Income-based energy poverty metrics miss people’s behavior patterns, particularly those who reduce their energy consumption to limit financial stress. Using a residential electricity consumption dataset, we determine the outdoor temperature at which households start using home cooling systems. Using this inflection temperature, we calculate the relative energy poverty within a region, which we define as the energy equity gap. In our study region, we find that the energy equity gap between low and high-income groups ranges from 4.7°F to 7.5°F. In 2015-2016, within our population of 4,577 households, we found 86 energy-poor and 214 energy-insecure, meaning they are at risk of heat-related illness and death. In contrast, the traditional income-based energy poverty metric identified just 141 households as energy insecure. Only three households were defined as energy-poor or energy-insecure by both our temperature-based measure and the traditional income-based measure. This minimal overlap shows the value of considering consumer behavior when identifying energy poverty and energy insecurity.
