Residential energy behaviour: does generation matter?

In this study we tested the relevance of the generational hypothesis, that is, whether the era in which household members grew up matters when understanding and predicting their behaviour, on a sample of 600 Swedish households. These households participated in a survey where they answered questions about their own energy‐related residential energy behaviour. The answers were analysed for differences between age groups, between different attitudes to environmental issues, between income levels and between dwelling types. The results showed that age was as good an indicator as the other parameters. In several areas, older households had a more energy‐efficient residential behaviour than younger ones. Examples are laundry practices and indoor heat regulation. According to the generational hypothesis, this finding implies higher energy use in the future. The study also shows that there is a broad scope for improving residential energy behaviour in Swedish society by implementing changes in laundry avoiding practices, dishwashing behaviour and indoor temperature regulation.     

Consumer voices: adoption of residential energy‐efficient practices

The purpose of this research is to identify constraining variables that may impinge on adopting energy‐efficient practices, materials, equipment and technology in households. The intent is to uncover relationships of attitudes, beliefs, knowledge and other resource constraints to: (1) existing housing adaptations and adjustments for energy efficiency; and (2) more efficient use of energy in homes. A second objective is to identify existing practices used to reduce energy use and the adaptations made to the existing structure, materials, equipment and technology for energy efficiency as well as their intentions to make future adaptations. Constraint variables include knowledge of existing energy‐efficient practices and technology; economic constraints (household income, cost as a problem, financial need and existing energy costs); obstacles to making changes (lack of information, assistance, time, cooperation, trained persons and the condition of home); and demographic variables (age, education level and urban/rural). Attitude and belief constraints include measures of felt responsibility for energy use‐related actions that impact the natural resources and environment, and measures of concern. These constraints may impinge on or contribute to making energy‐efficient changes in residential households. Questionnaires were mailed to a random stratified sample of 800 households in Nebraska (US state) in April and May of 2008, resulting in a 29% return rate. The analysis indicates that the research produced information about constraining factors that impact the existing energy‐efficiency levels of households. The use of energy‐efficient equipment and technology, and behaviour practices that reduce energy use are related to those barriers. However, residential energy use and behaviour change result from a range of psychological and contextual influences on behaviour. Behaviour is often inconsistent with attitudes because of the presence of various constraining factors that preclude consistency with behaviour. Educational programmes have a challenging task if they are to alter attitudes and norms to overcome situational constraints. It may be more fruitful to educate and to remove the constraints impinging on those who already have a positive attitude about the need to increase energy efficiency for whatever reason.     

Promoting green buildings: Do Chinese consumers care about green building enhancements?

This paper explores sustainability‐related choices about buildings by analysing how consumers rated the relative importance of various attributes of conventional and green buildings. It also analyses how consumers judge environmental and health‐oriented improvements in green buildings. Unlike previous studies, this research applied conjoint analysis to explore the green building market at the consumer's level by regarding green buildings as nondurable green products and services. We used a survey to gather consumer preferences about several green building hotel models which partly applied green energy, modern wood structures and improved indoor environmental quality (IEQ). In total, 341 consumers participated the survey in two of China's largest cities: Beijing and Shanghai. The results revealed that green energy was the most preferred attribute of green buildings, exerting an even stronger overall effect on consumer choice than price. Afterwards, we identified distinct consumer segments and determined the background characteristics of each segment based on the similarities in the preferences for each attribute. The largest consumer segment, consisting of younger consumers, ranked green energy as the most important criterion. However, an improved indoor environmental quality was generally not highly ranked, and individuals in the consumer segment, which included more older and female consumers, were more likely to reject modern wood structures. The results also revealed that higher‐income individuals were most concerned with price, and consumers with higher levels of education were willing to pay more to support green buildings.     

The effects of demographic characteristics on consumer information periodical readership and financial knowledge

A telephone survey of French- and English-speaking households in Quebec was conducted to obtain information about money management practices, of use information sources and knowledge of personal finance terminology. Correlations and regressions were performed on data from 234 interviews. An index of consumer periodical readership was related positively to variables for female respondent, English-speaking, urban residence, income and education in the correlations. A financial knowledge index was related positively to variables for income, education, and the periodical index in the correlations. The knowledge index peaked for the 41–55 years of age category. A two-equation recursive model for periodical readership and financial knowledge was tested. A regression on the periodical index had positive effects for income, education and variables for age 56–64 and 65 and over, and a negative effect for rural location. A regression on the knowledge index had positive effects for the periodical index, income, French-speaking and the variable for age 41–55, and a negative effect for female respondent. The needs of lower income consumers may not be met well by consumer periodicals. In terms of financial knowledge, English-speaking consumers in Quebec may be at a disadvantage relative to French-speaking consumers with similar income levels.     

Older adults: clothing preferences for thermal comfort in cold weather

Escalating energy prices and widely publicized energy saving practices in the last decade have induced some older consumers to lower household temperatures during cold weather. Therefore, the effective manipulation of clothing warrants consideration in maintaining thermal body comfort. The purpose of this research was to determine the clothing preferences of elderly consumers indoors during cold weather. Four hundred and fifty questionnaires were administered at three locations. Results from the study revealed that comfort was the most significant factor in selecting warm clothing. Although the respondents had implemented the effective use of clothing to achieve thermal comfort, the use of supplemental heat, and control of thermostat setting for heat was more prevalent. Suggestions and recommendations are made for practitioners who would address the issues of clothing for thermal comfort and energy conservation.     

Retailers and Consumers: The Pass‐through of Import Price Changes

In this paper, we estimate pass‐through rates of import price changes to retail prices across retailers and consumers for apparel purchases in Germany for the period of 2000–07. We find that high‐price retailers do not pass through changes in the import price. Pass‐through rates for low‐price retailers are 53 per cent within three months. Consequently, pass‐through rates for low‐income households are 58 per cent, significantly larger than those for high‐income households. We then present one possible explanation for these observations in a theoretical model with endogenous vertical product differentiation due to bundling an ex ante homogeneous import goods with services. Following an import price change, retailers who sell a cheaper unbundled product change prices to a greater extent than retailers who sell a higher‐priced bundle of product and service.     

The adoption of sustainable laundry technologies by US consumers

The adoption of sustainable laundry technologies by US consumers has lagged behind that of other countries and even behind the projections for adoption made by the US government. Most US household currently own and use the top‐loading vertical axis (v‐axis) agitator type washers, which use large amounts of water as well as additional energy to heat the water. More sustainable laundry practices include the use of energy‐ and water‐efficient front‐loading horizontal‐axis (h‐axis) washers. These washers have been demonstrated to use 38% less water and 58% less energy than the standard top‐loading v‐axis models. The adoption of more energy‐efficient washing technologies is of interest to many, including policy makers, because of their water‐ and energy‐saving potential. Little is known about the attributes and issues consumers use in their decision to adopt high‐efficiency washers for their home. This study uses Roger's Diffusion of Innovations Theory to understand the adoption of h‐axis washers by US consumers. An online survey of 330 consumers who own washing machines found that 23% currently own h‐axis washers and 24% of consumers intend to purchase an h‐axis when they replace their top‐loading vertical (v‐axis) washers. Energy and water savings are the most frequently cited reasons overall for adopting the h‐axis washer and cost was the main reason for not adopting the technology. Other issues, such as dissatisfaction with cleaning power and problems with machine cleanliness and maintenance, did not play a major role in adoption. Specific marketing and education channels, where US consumers are looking for information about h‐axis washers, are also identified. Overall, the results suggest that the rate of h‐axis adoption in the US is accelerating, but that many of the benefits of the technology are not easily observed by non‐owners.     

Domestic fuel expenditure and payment of fuel allowances

The allocation of additional requirements for heating to households on supplementary benefit (SB) has been challenged recently. Some households receiving an addition spend less on fuel than others which do not. The fuel expenditure of any household on SB is likely to be constrained by income and may reflect ability to pay rather than need. A group of households with zero or close to zero income elasticity for fuel expenditure is identified. The expenditure on fuel of these households can be considered not to be constrained by income and to reflect the real costs of maintaining a warm home in given circumstances. Their expenditure is then used to indicate how fuel allowances might be better targeted.     

Automatic dishwashers: efficient machines or less efficient consumer habits?

Increasing costs for energy and water influence consumer decision making when purchasing white goods, such as dishwashers. Since the implementation of the European Energy Label, considerable improvements in water and energy consumption of dishwashers has been achieved, and for consumers, efficiency has become one of the main buzzwords when buying any major new household appliance. However, ownership of an efficient dishwasher in itself does not guarantee savings in energy and water during the course of the dishwashing process. Conservation of resources also requires changes in consumer behaviour. This paper provides empirical data on consumers' dishwashing habits in everyday life in four European countries, deals with the influence of their behaviour on the efficiency of the dishwashing process and highlights savings potentials in the usage of dishwashers. It reports on the results of a survey involving a total of 1209 online interviews conducted in winter 2006/2007. The survey data have been analysed to reveal the importance of various product attributes for consumers and show that low water and energy consumption values are the most important consideration for the respondents in terms of their purchasing decision. But this is compromised, at least in part, by less efficient dishwasher use, e.g. in pre‐rinsing dishes before placing them into the dishwasher and in the programme choice. In addition, differences in manual dishwashing practices between households with and without a dishwasher, as well as between countries, will be shown. Finally, conclusions are drawn for greater sustainability in the dishwashing process.     

Distributional Effects of Public Investment when Wealth and Classes are Back

In developed economies, wealth inequality is high, while public capital is underprovided. Here, we study the impact of heterogeneity in saving behavior and income sources on the distributional effects of public investment. A capital tax is levied to finance productive public capital in an economy with two types of households: high income households who save dynastically and middle income households who save for retirement. We find that inequality is reduced the higher the capital tax rate is and that low tax rates are Pareto‐improving. There is no clear‐cut trade‐off between efficiency and equality: middle income households’ consumption is maximal at a capital tax rate that is higher than the rate which maximizes high income households’ consumption.     

Distributional effects of multilateral and preferential trade liberalisation: The case of Paraguay

The aim of this work is to dissect the distributional impact of preferential and multilateral trade liberalisation on household well-being using individual level data for Paraguay never exploited so far. For this purpose, the intrazone and applied most favored nation (MFN) tariff pass-through rate on the prices of traded goods is estimated, and the impacts of trade induced price changes on households as consumers and as income earners are calculated. The results indicate that trade liberalisation has benefited households along the entire income distribution and, most importantly, show that these benefits differ according to the type of liberalisation policies implemented.     

Consumers' and retailers' practices and attitudes towards energy-efficient clothing

The purpose of this study was to compare the extent to which consumers and retailers consider energy efficiency in evaluating and selecting indoor sportswear. Little research has been conducted in which retail buyers are subjects; no published research has focused on a comparison of consumers and merchants in regard to their attitudes towards a specific product. The value of such research lies in determining whether a particular consumer need is being met. The results of the present study revealed that retail buyers were less concerned about energy-efficient clothing than were consumers. Significant differences were found between the two groups for four of the nine variables studied. In all cases, consumers gave greater consideration to the energy efficiency of indoor sportswear than retail buyers believed. Further investigation of differences in consumers' and retailers' attitudes and practices is needed.     

Exploring private consumers’ willingness to adopt Smart Grid technology

The goal of radically increasing the proportion of electricity generated from renewable sources puts the current electrical grid under pressure and one of the solutions is to turn the grid into a ‘Smart Grid’. One of the key elements of the Smart Grid is that electricity consumers make some of their consumption available as flexible capacity to balance the grid. Consumers’ flexible capacity is only available to the grid if the consumers adopt Smart Grid technology (SGT) that establishes the link between the electric system and the consumer. This technology is new to private consumers and using it involves behavioural changes. There is a need to get more insight into who are willing to adopt SGT and why. This study draws on innovation adoption theory as a framework for understanding consumer adoption of this new technology. We explore whether consumers who have already adopted other types of new energy technology, such as a geothermal heat pump, are more favourably disposed towards SGT than other consumers. Also, we explore how consumers who have signed up to let their heat pump be used as flexible capacity in a test trial differ from other heat pump owners, if at all. We used semi‐structured interviews with household members as well as a questionnaire to explore differences between three groups: households with (1) a heat pump with SGT (n = 11), (2) a heat pump‐only (n = 7), or (3) an oil‐fired boiler (n = 6). We find that the families in the three groups perceive the technology characteristics differently and those who have trial experience with SGT are most in favour of the technology.     

How practices inform the materialization of cultural ideals in mundane consumption

This study examines how consumers enact cultural ideals in mundane consumption. The empirical context is a weekday dinner practice among Finnish households. The findings demonstrate how practices inform consumers how, where, when, and with whom to enact and compromise cultural ideals and identity projects. Thus the practices guide food consumption choices and the meanings that the consumers ascribe to food consumption objects. The consumers are pragmatic, flexible and fragmented as they enact identity projects and cultural ideals in mundane consumption in relation to practices. They compromise the identity projects and the cultural ideals in some practice(s) but not across practices. As the practices serve different ends for the consumers at different times, the meaning of the practices is constantly re-created by the consumers. The perceived value of mundane consumption is related to how well and how frequently the consumers can enact their identity projects and cultural ideals in practices.     

Credit card usage and consumer debt burden of households

The primary objectives of this study were to examine changes in credit card usage and the amount of debt between 1982 and 1986 and to identify factors influencing the amount of and changes in consumer debt held by households. Personal interviews were completed in 1982 and again in 1986 with the money managers of households in a small midwestern town in the U.S.A. The sample consisted of the 123 households that were represented both in the 1982 and 1986 surveys. Paired-samples t-tests were used to identify changes over time. Significant differences were found between 1982 and 1986 total household assets and total amount of debt. Regression analysis indicated that significant predictors of the amount of consumer debt burden were age, net income, total assets, and the degree to which managers felt comfortable with debt. Younger money managers were more likely to make larger monthly debt payments and have more consumer debt. Households with larger incomes and higher levels of assets also had higher total debt. Significant predictors of change in debt burden over the 4-year period were change in net income and total assets, with year-end savings being negatively correlated with consumer debt.     

Changing laundry habits in Norway

Maintenance is often the most energy‐demanding stage during clothes' life cycle. Therefore, a shift towards more sustainable washing habits has great potential to reduce the consumption of energy, water and detergent. This paper discusses the change in laundering practices during the past 10 years in Norway and suggests strategies to help consumers change their laundry habits to more sustainable ones. Quantitative information of consumers' experiences, habits and opinions concerning clothing maintenance was collected through three surveys in Norway in 2002, 2010 and 2011. The 2010 study was supplemented with qualitative in‐depth interviews of a strategic sample of households. The average washing temperature has decreased slightly during the studied time periods. Some products' washing frequencies remained the same, whereas other products such as jeans were used a few more days before washing. The cotton programme is the most used washing programme, but short programmes are gaining popularity. The laundry sorting processes vary greatly and are influenced by several factors such as washing temperature, colours, fibre type and use area. For some consumers, the use of several different sorting categories made it more difficult to collect a sufficient amount of clothing to fill the machine. They were also afraid that overfilling the machine would result in clothes that were not clean enough or had detergent residues. Detergent dosing practices are far from optimal. In 2010, although the majority of respondents only used eye measure and did not know the water hardness of their area, they still tried to vary detergent dosage based on the amount of laundry and the level of soiling. Different design for sustainable behaviour strategies could be used within detergent dosage systems, care labelling, machine programme selection (such as suggesting lower temperature and eco‐programme), machine filling grade indicators, storage systems for slightly used clothing and textile material choice.     

INFLUENCE OF DEMOGRAPHIC FACTORS ON CONSUMER PURCHASING PATTERNS AND PREFERENCES FOR GROUND BEEF

A study of 198 household units in the Fort Collins, CO area was made to ascertain the importance of such factors as consumer age, income, education and marital status on the purchasing patterns for ground beef. Compared to younger consumers, older consumers tended to: (1) make more frequent purchases of ground beef; (2) buy less ground beef per purchase; and (3) select leaner ground beef. Households with gross incomes in excess of $25,000 tended to buy larger quantities of ground beef per purchase and bought leaner ground beef compared to households with less than $15,000 gross income. In making purchasing decisions, participants in the study considered leanness, visual appearance and price as the most important factors, while packaging and brand name were considered the least important factors.     

Non-market provision of food by low-income households

A model of food provision through growing, hunting or raising food was developed. Food supply was less of a problem for those who grew, raised or hunted their food than for others. Non-market food provision was a viable alternative for consumers regardless of educational levels, income levels and employment status. Home food production varied by other characteristics. There was not a significant difference between urban and rural households in some types of food provided. Results of this study can be helpful to professionals assisting households with resource use and to policy makers concerning policies to assist low-income consumers.     

A situational analysis of consumer science skills used to improve incomes and create self‐employment in the Limpopo province,South Africa

A two‐phase study was conducted in the Mopani and Vhembe Districts of the Limpopo Province of South Africa to identify types of small‐scale businesses used by households to improve their income. The study sample was made up of 240 households from 16 villages and members from 16 organizations working with households in small‐scale, business‐related activities. Phase one of the study collected data on the types of small‐scale businesses carried out by households and organizations assisting them. Phase two developed training manuals and offered training to households. The findings revealed that self‐employment from sales of prepared and processed foods provided the main source of income for most households. Clothing and needlework and housing and art/craft were also used by families to generate income. Problems experienced included lack of technical/management skills, lack of marketing/business skills, inadequate operational funds, low profit margins, unavailability of raw materials and competition from big businesses. The findings highlighted the importance of consumer science‐related skills in poverty alleviation programmes targeting low‐resource households.     

Consumer food safety perceptions and self‐reported practices in Greece

A substantial proportion of foodborne illness is associated with food prepared in households. The primary understanding of how foods are handled in private homes comes mostly from questionnaire based studies and direct observation. The aim of this survey was to examine consumers' perceptions and knowledge of safe food handling practices in Greece. More specifically, their attitudes, opinions and self‐reported practices were studied. Data were collected from a total of 399 consumers living in Greece by the use of a self‐administered on‐line survey. The questionnaire consisted of four positive and five negative statements according to the 5‐point Likert scale, which grouped into three constructions using principal component analysis in order to investigate food safety perceptions of consumers. Furthermore, the survey included 11 demographic questions, two close‐ended questions (type yes/no) and four questions that are related to self‐reported food‐handling practices. The results showed that the most commonly known bacterium causing food‐related illness according to respondents' knowledge is Salmonella (99.7%), followed by Escherichia coli (73.9%) and Listeria (58.4%). The overall consumers' score concerning food safety was 32.8 ± 5.37 (full score was 45). No significant differences to the mean score of food safety knowledge were found according to gender, age or the incidence of foodborne illness over the past 12 months. Knowledge and awareness of safe food handling practices was enhanced at higher education levels, while homemakers were found to have deficiencies at this level. Information obtained from consumers can be used to shape educational programs and determine where food safety educational efforts would be most effective and the needed content of the messages.
