碩士 / 國立臺北大學 / 自然資源與環境管理研究所在職專班 / 96 / The global awareness respects to climate changes, soaring oil price, and energy crisis, etc. has arose in decades. The persistent anthropogenic activities burden the environment and cause the shortages of energy. To mitigate environmental damages and establish substantial development of mankind, scientists and governments devote themselves to seeking clean and renewable energies. CO2 and hazardous substances emitted from fossil fuel combustion have direct impacts on global warming and environmental pollution issue; therefore, the developments of alternative energy have become an imperative issue for Taiwan.
This research aims to assess the most feasible energy crop for bio-ethanol fuel productions and analyze cost-effectiveness of the following alternatives (1) importing bio-ethanol fuel directly；(2) importing feedstock to produce bio-ethanol fuel；(3) planting energy crops to produce bio-ethanol fuel in Taiwan. Regression analyses of motor gasoline demanding models in Taiwan followed by the influences of gasohol strategies, such as planting energy crops to produce bio-ethanol fuel or importing bio-ethanol fuel to promote E3, enable Taiwan government to forecast the future motor gasoline demands.
The result shows that sugarcane and sweet potato are two feasible feedstock of bio-ethanol fuel production in Taiwan. The result also shows that the most cost-effective alternatives of bio-ethanol development in Taiwan are importing bio-ethanol fuel directly and production of bio-ethanol fuel from sweet potato with foreign manufacturing processes.
In addition, this research adopts regression analysis to construct future motor gasoline demanding model in Taiwan. According to the predicted motor gasoline demanding model, two scenarios are applied to evaluate the promotion results of E3 gasohol: (1) planting energy crops to produce bio-ethanol fuel of from 2008 to 2011; (2) importing bio-ethanol fuel from 2008 to 2011. The result of simulation shows that no import of bio-ethanol fuel is necessary for the fulfillment of the policy target set by the government; however, the limitation of land availability and insufficient subsidy from government result in higher bio-ethanol fuel production cost. Hence, planting energy crops to produce bio-ethanol fuel shows no economic incentives for the native farmers. Although bio-ethanol fuel is less economical attractive, the applications of bio-ethanol fuel certainly bring benefits to eco-system, landscape, and CO2 emission reduction.
