Almost all biofuels used today cause more greenhouse gas emissions than
conventional fuels if the full emissions costs of producing these "green"
fuels are taken into account, two studies being published Thursday have
concluded.


A few years ago I saw a study which showed that it costs the equivalent
energy of 1.26 gallons of of oil to make 1.0 gallons of ethanol.. This
study was immediately denied by the tree huggers and it disappeared quickly.
