Abstract
Energy security is an urgent issue to be considered. The world fossil fuel is expected to be exploited in 50 years. Global warming issue is also consequent issue to be recognized. To mitigate these issues, biofuel was assessed its energy efficiency and its environmental performance. Thus to mitigate these issues, this study investigates the two bioethanol promotion strategies to compare and evaluate its environmental performance by life cycle assessment and exergy analysis. Exergy analysis conducted to consider the actual work of thermodynamics for biofuel. The result showed Taiwan has a strong possibility to improve resource management by self producing sugarcane however not producing ethanol. Industrial production of ethanol in Taiwan had shown that the ineffective performance than the Brazilian ethanol production about 1.5 point times of the impact. Importing ethanol from Brazil could sequestrate carbon dioxide (CO2) emission however in the overall emission to the earth is more significant in considering of long transportation. n the bioethanol production, environmental impact from ethanol production stage contributed significant impact in the both two scenarios assessed in this study. Use of fossil energy like diesel, gas and lime strongly impacted health risk to human, and resulting high non-renewable resource consumption and global warming. his study therefore can recommend to Taiwanese policy makers to improve industrial production of ethanol in Taiwan in considering of self production of bioethanol from sugarcane.
