Abstract
The growth in population, economic expansion, and urban dynamism has collectively driven a surge in the use of public and private transport, resulting in increased energy consumption in this sector. Consequently, the transport sector requires an energy transition to meet mobility demands, foster economic growth, and achieve emission reduction. The main objective of this article is to systematically review the literature on energy transition in transportation, categorizing research, identifying barriers, and providing analysis to guide future steps, with a special focus on developing countries. The methodology used in this study follows a sequence for a systematic review based on an evidence-informed approach and specific guidelines for systematic reviews, exploring the concepts, methodologies, and policies within the context of the energy transition, considering transport modes and geographical scope. The findings indicate that electricity is the predominant energy source in this transition, although its prevalence varies by transport mode. Biofuels present an alternative, primarily contributing to emission reduction associated with fossil fuel use. Natural gas emerges as a cost-effective option for heavy transport, while hydrogen represents another alternative, with the challenge of developing recharging infrastructure. Determinants of this transition include recharging infrastructure, tax and nontax incentives, public policies, the generation of electric power from renewable sources, and the management of battery life cycles from mineral extraction to disposal.
