> Copper shortage threatens green revolution No it doesn’t. Aluminum exists and is a decent electrical conductor. I suspect this article was written by an LLM and prompted by someone who doesn’t know as much as they think they do. All transmission and distribution conductors are aluminum wrapped around a steel core. Utility service drops in cable form are usually aluminum, a 200A 240V overhead service drop in the US is a triplex cable with (2) #4/0 aluminum conductors for the 120V legs and (1) #2/0 aluminum neutral conductor. Most of the low-voltage (480V primary, typically) transformers I buy have aluminum windings. Most of the 400A and under panelboards I buy have an aluminum bus, and some of the larger ones do too. Silver plated copper bus is still used, but aluminum is cheaper.
