] dependence on foreign oil. So two years ago, the Phoenix
] concrete producer began using biodiesel--made from
] refined soybean oil--to fuel his fleet of 130
] diesel-powered cement mixers and excavators. For his
] efforts, Goodman in 2001 won a local entrepreneur of the
] year award and plaudits from the Environmental Protection
] Agency (news - web sites). But protecting the Earth was
] not Goodman's only concern. "Let's start with national
] security--the billions and billions we waste dancing
] around the issue, protecting those pipelines, invading
] Iraq, doing whatever else we're doing in the Middle East.
] It all gets down to continuing the flow of oil to this
] country."
