| Summary/Abstract |
This paper discusses domestic energy use and energy behaviour. It shows some improvement in domestic energy consumption and adoption of good energy practice. The survey conducted indicated that 35% of homes could improve their energy efficiency by improved tank insulation. In the last 5 years condensing boilers have been installed only in 3% of homes, indicating that householders are unaware of their advantages. Although 88% of surveyed homes had purchased a major appliance in the last 2 years, only 16% had any idea of the energy rating of their new appliances. Use of energy saving light bulbs is predominant in kitchens compared to other rooms. 70-80% of householders undertook some kind of day-to-day energy efficiency measures. 20-35% of householders would like to invest in energy-saving measures but found cost to be a key barrier. Approximately 84% of those surveyed were unaware of the energy rating of their household appliances. Price and brand were the most important factors determining the purchase of a new appliance. Significant energy-saving could be achieved by providing appropriate information to the general public regarding temperature control, efficiency of appliances and energy-saving heating systems.

| Summary/Abstract |
Governments worldwide have placed much effort into improving energy efficiency to realize energy conservation and carbon emission reduction. However, households' investment in energy-efficient products seems not as positive as expected, resulting in the energy efficiency gap. The phenomenon concerning Chinese households and its underlying causes have been overlooked to a considerable extent within the extant literature. The present study endeavours to elucidate the role of present bias in shaping people's energy efficiency investment behaviour. To this end, an online survey containing a sample of more than 3000 individuals residing in Shanghai and Beijing, China was conducted. It is found that: (1) Evidence shows that about one-third of the respondent are present-biased consumers according to the results of survey-elicited time preferences. (2) All else being equal, those showing present bias are significantly underinvesting in energy-efficient appliances. This is reflected in lower adoption rates of energy-efficient electric heaters, water heaters, and washing machines. (3) Present-biased energy consumers exhibit an attention deficit regarding the energy costs of home appliances and may also encounter higher energy bills. (4) Those with signs of being sophisticated, namely, self-aware of the bias, may improve energy-related decisions, thereby mitigating the behavioral failures. This paper underscores the need to aid individuals in recognizing and addressing the present bias when promoting energy-efficiency products.

| Summary/Abstract |
Energy Star (ES) appliances are required to provide the same features and performance as their unlabeled counterparts, but do so with increased efficiency. However, the expected energy savings from such labeling may not be as great as expected. This paper contributes to previous research on ES labeling by examining household behavior and electricity consumption. Using two different household surveys on energy use, we provide a first attempt to estimate the impact of ES appliance ownership on actual household electricity usage. The results show a significant effect for ES refrigerators reducing electricity use, while the analysis for ES televisions suggests an increase in electricity usage by LCD TV owners. The findings highlight the need for more research on household energy consumption and the efficacy of the ES appliance program.

| Summary/Abstract |
The speed at which many energy efficient technologies have been adopted has been very slow and the reasons why this is the case are often not well understood. An important area for New Zealand is domestic hot water which typically accounts for one-third of a household's electricity usage. We use in-depth interviews to examine the decision processes of six householders who were replacing existing hot water systems or building new homes. We also interviewed different trades people and professionals advising those households. Seven themes emerge from the interviews which demonstrate huge inertia to change. Using methods from decision sciences we also construct an information processing model describing the possible steps in the adoption decision. This model emphasises the complexity and difficulty a householder currently faces if they wish to pursue an alternative system for heating hot water.

| Summary/Abstract |
While physical interventions such as external wall cladding can improve the energy efficiency of domestic properties, how residents think about and respond to such interventions can influence both their uptake and impact on the household's energy use. The present research investigated what residents living within deprived communities in Yorkshire and the Humber (United Kingdom) thought about a number of household energy efficiency interventions proposed as part of a project known as "The BIG Energy Upgrade". The Theory of Planned Behaviour was used as a framework for investigating residents' beliefs. Residents generally felt positive about the proposed interventions and expected that they would lead to financial savings, improve the appearance and warmth of their homes, and sense of pride in the local community. However, while residents intended to adopt energy efficiency interventions if offered them, they were less willing to personally invest in them. Home ownership and the belief in humans' ability to tackle climate change were found to predict willingness to invest. These findings help to understand responses to initiatives that seek to improve the energy efficiency of hard-to-treat homes.
