Professor Ning Zhang, a senior fellow from the Department of Land Economy, has published a new article in the prestigious journal PNAS (Proceedings of the National Academy of Sciences of the United States of America). The article examines the total energy cost burden on elderly people across 31 developed countries.

The article is entitled “Higher total energy costs strain elderly, especially low-income, across 31 developed countries”

The abstract reads as follows:

Addressing the total energy cost burden of elderly people is essential for designing equitable and effective energy policies, especially in responding to energy crisis in an aging society. It is due to the double impact of energy price hiking on households – through direct impact on fuel bills and indirect impact on the prices of goods and services consumed. However, while examining the household energy cost burden of elderly, their indirect energy consumption and associated cost burden remain poorly understood. This study quantifies and compares the direct and indirect energy footprints and associated total energy cost burdens for different age groups across 31 developed countries. It reveals that the elderly have larger per capita energy footprints, resulting from higher levels of both direct and indirect energy consumption compared with the younger age groups. More importantly, the elderly, especially the low-income elderly, have the higher total energy cost burden rate. As the share of elderly in the total population rapidly grows in these countries, the larger per capita energy footprint and associated cost burden rate of elderly people would make these aging countries more vulnerable in times of energy crises. It is therefore crucial to develop policies that aim to reduce energy consumption and costs, improve energy efficiency, and support low-income elderly populations. Such policies are necessary to reduce the vulnerability of these aging countries to the energy crisis.
