Contrastive Analysis between Wind Power Generation and Coal Generation on The Environmental Impact Assessment
(0) Wind power is an important type of renewable energy sources.In this passage we will apply Life Cycle Assessment to analyze the four stages of wind power generation, which are production of raw materials, transportation, build-operate process of wind plants and demolition stages, calculate the energy consumption and the environmental impact, set a contrastive analysis between coal-fired power plants and wind power plants.We will take WangHaiSi Wind Plant in Faku, Shenyang as an example to show the difference between the two ways of getting power.The analysis shows that: in comparison with coal-fired generation, wind power generation saves more energy and reduces emissions of pollutants markedly; the main energy consumption comes from production of raw materials, which takes 79.3% of the total energy consumption throughout the life cycle.In the meantime, the large amount of ecological resources consumption from construction, operation and maintenance of wind plants leads to mass emission of carbon dioxide and sulfur dioxide, which respectively take 67.3% and 96.6% of total emissions.Besides, wind generation only accounts for 0.93%, 0.89% and 2.72% of energy consumption, global warming potential (GWP) and acid potential (AP) of coal-fired power generation.Thus, it proved that wind power generation has lesser impacts on environment than coal-fired power generation.However, it is still of great necessity to strengthen the environmental protection measures to reduce the consumption and destroy of ecologic resources.
