运用能源环境理论、多元线性回归分析和主成分分析方法探究西部地区10个省区(市)农户主要生活能源消费特征及碳排放。结果表明:①西部农村生活能源存在明显区域异质性,四川和甘肃生活能源分布特征极明显,贵州、广西和云南生活能源分布特征明显,陕西、青海、重庆、宁夏和新疆生活能源分布特征不明显。②西部农村主要生活能源平均占比排序依次为:太阳能0.29%、沼气0.79%、液化石油气19.95%、煤40.47%、柴草49.16%、电53.24%,使用绿色能源农户占比仅有18.1%,通过发展绿色能源促进“双碳”目标实现任务艰巨。③若西部农村1789万煤用户、4225万柴草用户和1770万煤气、天然气、液化石油气用户转型升级使用绿色能源,每年能节约标准煤约3700万t,减少CO2排放约1亿t。由此可见,生活能源蕴含着巨大碳减排潜力,是不可忽视的“双碳”载体,应进一步加大居民生活能源消费转型升级以此促进“双碳”目标的实现。
Abstract
In order to explore the potential for carbon emission reduction of life energy, this paper conducted an empirical analysis on the spatial structure characteristics of main life energy consumption and carbon emissions in 10 provinces in western China using energy and environment theory, multiple linear regression analysis, and principal component analysis. The results indicate that: ①there is obvious regional heterogeneity in the energy consumption of households in western regions. Sichuan and Gansu have distinct characteristics in the distribution of household energy consumption, while Guizhou, Guangxi, and Yunnan also have noticeable distribution characteristics. The distribution characteristics of household energy consumption are less apparent in Shaanxi, Qinghai, Chongqing, Ningxia, and Xinjiang. ② the average proportion of main life energy is as follows: solar energy 0.29%, biogas 0.79%, liquefied petroleum gas 19.95%, coal 40.47%, firewood 49.16%, and electricity 53.24%, respectively. The percentage of households using green energy is only 18.1%. The task of achieving carbon neutrality goals through the development of green energy is challenging. ③If 17.89 million coal users, 42.25 million firewood users, and 17.7 million gas, natural gas, and liquefied petroleum gas users in the western region transition to the use of green energy, about 37 million tons of standard coal can be saved and more than 100 million tons of CO2 emissions can be reduced every year. The research shows that life energy contains great potential for carbon emission reduction and is a carbon-neutral carrier that cannot be ignored. Therefore, we should further strengthen and accelerate the transformation and upgrading of residents'domestic energy consumption to promote the realization of carbon peaking and neutrality goals.
