There is no such thing as a non-energy commodity. All commodities require energy to obtain and process, and are at least to some degree dependant upon the cost and availability of energy. Some more than others, Aluminium being the most obvious example of one that is strongly dependant upon energy. Regards, Robin van Spaandonk http://rvanspaa.freehostia.com/project.html
