Our Nuclear Temptation Fiddling while the globe warms

Adelaide Review

John Howard should be positioning Australia to be a world leader in the manufacture and application of renewable energy technologies. He should underpin this by committing Australia to generating 50 per cent of our energy needs from renewable sources by 2015. Nuclear should not be part of the mix.

Risk-free and proven technologies like solar, wind, wave and hydroelectric technologies can provide the solutions that Australia needs. The renewable energy generation path in combination with energy efficiency measures offers the most environmentally sustainable, socially responsible and immediately available solution to greenhouse gas reduction.

Nuclear power generation on the other hand is extremely costly, inherently risky, controversial and extremely slow to bring on line - ten years minimum. While the latest generation of reactors might be low risk, the possibility of catastrophic failure remains.

This compels us to apply the precautionary principle - the risk is too high and the consequences too dire to adopt the technology. Equally, the problems of nuclear proliferation and the hazards associated with the movement and disposal of spent uranium presents future generations with unacceptably high risks.

Some proponents of nuclear power suggest that these risks are outweighed by the threats that global warming presents. They argue that we have no alternative but to include nuclear power in the energy generation mix. But does the end justify the means in this situation? The reality now is that nations around the world are jumping on the renewable energy bandwagon for just this reason. Recently the Portuguese Government announced investments in excess of US$10 billion in renewable energy projects over the next five years.

Sweden and Austria are leading the way while the unlikely Arnold Schwarzenegger, Governor of one of the world's largest economies, has committed California to an ambitious renewable energy plan. Meanwhile, John Howard prefers to play wedge politics with the nuclear issue, hoping to promote division within the Labor Party on the mining and export of uranium. Community concerns about the safety of nuclear power plants, disposal of radioactive waste and nuclear proliferation abound.

The government will find it difficult if not impossible to allay these fears. It will also find it very hard to convince Australians that nuclear power makes economic sense. At around twice the price of power generated from dirty, coal-fired power stations, nuclear power is very expensive.

The reality is that nuclear cannot compete with coal in the absence of a carbon tax or subsidies. This would force the cost of coal generated electricity up, making nuclear and other options like solar, wind and geothermal more competitive. Over a relatively rapid period of time these technologies can displace the use of fossil-fuel-powered generators, positioning Australia as a world leader in the manufacturing and application of safe and carbon free renewable energy sources.

The race is on internationally with China emerging as a potential solar generation technology giant. The problem for Australia is that we are exporting too much of our solar expertise and not enough finished solar product Take the example of Shi Zhengrong who left his position in Australia as a solar technology researcher at the University of New South Wales in the early 1990s to realise his goal of successfully commercialising solar technologies. He now leads the $40 billion dollar Suntech solar manufacturing company employing over 2500 people in China. The company is 30 per cent Australian owned. Shi Zhengrong is set to export his goods back to Australia.

Australia is a renewable energy laggard. The Swedish government has committed itself to being oil free by 2020 and has put in place a raft of policy carrots and sticks that put Sweden firmly on the path to a renewable energy future. This does not involve the expansion of its nuclear energy program. Portugal has set ambitious greenhouse gas reduction targets which includes generating 40 per cent of energy from renewable sources by 2010.

John Howard appears to be fiddling while the globe warms.
