The article is shit, the study is about copper used for reducing fossil-fuel power generation. It is basing the projected use of copper on windmills and especially large batteries.
Those high-powered and long distance power lines are made aluminium and steel.
only residential wiring uses copper, everything from 350kV down to 400V lines is aluminum, and even in houses aluminum can be used too
Thousands of fires disagree
From old electrical connections that weren't designed for the different rates of expansion of aluminum and copper. Today, most of them are.
this was before we figured out that you can use stranded aluminum wire and it's fine this way
that, or copper clad aluminum
And that part is entirely independent from whether the electricity is generated with solar, wind or fossil fuels.
