Abstract
Due to the climate change caused by environmental pollution, and over consumption of natural resources, renewable energy has become an important issue for most countries. The present study employs a systematic method to assess the performances of different renewable energy used in Taiwan. This method combines Life Cycle Assessment, 3E indicators, and Multi-Criteria Analysis, and objectively evaluates the performance of different kinds of renewable energy. The result indicates that the three major environmental impact issues arising from the development of fuel cells, wind turbines, and PV systems are inhaled in-organics, used of minerals, and the consumption of fossil fuels. From economic view point, the higher capacity of wind turbines, the more efficient in life cycle cost. Based on professional opinions, the outcome of Multi-Criteria Analysis suggests that wind turbine has the greatest integrated performance. The second appears to be PV systems and SOFC. The last place is PEMFC. This research shows that 2500 kW offshore wind turbine is the best choice among several cases to be developed in Taiwan.
