autoregressive Distributed Lag (CS-ARDL) estimation technique which accounts for cross-sectional dependence and cross-country heterogeneity issues. We find a positive impact of renewable and non-renewable energy on economic growth, but a negative effect of financial development on economic growth. We also find a positive and statistically significant influence of ICT on Gross Domestic Product (GDP). Renewable energy and ICT diffusion can be considered important determinants of improved economic activity, job creation and better environmental quality. Pairwise Dumitrescu-Hurlin panel causality tests were used to examine the causal relations among the variables. The findings of this study have considerable policy implications for the selected countries.

The study examined the impact of different factors on greenhouse gas (GHG) emissions, by applying the extended STIRPAT model and decoupling analysis for Tunisia for the period 1990–2018. Furthermore, the study utilizes Tapio decoupling model, and the Auto-Regressive Distributed Lag (ARDL) bounds test approach to examine the relationship between the variables of greenhouse gas (GHG) emissions, economic growth, energy consumption, urbanization, innovation, and trade openness. The findings validated an inverted U-shape relationship between GDP and GHG emissions. In addition, we find that the consumption of renewable energy contributes to the reduction of GHG emissions in the long run. The findings call authority for the adaption of the regulatory framework relating to energy management, energy efficiency and the development of renewable energies, as well as to initiate energy market reforms, implement mitigation strategies and encourage investments in clean energies.
