Document Summary
As stated in the textbook, 7% of the worlds total energy supply is consumed solely for the e(cid:454)tra(cid:272)tio(cid:374) of (cid:373)etals. This large portio(cid:374) of the world"s e(cid:374)erg(cid:455) used is due to the immense amount of difficulty and techniques used when extracting this non-renewable resource. Also, as the extraction of metals is possible in greater quantities, areas with large concentrations of these metals become more and more uncommon. Steel alone accounts for about 5% of the worlds total energy consumption. It is amazing to think that we are producing power for the world (as canada is a large power exporter) and a fraction of that is used in the extraction and processing of metals: define the following terms. I will sometimes give bonus marks for especially good answers: mineralogical barrier. Skinner describes the section between the two peaks, that concentration of the metals is non-existent.
