The continuously increasing demand for electric power together with the demand of environmental friendly technologies require a deep acknowledgement of the directions to give to electric power production in order to satisfy both necessities.

Abstract
The continuously increasing demand for electric power together with the demand of environmental friendly technologies require a deep acknowledgement of the directions to give to electric power production in order to satisfy both necessities. The aim of this work is to evaluate the sustainability of Italian electric system by using the emergy function, a methodology developed in the early 80s by Odum, and its correlated indices. Emergy is a thermodynamic based function that calculates all the fluxes of energy requested to obtain a product going backward to the solar energy invested. We analyzed all the inputs concurring to the yield of electricity taking into account not only the final phases of the production but also all the sources and materials that had been necessary for the system to operate. We have performed a wide analysis of all the different types of production focusing on thermoelectric sector. We have obtained not only a thermodynamic analysis of electricity production but also an evaluation of the sustainability of the entire process and a scenario for a correct exploitation of resources.File | Dimensione | Formato | |
