"     Coal is required for burning as energy in order to generate Power"
"   and hence money in the budget assessment.  It is also required for"
"   Steel production and Ship production.  It can also be converted"
"   (produced) into Oil.  This is an inefficient process but can be used"
"   to make up for shortfalls in oil production especially when used"
"   in conjunction with Nuclear Power to make up for loss of Coal Power"
"   generation."
