Three kinds of turbines (Vestas V-47:660kW, Enercon E-40:600kW, Vestas V-66:1.75MW) were installed on three selected sites (Mailiao, Jhongtun, Chunfong) as wind power plants for electricity generation on an island. However, such power plants including turbines in establishment and operation during entire life cycle are bound to consume energy and produce carbon emission, causing environmental problems. Therefore, the purpose of the present study is to evaluate the effects of three wind power plants on the environment during their entire life cycle. This paper made the calculations of carbon emissions of three wind power plants, and compared and discussed the occupied shares of each primary energy input in manufacture, construction, operation and disposal phases using the methods of mathematics and materials input-output life cycle assessment. The results show that the CO₂ emission factor of three systems was on average 3.9 g/kWh for the whole life cycle. The average CO₂ emission intensity of all raw materials was 1.35 kg/kg. The occupied share of CO₂ emissions in manufacturing, construction, and decommissioning phases was 44%, 16%, and 40% respectively. The primary energy input intensity was on average 0.0625 MJ/kWh of three systems for whole life cycle. The average energy input intensity of three systems was 21.48 MJ/kg. The combined CO₂ emission intensity of all steel materials was 1.98 kg/kg. The demands for materials and energy inputs, and carbon emissions are positively related to the rated power value of a wind turbine. Wind power has a priority to produce clean energy, and can significantly decrease CO₂ emissions.

在选定的三个地点（麦iao，中屯，春风）安装了三种涡轮机（Vestas V-47：660kW，Enercon E-40：600kW，Vestas V-66：1.75MW）作为岛上发电的风力发电厂。但是，这样的包括涡轮机在内的整个生命周期中的运转中的发电厂必然消耗能量并产生碳排放，从而引起环境问题。因此，本研究的目的是评估三个风力发电厂在其整个生命周期中对环境的影响。本文对三个风力发电厂的碳排放进行了计算，并使用数学和材料投入产出生命周期评估方法，比较并讨论了在制造，建造，运营和处置阶段每个一次能源投入的占有份额。在整个生命周期中，三个系统的₂排放因子平均为3.9 g / kWh。所有原料的平均CO ₂排放强度为1.35 kg / kg。在制造，建筑和退役阶段，CO ₂排放所占的份额分别为44％，16％和40％。在整个生命周期中，三个系统的一次能源输入强度平均为0.0625 MJ / kWh。三个系统的平均能量输入强度为21.48 MJ / kg。所有钢材的总CO ₂排放强度为1.98 kg / kg。对材料和能量输入以及碳排放的需求与风力涡轮机的额定功率值成正相关。风力发电是生产清洁能源的重中之重，可以显着降低二氧化碳排放量₂排放。
