“…As with other literature, they suggest this could be due to changes in water use behavior and practices relating to COVID-19 and its impact on everyday life. They highlight similar reasons for this change as Kim et al (2021), suggesting the movement of water use into the home as a reason for this increase but go into more detail. They hypothesize that increased intensity of practices due to increased personal hygiene, lower efficiency of household micro components (e.g., individual hand washing of dishes as opposed to canteen style cleaning) as well as new practices associated with warmer weather (e.g., the use of gardens as sites of pleasure, socializing, and a space for new hobbies in lockdown) drove these increases in domestic water use.…”

COVID‐19 has had unprecedented impacts across the international community, with complex and far‐reaching consequences. Measures to prevent transmission have led to substantial changes to everyday life, with lockdowns, stay‐at‐home orders and guidance leading to an increase in people staying indoors. This movement of activity had profound impacts on daily practices, affecting the consumption of resources including water. Likewise, Water, Sanitation and Hygiene (WASH) practices and infrastructure are crucial tools for the management of disease. Therefore, this review seeks to assess the current literature on the impact of COVID‐19 on domestic water use. A web‐based rapid evidence review was undertaken to assess and synthesize the theories, methods and empirical evidence emerging across a multidisciplinary body of research to understand how COVID‐19 effects everyday water use. Key themes around increased water consumption and changing daily consumption patterns emerged. There was a distinct lack of social science concepts and methodologies in use to understand changing water demand, and the methodological focus was largely quantitative. Key insights and reflections were lacking as a result, for example, there was little research on how the water‐related practices, consumption, and demand patterns differed among households. This article makes the case for further qualitative and mixed‐method research using social theories, illustrating how social practice theories, as one example, contribute to understanding the dynamics of everyday life during the pandemic. This research would generate deeper understandings of the impacts of COVID‐19 on domestic water use as well as an evaluation of the implications these findings could have post‐pandemic.

“…The hours of maximum hot water draw of residents in Seoul (South Korea) can be cited as an example. The draw was lower from 04:00 a.m. to 10:00 a.m. compared to the time before the pandemic, but there was a definite increase in water consumption from 11:00 a.m. to 8:00 p.m. A dependency was also observed between the average number of actively infected persons in a given month and changes in hot water consumption [55].…”

Indirect Impact of the COVID-19 Pandemic on Natural Gas Consumption by Commercial Consumers in a Selected City in Poland

et al. 2022

In March 2020, a lockdown was imposed due to a global pandemic, which contributed to changes in the structure of the consumption of natural gas. Consumption in the industry and the power sector decreased while household consumption increased. There was also a noticeable decrease in natural gas consumption by commercial consumers. Based on collected data, such as temperature, wind strength, duration of weather events, and information about weather conditions on preceding days, models for forecasting gas consumption by commercial consumers (hotels, restaurants, and businesses) were designed, and the best model for determining the impact of the lockdown on gas consumption by the above-mentioned consumers was determined using the MAPE (mean absolute percentage error). The best model of artificial neural networks (ANN) gave a 2.17% MAPE error. The study found a significant decrease in gas consumption by commercial customers during the first lockdown period.

“…The results show that the decrease in consumption will be 8-10% and 6% in the upcoming two years. Kim et al [104] applied a machine learning model with artificial neural networks for the prediction of hot water demand in the residential sector in South Korea. The authors determined the changes in the increase in hot water demand by about 8-16%.…”

In order to control the COVID-19 pandemic, the governments of the world started to implement measures regarding social distance and social contacts, including closures of cities, work and study relocations, and work suspension. The epidemical situation and the lockdown of the economy by governments in various countries caused changes in production, changes in the habits of energy consumers and other energy-related changes. This article analyses the impact of the global pandemic on the energy sector and the relationship with the progress to the sustainability of the energy sector. The systematic literature review was performed in the Web of Science (WoS) database. The research follows recommendations of the SALSA (Search, Appraisal, Synthesis and Analysis) and PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) approaches. A total of 113 relevant articles were selected for the analysis. All selected articles were categorized according to their application and impact areas. The five main impact areas of the COVID-19 pandemic to the sustainability of the energy sector were identified: consumption and energy demand; air pollution; investments in renewable energy; energy poverty; and energy system flexibility. Based on the current research findings and perception of the problem, the main insights for future research in the field are provided.
