Abstract
Due to the raising of crude oil prices and green house effect, how to reduce energy consumption and green house emissions is an obvious objective for every country around the world. Generally, the transportation sector is the second large energy-consuming sector right below the consumption of industrial sector. As a result, how to develop more efficient public transport systems, and reduce energy consumption and greenhouse gas emissions in the transport sector is important. In bus services, the conventional diesel buses are still the mainstream in Taiwan while the emission has been defined as that of coursing tumors. With the development of science and technology, there are many new energy vehicles such as electric bus, hybrid electric bus, natural gas bus, fuel cell bus, and so on in the world. These buses can not only reduce air pollutions, but will also lower the noise level. Consequently, they can improve environmental quality.
In order to reduce the emissions and lower the degree of crude oil dependence, electric bus has become the mainstream in public transportation in the near future. Since there is not a clear comparative analysis in Taiwan, this study aims to develop a mathematical model based on using the concept of life cycle cost to analyze the differences in operating costs of the diesel bus, the hybrid electric bus, and the electric bus in a hypothetical environment. Moreover, numerical examples and sensitive analysis are also conducted to verify applicability of the models. The results of this study have shown that electric bus has significant benefits in terms of external costs. It is also shown that electric bus will have comparative advantage on conditions that government provides subsidies and imposes air pollution tax with consideration of its external benefit and energy savings.
