kryptonjohn: That said, if they ever shut down Tiwai Point smelter, this could be a good use for the Manapouri hydro power, given it is in the "wrong" part of the country.
Global warming and CO2 is a global problem. Shutting down Tiwai Pt and re-appropriating Manapouri is a foolish environmental move. It will solve zero on a global scale because the Aluminum it fails to make will instead be made in a coal powered smelter in China/Australia/USA/Russia.
The world is always going to need aluminum, and it takes a lot of electricity to make aluminum. If NZ wants to be a responsible global citizen that contributes to reducing CO2 in a meaning full way, while growing our economy, we need to be building 10 more Manapouri's, building new Aluminum Smelters and putting the dirty coal powered smelters out of business.
The problem at the moment is we don't have the gumption of our parents/grandparents who built all the hydro dams. Even though hydro is the goose that lays golden eggs, and right when the fate of the world depends on it we can't seem to pull finger and build some more.
Exactly. Its true that greenies dont want that, pity as you alluded to in the previous post, a hydro installation isnt taking over the world. Its vastly altering a very small plot. The result is reducing effect on other plots. I posted a link on the EV thread that solar PV is choking AUS electricity grid.
Ill grab it now
If we can work toward this...
