30% of the total used (including electricity losses) for the three major use
sectors; 1) commercial and residential, 2) industry, and 3)
transportation. The manufacturing industry accounts for about 80% of
industrial use, and designs and builds all of the equipment used in the other
major energy use sectors. So, manufacturing plays a very big role in
energy use in the </span></font><font size=2 face=Arial><span style='font-size:

appetite. For your entertainment we compared a production machine tool to
a SUV. We then look at new manufacturing processes. Again to a
first order, the energy used per unit of material processed, by new
technologies (nano scale processes, microelectronics processes, advanced
machining processes) exceeds older technologies (machining, injection molding
etc.) by (6-8) orders of magnitude.</span></font></p>
