Sure, depending on the application you can just redesign to larger gauge aluminium. Aluminium has useful mechanical properties that trump the lower conductivity (such as power lines,where thermal cycles can make copper brittle). You could argue that there is a silver shortage in a similar way as the article has argued a copper shortage...
- midoridensha 4y agoThe lower conductivity of Al isn't important: you just use larger wires to make up for it and get the same resistivity. Al is so cheap that it's still much cheaper than Cu even with thicker wires. Al also has low density, so even with thicker wires, it isn't as heavy as Cu, which is important with power lines.
