Green after all?

The BBC obviously read my blog about the environmental damage of the shuttle, and sent a journalist scuttling to investigate the hot sensation that I exposed.


Their response seems to suggest that it's environmental impact isn't too great, since the thrust engines' fuel only releases water vapour (that's a real simplification, but is the essence of the article).

Fair enough, I suppose, but as some of the article commenters point out, how much energy is used to create those millions of litres of fuel? I can't believe that that's an efficient process. Wikipedia doesn't seem to hold the answers, neither does Google, or, unsurprisingly, the NASA site.
