Purpose. In modern conditions of energy consumption growth and a rapid increase in energy prices the actual problem is the development and implementation of energy efficiency programs and resource-saving conversion in to a source to provide the needs of industry and municipal power. The paper aims to solve the urgent problem of energy saving and efficient use of fuel-energy ones and heat supply system optimization on the basis of Uman National University of Horticulture (UNUH). Methodology. The work investigated the process of heating and hot water supply in the course of 2007-2015 years. Implementation of current problems of energy saving is grounded on the scientific-practical and efficient assurance of fuel and energy usage. At the same time energy-saving technologies are viewed as a priority direction of the energy sector development, reduction of man-induced impact on the environment and as a way of improving the competitiveness of the national economy. Findings. Statistical data acquisition and analyzing of gas flow and outside air temperature for nine years was carried out. On the basis of this analysis, the problem was identified and specific targets for its solutions were set. Originality. Scientific novelty lies in solving the problem of energy saving and efficient use of fuel resources in Ukraine through the use of a systematic approach, the methodology development of efficient use of different fuels and optimization of local heating operation, applying contemporary automation and control systems. Firstly it was in detail analyzed and conducted the comprehensive assessment of various factors influence on energy conservation. It takes into account the human factor, professionalism and responsibility of the operators of boilers and their superiors, as well as the relevant control services. Practical value. For UNUH campus hybrid use of solid fuel and gas boilers was carried out. Decentralization of the university heating system has been conducted through the restoration of 350 individual heating systems in residential buildings, remote departments and campus dormitories. The conclusions propose the list of activities upon the real economy of fuel and energy resources, and measures to overcome the economic and political crisis in the country.

The paper represents the analysis, which has helped to establish the usage of gas hydrate technologies in the methane conversion. This gas could be obtained in different ways. Possibilities and sources for the gas obtaining have been demonstrated. Use of other environmentally friendly sources to support operation in such systems in terms of joint energy complex has been considered. The necessary kinetic connections to provide operational sustainability of all the constituents have been given. The approach helps evaluate quantitatively the priority of its physicochemical transformations to obtain gas hydrates artificially. It is possible to transport methane at considerable distances when it is solidified. Actually, in this case there is no necessity to build costly compressor stations and pipelines for its transportation to consumers. The approach is extremely important for mining regions as it helps prolong the operating period and working out of the abandoned and off-balance coal reserves. In this case, it is proposed to apply special gasification technologies tending to maximum methane recovery. The proposed solutions give the possibility to define the trends of our further research. They will be highlighted in the following authors’ studies.

The health of the ocean, central to human well-being, has now reached a critical point. Most fish stocks are overexploited, climate change and increased dissolved carbon dioxide are changing ocean chemistry and disrupting species throughout food webs, and the fundamental capacity of the ocean to regulate the climate has been altered. However, key technical, organizational, and conceptual scientific barriers have prevented the identification of policy levers for sustainability and transformative action. Here, we recommend key strategies to address these challenges, including (1) stronger integration of sciences and (2) ocean-observing systems, (3) improved science-policy interfaces, (4) new partnerships supported by (5) a new ocean-climate finance system, and (6) improved ocean literacy and education to modify social norms and behaviors. Adopting these strategies could help establish ocean science as a key foundation of broader sustainability transformations.

With rapid growth in the number of personal motor vehicles, Indian cities have been facing increasing congestion and worsening air quality. Yet until early 2005 little attention was paid to this problem, and remedial measures were focused largely on overpasses and new roadway capacity. Only Delhi, Calcutta, and Chennai had built functioning metro rail systems. However, by the second half of 2006, barely a year and a half later, the situation changed considerably, and public transport became the focus of attention in most large and medium-sized cities. This paper looks at the national initiatives that helped bring about those changes. The adoption of a national urban transport policy along with the launching of a national urban renewal mission with a sizable commitment of funds helped focus attention on improving public transportation. These were supplemented by a series of well-conceived and -planned initiatives, again led by the national government, to generate more widespread awareness of urban mobility problems and how they could be successfully addressed. The results were visible in a mere 18 months, by which time several cities had already formulated plans for significantly improved public transport and the first incremental phase of what will be India's first bus rapid transit system had become operational.

The article explores the problem of changing the worldview of mankind and the transition to the concept of sustainable development, which requires harmonization of the economic, environmental and social component to ensure the life of modern generations without prejudice to future ones. The conditions for the emergence of the concept of sustainable development and the progress of countries in achieving it using the index of achieving sustainable development goals are studied. A significant role in the process of studying the goals of sustainable development is given to ecologization of all life spheres, including the economy. The place of ecologization in the goals and objectives of sustainable development is determined, the interpretation of ecologization and the evolution of this concept are analyzed. The ecologization of economy has passed certain stages in its development and has led to the emergence of a new direction of science and practical activity − the ecological economy, which was formed at the intersection of economics and ecology. The main task of the ecological economy is to reduce the eco-destructive impact on the environment from human economic activity. Ecological economy adheres to the goals and objectives of sustainable development and is an integral part of a sustainable economy, reflecting its environmental aspect. Determination of the country's subsidiaries in ecologization of the economy is carried out using the green economy index, which reflects the degree of ecologization in various fields and has something in common with the index of achieving sustainable development goals. A comparative analysis of the indices of sustainable development and the green economy index, their values for Ukraine. The composition of the ecological (green) economy includes other ecologicallyoriented types of economy, each of which studies a certain direction of ecologization and reducing the eco-destructive impact on the environment. With the development of ecological thinking and a change in the worldview of mankind, the number of environmentally-oriented types of economy will increase as the number of scientific studies on environmental issues increases, which, in turn, will achieve the goals of sustainable development

<span lang="EN-US">A multi-point model predictive control (MPMPC) is widely used for many applications, including wind energy system (WES), notably enhanced power characteristics and oscillation regulation. In this work, MPMPC is adapted to condense the fatigue load of the WES and improve the lifetime of the turbine assembly. The lifetime examination is carried out by considering the three chief parameters: basic lifetime until failure, short-time damage equivalent loads (DELs), and lifetime DELs. The simulation study is performed for two cases: blade root bending moments and tower top bending. Further, fatigue load examination is demonstrated to analyze the effectiveness of the proposed controller. The observed results show that the lifetime analysis of the wind turbine system displayed more excellent characteristics, i.e., 49.50% greater than MPC. Also, the fatigue load mitigation showed greater magnitude due to the control action of the proposed controller, about 37.38% grander than MPC. Therefore, the attained outcomes exhibit outstanding performance compared with conventional controllers.</span>
