[Terrapreta] Biofuels a study

[Michael Bailes]

The results of the study showed that when compared with gasoline and diesel,
ethanol and biodisel from corn and soybean rotations reduced greenhouse gas
emissions by almost 40 percent, reed canarygrass by 85 percent.

 Greenhouse gas emissions were reduced by about 115 percent for switchgrass
and hybrid poplar.

 Both switchgrass and hybrid poplar offset the largest amounts of fossil
fuels reduced emissions compared to other biofuel crops and offset two times
as much fossil fuels if they are used for electricity generation via biomass
gasification.

Study results showed that nitrogen (N2O) emission resulting from production
of the biofuel crops is the largest greenhouse gas source, while displaced
fossil is the largest greenhouse gas sink followed by soil carbon
sequestration.
