Eco-Friendly and energy efficient vehicles

This paper mainly intended to highlight the importance of sustaining the technology of eco-friendly vehicles. This paper starts with a history of energy exploitation by a human being. The transition of energy source exploitation is running thru from the early renaissance time until this modern era of industrial revolution 4 (IR4.0). The internal combustion engine, in general, has served the world since early 20th-century driving until now. The depletion of oil reserves and the need to retain a green environment indicate the utmost important action must be taken to find an alternative source for new energy. This paper also highlights the concept technology cycle which in general, internal combustion engine technology has to reach the maturity stage, and innovation is needed to keep the engine technology up to date and create less pollution at the same time. Also, this paper reviews the factors that will drive towards technology innovation and the progress of the eco-friendly vehicle
