question about embodied energy

[yoshhash2]

I get the general gist of it, and even studied up on the various theories within on wiki, but there are some things I don't understand:

I have seen tables that show the embodied energy for standard things like bricks and sheets of plywood, etc. There seems to be a certain amount of consensus, but I seriously have to wonder if this is because they are all just copying from one source.

 

Does anyone know of a reliable, peer reviewed source that breaks it down further, showing where they get these figures? I need to know, when they calculate, do they account for other factors such as transportation, storage, the amount of waste produced, ease of disassembly and disposal, or how to account for materials which may have been diverted from the waste stream.
