Definition of the Subject and Its Importance
Biofuels come in many forms and from a variety of sources. The biofuels may be solid (biomass), gas (biogas), or in liquid form (biodiesel, ethanol, etc.). Biofuels may be derived from most plant material as well as some animal parts, typically animal fats. As plants grow over much of the world’s landmass and their primary source of energy is the sun, biofuels are abundant and renewable. Furthermore, as biofuels absorb the sun’s energy to grow, biofuels are nature’s solar energy battery.
Biofuels have been used for thousands of years as a source of heat and light for civilization. However, as humanity’s energy consumption has become more sophisticated, fossil fuels have gained a technological edge in refining and supply chain management. For the last decade, renewed interest in biofuels has increased the adoption of biofuels for making heat and electricity. The drivers for the interest in...
