Nick Xenophon, apparently. [That's sarcasm.] He normally seems to me to be more sensible, but yesterday he rushed in to make some "we're obviously doing renewable energy wrong" announcement as a result of the South Australian state wide blackout before having any idea what might have been the real cause of the problem. (Something like 22 cases of pylons being bent - and lots and lots of lightning - has something to do with it.)
This in turn was too much of a temptation for Professor
Now, I should caution: I haven't heard anything about whether any of the State's wind turbines were damaged in the storms. (It would be a little surprising if they escaped completely unscathed, to be honest.)
But if the electricity market folk are saying that this blackout would have happened regardless of the source of electricity, and there are twenty or so cases of pylons being bent like pretzels, I suspect we can believe them.
Oh - and congratulations to commenter Brian at Catallaxy - who at 12.18 am, after the relentless pile on of know-it-alls about renewable energy had been mocking the State, finally said "err, actually it might not have had much to do with that, after all." I think he was the one voice of moderation in the thread.
Update: Chris Uhlmann, who is the ABC's resident renewables/climate skeptic, also gets a low grade for pumping up the issue of "instability" in the SA grid (because of wind power) before the full extent of physical damage was known. Come the revolution, he'd be the only ABC journalist I'd want sent to Siberia.
