Rationalization of energy consumption and sustainable development quality: study of the relationship between energy consumption and economic growth (case of Tunisia).

Summary Studying the relationship between energy consumption, economic growth and the environment is crucial in the policy proposal process. Except, the question that arises, what is the use of proposing actions, strategies and policies that are not practiced by the consumer. For that, our reflection was articulated in three axes within this thesis by starting to study the relation between the consumption of energy and the economic growth by taking into account the price of oil, in first axis. Then, we studied this relationship but this time by integrating the environmental side via CO2 emissions to take into consideration the environmental effects due to energy consumption which followed the rhythm imposed by the acceleration of economic growth. Hence, the interest of energy and environmental policies aimed at reducing energy demand and protecting the environment. The citizen as an actor of RSA must have an awareness of SD through several actions such as education and training on the one hand and the provision of information to the public from children to youth to adults. However, the lack of awareness led to a misunderstanding of the action programs and therefore a practical problem. Otherwise, the success of these actions in Tunisia requires an awareness combined with the participation of other actors. For these reasons, the last part was devoted to the study of awareness among students and teachers. According to the results, students and teachers are little (or sometimes not at all) informed about the control and protection of the environment. Therefore, the implementation of training and awareness programs is seen necessary within academic institutions and all educational institutions, and RSA actors in general. Nevertheless, these actors should not act out of obligation but rather they should be convinced of the strategic interest of the country's energy and environmental policies.
