Based on the energy consumption and the output value data of the 6 small heavy industrial enterprises during 2007-2011 in Shanghai, we calculated comprehensive energy consumption, carbon emissions, carbon intensity and energy intensity of these enterprises. It been found that the comprehensive energy consumption and the carbon emissions of the 6 small enterprises are in a fluctuating growth trend but the energy intensity and the carbon intensity show a trend of fluctuating downward. The energy intensity and the carbon intensity of the small enterprises are much larger than the average of the two whole industries in Shanghai. We analyzed the correlation coefficients between the output value and the energy consumption as well as between the output value and the carbon emissions. The results show that the comprehensive energy consumption and the carbon emissions have positive correlation as well as the carbon emissions and the output value.

The article substantiates the necessity and relevance of the introduction of progressive energy efficiency systems at industrial enterprises. It is shown that in Ukraine in 2020 only 43.1% of energy resources are used efficiently, according to the data of the energy efficiency rating. In 2019, this figure was higher - 54%. The analysis of the use of energy resources in industry, services, agriculture and the housing sector in Ukraine, as well as in the countries of the European Union. The issues of organizing energy efficiency benchmarking for industrial enterprises of Ukraine are considered. The main attention is paid to an integrated approach, which consists in creating a regulatory framework and organizing information support during benchmarking. The experience of the EU countries in solving the problem of technical regulation of energy efficiency benchmarking and the possibility of its use in international entrepreneurship is considered. Only the main stages of energy saving benchmarking are considered in detail, which include: selection of a benchmark, comparison and assessment, positioning of the research object and determination of leaders and outsiders, grouping benchmarking partners by energy efficiency level, identification of the gap, identification of the causes of inefficient energy consumption, determination of the scale and nature of the problem. The introduction of an energy efficiency benchmarking system on a regular basis as a control and planning subsystem as part of an energy management system will make it possible to track changes in the energy efficiency indicators of the production system and its structural objects, the level of energy efficiency over time, negative trends and causes of their occurrence, to assess the effectiveness of adaptation of the best principles of efficient energy consumption in own conditions and the effectiveness of the implementation of energy-saving measures, which will contribute to the continuous improvement of the production system and its facilities.

Effective control of production operations usually leads to improved energy efficiency in manufacturing systems. In this paper, we investigate energy consumption reduction in production systems by scheduling of machine startup and shutdown. Specifically, we consider serial production lines with finite buffers and machines having Bernoulli reliability model. This machine reliability model is applicable in production situations, where the downtime is relatively short and comparable to machine cycle time (e.g., automotive paint shops and general assembly). Using transient analysis of the systems at hand, an analytical performance evaluation technique is developed for Bernoulli serial lines with time-dependent machine efficiencies. In addition, trade-off between productivity and energy-efficiency in production systems is discussed and the energy-efficient production problem is formulated as a constrained optimization problem. The effects and practical implications of operations schedule are demonstrated using a numerical study on automotive paint shop operations.

The current global population growth forecast carries with it a global increase in demand for food. In order to meet this demand, it is necessary to increase production, which requires an increase in energy consumption. However, forecasted energy production growth is insufficient and traditional sources of energy are limited; hence, it is necessary to strive for greater energy efficiency in food production systems. The study aimed to compare the economic energy efficiency of food production systems in selected countries and identify the sources of diversification in this field. As a measure of energy efficiency, the indicators of the energy intensity of food production were used in this study. To calculate these indicators, a method based on input-output life-cycle assessment assumptions was used, which enables researchers to obtain fully comparable results between countries. The study showed that despite an increase in energy consumption in the food production systems of the analyzed countries by an average of 27%, from 19.3 EJ to 24.5 EJ, from 2000 to 2014, their energy intensity decreased, on average, by more than 18%, from 8.5 MJ/USD to 6.9 MJ/USD. This means that energy efficiency improvements are possible even under conditions of increased energy consumption, which in turn, means that food production can increase significantly. In the case of developed countries, the main inefficiencies are found in agricultural production, while in developing countries, they are observed in the food industry. Decision-makers should also pay attention to the high level of energy intensity that results from the supply of inputs to agriculture and the food industry because there is great potential for the improvement of energy efficiency in this field, especially because energy consumption associated with supply constitutes a major part of total consumption in the food production systems of developed countries.

Energy efficiency of production systems and of the product itself has grown to a critical competitive factor. Besides the manufacturer’s monetary motivation there are increasing incentives to meet customers’ expectations regarding lifecycle cost and the ecological footprint of products. That neo-ecology, as one megatrend, leads to a new business moral resulting in an energy optimization of the whole product life cycle in terms of resource and energy input. There is a plenty of measures to reduce the energy consumption of a production system and thus to increase its efficiency. To do so companies do not have to develop proprietary solutions for their production sites but can draw on a large pool of measures. However, in practice, many energy optimization measures are unknown to their energy managers. This is mainly owing to the fact that there is no standardized categorization for energy optimization potentials yet. In addition, many efficiency deficits remain undetected as a result of a non-existing efficient methodology for finding energy consumption optimization measures. The domain of information retrieval addresses this issue, as it is able to provide documents matching the user’s information demand. Nevertheless, search queries have to be sufficiently well known in order to gain adequate results. In this paper we show how ontologies can be used to support the user in defining search queries and finding optimization measures efficiently. As formal and explicit specifications of shared conceptualizations, ontologies offer the possibility to represent relevant parts of knowledge in a standardized, machine-readable manner. Therefore, ontologies improve upon data models, which are mainly used for single applications. For the purpose of energy efficiency in production environments, we provide both a methodology to build ontologies for describing energy saving measures and illustrate the application for explicit energy efficiency optimization measures.

Energy management is an independent type of professional activity aimed at achieving in the course of any business activity of an enterprise operating in market conditions, reducing costs by improving energy efficiency. Energy management includes a set of measures aimed at saving energy resources: monitoring of energy consumption and energy intensity of products, development of energy budgets, analysis of existing indicators as a basis for drawing up new budgets, development of energy policy, planning of new energy saving measures. This article describes the methodology for determining the energy intensity of products for industrial enterprises, namely energy intensity indicators. These values include: norms of consumption of heat and electricity per unit of industrial production, as well as norms of consumption of fuel and electricity for the supply of heat to the boiler plant of the enterprise. These numbers are indicators of energy efficiency that need to be calculated when implementing energy management systems at enterprises. They are the benchmarks by which the current state of energy efficiency is assessed and planned for the future, taking into account changes in output, implementation or dismantling of equipment, implementation of energy-saving measures, etc. The article shows the calculation of energy consumption of products by the example of a grain elevator.
