WASHINGTON (Reuters) - Senators who support the Pentagon's push to expand its use of biofuels said they have a plan to answer critics who argue the fuel is far too expensive to help develop at a time when the military faces massive cuts.
The battle on Capitol Hill comes as the U.S. Navy's "Great Green Fleet" prepares to run military exercises in the central Pacific that will, on Thursday, feature its first operational test of biofuels.
