Global Sensitivity Analysis: a tool to analyse LCA variability of energy systems
نویسندگان
چکیده
Policy makers are nowadays debating about the future electricity mixes that should be deployed. The environmental impacts of electricity generation systems is one of the central issue for this debate. Environmental impacts of electricity systems have been widely assessed over the past decades, in particular with the LCA approach. Several literature reviews have shown the large variability associated with these results [1]. It leads sometimes policy makers to consider LCA as an inconclusive method [2]. Improving the understanding of the LCA results variability origins is a key issue to extend the use of LCA as a decision support tool.

Understanding Lca Results Variability: Developing Global Sensitivity Analysis with Sobol Indices. a First Application to Photovoltaic Systems
LCA has been extensively used in the last few years and a large number of studies have been published in the literature. These studies show a great variability in results of comparable systems. It somehow leads policy-makers to consider the LCA approach as an inconclusive method. Some attempts have been developed to assess LCA results variability; however, they remain mostly qualitative. In thi...
