A variety of biomass feedstocks can be used to produce transportation fuels, biobased products, and power. Feedstocks refer to the crops or products, such as waste vegetable oil, that can be used as or converted into biofuels and bioenergy. The broad, flattened surfaces of the leaves gather energy from sunlight, while apertures on their undersides bring in carbon dioxide and release oxygen. Chloroplasts are the site of photosynthesis, the process in which light energy is converted to chemical energy. The bottom line on energy cane becoming a suitable cellulosic feedstock for the future is dependent on several factors. The interest in the crop is justifiable based on several independent factors that separately indicate good potential, but when combined they clearly designate sorghum as a logical choice for bioenergy production. The reason for producing bioenergy feedstock is to produce renewable fuel, but one of the critical components in their production will be water.
