碩士 === 嘉南藥理科技大學 === 環境工程與科學系碩士班 === 95 === The purpose of this study is to explore the trend of CO2 emission in the electricity industry. An input-output analysis and FGP along with the IPCC method are employed to estimate the volume of CO2 emission produced from power sources in the electricity industry from 1996 to 2006, focusing on the correlation between derived energy and carbon dioxide. The potential volume of CO2 emission in Taiwan between the years 2007 and 2015 is also estimated according to the information on the government’s long-term development program. Furthermore, the input-output approach and FGP model is constructed to draft future CO2 reduction program for the electric power industry. The program includes fuel substitute of dynamotors and the promotion of electrical efficiency; at the same time, analysis is made on the correlation between CO2 and GDP in this reduction program. The follow factors are substituted into the input-output approach and FGP model constructed in this study. It is carried out that the basic result from the model is economic growth rate 3.51%, CO2 emission 368,207 thousand metric tons and basic simulated result of industry modules. The “other industries” takes the major part of GDP (43.53%), followed by trade business (13.53%), storage and communication (9.10%), electronic engineering (7.09%), and land transportation and its related services (3.32%). These five are fairly important industries that support Taiwan’s economy. It is found that the top five industries that contribute the CO2 emission are land transportation and its related services (19.32%), the department of housing (12.36%), the petrochemical material industry (11.62%), the steel industry (7.72%) and the trade business (5.13%). In the CO2 emission reduction programming, simulated result obtained when operating dynamotors with alternative fuel indicates that when replacing fuel dynamotors with gas dynamotors or zero-emission alternative fuels, the volume of CO2 emission can be decreased efficiently; meanwhile, the average growth of annual GDP increases. Another according to the simulated result of raising electrical efficiency can be decreased the volume of CO2 emission and the average growth of annual GDP increases,too. But when the electrical efficiency raises by 20%, the economic growth of the entire industry reaches its limit value to the most workable program. In this study can be provided to related departments for reference to further map up the reduction of CO2 emissions in electricity industry.
