Hi Russ,

Re: Come on you mean to tell me copper is not used in the electrical generation, transmission and distribution grid?

I made no such claim. I stated, correctly, that the conductors in the T&D system are overwhelmingly aluminum (Note 1). You've just slipped in electrical generation, which wasn't part of your original claim. It is a fact that copper finds use in the windings in generators, motors and transformers.

But my point was, and remains, that the T&D system is not dependent upon copper. It is constructed with aluminum conductors except in rare circumstances, such as the heavy copper conductors that power trolley cars in major cities such as San Francisco, for example, or the catenaries that power electric intercity trains such as Amtrak uses on the Bos-Wash Corridor.

Re: 60% of all the copper produced worldwide is used in electrical applications.

Yes, exclusive of transmission cables. :)

Note 1: tinyurl.com

This monograph clearly describes the current state of the art for transmission conductors:

"Today’s overhead transmission lines consist of aluminum conductor strands wrapped around a steel core."

This is a far more technically correct version of reality than you provided with the schoolbook version from energyquest.ca.
