Pollution Reduction Effect of Rural Integrated Energy System Oriented to Low-Carbon Transformation

with the gradual decline of environmental air quality in China, the traditional way of energy use in rural areas has been gradually outlawed due to low energy consumption and high pollution. It is urgent to find a low-carbon and environmentally friendly energy supply method suitable for rural areas. Based on low carbon environmental protection as the goal, this paper analyzed the natural resources in the rural areas and proposed a comprehensive energy system suitable to rural area, which composed of the photo voltaic, wind power, ground source heat pump, straw curing fuel for rural energy, can make full use of abundant biomass and idle land in rural area and satisfy rural residents’ demand for cold, heat, electricity. With the pollution emission factor model as the main calculation reference, this paper studies the pollution emission of energy system, and initially adopts the full life cycle method to calculate the pollution emission of photo voltaic and wind power equipment. Considering the flexible consumption of users and the initiative of operators, the capacity of energy supply equipment is selected with the goal of low carbon emission reduction and considering economic constraints. Taking full account of regional differences, the low-carbon emission reduction effects of three different energy supply modes are compared. Taking a rural area in shandong province as an example, the proportion of CO
