'Bah, humbug' - le son et lumiere

When I crest the last hill on the remaining few miles of the M50 on my way back from London late at night, one of the most welcome sights is the spire of St Mary's in Ross. It is a sodium yellow-illuminated symbol that I am almost home. It is also, by virtue of needing several dirty great big lamps to achieve this effect, a rather major consumer of juice, and hence cause of the dreaded GeeGees (greenhouse gasses).

Now, do I storm up the the next parish whatever meeting and insist they blow them out right away? Well, it's a consideration, really, is it not? And hence a socio, enviro, and all sorts of other 'io's' dilemma.

'Cos that being the case, I should equally well be lobbing up at the next meeting of the guys who run Wembley Stadium, which as I leave London on the A40 is also rather pretty. Or the Millenium Bridge (pictured).

Sorry, no solutions. Like firework displays, I rather see me getting into hot water between heart and head just with myself, let alone with anyone else.

But as is my way, I do think it a question worth pondering. And I wonder how many stalwarts of the nan-e state and guilt-e activism have also decided these glowing icons to be best left out of the tsk-tsk finger-pointing.

Maybe one for a Prof's Poser... or London's Mayor. Relative to the additional emissions (above simply driving around in, say, a Prius) of all the 4x4s in the city, what would be the negative GeeGee impact be relative to purely decorative illumination of public buildings? I'm not even sure which side of a hundred it would go.
