“…• Uses of exergy are increasing in fields related to environmental impact [17,[29][30][31][32][33][34][35][36][37][38][39][40]. That work is aimed at understanding environmental impact better, and developing better predictors and indicators of environmental impact, especially for environmental emissions.…”

“…On a deeper level, several researchers have suggested that a potentially useful way to link the second law and environmental impact is through exergy because it is a measure of the departure of the state of a system from that of the environment [29][30][31][32][33][34][35][36][37][38][39][40]. The magnitude of the exergy of a system depends on the states of both the system and the environment.…”

Exergy is compared with other indicators for the environmental impact of waste emissions in an effort to better understand its potential as, or as the basis for, an effective indicator of the potential of an emitted substance to impact the environment. Relations between environmental impact and exergy in general and chemical exergy of waste emissions in particular are observed to support the use of exergy as such an indicator. The measure of disequilibrium with respect to a reference environment provided by exergy is considered, along with the consequence that the exergy of unrestricted waste emissions has the potential to impact the environment. Exergy is observed to exhibit many characteristics of other indicators of environmental impact, which are mainly empirical in nature. An exergy-based indicator could contribute to the development of rational and objective procedures for assessing the harmful effects on the environment of a substance and predicting its potential for environmental impact. The potential usefulness of exergy in addressing environmental problems is concluded to be significant, but further research is needed to develop objective exergy-based indicators that are practical for the potential of a substance to impact on the environment.

“…The exergy of a system is zero when it is in equilibrium with the reference environment. The tie between exergy and the environment has implications regarding environmental impact has been investigated previously by Sciubba [23]; Rosen and Dincer [24e26]; Gunnewiek and Rosen [27]; and Daniel and Rosen [28].…”

SUMMARYA comparison is presented of the main approaches to second-law analysis (SLA) reported in the literature. Five SLAs are considered: exergy, physical-exergy, exergy-consumption, negentropy and entropy analyses. The application of the SLAs is illustrated through an example. In addition, several significant implications of SLA are examined in the fields of environmental impact and economics. The presentation herein of the approaches to and implications of SLA is expected to enhance understanding of SLA and improve its usefulness.
