dc.description.abstract | The important issues of energy sustainable development include energy security, energy management and efficiency, energy prices and market liberalization, energy technology and industrial development, cap-and-trade. To decouple economic growth and greenhouse gas emissions, energy efficiency improving and cap-and-trade mechanism are the most important instruments to advanced greenhouse gas abatement.
This research established the Taiwan Sustainable Energy Development (TaiSEND) model to assess energy and environmental policies. TaiSEND is a national dynamic computable general equilibrium (CGE) model, which represents the interaction between economic agents, development of energy technologies, and limitation of energy resources.
Energy intensity or energy productivity is the most popular measures of energy efficiency of the country level. But the essentially difference between productivity and efficiency, and without driving force information from a single indicator, make energy productivity inappropriate for energy efficiency. This paper extends the method of Feijoo et al. (2002) and proposes a new energy efficiency indicator, which is calculated from the loss of the energy without allocation and technology efficiency. The results show that the energy productivity would be misleading to present the changes of energy efficiency.
On the other hand, the national and sector level marginal abatement cost curves (MACCs) need to be determined before the allowances and emission trading, which is a cost efficient abatement instrument. In Taiwan, there are two approaches to estimate sector level marginal abatement cost, which are the technology-based and market-based marginal abatement cost curves. The former one ignores the market effects and the latter one does not account the potential CO2 reduction of innovative technologies. This thesis builds up the market-based MACCs with TaiSEND model, then includes the technology-based marginal abatement cost information. The results present that the MACCs will rotate in different ways inter-sectors under considering the technological reduction costs, such as energy and the residential sector will become gentler, the other sectors become more steep. These outcomes will change the allocation of emissions allowance.
