Richard, the cost effectiveness of the aluminum smelting process is vastly due to the energy levels needed to render it efficient and worthy as Canadian Visitor's linked article points out.
To bring US smelters to tje level of Canadian production, you would need hydro-electric, or nuclear or coal plants that don't impede demand on the consumer side that would up the cost of electricity to the average joe and joanne.
Sorry but here's how Alcoa is planning to make better use of energy with partner Rio Tinto in a new joint venture.
