The rapid growth of the auto industry is a major challenge to reduce CO2 emissions in China. Promoting energy-saving" & new energy vehicles should be effective to tackle the issue. This paper aims to evaluate impacts of such promotion on CO2 emission reduction. Scenario analysis method and the Gompertz model are adopted to simulate future auto market scale and structure. Possible emission...
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...
This paper researches on the energy saving economy of the oil pipeline in gaosheng when the second heat station stops heating. First, every month total heat transfer coefficient is calculated according to the historical pipeline operation data and the temperature of the soil at the buried depth with the method of least squares. Second, basing on every month total heat transfer coefficient, the finite-element...
Energy is the most important material for economic development, social progress and human survival. With global warming and increasing environmental pollution, energy conservation, low-carbon economy and renewable energy are paid more attention around the world. In this paper, energy production and energy consumption in Heilongjiang province are analyzed from different standpoints, and it is concluded...
Renewable energy is one of the vital sources to meet partially the global energy demand of developed as well as developing countries. Biogas plant can be one of the major sources of renewable energy in Malaysia as huge amount of palm oil waste is available. Biogas plant can be of different types of which fixed dome and floating cover are in use in many countries for many years. The bag design is becoming...
Sustainability is becoming an issue of public concern, particularly for large scale development projects. In this work, a multi-criteria approach, called the sustainability assessment method (SAM), is used to asses and rank the sustainability of various types of power plants firing on different types of fuel. It traces the impacts of using coal, oil, and natural gas for power generation over its full...
This paper applies the grey relational analysis to measure the grey relational degree between the energy consumption and the economic system from 2000 to 2007. The results show that the fixed asset investment of the economic system is the major factor which results in a rapid growth of the energy consumption; the grey relational degree between coal consumption and economic system is greater than the...
This paper applies grey incidence analysis to study the relationship between energy consumption structure and GDP growth during the ??the ninth five-year plan?? and ??the tenth five-year plan?? in China, and uses GM(1,1) model to predict the total energy consumption in the future. The result indicates that the order is coal, crude oil, natural gas, hydro-power, nuclear power and wind power in turn...
With the development of China economy, energy consumption increases rapidly, which results in a series of social problems. In these problems, environmental issues are still prominent. The enormous energy consumption deteriorates the environmental quality, and hinders the economy growth. In this paper, Grey relational analysis of `grey theory' is adopted in the study of the relationship between China's...
In recent years, the world energy market has changed significantly. Especially, the demand of the oil has been increasing day by day. The natural gas was only the accessory of the crude since its discovery. Some expertise predicts that natural gas will be the first energy in the future. As one of the most potential future energy, natural gas will play an increasingly important role during the country's...
Energy is important to human existence, economic development and society progress, which is also related to safety of a country and sustainable growth of economy. China is a rapidly developing country, where the decisions about energy alternatives are critical. This paper discusses coal, petroleum, natural gas, nuclear energy and renewable energy resources as energy alternatives for China. The paper...
Does co-integration help long-term forecasts? We use simulation, real data sets, and multi-step-ahead post-sample forecasts to study this question. Imposing unit-root constraints suggested by co-integration tests produces better forecasts for some cases, but fares poorly for others.The composition of total energy consumption in China is very important, which can be analyzed by means of the co-integration...
This paper sets up a dynamic model of energy consumption structure in China and selects two different groups of data to simulate and forecast the trend of the energy consumption structure. The forecast result is that the consumption rate of coal will decrease, while the rates of electricity, natural gas and petroleum will increase. Because the two groups of data are from different periods, there is...
Nowadays, energy safety is closely related with state safety. Under the global energy market system, if a country only considers its own safety, it always goes to the opposite direction, especially facing energy crisis, it must depend on the collective strength and the wisdom. In the paper, first we defined the concept of energy safety, analyzed the current situation of energy safety of Northeast...
Energy is the bedrock of our daily lives and industry. Now is the time that industry, government and academia must join together and examine highly independent, fully environmentally considerate and rational energy systems. In this presentation, recent Japanese policy will be introduced focusing on new national energy strategy. Looking at future technology trends, it is probable that, in the case...
