Age-driven energy poverty in urban household: Evidence from Guangzhou in China

Abstract

Energy poverty occurs when a household cannot fulfill its energy needs. Despite its widespread occurrence, Chinese cities have yet to formally recognize energy poverty as distinct from general poverty at the national level, thereby limiting the effectiveness of countermeasures. Guangzhou, a subtropical first-tier city in China, has a complex population comprising diverse migrants and locals of all ages. This age diversity greatly affects energy demand and poverty sensitivity, so analyzing age's impact on energy poverty is crucial. Thus, this paper surveyed 1072 households in 2020 to measure the extent of energy poverty. The energy poverty rate was found to be 13.85 %. Additionally, a U-shaped relationship was discovered between age and energy poverty, with a turning point at age 44. The adults in Guangzhou who are in energy poverty are not in income poverty. Higher education levels were found to impact energy consumption in households of both younger and older adults. For individuals older than 42—or 46 with a higher education level—the likelihood of experiencing energy poverty gradually decreases with age. Our findings indicate a unique pattern in which both younger and older individuals are susceptible to energy poverty in a humid subtropical climate. To achieve the UN's 2030 clean energy goals, policymakers must focus on tailored skill training, enhanced social welfare, and effective affordable housing policies to alleviate energy poverty.
