Saving energy is an essential issue in the world to attenuate climate change. To achieve the goal, energy-saving appliances such as refrigerators should be promoted. This study aims to analyze the conditions enabling Japanese households to purchase such appliances, focusing on the relation with preferences for renewable energy as one of the non-monetary incentives.

A conjoint analysis is used. A random parameter logit model and nested logit model are used for estimation. Data were collected through an online questionnaire of the Rakuten Insight service.

Households will purchase energy-saving appliances when renewable energy is used for electricity generation. This implies that households will purchase energy-saving appliances with electric power generators by renewable energy such as solar panels and home micro-wind generators.

The response rate and attributes of respondents and non-respondents are not shown to researchers in the web-questionnaire service.

Promoting energy-saving appliances and renewable energy is essential in Japan (as in other countries) to save energy and to attenuate climate change. Based on the results, both energy-saving appliances and renewable energy will be widely used.

Although many studies have analyzed households’ preferences for energy-saving appliances and the effects of non-monetary incentives, studies that mentioned the relation with preferences for renewable energy are few. This study analyzes the relation and proposes policy recommendations to promote both energy-saving appliances and renewable energy.

The COVID-19 pandemic has caused a dramatic impact on energy supply and demand. It is vital to understand households’ behaviour with regard to energy, particularly during the pandemic, to deploy future sustainable energy systems. This study aims to investigate the nexus of Malaysian households’ energy consumption behaviour in relation to various electrical appliances, their energy-saving appliance purchasing behaviour and their current possession of energy-saving appliances during the pandemic, especially during the lockdown period, from the perspective of the energy cultures framework.

The partial least squares structural equation modelling technique was used to test hypothesised relationships based on the 1,485 pieces of household data collected using an online and physical survey during the lockdown period in Malaysia.

The energy-saving behaviour cultivated due to the impact of the COVID-19 pandemic led to residential customers’ intentions to purchase energy-saving appliances which subsequently led to their current possession of energy-saving appliances. Indeed, energy-saving behaviours in the kitchen, entertainment, office, home lighting and cooling appliances have more than 77.4% influence on their purchasing behaviour. The consumer’s purchase behaviour for energy-saving appliances has a significant, partially mediating influence on the energy-saving behaviour of various electrical appliances and the consumers’ current possession of energy-saving appliances.

This study could be enhanced by improving the sample using a higher-income group and involving other parts of Malaysia such as the southern region. The findings do extend the energy cultures framework by demonstrating the mediating role of households’ energy-saving appliance purchasing behaviour on the relationship between their energy consumption behaviour in relation to various electrical appliances and their current possession of energy-saving appliances.

The results of this study will help develop future action plans for transitioning to energy-saving appliance practices.

This paper examines the effects of the COVID-19 pandemic on future energy efficiency practices in developing countries from the perspective of the energy cultures framework.

Based on climate issues and carbon emissions, this study aims to promote low-carbon consumption and compel consumers to actively shift to energy-saving appliances. In this big data era, online reviews in social and electronic commerce (e-commerce) websites contain valuable product information, which can facilitate firm business strategies and consumer comparison shopping. This study is designed to advance existing research on energy-saving refrigerators by incorporating machine learning models in the analysis of online reviews to provide valuable suggestions to e-commerce platform managers and manufacturers to effectively understand the psychological cognition of consumers.

This study proposes an online e-commerce review mining and management strategy model based on “data acquisition and cleaning, data mining and analysis and strategy formation” through multiple machine learning methods, namely, Bayes networks, support vector machine (SVM), latent Dirichlet allocation (LDA) and importance–performance analysis (IPA), to help managers.

Based on a case study of one of the largest e-commerce platforms in China, this study linguistically analyzes 29,216 online reviews of energy-saving refrigerators. Results indicate that the energy-saving refrigerator features that consumers are generally satisfied with are, in sequential order, logistics, function, price, outlook, after-sales service, brand, quality and space. This study also identifies ten topics with 100 keywords by analyzing 18 different refrigerator models. Finally, based on the IPA, this study allocates different priorities to the features and provides suggestions from the perspective of consumers, the government and manufacturers.

In terms of limitations, future research may focus on the following points. First, the topics identified in this study derive from specific points in time and reviews; thus, the topics may change with the text data. A machine learning-based online review analysis platform could be developed in the future to dynamically improve consumer satisfaction. Moreover, given that consumers' needs may change over time, e-commerce platform types and consumer characteristics, such as user profiles, can be incorporated into the model to effectively analyze trends in consumers' perceived dimensions.

This study fills the gap in previous research in this field, which uses small-sample data for qualitative analysis, while integrating management ideas and proposes an online e-commerce review mining and management strategy model based on machine learning methods. Moreover, this study considers how consumers' emotional and thematic preferences for products affect their purchase decision-making from the perspective of their psychological perception and linguistically analyzes online reviews of energy-saving refrigerators using the proposed mining model. Through the improved IPA model, this study provides optimizing strategies to help e-commerce platform managers and manufacturers.

This study aims to identify the key factors that influence household pro-environmental behaviors (HPEBs) and explore the differences caused by the same influencing factors between household waste management behavior (HWM) and household energy-saving behavior (HES).

A meta-analysis was conducted on 90 articles about HPEBs published between 2009 and 2023 to find the key factors. HPEBs were further categorized into HWM and HES to investigate the difference influenced by the above factors on two behaviors. The correlation coefficient was used as the unified effect size, and the random-effect model was adopted to conduct both main effect and moderating effect tests.

The results showed that attitude, subjective norms, and perceived behavioral control all positively influenced intention and HPEBs, but their effects were stronger on intention than on HPEBs. Intention was found to be the strongest predictor of HPEBs. Subjective norms were found to have a more positive effect on HES compared to HWM, while habits had a more positive effect on HWM. Furthermore, household size was negatively correlated with HWM but positively correlated with HES.

The same variables have different influences on HWM and HES. These results can help develop targeted incentives to increase the adoption of HPEBs, ultimately reducing household energy consumption and greenhouse gas emissions and contributing to the mitigation of global warming.

The escalating levels of greenhouse gas emissions have become a growing global concern, with household energy consumption emerging as a significant contributor. To develop effective public policies, it is crucial to understand the energy-saving behavior of households. This study delves into the determinants of energy-saving practices in a developing country.

The authors chose a multivariate probit model, as it allowed to look after possible correlations among seven energy-saving practices within households.

The findings underscore the significant influence of sociodemographic variables, such as gender, civil status, income and education, on energy-saving practices. Furthermore, the authors discovered that households where the head actively volunteers in social organizations are more likely to adopt energy-saving behaviors. Additionally, internet access positively contributes to pro-environmental behavior. This research reveals that certain energy-saving practices are interconnected, acting as complements or substitutes.

Recommendations for public policy include prioritizing education in rural areas to boost energy-saving practices, improving internet access in nonurban regions and promoting citizen involvement in social organizations to enhance environmental awareness and encourage energy-saving behavior. The authors contribute to literature evidencing that certain energy-saving practices are not independent of each other, they are rather complementary and, in some cases, substitutes.

Recommendations for public policy include prioritizing education in rural areas to boost energy-saving practices, improving Internet access in nonurban regions and promoting citizen involvement in social organizations to enhance environmental awareness and encourage energy-saving behavior.

Previous studies have overlooked these interdependencies, highlighting the necessity of a system of equations to yield more efficient estimates by considering correlations between error terms.

Given the rapid increase in energy consumption in the residential sector in Jordan recently, the question of how to promote energy-saving behavior in Jordanian households is an emerging topic that is receiving increasing attention from scholars and academics. Generally, there is an unresolved paradox in the literature concerning electricity-saving behaviors. On one hand, numerous studies highlight energy-saving behaviors. On the other hand, recent research indicates the presence of significant untapped potential in electricity-saving behaviors. Therefore, it is useful to revisit the construct of these behaviors qualitatively to expand understanding. The study aimed to provide a better understanding of electricity energy-saving behaviors in terms of its motivations, barriers and support mechanisms from household heads' or household members' perspectives

Qualitative study in a sample of households in north Jordan was conducted in the Irbid province using grounded theory methodology. The analysis of qualitative data involved coding, followed by the integration of codes into more comprehensive categories and themes and interpreting the findings.

The results identify the motivations for households to save energy, the main barriers to indulging in electricity energy-saving behaviors, and the main support mechanisms and perceived support of electricity energy-saving behaviors

The findings bear significant implications for targeted interventions in the study area, improving motivations and addressing local barriers and can inform future policy issues by tailoring initiatives to the specific context.

This study is distinguished by being the first study that specializes in electricity energy-saving behavior of households in Jordan, using new methodology and techniques (qualitative survey).

Hong Kong has experienced an average annual growth in final energy consumption of 4.7 per cent over the last ten years. An initiative being undertaken by a small number of government and commercial organisations is to limit their own consumption of electricity through performance contracting. Performance contracting is essentially a partnering process, where a client organisation partners with an energy management firm to identify and achieve energy savings for the client organisation. The research undertaken for this project has identified a number of factors that are considered to affect the success of performance contracting in Hong Kong. In a survey of practitioners, who have experience of performance contracting, some of the key benefits of this approach identified include the fact that there are substantial energy cost savings to be made. These savings are guaranteed by the partnering energy saving company and there are overall improved operational and plant efficiency gains. Key requirements for the success of such schemes include the setting‐up of an agreed energy baseline against which to measure results and human factors such as commitment to the enterprise at all levels of the organisation and trust between the co‐operating organisations. The paper expands the discussion on the benefits, obstacles and necessary ingredients for performance contracting that are likely to be applicable not just to Hong Kong but to the successful implementation of any such scheme.

Based on stimulus-organism-response (S-O-R) theory and a serial multiple mediation model, this study aims to examine the relationships between cultural values and energy-saving behaviors as well as the mediation mechanisms of attitudes towards energy-saving and energy-saving intentions underlying these links.

A sample of 1,514 urban residents collected in five big cities in Vietnam and Structural Equation Modeling were employed to test the hypothesized model.

The study yields that energy-saving behaviors can be directly influenced by long-term orientation, but not by collectivism, while both collectivism and long-term orientation work as stimulus which immediately inspire attitude towards energy-savings and energy-saving intentions. Interestingly, attitudes towards energy-saving and energy-saving intentions not only serve as the most crucial predictors of entrepreneurial behaviors but also cooperate a serial mediation role in the impacts of cultural values on energy-saving behaviors.

The findings of this research can be valuable for policymakers to inspire urban residents’ energy conservation behavior for sustainable development goals.

This study contributes to the pro-environment literature by adopting the S-O-R theory to investigate the impacts of cultural values on the energy-saving attitude-intention-behavior relationships, explain the underlying mediation mechanism of energy-saving attitudes and intentions in transferring the influences of cultural values on energy-saving behaviors, and bridge the attitude-intention-behavior gap in the energy-saving research.

There is an unresolved paradox concerning electricity energy-saving behaviour. On one hand, there are many studies on energy-saving behaviours and on the other hand, recent research stresses that there exists large amount untapped potential in terms electricity energy-saving behaviours. Therefore, it becomes pertinent to revisit the construct of electricity energy-saving behaviours qualitatively to enlarge the spectrum of understanding. The purpose of this paper is to answer the research question why do not customers care about electricity energy-saving behaviours.

A qualitative study is undertaken in Western India using grounded theory methodology. The basic steps in the analysis of qualitative data consist of coding the data, combining the codes into broader categories and themes, and interpreting the results.

The study identifies seven categories of determinants of electricity energy-saving behaviours. Policy implications and limitations of the study are discussed along with areas of future research directions.

This is the first study to unearth the dimensions of electricity energy-saving behaviour.

Energy-saving behavior of individuals is essential to minimize energy use and reduce the emission of toxic gases. This study's actual focus is to find out the determinants of the energy-saving behavior of individuals in the workplace.

As a theoretical research model, the extended theory of planned behavior (TPB) has been used to analyze the determinants of energy-saving intentions. A survey method is used to collect 289 valid data, and structural equation modeling (SEM) is used to analyze the data.

The final result shows that the variables attitude at home, subjective norm (SN) and descriptive norms positively impact intention to save energy at the workplace. In contrast, the construct attitude and perceived behavior control is insignificant in this research. On the other hand, the personal moral norm (PMN) is a powerful predictor of individual energy-saving intentions at the workplace.

This research provides insights that will help the organizations understand the behavior of individuals at the workplace for energy-saving intentions to formulate such policies that will enhance individuals' practice for energy savings.
