Essays on economic analysis of renewable energies dynamics

Since the 19. century, the economic development of nations has been accompanied by high energy consumption. Today, the energy sector is still largely dominated by fossil fuels (coal, oil, natural gas) which are non-renewable and are resources, and considered as one of the causes of global warming through CO₂ emissions. Thus, several policies and strategies to promote efficiency and energy transition are implemented worldwide through the renewable energies deployment (wind energy, hydroelectricity, solar energy, biomass) in order to satisfy global energy consumption without irreversibly damaging the quality of the environment. Using three main angles of analysis, we focus in this thesis on the question of renewable energies dynamics, particularly in France. First, using a microeconometric model and a database provided by ADEME, we seek to identify what are the determinants of households energy consumption in France and highlight the motivations underlying their transition towards less polluting sources. Then, we focus on the drivers of renewable energies deployment in the French departments using spatial econometric analysis. Finally, we seek to identify the effects of oil price on the stock prices of companies operating in the renewable energy sector using a Markov Switching Garch model. (author)
