The article deals with the impact of transformation of professional competencies on energy efficiency of the structural divisions of railway transport. The analysis of existing trends in the development of professional competencies in the field of energy saving and energy efficiency improvement in the context of active digital transformation is carried out, as a result of which the authors focus on additional professional education. Approaches to the quantitative and qualitative assessment of the impact of competence transformation on energy efficiency are considered, including historical and external benchmarking, as well as cluster analysis, and their advantages and disadvantages are described. An enlarged algorithm for evaluating the energy efficiency of enterprises is formed, taking into account the transformation of competencies. As initial data, the authors consider the energy efficiency indicators of structural divisions in relation to production and climate factors and the results of a survey of specialists. It is concluded that it is necessary to apply a comprehensive approach to assessing the transformation of competencies, which will effectively solve management tasks in this area, depending on the specifics of economic activity of a structural unit, the relative level of its energy intensity and other technological and socio-economic conditions.

The equipment energy efficiency improvement policy (EEEIP) is one of the important measures of energy conservation and emission reduction in various countries. However, due to the simultaneous implementation of variety policies, the effect of the single policy cannot be clearly reflected. In this paper, a method of identification and evaluation of EEEIP was proposed, and the application was verified by analyzing the example of EEEIP in Japan (Top Runner policy, TRP). Firstly, through the factor decomposition model, this paper studied the energy conservation and emission reduction potential of this policy area in Japan. Then, the TRP was identified by using moving windows and correlation analysis, and the impact of specific equipment in TRP was analyzed. Finally, through the calculation of the rebound effect of the carbon footprint (REC), this paper analyzed the energy consumption and emission reduction effects of TRP in the short-term and whole life cycle. It showed that the policy has a good effect in tertiary industry and transportation, while the effect in residential is poor. For life cycle, the TRP of air conditioning and passenger car can bring better CO2 emission reduction effect, but the emission reduction effect of lighting is basically offset.

This paper investigates the economic impact of an energy efficiency improvement policy on electricity-intensive firms in Ghana. The policy imposed a penalty on these electricity-intensive firms, which are referred to as special load tariff (SLT) customers, when their power factor was below 90%. This paper applies the regression discontinuity design (RDD) to the panel data of these SLTs ranging from 1994 to 2012, excluding those years characterized by energy crisis. The results show adverse impacts of the policy on the employment and salary levels of the firms in the long run, in particular, the small- and medium–voltage firms. The results indicate that small- and medium–voltage firms are economically vulnerable to the penalty policy in the long run and recommend two policies to overcome this challenge. Firstly, the penalty for power factor improvement should not be imposed identically across firms with different voltage levels. Secondly, firms that satisfy the power factor standard should receive subsidies to improve their competitiveness in the market.

Energy efficiency improvement in industrial companies is an essential prerequisite for the enhancement of their competitive positions in the national and global markets. Yet, the approaches currently employed in respect of the energy management do not fully utilize the innovative potential of energy technologies to achieve strategic goals. One way to further develop energy management is theoretical justification of the use of new approaches based on the suggested concept of the energy saving and energy efficiency processes’ positioning in the system of a company’s management priorities. In this article, we consider the applied use of the developed conceptual approach from the perspective of the energy saving and energy efficiency program development at the company. The main purpose of this paper is to justify the relations between energy management and strategic decision making in industrial companies. The results of the research conducted, firstly, make a certain contribution into the research of strategic multiple benefits of energy efficiency in a company; secondly, they expand understanding of the impact of energy saving and energy efficiency improvement on the achievement of operational, tactical and strategic results of the company’s activities; thirdly, they provide methodological decision support for the development of energy saving and energy efficiency programs taking into account the management and organizational barriers.

This study was conducted to identify the strategies used by operators to provide a high level of service. The research distinguishes between punctuality and regularity of service and proposes that metro passengers primarily value regularity. The focus of this research is not on incident prevention, but on strategies that can be implemented after an incident to restore service swiftly and to minimize delay. The research identifies the recovery strategies used by six metros and summarizes advantages and disadvantages of these strategies. The influence of the type of delay on the choice of strategy is described. Similarly, the impact of constraints such as line length, service frequency, and passenger crowding on the effectiveness of each strategy is also discussed. It was found that it was generally sufficient to distinguish minor incidents, slow-moving delays, and major incidents. A case study shows that those metros with higher inbuilt flexibility can return more easily to normal service. This finding will have implications for metro management. The research has been carried out by the Railway Technology Strategy Centre at Imperial College London in collaboration with the Community of Metros benchmarking group. The performances and service qualities of six metros (three European, two American, and one Asian) have been analyzed and compared. The study consists of a quantitative analysis of the performance of two lines from each metro, together with a more qualitative assessment of the strategies used to optimize performance, through structured interviews with key operational and managerial staff.

The energy efficiency of the Russian economy lags far behind the developed countries of the world that worsens its socio-economic development. To increase energy efficiency, it is necessary to introduce innovative solutions that require large investments. The object of the research is the economy of the Irkutsk region that energy efficiency growth, being the most important priority of socio-economic development, is of particular relevance due to its high energy intensity. The purpose of the study is to perform an energy-economic analysis of the Irkutsk region, and to determine the impact of investment on the energy efficiency growth. The methodological approach developed by the authors and used in this research is based on the balance and statistical methods. In course of the research, retrospective fuel and energy balances (FEB) of the Irkutsk region have been developed, and the energy efficiency indicators have been calculated on their basis. The main directions for the fuller use of the fuel and energy resources (FER) have been identified, the implementation of which will significantly increase the energy efficiency indicators. It will require an increase in investments in the fuel and energy complex (FEC) by 1.7-2 times by 2030 as compared to 2016.

This research presents an energy efficiency improvement solution for supermarkets with the use of low-E glass doors for open refrigerators and a digital semi-hermetic compressor to fix the speed of semi-hermetic compressors. The impact of a door’s installation causes its load to be reduced by 40%, and the compressor shuts down frequently, which decreases its lifetime. In order to ensure that energy-saving solutions do not affect maintenance costs, the installation of a digital semi-hermetic compressor is proposed to lower costs and save energy. Our economic results from tests carried out at a 3000 square meter supermarket, which was open from 6:00 am to 12:00 am and in which we installed 82 doors on 15 open refrigerators, showed a 1.1-year payback period with an energy saving rate of 192,220 kWh/year for store No.1 (R22) and in which we installed 80 doors on 15 open refrigerators, showed a 1.4-year payback period with an energy saving rate of 171,185 kWh/year for store No.2 (R404A). The energy-saving effects of the digital semi-hermetic compressor, which fixes the speed of the semi-compressor and solves the problem of impact from fridge door installation, showed a 2.9-year payback period with an energy saving rate of 26,890 kWh/year for store No.1 (R22) and showed a 2.9-year payback period with an energy saving rate of 26,571 kWh/year for store No.2 (R404A). The results of store No.1 (R22) and store No.2 (R404A) showed no differences. This research is an extension of an energy-saving project that can be carried out on a continuous basis, increasing the efficiency of energy use and being a sustainable source of energy conservation.

Environmental safety and the rational use of natural resources are among pressing present-day problems. Energy efficiency improvement is an important constituent of energy policies in many countries. This article examines the impact of the “rebound effect” on improving the energy efficiency of environmental safety programs implement-d at federal and municipal levels. There is still no consensus on how to take the “rebound effect” into account and whether it should be considered at all. Paradoxically, the “rebound effect” is the unintended side effect of energy efficiency activities. In this paper, different types of this effect are considered. The “direct assessment” method, based on the non-linear relationship between energy consumption and efficiency, is used to assess the “rebound effect” produced on individual household appliances. The factors hindering the implementation of energy efficiency activities are also identified. Having analyzed the impact of the effect on different sectors of economy, we can conclude that the most pronounced “rebound effect” is observed in the housing sector. Consequently, if we consider a major energy efficient renovation, we have to take account of the “rebound effect” caused by new energy saving activities.

Saving energy and looking for alternative energy sources are both elements of energy efficiency management, which is still a significant challenge for many companies around the world. Unfortunately, energy efficiency in companies is often equated only with thermo-modernization or the replacement of lighting. However, one of the most important methods of improving energy use in manufacturing companies may be the modernization of the machine park. Therefore, the main purpose of the paper was to investigate the activities of enterprises in the field of the modernization of machines and the impact of this on the actual improvement of energy efficiency. The modernization of machines in production plants is understood as adapting new parts to the old device or rebuilding the machine in such a way that it can cooperate with its new subassemblies. Companies usually decide to modernize the machinery fleet, bearing in mind the benefits of production efficiency, and they do not always combine this modernization with energy efficiency improvement measures. This is confirmed by the presented results of a survey conducted with a group of 111 manufacturing companies. Several important statistical relationships in the studied area were indicated by conducting an analysis based on the chi-square test and, in some cases, by clarifying the results of the z-test with the Bonferroni correction.
