[en] Whereas the wind sector displays a particularly strong growth, and the PACA region possesses a lot of natural resources and assets regarding wind energy, this study aims at providing information and other elements to be used for a better definition of future wind energy projects in this region. Based on a regional wind energy atlas, it aims at providing technical, environmental, and regulatory constraints, as well as landscape studies, and thus a relevant decision-making tool for the development of wind energy in PACA. It is based on an inventory, classification and cartography of environmental, technical and regulatory issues and servitudes, a map of identified landscape settings, a map of wind resources, and an assessment of exploitable areas and of potential production. The report proposes a detailed overview of various issues: in terms of environment, heritage (protected areas, regulations), landscape, and in terms of technical issues (civil, military and meteorological servitudes, housing, power grid, seismic and fire risks). Then, after a presentation of the assessment methodology, it indicates the determination of the exploitable area, of wind power per square kilometre, and of results in terms of potential power by 2020 and by 2030, and of avoided CO₂ emissions and jobs
