“…Coal-fired power plant cogeneration can effectively reduce costs in the centralized heat supply sector while meeting the demand for heat to a greater extent (Du et al, 2023). In addition to improving the efficiency of energy utilization and taking measures such as purifying emissions, it is also important to promote the development of clean heating and heat sources such Frontiers in Energy Research frontiersin.org as electric heating, air source heat pumps and water source heat pumps (Amirkhizi and Jensen, 2020). The influence of hot summer weather has increased the intensity of use of cooling equipment such as air conditioners in southern regions and is more concentrated in economically developed regions such as the southeast coast.…”

Rapidly increasing household energy consumption poses significant challenges to global warming mitigation and the transition to low-carbon economies, particularly in China. This paper addresses this issue by introducing a comprehensive segmentation model which effectively subdivides household energy usage into five end-uses: cooking/hot water, heating, cooling, lighting, and power. The segmentation model uncovers compelling insights into urban end-use energy consumption patterns across China and variations among provinces. We observe a consistent increase in urban household end-use energy consumption and per capita energy consumption levels over the past decade. Heating and cooking/hot water emerge as the dominant contributors to household energy consumption, accounting for 26% and 40% of the total, respectively. Furthermore, it is found that higher levels of urbanization and improved living conditions are positively correlated with increased power energy consumption. The declining number of household members, primarily due to the prevalence of nuclear families, has resulted in higher energy end-use, particularly in both developed and underdeveloped economic areas. This paper serves as a valuable foundation for understanding and quantifying household end-use energy consumption. The findings contribute to a more comprehensive understanding of energy consumption patterns, facilitating a cleaner and more sustainable transformation of energy consumption structures.

“…El remplazo de los equipos convencionales de calefacción/refrigeración por bombas de calor electricadas con energías renovables es también un tema muy desarrollado por la comunidad cientíca, Amirkhiz et al, 2020 [42], presentó un estudio en Dinamarca donde usaba bombas de calor híbridas con una caldera de gas. El programa de funcionamiento óptimo demostró, que el uso de la caldera correspondía al 24 % y el resto con bomba de calor eléctrica generada a partir del viento.…”
