Intégration de l'analyse de cycle de vie dans l'étude de la production électrique en milieux insulaires

Abstract : Population growth, the raising of the standard of living and quality of life, and energy-intensive activities are key parameters affecting the territory energy demand, through electricity consumption. To meet this demand, reliance on fossil fuels is the main adopted solution, particularly in insular context. The downside of this method is the large amount of greenhouse gas emissions (GHG) emitted, and vulnerability of the territories. Current policies are now in favor of the energy self-sufficiency as a medium-term objective, and put in place measures to support the use of sustainable energy sources to mitigate GHG emissions. This work aims to assess environmental impact of electricity production in Reunion island, to establish a territorial diagnosis. Based on a life cycle assessment approach, according to ISO 14044 standards, varying environmental impacts have been evaluated from existing power plants. An evaluating tool has been developed to identify the most emissive life cycle stage from 1 kWh electricity produced. The obtained results serve as a reference point to develop prospective scenarios. Eight scenarios have been presented and aim to satisfy environmental, technical, social and economic constraints.
