| Summary/Abstract |
This article investigates the barriers to energy efficiency at the residential sector within one province in China and explores patterns of household electricity consumption. The article presents the results of a survey questionnaire distributed to more than 600 households in Liaoning Province, field research at various Liaoning government agencies, and research interviews of Liaoning government officials to determine the efficacy of their energy efficiency efforts in China. It then investigates the extent that electricity consumers have taken advantage of energy efficiency opportunities relating to more efficient lights, water heaters, appliances, air-conditioners and heaters, and better energy-efficiency labels. The article also assesses the degree that electricity users have become more aware about electricity prices and their levels of consumption, and touches on the connection between rising levels of income and electricity use. It concludes by providing recommendations for how to improve efforts to promote conservation and reduce electricity load growth in Liaoning Province and beyond.

| Summary/Abstract |
Building energy efficiency standards (BEES) are believed to be one of the most effective policies to reduce building energy consumption, especially in the case of the rapid urbanization content in China. However, there is little evidence backed up by measured data to validate the actual effectiveness of BEES in China. Using survey data collected from 1128 households in Chongqing China, this study applied the propensity scores matching method to estimate the effect of two BEES levels: the 50%-BEES (low level) and the 65%-BEES (high level). Results show that buildings built with 65%-BEES, on average, can reduce cooling and heating electricity use intensity (kWh/m2/a) by 41%, compared to buildings in the absence of the BEES. Meanwhile, the adoption of 50%-BEES can reduce cooling and heating electricity use intensity (kWh/m2/a) by 38%. However, energy savings are not significant if comparing buildings with 65%-BEES and 50%-BEES. The results indicate that there exists a performance gap between calculated design performance savings and actual operation energy savings. These empirical findings provide policymakers with valuable feedback on buildings' actual performance. The findings suggest that it is necessary to incorporate outcome-based compliance pathways into the current BEES system. Lastly, a data-driven building policy evaluation mechanism should be developed in China. Energy consumption databases should be developed to support policies such as building energy codes and standards' development and performance evaluation.

| Summary/Abstract |
This paper analyzes the effects of providing feedback on electricity consumption in a field trial involving more than 1500 households in Linz, Austria. About half of these households received feedback together with information about electricity-saving measures (pilot group), while the remaining households served as a control group. Participation in the pilot group was random, but households were able to choose between two types of feedback: access to a web portal or written feedback by post. Results from cross section OLS regression suggest that feedback provided to the pilot group corresponds with electricity savings of around 4.5% for the average household. Our results from quantile regressions imply that for households in the 30th to the 70th percentile of electricity consumption, feedback on electricity consumption is statistically significant and effects are highest in absolute terms and as a share of electricity consumption. For percentiles below or above this range, feedback appears to have no effect. Finally, controlling for a potential endogeneity bias induced by non random participation in the feedback type groups, we find no difference in the effects of feedback provided via the web portal and by post.

| Summary/Abstract |
Bangladesh, a climate-vulnerable country, has taken initiatives to reduce greenhouse gas emissions. The country's most significant challenge to achieving that goal is keeping economic growth even after ensuring commercial and residential energy for its people, primarily dependent on fossil fuel. This research investigates the residential electricity and gas consumption and its effect on Bangladesh's economic growth with the data period 1975–2018. Household energy consumption is one of the critical factors for sustainable economic growth, although it is not directly converted to the country's manufacturing output. Autoregressive Distributed Lag (ARDL) bound testing approach has been used due to the robust and better performance in this study with the smaller size of the sample. The country's labor-intensive economy has been found with a unidirectional relationship from household electricity consumption and population growth, which stresses the significance of ensuring electricity for all. Therefore, the country cannot take the energy conservation policy right now as it could obstruct its growth. However, energy sources might be replaced with renewable energies to meet the country's residential energy demand.

| 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.
