Thanks for that Biff. Chesterfield’s not far from us so I might have an informative day out.
Also, through links on that site, I’ve signed up to the Carbon Account. Not that I’m convinced about Global Warming but with all the power usage showing on a graph it might encourage me to cut down and save a bit of cash.
I'm surprised they haven't got something like that in Suffolk, seeing as how* it's the centre of the civilised universe and a veritable crucible of innovation.
