 Road transport is an essential component of any nation's economy as it provides the mains to move both people and goods quickly and efficiently. However, it is also one of the largest contributors to air pollution and greenhouse gas emissions. To address this issue, many countries have begun to explore alternative energy sources and technologies to reduce the environmental impact of road transportation. This paper examines various energy sources, including fossil fuels, gaseous fuels, and other renewable sources, as well as technologies that can be used to recover energy loss during vehicle operation. It also looks at future developments in the field of energy harvesting in vehicles. This article was authored by Yasek Kaban, Jan Vrabel, Dorda Gornica, and others.
