Abstract：This paper brought forward a detailed method of quantifying life-cycle energy consumption and CO2 emissions of wind power technology. Using case data from a Shanghai wind farm, the results show that energy consumption and CO2 emissions from the stage of wind turbine production are the highest among all stages of the life cycle, and the shares are 68.23% and 67.18% respectively. Uncertainty analysis also implies that the comprehensive energy consumption of steel production is the most sensitive parameter to affect the final results. The life-cycle energy intensity and CO2 intensity of wind farm are respectively 3.24gce/(kW?h) and 9.47g/(kW?h), which is obviously lower than the corresponding values [330gce/(kW?h) and 915g/(kW?h)] for a 300MW coal-fired generating unit. For a 50 MW wind farm which reaches its end of life (20 years), it can altogether reduce 2.34 million tons of CO2 compared with a 300 MW coal-fired generating unit.
