Nukes, geo-thermal, Solar, wind, tidal, whatever. And, just to press the
point home, I did a little research a while back on the aluminium industry.

* Back in 1989, electricity costs were around 50% of the present level (in
Australia).
* Aluminium was around US$600.00/Tonne.
* The electricity cost to smelt 1 Tonne of aluminium in 1989 was
approximately $200.00/Tonne.
* The aluminium industry (in Australia) was profitable in 1989.
* The electricity cost to smelt 1 Tonne of aluminium today was approximately
$400.00/Tonne.
* The aluminium price today is close to US$2,500.00/Tonne.
* Even using the most pessimistic cost increases, due to greenhouse
reduction costs, the aluminium industry (in Australia) will still be very
profitable.

The aluminium industry continually bleats about high costs. They don't
menton the massive profits.


Interesting. I excavated some US numbers on aluminum. Each page has
about 5 years worth of annual costs. Sorry for the mess:

Price (not adjusted for inflation)
US$ per lb
2010 1.214
2009 1.252
2008 1.205
2007 0.794
2006 1.017
2005 0.688
2004 0.649

2002 0.840
2001 0.880
2000 0.771
1999 0.655
1998 0.657

Looks to me like the price of aluminum doubled between 1998 and 2010
in the US. That's about right considering the increased cost of
industrial electricity. However, it seems that the price in Australia
went up by 4.2 times. Was there something that happened in Australia
during this time period to produce this difference?
