Abstract
The emergence of the COVID-19 (coronavirus disease of 2019) pandemic in 2020 and the ensuing state of emergency issued by the Japanese government, which was enforced from April 6 to May 25, 2020, changed our collective lifestyle dramatically. An increase in time spent at home resulted in a change in energy consumption structure. This study aimed to estimate the change in energy consumption at home during and after the state of emergency in Kobe, Japan. Six types of household energy consumption models were created based on the age of the head of household, the number of household members, and the floor area. The usage time and energy consumption of consumer durables were estimated for each model type. The model analysis results revealed that energy consumption during and after the state of emergency increased by 4.2% and 3.7%, respectively, compared to consumption before the state of emergency.
期刊介绍：
The Journal of Sustainable Development of Energy, Water and Environment Systems – JSDEWES is an international journal dedicated to the improvement and dissemination of knowledge on methods, policies and technologies for increasing the sustainability of development by de-coupling growth from natural resources and replacing them with knowledge based economy, taking into account its economic, environmental and social pillars, as well as methods for assessing and measuring sustainability of development, regarding energy, transport, water, environment and food production systems and their many combinations.
