Ian Lowe’s Quarterly Essay entitled Reaction Time: Climate Change and the Nuclear Option is a well-informed, well-reasoned and timely contribution to the current debate. He brings an unusual level of credibility to the debate. He is an engineer and physical scientist by training, with a doctorate in physics, and currently emeritus professor of science, technology and society at Griffith University–an orientation which fits him exceptionally well to handle the multi-disciplinary character of the issue. Interestingly, his early academic years in the UK in the 1970’s saw him as a supporter of nuclear power, and a participant in early policy reviews. In this essay he recounts the accumulation of data and experience that lead him to the opposite position. He is now President of the Australian Conservation Foundation, and has a clear position against nuclear power as a solution to global warming.

His essay covers a lot of ground, and is worth reading by anyone who wants an informed, although clearly–and unapologetically directed–view of the issues. He reviews the energy demands of the world, centreing on the emerging peak of oil availability, and outlines the global dilemmas implicit in this trend. In this he doesn’t retreat from a consideration of quality of life and well-being issues, or of distribution impacts between the developed nations and the poor of the world. He notes some important precursors in attempts to restructure societies in more sustainable energy directions (such as Alberta, Canada).

He summarises the evidence for climate change–evidence which he regards as incontestable–and the generic technical solutions: cleaner fuels and energy efficiencies. He then moves to a consideration of the nuclear option. He takes head-on the idea of nuclear technologies as the only ‘clean’ technology capable of addressing global warming. He covers the true costs of nuclear power, which he argues make it uneconomic; the world-wide retreat from nuclear reactors; the long time lags needed to bring nuclear energy on line; the threat from nuclear accidents, such as Chernobyl, and of nuclear weapons proliferation; the almost inconceivable lengths of time over which nuclear waste will have to be stored effectively, and the lack of a technology to do so; and the problems of low-grade uranium ores:

“Total life-cycle analysis has concluded that fuelling nuclear power stations from lower-grade ores actually releases more carbon dixoide per unit of delivered energy than burning gas. . .there is no doubt that the fuel energy, consequent greenhouse emissions and the dollars needed to produce uranium all increase rapidly as the ore grade declines.”

(This is a point referred to in my posting of August 20).

Lowe looks in some detail at the techical problems associated with economic projections over the long periods required by the analysis of energy options, and particularly the problem of discounting, which places far greater weight on the well-being of present as distinct from future populations. He analyses incisively the rather ludicrous policy developments in Australia, as the federal government has attempted to marshall some kind of ‘expert’ opinion in favour of nuclear power, in support of its economic objectives. He flags the agenda for nuclear enrichment in this country and the dangers inherent in it. He dissects the current policy, of both parties, to sell uranium into a deeply unstable international political environment. He notes the real possibility that Australia is headed for the role of a nuclear waste dump for the US.

Against this Lowe promotes the growing credentials of wind and solar power to provide an increasing proportion of the world’s energy requirements at reasonable costs. Notably, he points out that the current level of energy demand is not a given which has, at all costs, to be met: at the level of material prosperity enjoyed by this country in the 1960’s, he argues, a sustainable world could be equitably enjoyed.

Although this is a polemical document, its marshalling of arguments against the nuclear energy option and in favour of renewable energy options is an important statement, and one that, under the present push by the nuclear industry to rebadge itself as clean and green, to what it hopes will be a compliant and intellectually cowed society, is greatly needed. It should be widely read.

  1. I haven’t read his article in Quarterly Essay yet but I notice that in the Press Club address on the 12th Sept he talks about solar and renewables but leaves out entirely solar thermal power. If he wants to promote renewable power every time he speaks publicly it’s a given that he must include it. There should be no reason why it’s left out. The public is entirely unaware that renewable power in the form of solar or even wind can provide base power for industry 24/7. In the case of wind, distributed wind generators with vanadium redox batteries can do this and in the case of solar thermal, storage of the sun’s energy by rock or salts has been used but the star performer is the disassociation of ammonia closed loop storage system. This system does not loose energy and as a result the sun’s energy can be stored for any length of time and a summer sun can be used in wintertime. Adequate storage provides 24/7 base, medium or peak power on demand. A starting point for references to solar thermal power can be seen at TREC-UK, TREC Australia. The storage system at ANU high temperature solar research page. And there are other forms of solar thermal power e.g. the Solar tower at http://www.enviromission.com.au/
