Against my better judgement, I got sucked into a minor Twitterstorm over the weekend. The main outcome was to remind me that, while Twitter is useful in the role of a microblog, providing quick links to, and sharp observations on, more substantial material, it is utterly useless as a venue for discussion and debate.
Update : A large number of nuclear fans were eager to tweet and share snarky responses on Twitter, but only three people were willing to discuss the issue here. Thanks to David Michie, Jonathan Suhanto and Ben Huxham who did at least respond. For those concerned that I might have a home-field advantage, I suggested that they post a long-form response on a site of their own, with links here, but no one took this idea up. That says it all for Twitter, and for the pro-nuclear posters there, as far as I’m concerned. End update.
In this case, the debate was over nuclear power, and this post from last year. It’s reasonable to ask why I would bother arguing about nuclear power, given my frequently expressed view that it’s dead as a doornail. The problem is that nuclear fans like Ben Heard are, in effect, advocates for coal. Their line of argument runs as follows
(1) A power source with the characteristics of coal-fired electricity (always on) is essential if we are to decarbonise the electricity suppy
(2) Renewables can’t meet this need
(3) Nuclear power can
Hence, we must find a way to support nuclear
The problem is that, on any realistic analysis, there’s no chance of getting a nuclear plant going in Australia before about 2040 (see over the fold). So, the nuclear fans end up supporting the Abbott crew saying that we will have to rely on coal until then. And to make this case, it is necessary to ignore or denounce the many options for an all-renewable electricity supply, including concentrated solar power, large-scale battery storage and vehicle-to-grid options. As a result, would-be green advocates of nuclear power end up reinforcing the arguments of the coal lobby.
