description Publicationkeyboard_double_arrow_right Article 2017 Russian FederationPublisher:Institute of Economics, Ural Branch of the Russian Academy of Sciences Authors: Belik, I. S.; Starodubets, N. V.; Yachmeneva, A. I.;One of the important problems of the environmental economics is the development of methodology for quantifying the assimilative capacity (AC) of a territory. The article analyzes the existing approaches to determining and assessing the AC of a territory. We justify the advantages of using the energy approach. The authors' method consists in using the maximum permissible energy load (MPEL) for quantitative assessment of the AC of a territory. MPEL is a value that the ecological and economic system can withstand for a long time without changing its properties. We determine MPEL on the basis of data on the ability of various categories of land to absorb greenhouse gases (GHG), as well as the specific GHG emissions per ton of conventional fuel. Further, we compare the calculated value of MPEL in fuel equivalents with the actual consumption of fuel resources for the needs of the national economy. These values ratio can serve as a standard for measuring and balancing the environmental and economic system. The authors have validated the described method on the example of the Sverdlovsk region, which is characterized by a high level of man's impact. Calculations show that the actual consumption of fossil fuels in the region exceeds MPEL. That indicates an imbalance in the ecological and economic system and may lead to further deterioration of the environmental quality in the region. The proposed methodological approach and calculations can be used when developing strategic planning documents for a territory, including its energy strategy. Рассмотрены существующие подходы к определению и оценке ассимиляционного потенциала территории. Предложен методический подход, особенностью, которого является применение для количественной оценки ассимиляционного потенциала территории предельно допустимой энергетической нагрузки, которую может на протяжении длительного времени переносить эколого-экономическая система без нарушения своих основных свойств. Апробация методики расчета предельно-допустимой энергетической нагрузки проведена на примере Свердловской области, территория которой подвергается высокому антропогенному воздействию.

Kirov; M.P. Galatsan;The analysis of the world electric-energy balance revealed the advantage of steam turbine plants. An increase in their efficiency through the improvement of the initial parameters runs into difficulties associated with creation of new materials. The efficiency increase that results from the final pressure reduction requires an improvement of the circulating water supply system. The aim of this work is to determine the effect of the water-cooling tower on the electric power station profitability. This goal was reached by the creation of a mathematical model of the water-cooling tower and turbine plant with a condenser connected to each other. The calculations were made for two types of cooling tower fill packing: asbestos cement sheets and mesh elements made of polyethylene. Further, according to it, the vapor condensation temperature was determined. The latter affects the vapor discharge in the condenser, the capacity of the turbine plant and the temperature of the cooling water at the condenser output, i.e. at the cooling tower input. The novelty of this work consisted of consideration of the interaction between the cooling tower and turbine plant. Significance of the obtained results lies in the fact that, taking into account the reciprocal influence of the turbine plant and cooling tower, the efficiency of the fill packing replacement turns out to be major comparatively to the case without considering this influence. The replacement of the fill packings the half-a-year average temperature of condensation will become lower by 2.34 °С, electricity production increases by 41.72 GWh.

For further information contact us at helpdesk@openaire.eudescription Publicationkeyboard_double_arrow_right Article 2023Publisher:MIRBIS Institute В материалах статьи представлены результаты исследования динамики, масштабов и структуры потребления энергоресурсов и электрической энергии в различных мировых континентах и крупнейших странах мира, с выявлением основных тенденций, а также оценкой факторов, влияющих на возникновение таких изменений. В материалах показано, что показатели различия объемов годового потребления энергоресурсов и электроэнергии странами мира могут достигать десяток или сотен крат, что связано с различием масштабов экономик и уровнем экономического развития. Построенная диаграмма показателей объемов потребления энергоресурсов и ВВП по ППС в странах мира позволяет констатировать факт прямой зависимости между данными показателями. Показано, что чем больше экономика производит валового внутреннего продукта, тем больше она обрабатывает сырья и оказывает услуг, что, следовательно, сопровождается потреблением энергетических ресурсов и электрической энергии. Различие характеристик общего потребления энергетических ресурсов и электрической энергии в странах мира определяет необходимость реализации дифференцированного подхода к управлению топливно-энергетическими комплексами и процессами повышения энергетической эффективности. В рамках статистических данных различных стран мира показано, что характеристики потребления первичных энергетических ресурсов, используемых на выработку электроэнергии значительно отличаются между собой не только в рамках какого-то статического периода, но и в динамике отражающей изменение структуры общего спроса в странах. В процессе развития энергетической политики различных стран мира необходимо учитывать ряд важнейших факторов, прежде всего связанных с масштабами потребления энергоресурсов, структурой ТЭР, динамикой изменения потребления энергоресурсов в различных периодах, а также с учетом факторов, влияющих на такую динамику. Качество формирования энергетической политики, нормативно-правовых актов регулирующих потребление энергоресурсов имеет прямое влияние на уровень экономического развития каждой страны мира и отдельного территориального образования. The article presents the results of a study of the dynamics, scale and structure of energy and electricity consumption in various continents and major countries of the world, identifying the main trends, as well as assessing the factors influencing the occurrence of such changes. The materials show that the indicators of the difference in the volume of annual consumption of energy resources and electricity by countries of the world can reach tens or hundreds of times, which is due to the difference in the scale of economies and the level of economic development. The constructed diagram of indicators of energy consumption and GDP by PPP in the countries of the world allows us to state a direct relationship between these indicators. It is shown that the more the economy produces gross domestic product, the more it processes raw materials and provides services, which, therefore, is accompanied by the consumption of energy resources and electrical energy. The difference in the characteristics of the total consumption of energy resources and electric energy in the countries of the world determines the need to implement a differentiated approach to the management of fuel and energy complexes and energy efficiency improvement processes. Within the framework of statistical data from various countries of the world, it is shown that the characteristics of consumption of primary energy resources used for electricity generation differ significantly not only within a static period, but also in dynamics reflecting changes in the structure of total demand in countries. In the process of developing energy policy in various countries of the world, it is necessary to take into account a number of important factors, primarily related to the scale of energy consumption, the structure of the fuel and energy complex, the dynamics of changes in energy consumption in different periods, as well as taking into account factors affecting such dynamics. The quality of the formation of energy policy, regulatory legal acts regulating the consumption of energy resources has a direct impact on the level of economic development of each country in the world and a separate territorial entity.

Считается, что основной причиной глобального потепления является технический прогресс. Техносферная деятельность человека приводит к росту содержания в атмосфере парниковых газов за счет все большего сжигания топлива, что является фактором, повышающим температуру. Климатические аномалии провоцируют социальные катаклизмы. Важнейшей задачей на современном этапе является снижение глобальных рисков и повышение безопасности людей. Эффективным инструментом повышения устойчивости среды обитания является строительства «зеленых» зданий. В данной статье выполнен аналитический обзор современной направленности работ в области «зеленого» строительства в России и в зарубежных странах. Рассмотрены основные принципы «зеленого» строительства, концептуальные основы зданий с низким энергопотреблением. Показано, что «зеленые» крыши и «зеленые» фасады являются важными элементами формирования экологически устойчивой архитектуры и энергосберегающего строительства. Рассмотрены проблемы повышения энергоэффективности при термореновации фасадов зданий. Рассмотрены принципы рейтинговой оценки в «зеленом» строительстве. Полученные результаты имеют важное практическое значение. Систематизация и обобщение данных по «зеленому» строительству позволяют наметить дальнейшие пути повышения энергоэффективности и экологической безопасности зданий и сооружений при решении актуальной проблемы повышения устойчивости среды обитания в градостроительстве и архитектуре. It is considered that technical progress is a basic reason of global warming. Activities of the person lead to growth of content in the atmosphere of greenhouse gases due to the increasing combustion of fuel that is the factor of increasing temperature. Climatic anomalies provoke social cataclysms. The major task at the present stage is decrease in global risks and increase in safety of people. The effective instrument of increase in sustainability is constructions of green buildings. In this article the analytical review of a modern direction of the green construction problem in Russia and in foreign countries is executed. The basic principles of a green construction, conceptual bases of buildings with low energy consumption are considered. It is specified that green roofs and green facades are important elements of ecologically steady architecture and energy-saving construction. Problems of increase in energy efficiency in case of thermorenovation of facades are considered. The principles of rating in a green construction are indicated. The received results have important practical value. Systematization and generalization of data on a green construction allow to plan further ways of increase in energy efficiency and ecological safety of buildings and structures in case of the solution of an urgent problem of increase in sustainability in town planning and architecture.

A variant of a sailing power plant is known that converts the energy of a wind flow into the energy of a water flow, which makes it possible to reduce the size of the energy converter, but its efficiency decreases, since part of the energy of the wind flow is spent on moving the sail installation, and there are also difficulties in transferring the generated energy to an external consumer . A variant of a ground-based sailing power plant is proposed, in which these problems are removed. The conducted experimental studies of models of ground-based sailing power plants have shown the operability of the elements included in the experimental installation, structural elements have been found that can be used in the implementation of a ground-based sailing installation. In order to determine the power that land-based sailing installations can develop, studies were carried out on the developed experimental installation to determine the magnitude of the forces on which the speed of movement of the sailing installation models depends. The results of these studies are presented in this article.

description Publicationkeyboard_double_arrow_right Article 2017 Russian FederationPublisher:Institute of Economics, Ural Branch of the Russian Academy of Sciences Authors: Belik, I. S.; Starodubets, N. V.; Yachmeneva, A. I.;One of the important problems of the environmental economics is the development of methodology for quantifying the assimilative capacity (AC) of a territory. The article analyzes the existing approaches to determining and assessing the AC of a territory. We justify the advantages of using the energy approach. The authors' method consists in using the maximum permissible energy load (MPEL) for quantitative assessment of the AC of a territory. MPEL is a value that the ecological and economic system can withstand for a long time without changing its properties. We determine MPEL on the basis of data on the ability of various categories of land to absorb greenhouse gases (GHG), as well as the specific GHG emissions per ton of conventional fuel. Further, we compare the calculated value of MPEL in fuel equivalents with the actual consumption of fuel resources for the needs of the national economy. These values ratio can serve as a standard for measuring and balancing the environmental and economic system. The authors have validated the described method on the example of the Sverdlovsk region, which is characterized by a high level of man's impact. Calculations show that the actual consumption of fossil fuels in the region exceeds MPEL. That indicates an imbalance in the ecological and economic system and may lead to further deterioration of the environmental quality in the region. The proposed methodological approach and calculations can be used when developing strategic planning documents for a territory, including its energy strategy. Рассмотрены существующие подходы к определению и оценке ассимиляционного потенциала территории. Предложен методический подход, особенностью, которого является применение для количественной оценки ассимиляционного потенциала территории предельно допустимой энергетической нагрузки, которую может на протяжении длительного времени переносить эколого-экономическая система без нарушения своих основных свойств. Апробация методики расчета предельно-допустимой энергетической нагрузки проведена на примере Свердловской области, территория которой подвергается высокому антропогенному воздействию.

Kirov; M.P. Galatsan;The analysis of the world electric-energy balance revealed the advantage of steam turbine plants. An increase in their efficiency through the improvement of the initial parameters runs into difficulties associated with creation of new materials. The efficiency increase that results from the final pressure reduction requires an improvement of the circulating water supply system. The aim of this work is to determine the effect of the water-cooling tower on the electric power station profitability. This goal was reached by the creation of a mathematical model of the water-cooling tower and turbine plant with a condenser connected to each other. The calculations were made for two types of cooling tower fill packing: asbestos cement sheets and mesh elements made of polyethylene. Further, according to it, the vapor condensation temperature was determined. The latter affects the vapor discharge in the condenser, the capacity of the turbine plant and the temperature of the cooling water at the condenser output, i.e. at the cooling tower input. The novelty of this work consisted of consideration of the interaction between the cooling tower and turbine plant. Significance of the obtained results lies in the fact that, taking into account the reciprocal influence of the turbine plant and cooling tower, the efficiency of the fill packing replacement turns out to be major comparatively to the case without considering this influence. The replacement of the fill packings the half-a-year average temperature of condensation will become lower by 2.34 °С, electricity production increases by 41.72 GWh.

For further information contact us at helpdesk@openaire.eudescription Publicationkeyboard_double_arrow_right Article 2023Publisher:MIRBIS Institute В материалах статьи представлены результаты исследования динамики, масштабов и структуры потребления энергоресурсов и электрической энергии в различных мировых континентах и крупнейших странах мира, с выявлением основных тенденций, а также оценкой факторов, влияющих на возникновение таких изменений. В материалах показано, что показатели различия объемов годового потребления энергоресурсов и электроэнергии странами мира могут достигать десяток или сотен крат, что связано с различием масштабов экономик и уровнем экономического развития. Построенная диаграмма показателей объемов потребления энергоресурсов и ВВП по ППС в странах мира позволяет констатировать факт прямой зависимости между данными показателями. Показано, что чем больше экономика производит валового внутреннего продукта, тем больше она обрабатывает сырья и оказывает услуг, что, следовательно, сопровождается потреблением энергетических ресурсов и электрической энергии. Различие характеристик общего потребления энергетических ресурсов и электрической энергии в странах мира определяет необходимость реализации дифференцированного подхода к управлению топливно-энергетическими комплексами и процессами повышения энергетической эффективности. В рамках статистических данных различных стран мира показано, что характеристики потребления первичных энергетических ресурсов, используемых на выработку электроэнергии значительно отличаются между собой не только в рамках какого-то статического периода, но и в динамике отражающей изменение структуры общего спроса в странах. В процессе развития энергетической политики различных стран мира необходимо учитывать ряд важнейших факторов, прежде всего связанных с масштабами потребления энергоресурсов, структурой ТЭР, динамикой изменения потребления энергоресурсов в различных периодах, а также с учетом факторов, влияющих на такую динамику. Качество формирования энергетической политики, нормативно-правовых актов регулирующих потребление энергоресурсов имеет прямое влияние на уровень экономического развития каждой страны мира и отдельного территориального образования. The article presents the results of a study of the dynamics, scale and structure of energy and electricity consumption in various continents and major countries of the world, identifying the main trends, as well as assessing the factors influencing the occurrence of such changes. The materials show that the indicators of the difference in the volume of annual consumption of energy resources and electricity by countries of the world can reach tens or hundreds of times, which is due to the difference in the scale of economies and the level of economic development. The constructed diagram of indicators of energy consumption and GDP by PPP in the countries of the world allows us to state a direct relationship between these indicators. It is shown that the more the economy produces gross domestic product, the more it processes raw materials and provides services, which, therefore, is accompanied by the consumption of energy resources and electrical energy. The difference in the characteristics of the total consumption of energy resources and electric energy in the countries of the world determines the need to implement a differentiated approach to the management of fuel and energy complexes and energy efficiency improvement processes. Within the framework of statistical data from various countries of the world, it is shown that the characteristics of consumption of primary energy resources used for electricity generation differ significantly not only within a static period, but also in dynamics reflecting changes in the structure of total demand in countries. In the process of developing energy policy in various countries of the world, it is necessary to take into account a number of important factors, primarily related to the scale of energy consumption, the structure of the fuel and energy complex, the dynamics of changes in energy consumption in different periods, as well as taking into account factors affecting such dynamics. The quality of the formation of energy policy, regulatory legal acts regulating the consumption of energy resources has a direct impact on the level of economic development of each country in the world and a separate territorial entity.

Считается, что основной причиной глобального потепления является технический прогресс. Техносферная деятельность человека приводит к росту содержания в атмосфере парниковых газов за счет все большего сжигания топлива, что является фактором, повышающим температуру. Климатические аномалии провоцируют социальные катаклизмы. Важнейшей задачей на современном этапе является снижение глобальных рисков и повышение безопасности людей. Эффективным инструментом повышения устойчивости среды обитания является строительства «зеленых» зданий. В данной статье выполнен аналитический обзор современной направленности работ в области «зеленого» строительства в России и в зарубежных странах. Рассмотрены основные принципы «зеленого» строительства, концептуальные основы зданий с низким энергопотреблением. Показано, что «зеленые» крыши и «зеленые» фасады являются важными элементами формирования экологически устойчивой архитектуры и энергосберегающего строительства. Рассмотрены проблемы повышения энергоэффективности при термореновации фасадов зданий. Рассмотрены принципы рейтинговой оценки в «зеленом» строительстве. Полученные результаты имеют важное практическое значение. Систематизация и обобщение данных по «зеленому» строительству позволяют наметить дальнейшие пути повышения энергоэффективности и экологической безопасности зданий и сооружений при решении актуальной проблемы повышения устойчивости среды обитания в градостроительстве и архитектуре. It is considered that technical progress is a basic reason of global warming. Activities of the person lead to growth of content in the atmosphere of greenhouse gases due to the increasing combustion of fuel that is the factor of increasing temperature. Climatic anomalies provoke social cataclysms. The major task at the present stage is decrease in global risks and increase in safety of people. The effective instrument of increase in sustainability is constructions of green buildings. In this article the analytical review of a modern direction of the green construction problem in Russia and in foreign countries is executed. The basic principles of a green construction, conceptual bases of buildings with low energy consumption are considered. It is specified that green roofs and green facades are important elements of ecologically steady architecture and energy-saving construction. Problems of increase in energy efficiency in case of thermorenovation of facades are considered. The principles of rating in a green construction are indicated. The received results have important practical value. Systematization and generalization of data on a green construction allow to plan further ways of increase in energy efficiency and ecological safety of buildings and structures in case of the solution of an urgent problem of increase in sustainability in town planning and architecture.

A variant of a sailing power plant is known that converts the energy of a wind flow into the energy of a water flow, which makes it possible to reduce the size of the energy converter, but its efficiency decreases, since part of the energy of the wind flow is spent on moving the sail installation, and there are also difficulties in transferring the generated energy to an external consumer . A variant of a ground-based sailing power plant is proposed, in which these problems are removed. The conducted experimental studies of models of ground-based sailing power plants have shown the operability of the elements included in the experimental installation, structural elements have been found that can be used in the implementation of a ground-based sailing installation. In order to determine the power that land-based sailing installations can develop, studies were carried out on the developed experimental installation to determine the magnitude of the forces on which the speed of movement of the sailing installation models depends. The results of these studies are presented in this article.
