ABSTRACT
By the advent of the 21st century, we came across the problem of energy crisis and global warming, which made the whole scientific community rethink on the production, management, and conservation of energy and find new and sustainable sources of energy. Now a large fraction of the world’s total energy produced is used by the automotive industry itself. This is so because the total world’s trade is dependent on the transportation sector which is, in turn, driven by the automotive industry. So to obtain a completely green energy approach for a sustainable future it is very much necessary to make the automotive industry more energy-efficient, which will help in conserving energy and hence contribute to the dream of a sustainable future. For this purpose, in this chapter, we have included the possible enhancements in conventional Internal Combustion (IC) Engines and the futuristic technologies driven by sustainable energy sources like The Green Engine, Hybrid Electric vehicles (HEVs), and Hydrogen as a potential fuel for combustion engines (H2-ICEs). By incorporating these technologies in modern automobiles we can enhance their energy efficiency and hence can lead to a sustainable green energy-driven transportation sector in the future.
