Balance energético del etanol brasilero: comparación entre métodos de medición.
As with any other bioenergy product, bioethanol production requires fossil fuel inputs; hence the alleged benefits of energy security and carbon mitigation depend on the extent to which these inputs are capable of drawing a substantive bioenergetic yield. Brazilian ethanol, made out of sugarc...

| Sumario: | As with any other bioenergy product, bioethanol production requires fossil fuel
inputs; hence the alleged benefits of energy security and carbon mitigation depend
on the extent to which these inputs are capable of drawing a substantive
bioenergetic yield. Brazilian ethanol, made out of sugarcane, has been reported as
the most efficient gasoline substitute that is commercially available nowadays. For
that reason it has been the object of several analyses on the energetics, i.e. energy
balances. These studies surprisingly vary widely according with the scholar
approach and are not fully comparable among them due to divergences in the
assessment method. This paper standardizes results of the four most prominent
authors in the field, establishing a point of comparison and drawing some light on
the energetics studies on biofuels. |
