This work explores the consequences that different energy poverty definitions and measures might have for the identification of the energy poor. Using the 2017 National Survey of Public Energy Perception applied to a sample of 3,500 households in Chile, we compare the respective identification outcomes of applying the ten percent rule index (TPRI) and our proposed Perception-based Multidimensional Energy Poverty Index (PMEPI) against the monetary poverty identification outcome. Based on the findings of this comparation, we propose a classification system of first- and second-order energy poverty measures depending on their degree of association with income poverty (as indicated by the distribution of the income poverty status of households). A first-order energy poverty measure exhibits a high association level with income poverty. By contrast, a second-order energy poverty measure shows a low level of association. Coincidentally, our TPRI (first-order) and PMEPI (second-order) estimates each classify 15.5% of the population as energy poor. However, the adoption of any particular definition necessarily narrows the resulting set of energy-poor households in a way that is distinct from other definitions, meaning that the use of multiple definitions produces diverging energy poverty rankings across the territory. Moreover, the TPRI neglects supply-side constraints captured by the PMEPI. Consequently, when identifying and targeting the energy poor, first- and second-order definitions should not be used as substitutes but rather as complements. This fact needs to be considered in the energy policy debate on the implementation of energy poverty alleviation actions.

这项工作探讨了不同的能源贫困定义和措施可能对识别能源贫困者产生的后果。使用适用于智利3,500户样本的2017年《全国公共能源感知调查》，我们比较了应用10％规则指数（TPRI）和我们提议的基于感知的多维能源贫困指数（PMEPI）的各自识别结果。货币贫困识别结果。基于这种比较的结果，我们根据能源贫困与收入贫困的关联程度（由家庭收入贫困状况的分布表明），提出了一阶和二阶能源贫困度量的分类系统。一阶能源贫困测度显示出与收入贫困的高度关联。相比之下，二阶能源贫困测度显示出较低的关联度。巧合的是，我们的TPRI（一阶）和PMEPI（二阶）估计分别将15.5％的人口归为能源匮乏。但是，采用任何特定的定义必然会以与其他定义不同的方式缩小所产生的能源贫乏家庭的范围，这意味着使用多个定义会在整个国家范围内产生不同的能源贫困等级。此外，TPRI忽略了PMEPI捕获的供应方约束。因此，在识别和确定能源贫乏的人时，一阶和二阶定义不应用作替代，而应作为补充。在有关执行能源扶贫行动的能源政策辩论中需要考虑这一事实。
