the exergy loss calculation, is the basic working tool in this study. The final objective of PH is to use those calculated … in the river (they give the exergy value to water bodies), the exergy profiles of the river at different statuses (those … defined by the WFD) are obtained. Then, the environmental cost of water is obtained (in energy units) as the exergy needed to …

, that is the application of the exergy analysis in the evaluation of natural fluxes and resources on Earth, could help to … resource can be unified into universal units (energy units), and the monetary conversion of exergy costs is automatic through …

investment (EROI), which evaluates the ratio of fossil energy consumption during their production. This paper applies the Exergy … this principle is achieved using exergy instead of energy. For this purpose, it introduces a new sustainability indicator …, called ExROI, defined as the ratio between the exergy of a particular resource and the amount of exergy required to obtain it …

The second law of thermodynamics and, specifically, exergy analysis have been traditionally used for the assessment and … optimization of energy systems. Nevertheless, as shown in this paper, exergy could also constitute a powerful tool for the … evaluation of mineral commodities. That said, new or re-defined exergy-based concepts need to be developed. This paper presents …

This paper makes an inventory of the natural capital on earth in terms of exergy, which includes not only renewable and … non-renewable energy resources, but also non-fuel minerals. The exergy method is very suitable for the accounting of our … natural capital because all kinds of resources can be assessed with a single property. For the case of minerals, exergy allows …

, by using exergy, expresses matter and energy flows in the same physical units. Besides methodologies developed for … development of new methods such as those presented here. First, two decomposition strategies for exergy costs are proposed …

developed in a previous paper, the study will serve as a reference for calculating the exergy of the current mineral capital on …

of the enthalpy, Gibbs free energy and exergy of the bulk upper continental crust and of each of the nearly 300 most … abundant minerals contained in it. Finally, the chemical exergy of the continental crust is compared to the exergy of the … concentrated mineral resources. The numbers obtained indicate the huge chemical exergy wealth of the crust: 6 × 106 Gtoe. However …
