Hero's why: Nearly everywhere coal yields more BTU's per dollar... modem combustion installations step up litis inherent economy... up-todate coal- and ash-handling systems cut labor costs to a minimum. Tremendous reserves give coal a future depend ability of supply no other fuel can offer. And to mine this coal, America has the world's most productive end efficient coal industry--making coal the one fuel most likely to remain reasonably stable in price.
