For transmission lines, AAAC, AAC, and AACSR exist. For residential grid hookup, aluminum has been an option for a long time. While aluminum residential wiring has historical baggage of risky and bad practices, the problem with it is inherent fatigue failure. Copper should be required for residential structural high voltage wiring. Locating, mining, and recycling more copper is necessary because demand is far exceeding supply. Perhaps at some point in the future, we may need to mine disused 20th-century waste dumps for metals and rare earths we just threw away and failed to recycle.
