Corbyn - well known Islington based expert on steel production, transport, and trade-offs in costs between transport and production - said it was not credible to "drag" manufactured parts 8,000 miles to the wind farm site. He is at least partly right; dragging the parts there would not be credible; but only an idiot of his ilk would think of doing so. Transport by sea, however, is quite efficient.
Corbyn is not the only idiot on this though; step forward Scottish Greens Fife MSP Mark Ruskell who addressed the STUC rally. He said there should be no offshore wind farm leases issued from the Crown Estate without the guarantee of local jobs... Why all this mania for local jobs, other than shameless politicking? It's obviously stupid when Trump does it, I think even the Beeb can see it then.
What then you might ask is the correct place to buy these bits from? The answer is obvious: you don't know. And neither do I. But to a first approximation, I'd guess that whoever offers the cheapest place subject to whatever criteria of reliability the purchasing company feels appropriate would be the best place. The idea that a bunch of idiot pols have anything useful to contribute to the analysis is laughable.
