INTEGRACIÓN DE MDMC EN EL ACV PARA EVALUAR ALTERNATIVAS DE ELECTRIFICACIÓN RURAL EN CERRO HERMOSO, OAXACA, MÉXICO.

Abstract

The need for a methodological framework for sustainable integrated management of renewable energies has been extensively investigated and discussed due to increasing environmental problems. In this realm, Life Cycle Analysis (LCA) has been the methodological tool used to measure the sustainability of a product or system. However, this alone is not enough to determine the total sustainability, since its structure only allows the calculation of environmental indicators, but one must also take into account that a product or a system is sustainable if it includes at least its environmental, social and economic evaluation. This gap in the methodology of the LCA obliges to look for new techniques that allow to complete the process of sustainable evaluation, mainly in renewable energy systems. In order to achieve this, two methods are combined in this work to try to evaluate renewable energy systems from the environmental, economic and technical viewpoint, through the LCA methodology, where Multicriteria Decision Methods (MCDM) are integrated into phases 1 and 4 of the LCA. As an example of this integration of methodologies in the assessment process, the evaluation of energy systems, specifically photovoltaic systems to electrify a rural community in southern Mexico, is taken as a case study
