Throughout its history man has used emergia as a useful tool to evaluate the efficiency of productive systems even for a long time, and because of the lack of knowledge of the advantages of using the emergia analysis, he has not been given, greater utilization.

Every year a considerable number of different types of energy are in different production processes generated, but only a certain part is recognized and accounted, since most are lost because of the ignorance of the benefit it represents, the power to use it, on put it at the service of ecosystem. Faced with this problem, we try to demonstrate the importance of the study, and the implementation of methodologies, leading to a closer approach to sustainability. In the present bibliographic review, an approach is made on the subject of Emergence. In addition, it summarizes aspects related to the nomenclature to be used, as well as indicators and indexes more common to evaluate. Finally, some examples are presented, in which the use of this methodology has been, successful, while reflecting on the importance of the subject future research.
