Electric Vehicles and Environmental Sustainability: A Comparative Analysis with Conventional Vehicles

Abstract

The increasing environmental concerns associated with climate change, air pollution, and fossil fuel depletion have intensified the need for sustainable transportation solutions. Electric Vehicles (EVs) have emerged as a promising alternative to conventional internal combustion engine (ICE) vehicles due to their potential to reduce environmental degradation. This study presents a comparative analysis of EVs and conventional vehicles in terms of environmental sustainability, focusing on carbon emissions, energy efficiency, and overall ecological impact. The analysis reveals that EVs produce zero tailpipe emissions, significantly reducing greenhouse gas emissions and improving air quality in urban areas. In contrast, conventional vehicles contribute heavily to carbon dioxide (CO₂) emissions and air pollutants such as nitrogen oxides and particulate matter. Furthermore, EVs demonstrate higher energy efficiency, as electric motors convert a greater proportion of energy into usable power compared to internal combustion engines. EVs are not entirely emission-free when considering the entire lifecycle, including electricity generation and battery manufacturing. The environmental benefits of EVs largely depend on the energy mix used for electricity production, with renewable energy sources enhancing their sustainability. Additionally, concerns related to battery disposal and resource extraction remain significant challenges.
