The energy price influence system is one of the key mechanisms in the study of energy consumption. China’s household energy consumption has obvious regional differences, and rising income levels and urbanisation have changed the willingness and ability of households to make energy consumption choices. Based on the linear price effect of household energy consumption, this paper explores the scenario characteristics of energy prices affecting energy consumption, taking electricity and natural gas consumption as examples. Based on household energy consumption statistics from 2005 to 2018 in 36 major cities across China, the accuracy and change trends of household energy consumption forecasts are investigated through the decision tree-support vector machine (DT-SVR) non-linear forecasting technique. The study shows that the non-linear forecasting technique accurately portrays the predicted trends of changes in total urban household electricity and natural gas consumption. Within the less developed regions of economic development, income levels are still the main constraint on changes in urban household energy consumption, and the stimulating effect of income levels on household energy consumption has not been seen in the process of economic development in these less developed regions. Urbanisation as an important factor in examining household energy consumption, different development patterns and development processes will gradually be reflected in scenario aspects such as the choice of urban household energy consumption and changes in total consumption.

To solve the contradiction between achieving long-term economic growth and reducing the consumption of certain types of resources, the concept of sustainable resource saving economic development must be put into practice. The purpose of this research is to establish criteria, develop indicators, and identify factors of the sustainable energy-saving economic development, as well as to test the developed theoretical provisions using the example of natural gas consumption by different countries. To achieve this goal, various methods were used, including economic and mathematical modeling, time series analysis, factor analysis, regression analysis, and so on. The criteria were formalized, according to which a certain type of economic development can be attributed to energy saving both at the level of the state economy as a whole and at the level of individual industries and enterprises. It was established that the formalized criteria of the sustainable energy-saving economic development have the form of chains of inequalities, and their application makes it possible to identify the general conditions for ensuring this type of development. The main properties of energy-saving economic development were identified. They include the pace of this development, its potential, balance, permanence, and other characteristics. Indicators that can be used to quantify these characteristics were developed. The factors influencing the scale and time characteristics of sustainable energy-saving economic development at the level of the state economy and that of industries and individual enterprises, were systematized. The dynamics of natural gas consumption in different countries was analyzed. The reasons for the lack of energy-saving natural gas economic development in some countries were identified. A quantitative assessment of the properties of this type of economic development by country was conducted. The influence of some factors on the parameters of the sustainable energy-saving natural gas economic development of countries was analyzed. The existence of a negative effect of the rebound in the consumption of natural gas was established at certain intervals in some countries. The obtained results provide an opportunity to increase the degree of understanding of the complex patterns that underlie the sustainable energy-saving economic development of states, industries, and enterprises. These results can also be used in the development of government programs to stimulate energy conservation.

The existing modern conceptual approaches to the formation of an assessment of the natural gas consumption strategy in the steel industry do not allow assessing comprehensively all the processes that occur in the enterprise affecting the efficiency of natural gas consumption. Due to the fact that natural gas acts an important role as a universal energy resource, both in the economy and in international politics, the modern strategy for assessing the consumption of natural gas in the steel industry is becoming a key factor in increasing competitiveness and guaranteeing sustainable economic growth of the country's steel industry. The article proposes a conceptual approach to the development of the model in order to assess the strategy of natural gas consumption at iron and steel enterprises, which allows timely management decisions to be taken to increase the organization of efficient energy consumption at the enterprise. Based on the proposed conceptual approach to assessing the strategy of natural gas consumption at the iron and steel industry, it can be stated that this assessment is interconnected with the assessment of the integral criterion for the implementation of the goals of organizing effective energy management.

New three- and four-cycle experimental cementation regimes for a layer thickness of up to 4.0 mm in an atmosphere of natural gas with air additives have been developed. Rational schemes for adding air to the atmosphere of methane for carburizing in shaft furnaces at different thicknesses of the hardened layer have been determined. Industrial testing of new modes has shown the possibility of reducing the total duration of the cementation process by 25%; significant reduction in energy consumption for heating furnaces and reduction of natural gas consumption for one carburizing mode by 35%.

Underground storage of natural gas is an inevitable necessity because of increasing growth of household energy consumption, the high share of natural gas in the energy basket, high costs of development of production resources, and refining. Considering the growth of demand and variation of natural gas consumption as a massive and inexpensive energy carrier, also unbalanced supply and demand for natural gas in cold seasons, there is a need for natural gas storage for preventing lack of gas during peak gas consumption. In this way, extra gas is injected into the underground reservoir during storage in summer and taken from that reservoir in the cold seasons. The creation of underground reservoirs for storing natural gas is scheduled to be implemented by the gas storage company and the vulnerability of the transmission and distribution system will be prevented by storing surplus gas in summer for reprocing in winter.

Assessment of gendered energy transition at an urban scale has emerged as a challenging issue for researchers, policy makers and practitioners. With municipalities becoming players in the energy markets, their involvement raises policy issues that need to be better assessed in supporting gendered energy transition. This paper, therefore, contributes to gendered energy transition assessments at urban household level from a policy maker perspective. We developed a system dynamics model to assess the effects of urban energy policy interventions on household energy consumption and gendered measures using Drakenstein Municipality as a case study. The study used secondary data from various sources for the model parameters. We tested three hypothetical policy scenarios: the business-as-usual, the energy subsidy policy and the energy efficiency policy. The results show that understanding the changes in urban household energy consumption and gendered measures due to energy transition interventions is essential for urban policy planning. The energy subsidy policy scenario was observed to increase total energy consumption but also resulted in socio-environmental impacts that might increase inequality and impair human health. Urban household energy transition interventions need to consider a systems approach to develop decision support tools that capture the cross-sector impacts and inform the development of interventions that promote gendered household energy transition.

The Relationship

The Northeast Asia, as one of the most rapidly development regions, has a large amount of energy consumption. Therefore, it is very significant to study the relationship between natural gas consumption and economic growth in the Northeast Asia. This paper builds Panel Data Model to study the relationship between natural gas consumption and economic growth in China, Japan, and Korea from 1991 to 2015, on the basis of analyzing the impact mechanism that natural gas has on economic growth. This paper finds that the Japan’s elasticity coefficient of natural gas consumption is the highest, whereas Korea’s is the lowest, and China’s is in the middle of these two countries, because of countries’ different development level and energy consumption mode. Moreover, the results of Granger causality relationship test show that there is only one-way Granger causality relationship between natural gas consumption and economic growth of China, but no causal relationship is found for Japan and Korea.
