A hi-tech society utilises energy, materials and information. Such a society utilises automation as much as possible to reduce work thus in such a society in becomes useful to use a measure of energy for resource monitoring and allocation. The article looks at the exergy concept as a way to measure energy utilised, materials and information for a hi-tech resourced based economy such as one that uses an energy accounting system.
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.
