Scotty, I’ve just sat through four days of zero sun, courtesy of Cyclone Alfred.
The chances of weather events like Alfred (or worse) increase as you move further north.
The whole argument for renewables is based around being tied into a grid, so if the weather isn’t favourable in one area, your able to draw power from another area.
A stand alone operation is simply too risky, especially went you are talking about an unforgiving substance like molten aluminium.
