| - In order to create ethanol, all biomass needs to go through some of these steps: it needs to be grown, collected, dried, fermented, and burned. All of these steps require resources and an infrastructure. The ratio of the energy released by burning the resulting ethanol fuel to the energy used in the process, is known as the ethanol fuel energy balance (sometimes called "Net energy gain") and studied as part of the wider field of energy economics. Figures compiled in a 2007 National Geographic Magazine article point to modest results for corn ethanol produced in the US: 1 unit of energy input equals 1.3 energy units of corn ethanol energy. The energy balance for sugarcane ethanol produced in Brazil is much more favorable, 1 to 8. Over the years, however, many reports have been produced with contradicting energy balance estimates. A 2006 University of California Berkeley study, after analyzing six separate studies, concluded that producing ethanol from corn uses marginally less petroleum than producing gasoline. (en)

UU .: 1 unidad de entrada de energía equivale a 1.3 unidades de energía de energía de etanol de maíz. El balance de energía para el etanol de caña de azúcar producido en Brasil es mucho más favorable, de 1 a 8. A lo largo de los años, sin embargo, se han producido muchos informes con estimaciones de balance de energía contradictorias. Un estudio de 2006 de la Universidad de California en Berkeley, luego de analizar seis estudios separados, concluyó que la producción de etanol a partir del maíz usa un poco menos de petróleo que la producción de gasolina.
