The Winds of Havre deal with the industry of the offshore wind energy. This industry will originate on the Norman coast in the years which come. How is born such an industry? What are the actors and the stakes? How the economic and social fabric will be transformed there? What expectations, which hopes and which concerns of such projects create at the inhabitants of Le Havre, Fécamp and Dieppe? What incidences on the environment? The maritime landscape? The documentary "The Winds of Havre" tries to answer these questions and many others by an exercise of prospective on the theme of the energy transition applied to a territory datum: Normandy.
