[
This is an abridged amalgam of writings by me on nuclear power and climate change that I've published on BNC and elsewhere over the last two years. It has been updated with some commentary on recent events - the Fukushima Daiichi crisis, Germany's announced withdrawal from nuclear energy, and so on. I hope you find it useful].
Let’s start by establishing some common ground between my views and those ‘traditional’ environmentalists who oppose nuclear energy. As the Director of Climate Science and active researcher on the impacts of global warming on the biosphere at the University of Adelaide (Australia), I understand the seriousness of the climate crisis and the imperative for a rapid transformation of our energy system to technologies that emit no carbon when generating power. I also agree that atomic weapons pose substantial risks to the security of global society and need strict regulation, and that issues of nuclear safety must be held to high standards. I also suspect that most environmentalists recognise the dangers that many countries face – including Australia, Germany, Japan and so on – in being dependent of foreign oil for transportation infrastructure and agriculture, two of the arteries of the economy. Indeed, it is in the interest of all nations needs to move to energy independence that is based on clean, sustainable sources.
However, where I part way with many environmentalists in on our view as to what the solutions to these problems are. Many well-intentioned people hope to see a world without nuclear weapons or nuclear power, and unfortunately consider (wrongly) that the two are irrevocably intertwined. In the typical environmentalist worldview (I am, of course, deeply environmentally conscious), nuclear power is not only dangerous, but also unnecessary. Renewable energy, from sunlight, wind, waves and plant life, are clearly the answer, they believe. This is a widespread view – almost ‘common wisdom’ – and would be perfectly acceptable to me if the numbers could be made to work. Unfortunately,
they can’t, and there is no prospect of this changing
. To keep things in proper context, let’s quickly review the challenge. In the developed world (US, Europe, and other members of the OECD), we’ve enjoyed a high standard of living, linked to cheap fossil energy. This has encouraged energy profligacy, and we clearly and should cut back on wastage where feasible (and in situations where it is not being done due to market failures) – but this doesn’t remove the fact that we must also replace oil and gas, and that means a future surge in electrical substitution. In the bigger, global picture, however, there is no realistic prospect of even reducing traditional stationary power demand. A third of the world’s people have little or no access to electricity yet strongly aspire to get it. Even
if a country like India
, with more than 1 billion people, reached just a quarter of Australia’s per capita use, that country’s national energy demand would more than triple! It’s a huge challenge.
