Abstract

The aim of this document is to investigate the dynamic relationship between economic growth, renewable energy consumption, energy consumption and CO2 emissions in Tunisia over the period 1990–2015. Unit root tests and co-integration test was used in order to detect the order of stationary and to test the existence long run links between the used variables. We apply the Granger causality test and VECM model to discover the short and long run links between the variables. Results have shown a bidirectional causal relationship between energy use and CO2 emissions. Economic growth affects CO2 emission in the short and long run. While there is a unidirectional links running from energy use to economic growth at short run. The paper shares best practices from Tunisia in terms of efficient use of renewable energy policy enablers, which may be contextualized in other emerging economies in order to keep sustainability and to achieve the green economy.

5 Conclusion and policy implications

The main objective of this study is to investigate the relationship between economic growth, energy use, carbon dioxide emissions and renewable energy consumption in Tunisia using data from 1990 to 2015. Empirically, we tested the order of integration of the series (unit root tests) to ensure that they follow a random walk (only scope of Granger representation theorem). Then we tested the co-integration to determine the existence of a steady state relationship between the variables. Finally, we estimated the error correction model which aims to account in the same equation of a possible deviation from a long-term balance and short-term adjustment process of balance.

Our empirical findings of the Causality test indicate that there is a bidirectional causal relationship between energy use and CO2 emissions and a bidirectional causal relation between CO2 emissions and renewable energy consumption. Moreover, the results indicate that there is a unidirectional relationship running from energy consumption to GDP per capita and from CO2 emissions to renewable energy consumption.

One of the main tasks of energy policy is energy conservation, which means more efficient consumption of energy and a reduction of CO2 emissions through alternative energy options. In addition, the empirical results of this paper provide policymakers a better understanding of energy use–economic growth nexus; energy use-CO2 emissions nexus and renewable energy consumption-economic growth nexus to formulate energy and climate policies in Tunisia. If an increase in economic growth brings about an increase in energy consumption, the externality of energy use will set back economic growth. Under this circumstance, a conservation policy is necessary. In addition, the findings of this study have important policy implications and it shows that this issue still deserves further attention in future research.
