"No Sheffield Forgemasters loan, no new nuclear by 2017," says Chris Goodall in The Guardian. Cancelling a government loan to Sheffield Forgemasters could derail UK plans for new nuclear reactors.
That, one suspects, was the intention of the Cleggerons – and especially the ghastly Huhne – when they cancelled the loan. Interestingly, the little Cleggy is a Sheffield MP and his name is mud (or something that looks like mud) in the Parish. Red hot pokers (heated free by Forgemasters) would be very usefully employed.
And this is your answer. Sod the carbon footprint.
