"Both gasoline and ethanol utilize nearly as much energy to manufacturer as they provide."
 
As regards gasoline, this statement is prima facie nonsense.> Date: Wed, 27 Aug 2008 11:12:31 -0400> From: [log in to unmask]> Subject: Bio-Diesel, vastly better than ethanol and gasoline> To: [log in to unmask]> > An impressive documentary recently; "FIELDS OF FUEL" has won many awards.> > The film eloquently contradicts approximately 600 articles published in> major media to bash bio-diesel. It reviews petrochemical's political history.> > Don't confuse this with Ethanol.> > Biodiesel certainly seems to be one of the best alternative power sources> available. Algae farms are now producing bio-oils from which fuel, food,> and plastic can be derived. Mere cold-pressing can extract oil which is a> main component of algae, by weight, 50%. It is now being offered at fuel> stations througout Europe.> > Bio-diesel oil tops the BTU efficiency studies. Both gasoline and ethanol> utilize nearly as much energy to manufacturer as they provide.
