Resource Saving

Consider ways to stimulate heat and energy conservation in Ukraine and other countries, based on an analysis of the legal framework and practical experience. Review and analysis of the Energy Strategy of Ukraine for the period up to 2035 “Security, Energy Efficiency, Competitiveness”, Laws of Ukraine “On Energy Saving”, “On Energy Efficiency Fund”. Review and analysis of the practical experience of applying different ways of stimulating energy saving, improving the efficiency of use of fuel and energy resources by economic entities, consumers in the housing sector in Ukraine and other countries. The ways of stimulation of heat and energy conservation in Ukraine are proposed, which envisage both the system of financing of projects of resource saving and ways of informing consumers about the energy efficiency of new equipment (through marking), buildings, households. The main directions to be developed for efficient management of energy efficiency projects, in particular, the efficient functioning of district heating; combined production of thermal and electric energy; use of local renewable energy resources; introduction of resource-saving eco-friendly technologies. The legislation, which provides financial and informational ways of stimulating energy and heat conservation, as well as ways of financially filling the energy efficiency fund in Ukraine and the corresponding funds in other countries, is considered. The operation of the Energy Efficiency Fund is necessary for the provision of tax benefits, subsidies (targeted state and others), irrevocable appropriations for various types of energy conservation works, for the introduction of new types of energy saving equipment and technologies.

The relevance of the research topic is due to the study of the important problem of improving the energy efficiency of the economy and the meso and micro levels. In the conditions of the development of an innovative economy, energy saving becomes one of the main factors for increasing the economic efficiency and economic security of industrial enterprises and complexes. The article discusses the main aspects of the organization of energy-saving environmental production systems. The factors affecting the energy efficiency of the production process from the standpoint of logistics, including the processes of storage, storage and transportation of products within an industrial enterprise, are summarized. As a criterion of energy saving in logistics chains, the coefficient of consumption of energy resources spent per unit of production is given. The analysis of the dynamics of fuel and energy costs per unit of output by the types of activities of petrochemical plants of the Republic of Tatarstan was carried out. The specificity of the level of fuel and energy costs by type of activity is shown, depending on the specifics of production and products. The variation of energy consumption data by types of petrochemical production activities for 10 years has been calculated. The prospects for reducing the energy intensity of petrochemical enterprises in the context of the liberalization of the market of electric energy and power are considered. The materials of the study can be used in managing the development of the real sector of the economy, the service sector, both at the enterprise services level and in government structures. In addition, the proposed methodology is appropriate for assessing the level of resource-saving production, building innovative energy-saving development strategies, and developing a mechanism for targeted actions for the rational use of resources.

The process of energy saving and its components in the production sphere is investigated. It is determined, that the national policy of energy saving deals with the increase of fuel-energy recourses extraction, application of non-conventional renewal energy sources, maximum usage of energy saving potential, as well as adapting of the national law system to the EU standards. The need to make alterations in the Energy Strategy of Ukraine till 2030 concerning the increase of importance of energy saving control processes and energy efficiency of different types of recourses during the period of the Fourth energy-package implementation in the European Union is substantiated. It is shown, that successful control of the energy saving processes in the production sphere can be obtained by energy efficiency resulting in the decrease of electric energy consumption per product during production, the cost of the renewal energy sources and noxious substances wastes. It is noted, that according to the law of Ukraine «On energy efficiency» it is expected, that energy efficiency specifies the equipment, technologies, production or system on the whole and it indicates the level of energy resources consumption per product production. The increase of energy efficiency is obtained by the introduction of some organizational and engineering measures in the production process. Energy efficiency and energy saving are interrelated processes, which testify the level of efficiency the fuel-energy resources consumption per final production unit. Energy efficiency describes the quality processes in energy sources application, having both political and social problems, and require the implementation of new society approaches to the application of energy recourses. It is noted that the Energy Union envisages the creation of a single architecture of the electricity market, which should promote the market integration of electricity generated by renewable energy sources (RER) and increase the energy efficiency of the European economy.

AbstractBiomass is one of the most abundant renewable energy resources on the earth, which is also considered as one of the most promising alternatives to traditional fuel energy. In recent years, microbial fuel cell (MFC) which can directly convert the chemical energy from organic compounds into electric energy has been developed. By using MFC, biomass energy could be directly harvested with the form of electricity, the most convenient, wide-spread, and clean energy. Therefore, MFC was considered as another promising way to harness the sustainable energies in biomass and added new dimension to the biomass energy industry. In this review, the pretreatment methods for biomass towards electricity harvesting with MFC, and the microorganisms utilized in biomass-fueled MFC were summarized. Further, strategies for improving the performance of biomass-fueled MFC as well as future perspectives were highlighted.

The University

At the University of Szeged, as the greenest University of Hungary, the sustainability project is built on two pillars. One of them is based on events and communication campaigns held regularly for the University citizens to prompt environmental-conscious behaviour, whereas the other is built on technological developments and on the extensive use of renewable energy resources. Thus the development of built environment and social responsibility both support the adequacy to sustainability requirements. The spreading of the effective solutions to making more and more buildings of the University energy efficient, numerous investments using renewable energy are also responsible for the decrease of the natural energy use of the institution contrary to the fact that the number of the buildings of the University of Szeged is continually increasing. It can be stated that the University of Szeged is committed to using renewable energy which is taken into consideration of each investment planning. The following examples confirm it: using geothermal cascade system for heating and cooling of five university bulidings, solar panels on 24 builidings and a unique technology of using the heat of wastewater to cool and heat one of the main bulidings of the university, namely the Study and Information Centre.

Lean Tools

Energy cost is significant in many of the manufacturing activities. The efficiency of energy use is quiet low as there are substantial visible and hidden losses. Visible losses can be easily identified and corrective action can be taken. However hidden and indirect losses form a sizeable portion of the losses. Identifying these losses is not easy and requires an integrated approach which includes thorough study of process, operations and their interactions with energy use. Industries across sectors have implemented lean management principles which target various wastes occurring in the plant. This paper discusses case studies which highlight the exploitation of lean tools as a means for unearthing hidden energy saving potential that often go unnoticed. In addition to the energy savings which results in improved profits and competitiveness, the approach also aids the industry to pursue a path of sustainable manufacturing.
