This paper investigates the impact of rapid demographic changes in Korea on residential electricity use, finding that household differentiation has increased per capita electricity use while an ageing population has a negative impact. Given the persistently low fertility in Korea, household differentiation is projected to exacerbate this impact.
This paper investigates the impact of rapid demographic changes in Korea on residential electricity use. Demographic changes in Korea are characterized as i) household differentiation (increasing number of nuclear (one or two-person) households despite the stagnant population growth) and ii) unprecedentedly fast-paced population ageing. Per capita electricity demand is estimated using a dynamic panel model with the system GMM. Results show that household differentiation has increased per capita electricity use in both shortand long-run; the ageing population has the negative impact on per capita electricity consumption. The impact of household differentiation, which is projected to be accelerated with the persistent low fertility in Korea, is substantial. Nuclear households use more electricity per person, but pay less electricity bill since Korea has the progressive electric billing system. Stakeholders and industry analysts should consider household differentiation to prepare the long-run electricity provision policy as well as the proper billing system. Lessons from the study have wider policy implications in other developed countries with the similar demographic changes. (c) 2021 Elsevier B.V. All rights reserved.
