The history of Money
Usually, we tend to think that money arose with coinage during the late Iron Age. Before that, human beings generally bartered goods directly, we are taught. The facts are far more nuanced and poised towards a gradual evolutionary development of currencies that have followed similar patterns throughout the world.
It is true that when trade was infrequent, goods were primarily exchanged as barter or gifts. When agriculture was developed, the population grew and villages turned into towns, trade became more and more habitual. Thus, with soon to be dozens of different goods exchanging owners in buzzing markets, trade became more and more complicated. Soon, certain goods evolved beyond their usage utility to serve as “key goods” to obtain other goods.
As our current socioeconomic system does not have a sustainable nature thus, it will collapse. This paper presents an alternative to today's system that utilises exergy as a common accountancy unit for a sustainable resource base socioeconomic system. An item's cost, in terms of exergy, reflects the physical cost of the item. The system utilises management techniques such as optimisation, Life Cycle Analysis and Cost Based Analysis to produce items efficiently and minimise their exergy and environmental cost.
