The purpose of this paper is to identify the barriers to consumers’ intention to purchase energy efficient appliances. It uses multiple regression analysis to predict the factors that deter consumers’ purchase intention.

Five barriers to consumers’ intention to purchase energy efficient appliances were identified through an exhaustive literature survey. Data were gathered from 300 respondents from Pune city from the state of Maharashtra in India through a survey. The items were measured on a five-point Likert scale. Validity and reliability of the scale were established. Multiple regression analysis was conducted to predict consumers’ intention to purchase energy efficient appliances based on factors identified.

Findings revealed that some degree of uncertainty was associated with energy efficient appliance purchase. In addition to possessing lower degrees of awareness on energy efficient appliances, consumers tend to disbelieve claims made on labels of energy efficient appliances. Consumers also feel inconvenience in identifying these appliances, spending time to know about them and paying the price to purchase them. Hence, the factors – scepticism towards label claims and perceived personal inconvenience – were found to have negative impact on consumers’ purchase intention. Societal norm was found to have a positive impact on consumers’ purchase intention. Interestingly, price sensitivity and perceived product risk (which were expected to have a negative relationship with consumers’ purchase intention) displayed a positive relationship.

The model proposed here is based on the researcher’s identification of the barriers. There might have been unidentified barriers that were not considered. The research does not account for manufacturing or policy-based issues that might also pose as barriers. The study encourages marketers to re-examine marketing and communication policies associated with the sale of energy efficient appliances.

The paper provides insights into the external barriers faced by consumers while purchasing an energy efficient appliance. This research enables managers to understand consumer’s preference for conventional products over energy efficient ones. It attempts to check the presence of barriers to energy efficient appliances, identified from literature in a tier 1 city of India. Tier 1 city is the city with population greater than 1,00,000 as per 2001 census of India.

The purpose of this paper is to investigate how consumers’ altruistic values influence their personal norms, environmental attitudes, subjective norms and perceived barriers, all of which in turn influence their pro-environmental behaviour (i.e. the purchase of energy efficient household appliances).

This research follows a hypothetic-deductive approach. A unique conceptual model examines the role of consumers’ altruistic values in relation to their environmentally responsible purchase behaviour. Structured questionnaires were administered to randomly selected Vietnamese consumers who visited busy electronics and appliance specialist stores, which yielded 682 usable responses.

Structural equation modelling revealed that consumers’ altruistic values tend to positively influence their personal norms, environmental attitudes, subjective norms and mitigate their perceived barriers in relation to the purchase of energy efficient appliances.

Marketers, policymakers and sustainability campaigners should develop relevant communication and education programmes that emphasise the importance of purchasing energy efficient appliances for the environment and society, arousing consumers’ sense of moral obligation and societal responsibility to purchase such products. They should also provide a convenient and easily accessible shopping environment for consumers.

This research makes an important contribution by presenting and testing a new altruistic-values-based model that seeks to understand consumers’ environmentally responsible purchase behaviour. This model could serve as a blueprint for future studies in the domain of pro-environmental behaviour, especially those in emerging markets.

Electricity savings from energy-efficient appliances (EEAs) may have a significant impact on reducing global warming. There are several barriers confronted by EEAs, which have lowered their acceptance rate. The current study aims to identify and highlight key barriers to strengthening domestic sector adoption of EEAs in developing countries.

In the current study, 13 barriers were discovered by an in-depth literature review and the judgement of experts as well. Further, integrated “interpretive structural modeling” (ISM) and “decision-making trial and evaluation laboratory” (DEMATEL) approaches are used to evaluate barriers. The ISM technique is implemented to categorize barriers into distinct hierarchy levels and “cross-impact matrix multiplication applied to classification” (MICMAC) analysis to divide barriers among four clusters “independent, linkage, dependent and autonomous.” Moreover, the DEMATEL methodology is applied to classify the barriers among cause and effect clusters.

The integrated ISM and DEMATEL approach suggests that the topmost influencing barriers to the acceptance of EEAs are the lack of Government policies and initiatives, lack of attractive loan financing and subsidized energy prices.

This study would help researchers, regulators, producers, policymakers and consumers to comprehend the need for additional developments and understand that the adoption of EEAs is a current need. Overall, the results of this study expedite stakeholders with the key barriers that may assist to enhance the acceptance of EEAs within the domestic sector.

An extensive literature survey showed a dearth of studies for the identification, modeling and analysis of barriers collectively. Therefore, the current work used the ISM and DEMATEL approaches to fill the gap and to provide more comprehensive knowledge on barriers related to the acceptance of EEA.

Energy-efficient retrofitting of existing buildings is an inexpensive way of reducing energy consumption and mitigating climate change impacts. The purpose of this study is to examine electricity savings and carbon dioxide (CO₂) emission reduction potentials of energy-efficient retrofit measures for surveyed two large shopping malls in India.

A techno-economic model was developed to estimate the electricity savings achieved due to energy-efficient retrofit measures in shopping malls that were surveyed in 2017. Alternative scenarios were constructed based on capital cost and cost of conserved energy (CCE) value for retrofit measures: cheapest replacement, best available technology and best value for money. The life-cycle electricity and CO₂ emission savings and payback period for end-use retrofit measures were evaluated.

The estimated average electricity savings were around 39–56% for various retrofit measures across all three scenarios while the average CO₂ emission reductions were around 50–125 kt-CO₂. Retrofits to light-emitting diode lights and air conditioners with inverter technology offered more life-cycle electricity savings. Paybacks for most lighting end-use measures were estimated to be within 1.5 years while for most space conditioning end-use measures were between 1 and 4 years.

The primary survey-based comprehensive research makes an exclusive contribution by estimating life-cycle electricity savings and CO₂ emission reductions for energy-efficient retrofit measures of lighting and space cooling end-use appliances for existing shopping malls. The present research methodology can also be deployed in other types of commercial buildings and in residential buildings to estimate electricity savings from energy-efficient retrofit measures.

This study aims to examine the antecedents of purchase intention toward energy efficient air conditioners by incorporating the theory of planned behavior (TPB) with two additional constructs, i.e. environmental concern and personal norms. TPB is one of the most widely used theoretical framework to study consumer behavior.

The study applied a quantitative technique using a survey method by distributing self-administered questionnaires among the Indian households who have purchased energy efficient air conditioners in the past six months or had enquired to do so. The study collected data from three select regions: Delhi and NCR, Punjab and Tri-city. The collected data of 424 respondents have been analyzed using confirmatory factor analysis and structural equation modeling.

The study posits that normative factors such as subjective norms and personal norms have a relatively higher influence on purchase intention. Despite the significant existence of environmental concern, the study did not find environmental concern directly influencing purchase intention.

The sample size of the study is too small and pertains to specific regions. Thus, it could hinder the generalizability of the results. Advertisement appeals should be related with enhancement of self-esteem in terms of making responsible and valuable contribution to environment protection through the purchase of energy efficient air conditioner.

There are a few studies in the Indian context studying consumer’s purchase intention toward energy efficient air conditioners to which this study adds. The study provides an important contribution to marketers in developing strategies for increasing purchase intention toward energy efficient air conditioners in view of their stage in the product life cycle, diffusion of product and influence of normative factors.

The purpose of this paper is to seek ways to improve energy efficiency in the residential building sector of Nigeria. This is necessary so as to promote a wider scope of energy efficiency practice in order to reduce energy demand on the central power supply of the nation and as well-attain reasonable level of energy security.

However, the objective of the study is to propose a strategic plan (scheme) of energy efficiency practice for the housing sector of the Nigerian economy. To accomplish this task, a review of the main issues of energy efficiency; the current energy situation in Nigeria; and the challenges to implementing energy efficiency in the country was undertaken.

Finally, remedial measures to achieving energy efficiency in the Nigerian households were proffered by the provision of a “strategic scheme” to be accomplished by the government and the housing stakeholders.

It is evident that a strategic plan or framework must be put in place in order to overcome the challenges of energy efficiency in the residential building sector. And this framework is to adequately address the issues of design practice, the efficiency of appliances in use and the housing occupant behaviour.

The main goal is the attainment of energy-efficient households in Nigeria through the application of EE practice strategies.

The study highlights on the energy development level of the country. It has also identified the numerous barriers as well as the principal actors to achieving energy-efficient households in Nigeria. After all, the suggested “plan of action” as provided in the scheme is to serve as a benchmark and reference point to the government, the housing stakeholders as well as the housing occupant for the attainment of energy efficiency.

Some of the major concerns since the implementation of smart meters (prepaid meters) in some parts of Ghana is how electricity consumers have benefited from data obtained from these meters by providing important statistics on electricity-saving advice; this is one of the key demand-side management methods for achieving load reduction in residential homes. Appliance shifting techniques have proved to be an effective demand response strategy in load reduction. The purpose of this paper is therefore to help consumers of electricity understand when and how they can shift some appliances from peak to off-peak and vice versa.

The research uses an analysis technique of Richardson et al. (2010). In their survey on time-of-use surveys to determine the usage of electricity in households as far as appliance shifting was concerned, this study allowed for the assessment of how the occupants’ daily activities in households affect residential electricity consumption. Fell et al. (2014) modeled an aggregate of electricity demand using different appliances (n) in the household. The data for the peak time used in this study were identified from 05:00 to 08:00 and 17:00 to 21:00 for testing the load shifting algorithms, and the off-peak times were pecked from 10:00 to 16:00 and 23:00. This study technique used load management considering real-time scheduling for peak levels in the selected homes. The household devices are modeled in terms of controlled parameters. Using this study’s time-triggered loads on refrigerators and air conditioning systems, the findings suggested that peak loads can be reduced to 45% as a means of maintaining the simultaneous quality of service. To minimize peak loads to around 35% or more, Chaiwongsa and Wongwises (2020) have indicated that room air conditioning and refrigerator loads are simpler to move compared to other household appliances such as cooking appliances. Yet in conclusion, this study made a strong case that a decrease in household peak demand for electricity is primarily contingent on improvements in human behavior.

This study has shown that appliance load shifting is a very good way of reducing electrical consumption in residential homes. The comparative performance shows a moderate reduction of 1% in load as was found in the work done by Laicaine (2014). The results, however, indicate that load shifting to a large extent can be achieved by consumer behavioral change. The main response to this study is to advise policymakers in Ghana to develop the appropriate demand response and consumer education towards the general reduction in electrical load in domestic households. The difficulty, however, is how to get the attention of consumer’s on how to start using appliances with less load at peak and also shift some appliances from off-peak times. By increasing consumer knowledge and participation in demand response, it is possible to achieve more efficiency and flexibility in load reduction. The findings were benchmarked with existing comparison studies but may benefit from the potential production of structured references. However, the findings show that load shifting can only be done by modifying consumer actions.

It should be remembered that this study showed that the use of appliances shifting in residential homes results in load reduction benefits for customers, expressed as savings in electricity prices. The next step will be to build on this cost/benefit study to explain and measure how these reductions transform into net consumer gains for all Ghanaian households.

Load shifting will include load controllers in the future, which would automatically handle electricity consumption from various appliances in the home. Based on the device and user needs, the controllers can prioritize loads and appliance usage. The algorithms that underpin automatic load controllers will include knowledge about the behaviors of groups of end users. The results on the time dependency of activities may theoretically inform the algorithms of automatic demand controllers.

This paper addresses an important need for the country in the midst of finding solutions to an unending energy crisis. This paper presents demand response to the Ghanaian electricity consumer as a means to help in the reduction of load in residential homes. This is a novel research as no one has at yet carried out any research in this direction in Ghana. This paper has some new information to offer in the field of demand in household electricity consumption.

The purpose of this study is to develop a theoretical framework of consumers’ purchase intention of energy efficient home appliances.

Non-probability quota based on age and education and purposive sampling technique have been used to assess data collected by a questionnaire survey.

The findings of the study reveal that consumers’ knowledge of eco-labels, environmental concern and perceived consumer effectiveness are the important predictors of purchase intention. However, the positive relationship between green trust and products’ functional value was found insignificant. It is believed that consumers’ are skeptical about products’ functional benefits.

Although this study has presented a holistic approach to assess consumer purchase intention for energy-efficient home appliances, there are some limitations of the current study. First, this study has focused on consumer intention to purchase energy-efficient home appliances rather than actual purchase of appliances. Ajzen (1991) argued that intention is the accurate and immediate measure of actual, but gaps exist between intention and the actual behavior of the consumers (Ajzen and Fishbein, 1980). Consumers’ intentions may not always result in actual behavior. Thus, to expand research applicability, researchers should include actual behavior of consumers by conducting interviews or collecting data from the same consumers after an interval of three to six months. Second, the study has focused on consumers’ psychographic variables, there may be many other factors such as technological variables, government and pressure group influence and media impact on consumer intention to purchase energy-efficient home appliances. Future studies can integrate the impact of these potential variables on consumer purchase intention of energy-efficient home appliances with the same model. The third limitation is related to the methodology of this study, the quantitative method has been used in this study. Future studies may use qualitative and mixed methods to better understand consumers’ inclination of purchase intention of energy-efficient home appliances in Pakistan. Besides, a qualitative study will be helpful to explore new variables that are essential in the decision-making of consumers for the purchase of energy-efficient home appliances in Pakistan. Pakistan is a developing country where the majority of the people are belonging to the middle-class; there may be many other important factors that affect consumers’ purchase intention of energy-efficient home appliances. Therefore, an in-depth qualitative study would be helpful to explore those variables in the context of a developing country.

Energy consumption has posed serious threats to the sustainability of the environment and endangered the lives of many species across the globe. Environmental degradation due to unsustainable consumptions has provided ample opportunities to the marketers that led to the development of sustainable products such as energy-efficient home appliances. In this study, the antecedent of purchase intention of energy-efficient appliances includes attitude, functional values, perceived consumer effectiveness, consumers’ knowledge of eco-labels, environmental concern and green trust. Although researchers have extended TBP to predict consumers’ purchase intention of energy-efficient appliances, studies lack to provide a holistic view from consumers’ perspective. Consumers’ concern for the safety of the environment depicts consumers tendency to purchase environmentally friendly products and promote less hazardous products. Marketers should incorporate environmentally friendly benefits to the product that serve to attract maximum consumers and maintain harmony with the environment. Consumers’ knowledge of eco-labels, green trust and functional values are a vital construct that needs focus in term of the energy-efficient appliances purchase decision. Eco-labels are one of the emerging marketing tools that serve to guide consumers related to products environmentally friendly attributes and contribute to the acceptability of products. Marketers can use eco-labels to differentiate green products from conventional and establishes consumers’ trust in product performance.

This study is relevant to energy-efficient home appliances. Systematic literature of previous studies suggested the need to conduct and examine the antecedents of energy-efficient home appliances in developing markets. This research highlights that perceived consumer effectiveness is the most influencing factor affecting intention. The implications of this study would be helpful in understanding consumers’ behavior toward the purchase of green products in developing markets.

Improving energy efficiency of buildings and appliances has been shown to be the most cost‐effective way of reducing greenhouse gas emissions. The aim of this research is to identify householders' lifestyle choices within homes that impact on energy use and their motivation to conserve energy. The results help to identify methods to increase the uptake of sustainability practices that will reduce greenhouse gas emissions in residential buildings.

A postal survey was adopted as the quickest and most cost‐effective way of surveying a large sample of householders across Australia. The survey was sent to 2,500 randomly selected residents, 500 in each of the five largest Australian cities by population.

The results identified that barriers to energy efficiency in households include: larger homes and smaller households; initial costs of sustainable features, and a lack of consumer information about benefits and savings from incorporating energy‐efficient devices. The most common reason why people are not acting in more sustainable ways is inconvenience or laziness.

The response rate was very low and retired persons were over‐represented, as they are the people with more time to answer surveys. Further research is warranted to achieve a larger, more representative sample.

These results will be useful to Government policy makers as they help to identify methods to increase the uptake of sustainable features and energy conservation in homes.

This study is the first attempt at a nation‐wide study of residential behavior to help reduce greenhouse gas emissions in homes.

The purpose of this paper is to investigate the influence of consumers’ collectivism and long-term orientation (LTO) cultural values on their purchase intention in relation to environment-friendly products.

This research adopts a hypo-deductive research design. A unique conceptual model was developed by linking cultural values to key determinants of green purchase behaviour. This model was then tested using a quantitative survey of 682 shoppers in popular Vietnamese electrical appliance stores.

Analysis using structural equation modelling reveals that consumers with greater adherence to collectivism and LTO tend to engage in green purchase behaviour owing to their positive environmental attitudes, strong subjective norms and tolerance of inconvenience associated with eco-friendly product purchase. Gender is found to moderate the relationship between the determinants and purchase intention.

Marketers including manufacturers and policymakers must endeavour (change globally) to reduce or eliminate perceived inconvenience associated with green purchases. They should also effectively communicate messages stressing that eco-friendly product purchases are crucial for environmental protection and benefit consumer groups including family, peers and society in the long-run.

This research is the first of its kind which links consumers’ cultural values at a personal level to all the elements of the theory of planned behaviour. This research also extends current knowledge about green purchase behaviour in emerging markets by focussing on Vietnam.
