Just over a year ago, in the January 2006 issue, I wrote in the
Publisher’s Letter that Australia should build nuclear power stations.
Furthermore, I advocated that it be used to power the proposed desalination
plant in Sydney.
Well, the political climate has certainly changed since then!
The New South Wales Government has back-tracked on the desalination plant, in
the forlorn hope that it would rain enough to fill the dams. Didn’t happen, did
it? But on a more positive note, the Federal Government commissioned a report
from Ziggy Switkowski, on "Uranium Mining, Processing and Nuclear Energy". This
294-page report has just been released and the omens are generally favourable to
nuclear power.
Having read the report, I can summarise it in the following
way: Uranium mining is generally safe and worthwhile for Australia and we should
produce more of it; Uranium processing is very expensive and we shouldn’t touch
it with a barge pole and finally, Nuclear Power is safe but much more expensive
than Australia’s existing coal-fired power stations. It will never be
competitive with coal-fired power stations unless a substantial carbon tax is
levied on them.
There seems to be little doubt about the first part: we should
export more uranium to other countries. The second part also seems indubitable –
so don’t process in Australia. The third part is more questionable – should we
bother with nuclear power if we have to artificially make coal power more
expensive to make nuclear power viable? I suggest that is the wrong question.
The Federal Government is unlikely to bring in a carbon tax on all coal-fired
power stations just to make nuclear power stations viable and nor should it.
Rather, if nuclear power stations are to be built, to reduce Australia’s
greenhouse gas emissions, the Government should make a policy decision that
nuclear power stations will be part of the national grid and will be able to
sell their higher-cost electricity to it – just as higher-cost wind power
already is. Consumers will pay more but they are likely to pay more in the
future, whether we have nuclear power stations or not.
Having said that, some of the assumptions in the Report seem
questionable. For example, Australia’s electricity demand is estimated to double
by 2050, even though energy consumption per unit of GDP is declining.
Furthermore, as stated in the Report, "consumption is expected to grow at around
2 per cent per year to 2030. The bulk of the electricity will continue to used
in industry and commerce but domestic consumption is also expected to
increase".
In effect, the Report says that electricity consumption will
continue to grow inexorably and there will be no real drive for businesses and
households to reduce their power use. So will we continue to waste ever more
power? I suggest that if water consumption in all Australian cities can be
drastically curtailed by stringent restrictions but little in the way of
economic sanctions (ie, price rises), then there must be enormous scope for
reductions in electricity consumption over the next 40-odd years, with no
reduction in economic output or living comfort.
Think about it: the majority of households could undoubtedly be
re-designed to provide just as much, if not more, living comfort while using
substantially less energy. This has been done on a very large scale in Europe
and the USA. And undoubtedly, most businesses could affect major savings in
electricity consumption if they really had to, because of higher prices or
restrictions.
So by all means let’s build some nuclear power stations to
provide base load power while reducing our overall greenhouse gas emissions. But
let’s not just continue to use electricity wastefully. Surely, we are more
clever than that.
