Life cycle assessment of diesel and electric public transportation buses cooney, gregory allen (2011) life cycle assessment of diesel and electric public transportation buses master's thesis, university of pittsburgh. From the research side, the project was a resounding success that produced some major fuel savings - but by the time the doctoral thesis was finished, the balance of customer demand had shifted from diesel hybrid buses to electric buses. This thesis seeks to understand what factors hinder or enable transit agencies to go beyond initial pilots to largely or wholly electrify their fleets, with the goal of that electric buses may already be more cost effective than diesel buses for many agencies primarily due to fuel and maintenance cost savings, but are sensitive.
In fact, electric three-wheelers and minibuses are ready for the market and they are competitively priced buses may be a bit more expensive initially but users would gladly pay more for cleaner air.
