“…The experience of Japan from the 1950s to the 1990s (H. Nakagami, 1996) foreshadows the steadily increasing importance of electricity in modern domestic life in the pursuit of a more comfortable life in China, and that the link between lifestyle and electricity will grow stronger. L. Lopes et al (2005) considered that energy consumption is closely related to the resident's lifestyle. With rising real income, consumption becomes an act of pleasure beyond satisfying basic needs.…”

Consumer behavior is one of the most important issues with respect to household energy consumption. This paper will evaluate the energy-saving potential of improving consumer behavior on the basis of a field study. In the original survey plan, the monthly electricity use of households in three typical residential buildings in the city of Hangzhou, China, were monitored from April 2007 to July 2008. A total of 124 households in those buildings were selected as the subject households. Half of them were informed of 34 energy-saving measures before July 2008 to teach them how to improve their behavior and control electric appliances in their daily lives. Finally, a questionnaire survey was administered in the beginning of August 2008 to identify the changes in the occupants' behavior. Based on the comparison analyses among the differences in the electricity uses of the 71 remaining valid samples, the conclusions can be drawn that: (1) residential electricity use will increase continually in the near future in China due to improved standards of living and a greater dependency on electric appliances, and (2) more than 10% of household electricity use can be conserved by informing occupants of energy-saving measures to improve their behavior.

“…To explore the energy saving potential relating to electric appliance purchase, Anibal et al 16) analyzed the annual electricity saving from replacing existing inefficient technologies with the Best Available Technology (BAT), in a typical household. Moreover, Lopes et al 17) have provided detailed information about the use patterns of major domestic appliances such as TVs, rice cookers and refrigerators, for both their operation mode and length of use. Finally, they evaluated the impact of these use patterns on residential electricity use.…”

“…In the past several decades, a number of studies on occupant behavior in residential buildings have been carried out in European countries, Australia, the USA and Japan [13][14][15][16][17][19][20][21][22][23][24] , before the importance of occupant behavior was officially realized in China. For example, in addition to emphasizing the variation of household electricity use among dwelling units, the variations of major end-use loads have also been described and analyzed based on field measured data.…”

In order to gain a good understanding of residential building energy consumption in China, a case study about occupants' use of electricity for lighting, appliances and room air conditioners was carried out in 44 identical apartments in Beijing. Additionally, two apartments with significantly different energy consumption levels were chosen for a detailed study about the impact of occupants' daily behavior in using lighting, appliances and room air conditioners. The results of this study demonstrate the important contribution of occupant behavior to the significant variation of electricity consumption among residential buildings. The detailed measurement of occupant behavior showed a potential in better understanding how energy is consumed in buildings and relevant information gathered from this process can help occupants change their behavior for energy saving.

“…He argued that there exists a significant positive relationship between energy prices and energy saving, and that energy saving measures will affect each other in such a ways as to reduce the energy saving potential; however, it does not affect the price sensitivity of energy saving measures. Lopes et al (2005) [18] conducted a detailed questionnaire survey on household energy consumption among 13 households in Kansai, Japan, and found that energy price was the main factor influencing energy consumption. In light of this, it can further be argued that successful energy policies need to consider the use of pricing tools to make the costs for residents more reasonable.…”

Abstract:In recent years, a coal-induced haze erupted over a large area in China. Implementing a strategy of substituting electricity for scattered coal (hereafter referred to as SEFSC) for the control of scattered coal is thus urgently needed. In particular, there lies great practical significance in analyzing the existing problems and improving the path of SEFSC in order to ensure rapid and effective advancement in this area. In light of this, the current paper first analyzes the distribution of China's scattered coal and the relevant policy implementation, and discusses the potential for China to implement SEFSC. Secondly, PEST (policy, economy, society and technology) analysis is used to analyze the existing problems in China's SEFSC strategy. From this, it becomes clear that the effect of scattered coal handling is still poor due to poor policy implementation, a weak economy, a low level of social acceptance and technical bottlenecks. Finally, based on the present situation and existing problems, this paper puts forward recommendations for improving China's SEFSC strategy.
