Abstract: | Several physical and chemical factors limit the production of biofuels, such as the complex process required for the conversion
of plant biomass into ethanol. For example, fossil energy inputs needed for the production of ethanol from corn is 1.59 liters
per liter of ethanol. One of the many factors limiting energy output from biomass is the extremely low fraction of sunlight
reaching a hectare that is captured by the plants. On average only about 0.1% of the sunlight is captured by green plants
per year. |
