The Promise and Reality of Sustainable Fuels

Challenges of world’s energy supply and fuels consumption are highly dependent on the use of fossil fuels, coal, petroleum, and natural gases. The depletion of these resources is a major challenge as it leads to an increase in prices and a decrease in the availability of energy. Therefore, renewable energy sources, particularly sustainable fuels become critically demanding. Renewable sources of energy and fuels are abundant and do not emit greenhouse gases or contribute to climate change. The promotion of efficient energy use techniques promises to reduce energy consumption, thereby conserving fuel supplies. The diversity of sustainable fuel supplies is another driving force for the stakeholders to explore in this direction to fostering development and commercialization. The exploration and production of more diverse energy sources like natural gas, nuclear power, and biofuels help to sustain a diverse and secure energy supply. This chapter summarized the background of energy development, different families of fuel supplies, Geopolitical instability and grand challenges of sustainable aviation fuels.
