Trends in Research on Energy Efficiency in Appliances and Correlations with Energy Policies

Abstract

According to the Intergovernmental Panel on Climate Change (IPCC) 5th Assessment report, energy-efficient appliances can reduce global electricity consumption even though there is an expected increase in the number and ownership of appliances. The International Energy Agency (IEA) expects a high increase in energy efficiency in traditional appliances (refrigerators, washing machines, television, etc.), and in the number of new appliances installed (also called plug loads). The bibliometric study of publications related to energy-efficient appliances carried out in this paper shows that research on this topic is growing in developed regions (North America and Europe) and even more in some developing regions (Asia Pacific) with a high emphasis on China and India. The results indicate that, in general, policies are always implemented before the core of publications on the topic, with time spans ranging from 3 to 30 years. However, the trend seems to be changing with publications related to new appliances where the core research happens shortly after or in parallel to the establishment of policies.

“…The first factor being the need of deep and often prolonged overhaul of energetic infrastructure. This, in turn, requires a substantial amount of capital, as well as well-planned, effective energetic policies, realized in a consistent manner (Zhang and Wang, 2022;Vérez et al, 2022).…”

Combining CAD Modeling and Simulation of Energy Performance Data for the Retrofit of Public Buildings

“…The global energy sector is facing increasing challenges, including reducing the environmental impact of buildings, which is now inextricably linked to the pollution resulting from the indiscriminate use of non-renewable energy sources [1][2][3]. Many buildings in the European Union (EU) still do not meet the energy efficiency standards required to move to a sustainable consumption pattern [4,5]. Specific measures must therefore be taken to meet these challenges, proposing intervention scenarios aimed at massive and adequate use of renewable energy sources.…”

“…The third phase is the evaluation of the potential of each intervention, while the fourth phase is dedicated to the implementation of the renovation solutions, which are finally validated by the results in the fifth phase [11]. Numerous studies already provide tools and context for reducing energy consumption around the world [3][4][5][6][7][8][9][10][11][12][13][14]. Retrofitting existing structures can significantly reduce energy consumption and greenhouse gas emissions worldwide.…”

“…Therefore, they propose a machine learning approach to indicate optional interventions. Numerous studies already provide tools and context for reducing energy consumption around the world [3][4][5][6][7][8][9][10][11][12][13][14]. Retrofitting existing structures can significantly reduce energy consumption and greenhouse gas emissions worldwide.…”

The Study of Promising Research Areas on the Petroleum Science Topic via Bibliometric Analysis of the 2018-2021 Publications in the Journal of Petroleum Science and Engineering

“…The relationship of policy decisions and implementation, as reflected in scholarly publications, is discussed in [11] which argues that the bibliometric analysis of publications on the topic of energy efficient appliances shows that policies are usually implemented before major publications on the topic, with time lags ranging from 3 to 30 years. Nevertheless, this trend is changing with the appearance of publications about new devices that appear shortly after or parallel to the creation of the policy.…”
