Yes that's true. But as others have mentioned, there is a tendency to situate aluminum smelting in places with hydroelectric power (Brazil, Canada, etc.) if they have it, either for the environmental factor, just the fact you have a large source of power to use and it can't move. I think if an entity is trying to tackle sustainability, to some extent any innovation is innovation. If you try to swing for the fences every time no one may ever get on base.
