It has proved be useful industrial strategic planning. concept SPI based on assumption that truly society basis economy flow solar exergy. conversion exergy services needs area. Thus, area becomes limiting factor economy. evaluates areas needed provide raw materials energy demands accommodate by-product flows from way. relates these available citizen given geographical (from regional global) context. data necessary calculate usually known at an early stage development. result computation ratio between supply with service all possible services. it expense this oriented towards sustainability.
