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.

Distribution doesn't just include long distance distribution. It includes all the wiring between transformers and houses and all the internal wiring of the house and all the devices inside etc.

only residential wiring uses copper, everything from 350kV down to 400V lines is aluminum, and even in houses aluminum can be used too

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.
