A complex of tasks that can be solved using mathematical models of the dependence of consumed energy resources on influencing factors are considered in the article. The main type of model for industrial consumers with a simple relationship between energy and technology, is the one-factor model “consumed energy resource-volume of output”. For industrial consumers with a complex relationship between energy and technology, the mathematical model of the dependence of energy resources on technology is determined by several factors. Methods for assessing the current state of energy efficiency, as well as predicting it for the future in the context of the introduction of energy saving measures and changes in the production program were proposed.

The paper is an overview of the themes selected for the main topic of the issue, their relevance and the validity of the research conducted in the journal for the legislation and law enforcement practice in the context of the industrial revolution and the need for greening modern business. In addition, the author explains the editorial board’s choice of the main topic of the next issue of the legal journal of Volgograd State University “LegalConcept = Legal paradigm” under the title “The right to protect human health and an environmentally friendly business environment”. The objective need for the technology development of the intensive involvement of the potential of Russian environmental entrepreneurship in the industrial revolution processes is substantiated. The most important tasks are identified, which are addressed by the developments in the legal regulation of the digitalization processes of environmental entrepreneurship in Russia. The author lists a set of measures that, in the author’s opinion, are of primary importance for ensuring these processes. It is noted that the topic proposed for development is closely related to the formation of scientific and technological foundations that ensure the economic growth and social development of the Russian Federation. The state of scientific and technological progress achieved by modern society is manifested by the widespread use of digital technologies in various areas of production, business management, the provision of services in medicine, the banking sector, and the social sphere. It is proved that comfortable life, the security of the processes through qualitatively new regulatory approaches, the state security, including cybersecurity, overcoming the adverse effects due to natural disasters, as well as the introduction of biotechnology, entailing the appearance of unknown infectious diseases and viruses, preventing man-made disasters – these and many other goals and objectives can’t be achieved now or get a solution without the use of digital information technologies. It is also impossible to ignore the studies of the society and nature interaction, the cross-sectoral impact of modern technology in the field of renewable energy, the turnover of energy resources and energy efficiency improvement on the environment, the life and health of citizens, the public and state institutions designed to participate in the protection of the environment which corresponds to the solution of the specific objectives set in the Strategy for Scientific and Technological Development of the Russian Federation. According to the author, the studies of the dynamics of interaction between the economic and legal institutions in the field of renewable energy development, the turnover of energy resources, and energy efficiency improvement will contribute to the expansion in renewable energy as one of the “green” sectors of the economy.

The Netherlands Ministry of Defence (MoD) has issued an Operational Energy Strategy (OES) with ambition targets for energy independence and improvement of energy efficiency during the life time of naval platforms. A target is given in 2030 of 20 % reduced dependence on fossil fuels and in 2050 of 70 % reduced dependence on fossil fuels, compared to 2010. More stringent environmental emission (NOx, CO2, etc.) requirements are to be expected as a result from IMO and (local) political regulations. In the last decades the power consumption on board of naval platforms increased substantially as well as the complexity of integrated energy systems. Market surveys shows that the evolution of commercial green technologies are promising but have to be demonstrated in the coming years on low power and energy levels. They will not be de-risked in depth or well proven to be successful in time to be selected for the Royal Netherlands Navy (RNLN) new naval projects (2019 – 2025). Furthermore, new technologies as energy resources and carriers (H2, LNG, methanol, power-to-liquid (PTL), etc.) or new system technologies (DC on high voltage level, fuel cell systems, waste energy recovery, etc.) require a new approach for integration aspects like hazard and safety cases and energy efficiency. This is because the energy demand on board of naval platforms in several military operational modes differ from the merchant and off-shore branch. In this paper an approach for an adaptable energy platform is described to design a new naval platform based on nowadays proven technology as fossil fuels that can be transformed during life time that can fulfill the expectations and requirements of the coming decades (non-fossil fuels, zero emission, improved energy efficiency). Aspects as a naval energy index as reference will be discussed as well as an evaluation of new technologies for new naval platform integration design parameters, such as power or energy demands, consequences of energy resources, energy control as well as build in ship construction safety measures.

The management of natural resources, especially energy resources, is a challenge for today's society. For this reason, Energy Efficiency (E.E.) is considered as a key tool to promote economic growth, reduce the consumption of natural energy resources, and help to solve multiple environmental impacts. In this study, a systematic mapping of the literature concerning E.E. is carried out. Based on the research questions formulated in the systematic mapping, a knowledge gap is identified, which is that the problems linked to energy are not being addressed from a systemic and interdisciplinary paradigm. This calls for the development of methodological, sociological, and technological processes that allow understanding of E.E. from a systemic perspective. Finally, the basis for an alternative vision of E.E. in Colombia is proposed, which tends towards the sustainability and conservation of natural energy resources.

The article gives the analysis of resource saving and energy efficiency of the enterprises of water supply and waste water services of the State Unitary Enterprise “St. Petersburg Vodokanal”. There has been evaluated the consumption of electrical energy by the enterprise. The main methods of energy resources management (creating a system of rational consumption and saving of energy resources, using energy-efficient materials, equipment and technologies, identifying the potential of energy-saving measures at operating facilities) have been determined. The priority directions for reducing the production energy intensity in the water supply processes have been defined. An algorithm is proposed that includes the processes of collecting, modeling, structuring information, as well as developing an optimal solution for an enterprise. A model for optimizing work in water supply processes is presented, software products are considered that allow to control the processes of energy saving and energy efficiency. The most promising software products for their introducing them into practice of the enterprise have been identified, including General Electric Intelligent Platforms CSense. A plan for the sequential implementation of the software product into operation at the enterprise is presented. The dynamics of electricity consumption at the enterprise, the structure of energy consumption are illustrated. It is noted that the most significant contribution to the amount of energy consumption is made by the technological processes of water intake and supply. It has been substantiated that the most energy-consuming process for the enterprise (Water Supply Branch of the State Unitary Enterprise St. Petersburg Vodokanal) is replacement or maintenance of pumping equipment. The components of energy conservation of the enterprise under study are the partial regulation and automation of processes.

In geographical areas with cold climates, large, massively constructed industrial and warehouse buildings and logistics complexes are large consumers of energy resources. The great height and large contained volumes of the premises, the presence of a significant number of doors, and building configurations that include many transport corridors all require the use of air-thermal curtains to increase the energy efficiency of the buildings’ heating, ventilating, and air-conditioning (HVAC) systems, which commonly produce several thousand kilowatts of thermal power. Optimization of air curtains can improve the microclimates of the premises, achieve savings in the initial construction costs, and also reduce energy consumption during operation by 10–20%.
