I was only talking about our situation in NZ, to make the most of the hydro we already have. Maybe we shouldn't be making aluminium in a less efficient plant, when we could be running most of our vehicles on that energy, at say 80% efficiency. Worldwide, I think fission (and later fusion energy) will be what is needed to fill the gaps. Assuming economies continue to grow. What if they go backwards?
Warmest November day in NZ, since records began. Not a record I'm that happy about.
