I believe this has alkredy been discussed before,

the raw materials depends on how you craft generators.

if you craft iron furnaces furst, you use iron and refined iron (and cobblestone, depending on the recepi you follow)

if you craft generators directly you use only refioned iron

so the list is made on the assumption you make generators from a furnace and a machine block, thus requiring no normal iron

this does however make the step by step instructions incorrect, as it mentions making iron furnaces.
