Conversion of Conventional
Passenger Bus to Electric Public Utility Bus (ePUB)

White Sheet
RATIONALE

               Public utility buses are a backbone of urban transportation, providing an affordable and efficient means of travel for millions of people every day. These buses are essential in reducing traffic congestion, lowering the carbon footprint per passenger compared to private vehicles, and offering reliable transportation options in both densely populated and underserved areas. However, the widespread use of diesel engines in these buses poses significant environmental and health challenges.

               Diesel buses have traditionally been favored for their durability and fuel efficiency over long distances. Despite these advantages, they emit high levels of carbon dioxide (CO2) and other harmful pollutants, such as nitrogen oxides (NOx) and particulate matter (PM). These emissions contribute to global warming and have severe health impacts, including respiratory and cardiovascular diseases. The shift to electric buses offers a promising solution to these problems.

               Electric buses, powered by batteries, produce zero tailpipe emissions, substantially reducing urban air pollution. When the electricity used to charge these buses comes from renewable sources, the overall environmental benefits are even greater. Additionally, electric buses are quieter, reducing noise pollution in cities. The operational cost savings due to lower fuel and maintenance expenses further enhance their appeal, making them a financially viable option in the long run.

Abstract Futuristic Background

Objectives of the Project
