Copper, instrumental to electric motors, sustainable electric generation and transmission, is in dwindling supply, unable to meet global industry demands. Copper is truly the red metal with the green future.  Copper electrical wires are safer to use than wires made of most other conductive metals because they are resistant to heat. As you can see, copper is the preferred metal for electrical wires for several reasons. It has high electrical conductive; it’s inexpensive; it’s ductile; and it’s thermal resistant
