电力需求的不断增长，以及对环境友好技术的需求，要求我们深刻认识到电力生产的方向，以满足这两种需求。这项工作的目的是利用能值函数及其相关指数来评估意大利电力系统的可持续性。能值函数是由奥德姆在80年代初提出的一种方法。能值是一个基于热力学的函数，它计算获得产品所需的所有能量通量，这些能量可以追溯到所投资的太阳能。我们分析了所有与电力产量相关的投入，不仅考虑了生产的最后阶段，还考虑了系统运行所需的所有来源和材料。我们对所有不同类型的生产进行了广泛的分析，重点是热电部门。我们不仅对电力生产进行了热力学分析，而且对整个过程的可持续性进行了评估，并提出了正确开发资源的设想。
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 early80s 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.
