Abstract
Sustainable supply of minerals and energy is global problem. Metals and energy consumption in the Asian countries has increased rapidly with economic growth. The analysis could proceed to examine the role of past trends in GDP and intensity of use in explaining the growth of metals and energy demand in the representative Asian countries, coming presumably to the conclusion that copper demand in Asia could continue at recent rates for at least the next decade or two. Considering the present situation of metals and energy there are anxieties about steep depletions of these resources. Instabilities in the supply and demand of mineral resources in the past were caused by distribution problems or extremely uneven supplies of resources, but the world's mineral productions have now become so large that for the first time in our history, it is questionable whether the world supply of these resources will last well beyond the lifetime. We examine a few depletion patterns such as Hewett and Hubbert diagram from this point of view.
