Fossil fuels are currently the primary source of energy needed by the planet. The hunt for renewable, less harmful energy sources has been fueled by the world's rapidly increasing need for energy and the carbon dioxide emissions that come with using fossil fuels. Among them is regarded as ethanol. It is really regarded as one of the best biofuels for transportation since it can be mixed with gasoline or burnt straight to increase fuel combustion in cars, which lowers CO2 emissions and lowers atmospheric gasses. As a result, research has shifted to the creation of increasingly sophisticated technologies in order to achieve energy sustainability and reduce greenhouse gas emissions. These factors led to the development of two additional production techniques that concentrate on the fermentation of cellulose and hemicellulose mostly from second-generation agricultural wastes and third-generation algae. The facts on the possibilities and applications of producing bioethanol from first, second, and third generation feedstock have been critically analyzed and presented in this chapter.
