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.     

The Demand for Residential Space and Water Heating Fuel by Energy Conserving Households

A model of residential demand for the natural gas used in space and water heating is developed. Parameter estimates of thermal efficiency, internal design temperature, furnace efficiency, family, and economic variables are derived for a sample of households defined as “energy conservers” by virtue of having retrofitted their homes. The paper also addresses econometric problems of simultaneity and index bias. Results indicate that, for this sample, residential demand for natural gas is price elastic.

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.

中国城市能源效率测算

伴随着中国的快速城市化进程,能源消耗总量不断攀升,其中城市能源消耗量占到绝大比重,故科学测算与认清城市能源效率状况,对于制定合理的能源政策具有重要意义。借助多渠道的统计数据和细致的数据预处理,文章在以永续盘存法估算城市资本存量的基础上,借鉴Zhou等(2012)基于Shephard能源距离函数的能源效率定义,将劳动和资本的无效率从生产函数中分离出来,采用随机前沿分析(SFA)测算我国2001-2013年245个地级以上城市的全要素能源效率,并开展四大地区、南方北方、不同规模等级城市全要素能源效率的差异分析。结果显示,地级以上城市能源效率平均水平略高于0.6,能源效率排名前10位城市主要位于东部沿海地区,后10位城市则主要位于西部地区;四大地区、南方北方及不同规模等级城市的能源效率及变动趋势表现出明显差异,总体上都存在较大的节能潜力空间。

基于天线选择技术的大规模下行MU-MIMO系统能效分析

为了提高大规模多用户多输入多输出(MU-MIMO)下行系统的能效,提出了一种基于发送天线选择技术的能效优化机制。首先建立了同时考虑发送功率与电路功耗的新的系统功耗模型,并基于该模型,分析了基站配置天线数目与所有接收终端用户数目对系统总功耗及能效的影响。然后通过理论推导得到了系统能效最优时的最优天线选择数目,并与使用全部天线时的系统能效进行比较。仿真结果表明,所提出的发送天线选择机制通过优化激活部分基站天线能够明显提高系统能效。在用户数为10、发送功率分别为40 W和10 W时,与使用全部天线相比,天线选择技术能够分别使得系统能效获得大约12%和78%的性能增益。
