In recent years, the industry's responsibility to join in sustainable manufacturing becomes huge, while innovating sustainability has been a new trend. Industrial enterprises are pursuing energy reduction to meet future needs for sustainable globalization and government legislations for green manufacturing. To run a manufacturing line in an energy-efficient manner, an energy-oriented maintenance methodology is developed. At the machine layer, the multi-attribute model (MAM) method is extended by modeling the energy attribute. Preventive maintenance (PM) intervals of each machine are dynamically scheduled according to the machine deterioration, maintenance effects, and environmental conditions. At the system layer, a novel energy saving window (ESW) policy is proposed to reduce energy for the whole line. Energy consumption interactivities, batch production characteristics, and system-layer maintenance opportunities are comprehensively considered. Real-time choice of PM adjustments is scheduled by comparing the energy savings of advanced PM and delayed PM. The results prove the energy reduction achieved by this MAM-ESW methodology. It effectively utilizes standby power, reduces energy consumption, avoids manufacturing breakdown, and decreases scheduling complexity. Furthermore, this energy-oriented maintenance framework can be applied not only in the automotive industry but also for a broader range of manufacturing domains such as the aerospace, semiconductor, and chemical industries.

The study used general and special methods, including abstract and logical (to outline the main factors, influencing the characteristics of energy saving in agricultural enterprises, for the author’s interpretation of the energy saving system in agricultural enterprises), deductive (to analyse the dynamics and areas of economic efficiency level increase of energy saving system); generalization (in the study of the possibility of implementing the latest technologies aimed to improve the energy saving system in agricultural enterprises). Findings. It is established that agricultural industries have a number of features, in particular: use energy for production, generate it. This feature is based on the fact that in the production process there are three fundamentally different types of energy: anthropotechnogenic (fossil); solar and soil energy. It was found that the process of energy conservation in agriculture should be formed by reducing fossil energy sources and by making fuller use of renewable solar energy and soil energy potential. An important feature of agriculture has been identified, which lies in its significant level of spatial dispersion, which causes significant costs for transport services of production processes and logistics. There is a significant difference in the principles of energy consumption, fossil energy is the main in industry and in agriculture - it plays a supporting role. There, natural energy forms the biological mass (harvest, live mass of animals). The author’s interpretation of the concept “energy saving of agricultural enterprises” is offered, which includes a system of measures (organizational, economic, technical and technological, ecological, legal and operational), coordinated action of which should be aimed at the rational use of energy in the process of agricultural production. The indicators of the group of economic analysis of energy saving in agriculture are determined: total energy capacity; energy armament; energy supply; electrical equipment of labour, etc. The key stages of energy saving research and tasks in agricultural enterprises are clarified. Grouping of methods of research of energy saving is offered. Originality. The author’s interpretation of the concept of “energy saving of agricultural enterprises”, definition of key stages of energy saving research and systematization of appropriate methods were further developed.

The aim of the article is to study the main approaches and develop a methodology for assessing the efficiency of enterprises in the transition to alternative (helio) energy sources. The concepts of the ʻenergy efficiencyʼ and the ʻenergy savingʼ are the main characteristics of efficient use of energy resources. The term "energy efficiency" is a resultant indicator that captures the achieved level of efficiency of consumption and use of fuel and energy resources in the process of enterprise activity. The concept of ʻenergy savingʼ is a process indicator that indicates the way to achieve energy efficiency (implementation of a set of measures) of resource conservation in the enterprise. It is established that the key indicator for assessing the efficiency of the energy consumption system is the energy intensity indicator, the reduction of which should be considered as one of the main tasks in order to increase the efficiency of the enterprise. It is proved that the transition of an industrial enterprise to alternative (helio) energy sources is a guarantee of reducing its energy intensity. Therefore, the issues of implementation of energy saving programs are relevant for industrial enterprises. Energy saving measures will help reduce costs at the enterprise, conserve natural resources. The study found that solar energy in Ukraine in 2019 shows a bright positive trend. The ʻgreen tariffʼ was officially received by stations with a total capacity of 3537.382 MW, which is 5.48 times higher than in 2018. In 2019, the capacity of industrial solar power plants was put into operation 3.5 times more than in all previous years. The amount of electricity produced by industrial plants, in 2019, is 2.66 times higher than in 2018. The transition to alternative energy sources for industrial enterprises is a rather complex technological task, which requires methodological developments for the optimization of energy resources to maximize the efficiency of enterprises. A method for assessing the efficiency of the enterprise in its transition to alternative (helio) energy sources based on the use of production functions and factor models, which include the entire evaluation apparatus and a set of indicators of efficiency (appropriateness) of resource use, i.e. resource conservation. This method of assessing the performance of the enterprise is based on the use of the Cobb-Douglas production function, which allows to justify the decision on the feasibility of the use of production resources and to adjust the deviations of the spent resources from the normative values.
