能源转型视域下“零碳乡村”的可行性和环保性——以陕西关中C县F村为例

    Feasibility and Environmental Protection of “Zero Carbon Rural” from the Perspective of Energy Transition—Take F Village in Middle Area of Shaanxi Province as an Example

    • 摘要: 农业、农村、农民问题关系着经济社会发展的全局,农村能源转型是推动社会可持续发展的重要支点。以陕西关中C县F村生活能源消费和碳排放为切入点,构建起基于“碳源—碳汇”平衡及“碳中和”评价框架的“零碳乡村”实践理念,通过对427户农户家庭进行问卷调查和入户走访,掌握第一手数据及资料,对F村能源消费结构、碳排放量、分布式可再生能源利用方式进行详细分析。结果表明:目前该村农户的炊事、取暖等生活能源仍以煤炭、秸杆、柴薪等固体燃料为主,可再生清洁能源使用量几乎为零;农户环保意识强但环保常识匮乏;结合关中地区资源禀赋特性认为,利用分布式光伏发电替代传统能源具有可行性,户均安装分布式光伏规模2.34千瓦即可实现清洁能源替代和零碳化,户均安装分布式光伏5千瓦,不仅能实现能源自给,还有具大的收益空间;F村商品性能源碳排放比例高于非商品性能源,其中,散煤燃烧碳排放占比在47%~50%之间,用分布式光伏发电代替传统的秸杆、煤炭、柴薪、煤电等,可为环境减排1 225.6吨~1 436吨的CO2,环保性能突出。

       

      Abstract: The problems of agriculture, rural areas and farmers are related to the overall situation of economic and social development, and rural energy transition is an important fulcrum for promoting sustainable social development. Based on energy consumption and carbon emissions of F Village in central Shaanxi Province, a practical concept of "zero-carbon village" was constructed based on "carbon source-carbon sink" balance and"carbon neutralization" evaluation framework. Through questionnaires and household visits to 427 households of farmers, first-hand data and information were grasped, and the energy consumption structure of F Village was studied. Carbon emissions and the use of distributed renewable energy were analyzed in detail. The results show that households' cooking and heating are still dominated by solid fuels such as coal, straw and firewood, and they rarely or never use clean energy; households' awareness of environmental protection is strong, but the knowledge of environmental protection is scarce; considering the resource endowment characteristics of the middle area in Shaanxi province, it is believed that it is possible to use distributed photovoltaic power generation to replace traditional energy sources. As a result, households can achieve clean energy substitution and zero-carbon by installing distributed photovoltaic scale of 2.34 kW, if when households install distributed photovoltaic of 5 kW, they can not only realize energy self-sufficiency, but also have a large profit margin. The carbon emission ratio of commercial energy in F Village is higher than that of non-commercial energy, among which the carbon emission from loose coal combustion accounts for 47%~50%. The use of distributed photovoltaic power generation instead of traditional straw, coal, firewood, coal power etc. can reduce the environmental emissions of 1 225.6~1 436 tons of carbon dioxide, with outstanding environmental protection performance.
