DESCRIPTION:After a brief explanation on the origin of this talk\, a worki
 ng definition of sustainable growth will be proposed. The major difference
 s between developed and developing countries will be identified. Using an 
 approach borrowed from Ashby\, it is possible to categorise materials in t
 erms of price per weight of manufactured products. The possible role that 
 these different categories can play in terms of sustainable growth will be
  examined\, notably in the light of a predictable energy shortage for the 
 21st century. This leads to an analysis\, limited to metallic materials\, 
 of some major shortcomings and their possible origin\, essentially for lar
 ge volume commodity materials\, with low added value. Indeed these consume
  significant amounts of energy both in their production and in their use\,
  as well as playing a key role in energy production.\n\nFinally\, an attem
 pt will be made to identify the possible key role of electron microscopy i
 n the improvement of existing metallic materials and in the development of
  "new" high volume alloys and composites.
