Energy Systems Language
From Wikipedia, the free encyclopedia
The Energy Systems Language (right) was developed by the ecologist Howard T. Odum and colleagues for depicting the flows of energy qualities in general: i.e. in ecological, economic systems, or ecological economic metabolism. The language is a generalisation of electronic schematics. All systems depicted with the Energy Systems Language can therefore be defined in electronic circuits, and the mathematics thereof. Even though the Energy Systems Language is used to model ecological and socioeconomic systems, because it is definable in electronic circuits, the laws of physics are a necessary part of the language, and any models produced. In order to aid learning, pictograms have also been used to depict the basic categories of the Energy Systems Language.
