碩士 / 國立臺北大學 / 自然資源與環境管理研究所 / 101 / Taiwan is a country highly dependent on energy imports. While there is still growing demand for energy, Taiwan also faces two important issues. They are energy depletion and climate change caused by use of fossil fuels that produce large amount of greenhouse gas emissions. Countries should actively develop renewable energy since renewable energy is clean and low pollution, and wind power is one of the renewable energy options. However, land can be developed for wind power sites is limited and land acquisition is difficult. Moreover, people tends to against wind power because of the noise and shadow flicker of wind turbine. Therefore, promoting the development of offshore wind power systems is a good alternative. This study discusses the establishment of offshore wind power system, at the same time explores its environmental assessment and conducts its life cycle assessment.
The first step for Taiwan to build offshore wind power system is to carry out environmental impact assessment. This study considers the environmental impact assessment of building offshore wind power generation system as the following. An overall and systematic survey and forecast of the current environmental conditions, factors may affect the environment, and possible future environmental impact which should be conducted by the government when formulating policy options (program) for the development of land for non-specific behavior. Accordingly, this study investigates environmental issues that will occur when establishing offshore wind power, including typhoons, earthquakes, Chinese white dolphin, and artificial islands.
The Life Cycle Assessment with respect to the offshore wind power systems installation in Taiwan shows that 2.030-3.226g of steel, 0.77-0.122g of stainless steel, 0.121-0.192g of iron, 0.125-0.199g of glass fibers, 0.038-0.060g of plastic, 0.045-0.074g of Pb, 0.033-0.053g of copper, 0.027-0.043g of aluminum, 0.057-0.090g of zinc, 0.026-0.043g of concrete are needed per kWh power generated by wind. The energy consumption of offshore wind power system is about 83.11-135.36kJ/kWh and CO2 emissions is about 3.58-5.64g/kWh. The energy payback time is about 0.18-0.29 years and emission payback time is about 0.13-0.212 years.
