Now if the Sceptic Tank is sure of one thing, it's that Peter Lilley, scourge of green campaigners, hates wind turbines.
This, after all, is a man who has been such an outspoken critic of renewable energy and taking action on climate change, that his recent appointment to the energy and climate change select committee caused all sorts of rumpus.
So imagine our surprise when a Greenpeace undercover journalist filmed Lilley apparently saying he "rather likes" wind turbines. It even sounds like it's his wife who has the problem with them.
It seems Lilley's main objection is that they are too expensive, which of course is a rather bizarre argument to make when onshore wind is already the cheapest renewable technology and is forecast to become cost-competitive with conventional power sources within the coming decade.
Anyway, with our faith so shaken we're now off to the woods to discover what exactly bears have been doing in there all this time.
