We estimated the price range of electricity transactions under the prosumer system, considering the spread of renewable energy and the prospect of introducing a surplus power trading system between power consumers in Korea. The range (min/max) of power transaction prices was estimated by prosumers and consumers who could purchase electricity from utilities if needed. It is assumed that utilities purchased electricity from prosumers and consumers under a Time-of-Use (TOU) rate, trading at a monthly price. The range of available transaction prices according to the amount of power purchased from utilities and the amount of transaction power was also estimated. The price range that can be traded is expected to vary depending on variables such as the TOU rate, purchased and surplus power, levelized cost of electricity, etc.

The goal of this study was to determine the effect of social responsibility characteristics and consumer attitude on consumer purchasing intention. And we used survey result data from 400 adults (200 males and 200 females) aged between 20 and 50 years for our research sample. Also, this study aims to look at the purchasing intention based on Fishbein's attitude model, in order to predict consumer purchasing behaviors on the products made by corporations that have good social responsibility. By using consumer consciousness of social responsibility and Consumer assessment on corporations' social responsibility, this study also intends to examine the ultimate effects on the intention. The following is a summary of the main results and suggestions. First, less than 30 percent of all consumers have experienced education on social responsibility, which is significantly low. Consumers' education experience had no effects on consumer purchasing intention. Consumers' education experience on social responsibility is surely related to purchasing intention, but gives no meaningful relations from the actual proof analysis, which is because of the problems of current consumer education programs. Government and official institutions, corporations, consumer groups should provide more educational opportunities than broadcast media, internet, school, and printed media. Second, according to the analysis result on Consumer consciousness of social responsibility, the assessment scores on social contribution and environmental protection are relatively lower than on consumer protection and energy resource saving. They tend to focus more on social responsibility related to individual interest rather than broader social responsibility as a member of society. Third, consumers have a positive attitude about corporation and its products made by corporations that have good social responsibility. Fourth, the most contributing factor on consumer purchasing intention is corporate consumer attitude. The next is product consumer attitude, Consumer consciousness of social responsibility, and Consumer assessment on corporations' social responsibility.

This study investigated consumers' energy saving behavior and perceptions concerning the effectiveness of their energy saving behavior. A nation wide survey was conducted involving 2000 households in urban areas and the data from 1767 households were used for the analysis. excluding cases with incomplete responses. Descriptive analysis, factor analysis, and regression analysis were applied. The results were as follows. First, electricity saving behavior was classified into three categories: Thrift (reducing energy consumption), Purchase (buying energy saving appliances), and Control (checking the energy consumption). Second, consumers rated Thrift as the best way to save energy. Third, education, age, and household income were significantly related to energy saving behavior and perceptions on the effectiveness of energy saving behavior. Consumers using above average levels of electricity tended not to practice energy saving behavior and not to positively evaluate effectiveness of the energy saving behavior. Lastly, the implications for public policies to promote energy saving behavior are suggested.

Recently, many actions are taking to accelerate progress toward social consensus and implementation of Smart Grid. Smart Grid refers to a evolution of the electricity supply infrastructure that monitors, protects, and intelligently optimize the operation of the interconnected elements including various type of generators, power grid, building/home automation system and end-use consumers. The most distinguished element will be Advanced Metering Infrastructure (AMI) that will be installed to every end-use consumer's home or building and optimize the energy consumption of the end-use consumer. The key function of AMI is energy management capability that coordinates and optimally controls the various loads according to the operating condition and environments. In this study, we figure out the basic function of AMI in Smart Energy House that can be defined as a model house implementing in Smart Grid. This paper proposes the energy management algorithm that will be implemented in AMI at Smart Energy House. The paper also show how energy saving in Smart Energy House can be achieved applying the proposed algorithm to an actual house model that has mainly lighting, air-conditioning, TV loads.

To lay a solid basis for prosperity and competitiveness, countries should achieve balance in the three fundamental aspects: energy availability, energy affordability and ecological balance. Nuclear energy has attracted international interest as one of the most crucial environmental quality strategies. The objective of this study is to analyze the non-linear link between nuclear energy and environmental quality in the top-10 nuclear energy consumer countries (USA, China, Russia, France, Canada, Spain, Sweden, South Korea, Ukraine, and Germany). Earlier research employed panel data methodologies to examine the linkage between nuclear energy and the environment, despite the fact that many nations did not independently demonstrate such a correlation. On the alternative, this study uses a novel approach known as 'Quantile-on-Quantile,' which allows for the analysis of time-series dependence in each country by giving universal yet country-specific insights into the relationship between the variables. Estimates show that the consumption of nuclear energy improves environmental quality by lowering ecological footprint in the majority of the nations studied at certain quantiles of data. Moreover, the data demonstrate that the degree of asymmetries between our variables changes by nation, emphasizing the importance of policymakers exercising caution when adopting nuclear energy and environmental quality regulations.

본 연구에서는 공사의 중점적 업무인 임대주택 부문을 대상으로 거주자의 에너지 소비실태, 거주 만족도 및 에너지 절약 방안을 분양주택 거주자와 비교를 통하여 그 차이를 분석하고 효율적인 에너지 대응방안을 모색 하는 것을 목적으로 하고 있다. 임대주택 거주자의 에너지 지출 비용은 분양주택 거주자에 비하여 가스, 전력 모두 약 절반 수준으로 조사되었으나, 전력의 경우 실제 소비량의 차이는 약 30% 수준으로 큰 차이를 보이지 않았으며 이는 가전기기의 보유수, 용량 등에 기인하는 것으로 나타났다. 또한 분양, 임대 모두 현재의 에너지 소비지출에 대한 부담 수준에서 "부담되지 않음", "약간 부담"이라는 응답비율이 전체의 80%이상을 차지하고 있으며 이는 삶의 질적 향상 요구와 함께 임대주택 부문에서도 에너지 소비가 증가 할 수 있음을 의미하고 있다. 에너지 절약 방안의 효과성과 필요성에 대한 IPA결과 분양주택 거주자에 비하여 상대적으로 임대주택 거주자가 절약에 대한 관심 및 의식수준이 낮은 것으로 나타났으며, 특히 에너지 정보 제공에 대한 부분을 저평가하는 것으로 분석되는 등 임대주택 거주자에 대한 적극적인 에너지 대응이 필요한 것으로 조사되었다. 이를 위해서는 에너지 소비에 대한 관심도와 중요도에 대한 의식전환의 계기를 제공할 필요가 있으며 임대주택 거주자들을 대상으로 하는 에너지 관련 교육 및 홍보 등의 노력이 필요한 것으로 판단된다.

The industry has rapidly growth and energy supply technology advanced are become main factor which to contribute of the harmonic losses. This problem is one aspect that may affect the capability of the transmission line and also to the efficiency of electricity. This paper proposes a new scheme to allocate the cost pertaining to transmission loss due to harmonics. The proposed method, called as Generalized Harmonic Distribution Factor, uses the principle of proportional sharing method to allocate the losses among the transmission users especially for industry consumers. The IEEE 14- and 30 bus test system is used to compare the proposed method with existing method. The results showed that the proposed method provided a scheme better in allocating the cost of transmission loss, which could encourage the users to minimize the losses.
