With the development of China's economy, the transformation of the terminal energy consumption structure has been put on the agenda. For this reason, the government proposes the Electric Power Alternative plan to promote electricity consumption and ban the consumption of traditional fossil energy. In view of the existing power instead of the terminal energy evaluation method of low efficiency, low...
This paper presents the study of energy efficiency in industry based upon information measurements, audits and technological processes. The economic operators analysed in this study are companies with primary activity in metalworking, food and bakery industry. The products of these companies belong to categories like: bread and specialities of bread, industrial scales, bearings and meat processing.
Natural gas is an energy resource that is widely used as energy and raw material in many industrial processes. It is contaminated some impurities such as CO2, H2S and water, hence, removal of the contaminant processes are required. One of the natural gas processing is Acid Gas Sweetening. The purpose of this process is to eliminate H2S and CO2 compound from natural gas. H2S tend to corrosive and CO...
Over the spring and summer 2015 semesters, two undergraduate students completed a full energy audit of two local municipalities in order to provide recommendations for usage reduction. This audit was done as part of a community partnership initiative with Emerald Cities Collaborative, a community development collective focused on promoting sustainable communities through environmental energy education...
In recent years, there have been significant developments of applications related to “Energy Hub” and “Smart Grid” concepts. Synergy effect of the coupling between electricity and natural gas infrastructures, and approaching energy systems to the smart grid environment leads us to introduce a new solution. This solution is entitled “Smart Energy Hub” (S. E. Hub). Simply stated, the S. E. Hub models...
Energy audit is a primary step towards a more rational use of primary energy sources in the energy-intensive process such as the production of packaging paper. By the adoption of the Law on efficient use of energy in 2013, energy audits have become mandatory for all industrial companies in Serbia. This paper presents the methodology and results of the one-day energy audit which was conducted in the...
This article uses Grey Markov forecasting method in Chongqing during the “twelfth five-year” natural gas demand forecasting. Put forward the improved method based on GM (1, 1) model, the fitting precision and prediction precision are greatly improved, good results were obtained. Predicted results show that with the rapid development of Chongqing economy and requirement of low-carbon economy development,...
Basd on the panel data of China's 36 industrial sectors in 2000-2009, this paper analyzes the energy relationship of different sectors by grey relational theory. Results show that China's industry is strongly dependent on fossil fuels, and China needs optimize its industrial energy consumption structure. To do that, this paper finds out the industrial sub-sectors which should reduce fossil energy...
Optimization of energy use is a vital concept in providing solutions to many of the energy challenges in our world today. Large chemical, mechanical, pneumatic, hydraulic, and electrical systems require energy efficiency as one of the important aspects of operating systems. At the micro-scale, the built environment experiences progressive changes in energy consumption. There is steady increase in...
According to the recent research significant amount of building energy consumption can be saved through optimized operation and management and it is not necessary to change the building structure and the hardware configuration of the energy supply system. Therefore, there is a huge potential for building energy savings through efficient operation. In this paper a smart building (microgrid) is assumed...
The potential of distributive technologies in meeting future energy demand and reducing greenhouse gas emissions are enormous. However, improvements in efficiency and a reduction in capital cost are essential for them to be competitive against conventional energy sources. Natural gas microturbines are an example of distributive technologies that are growing in popularity among commercial and industrial...
The rapid urbanization is an important driving force of rapid economic development and energy consumption growth in China. The aim of this paper is to study the mode of energy consumption and existent problem in metropoLis of China during the fast economic growth course. As an international metropoLis and the economic center of China, Shanghai is taken as a case to be studied in this paper. Characteristics...
Abstract??FEnergy consumption structure is an important factor affecting the level of energy efficiency. Quantitative analysis is a necessity to ensure the rationality of China's energy consumption structure. Based on information entropy, this paper evaluates the evolution of China's energy consumption structure and obtaines the slow trend of China's improving energy consumption. On the basis, this...
The rapid increase in economy and improvement in living standard of households in China require more increased input of energy, while increased energy consumption results in severe environment pollution, which in turn affects environmental quality and economic development. Using grey relevancy analysis and these data about consumption of energy and environment quality from Beijing, we studied the...
The present study involved two key procedures: (1) Input-output table including energy consumption is built and some parameters, such as coefficient of industrial correlation, energy consumption per unit of output value and elasticity ratio of energy consumption, are calculated. (2)Based on characteristics of industrial correlation and energy consumption four industry classes (I, II, III, IV) are...
Along with the continuous progress of modernization, China's economy maintains a comparatively high growth rate, above 8% from 2000 to 2010. Generally speaking, one country or region's GDP growth rate is roughly proportional to growth rate of energy consumption. As the economy grows continuously, the sustaining increase of energy consumption causes serious greenhouse effect by CO2 emissions. This...
By the specific analysis of electricity consumption and water supply in nationwide universities, this paper clearly indicates the level of energy consumption recently in relevant area. Then, according to the different climatic zones, the universities are divided into four groups, such as severe cold, cold, hot summer and cold winter, hot summer and warm winter areas, so that we can analyze and focus...
Natural gas consumption growth rate in Iran over the past decade has been usually over than the world wide consumption. As temperature variation has an inevitable effect on raw material consumption which supplies thermal and cooling energies in different areas of the society so in this research we are going to investigate the temperature effects on different sectors of natural gas consumption such...
With China's rapid economic development and the world's total primary Energy declining, Energy bottleneck effect on China's economy has become increasing evident. China's economic growth pattern is in the transitional period from extensiveness to intensiveness, the improvement of the energy structure also becomes more urgent. In this paper, the authors put forward some measures to adjust China's energy...
As a result of the depletion of easily exploitable and therefore cheap coal mines, new power plants have been built or are in construction for burning low value, high moisture content lignite in several countries.
