Factoring energy security into Australian foreign and trade policy: Has luck run out?
When energy prices rose dramatically in the 1970s, the impact on Australia was cushioned by two developments: the timely discovery of domestic oil in Bass Strait; and of the Japanese conversion to thermal coal. With falling oil imports and expanding coal exports, Australia emerged as a net energy exporter. But both these forms of good luck are now running out ? and at a time when free market ...

Assessment of severe accident risks in the Chinese coal chain
Severe accident risks in China's coal chain were investigated in detail based on extensive statistics using Chinese sources that were not open until recently. Every year about 6000 fatalities occur in Chinese coal mines; about one third due to severe (≥ five fatalities) accidents. The Chinese severe accident fatality rate for the coal chain is 6.17 per GWeyr, which is about 10 times higher than ...

Energy recovery from waste by use of fluidised-bed technology
Revolving type fluidised-bed technology, developed by Ebara Corp., is installed in more than 100 facilities worldwide. The technology is applied for waste, coal and in situations where a conventional fluidized bed is difficult to use. Waste and/or coal can be treated and valuable energy can be recovered from a non-renewable source. This paper describes the application of the revolving fluidised ...

Planning the future of Botswana's coal
Botswana has vast proven deposits of steam coal, which, for a long time, the government has wanted to develop but without much success. The main objectives of this study are: to forecast possible coal exports from Botswana and the land routes for these exports; to determine the competitiveness of Botswana's coal in world steam coal trade; to make recommendations on the appropriate policy for the ...

The structural break and elasticity of coal demand in China: empirical findings from 1980-2006
Coal is the principal primary energy source in China. Research on coal demand is vital for informing China's economic development. In this paper, the theoretical structural break of coal demand was tested using annual time series data from 1980 to 2006. Results indicate that coal demand underwent an intercept structural break during the period 1997-2000 (from −0.536 breaking to −0.702). Then ...

Environmental impacts of integrating wind energy systems and supplemental energy generation and storage systems
Wind energy systems offer a promising alternative energy source due to the environmental, economic, and social benefits and, as a result, have garnered support for development and implementation. One of the major drawbacks of wind energy, however, is its variability due to the stochastic nature of wind, thus, supplemental energy generation or storage technologies are required. In this study, a ...

Prospects for nuclear energy in South Asia in the 21st century
The South Asian region is characterised by low per capita energy consumption. There are large differences in the region with regard to energy resource endowments. In the entire region one notices an excessive use of non-commercial energy. The region has significant hydro-potential, which needs to be fully exploited. There are possibilities for trade in energy in the region. India is the largest ...

Coal sorption characteristics and coal surface tension
Underground coal mining in the Bulli Seam of Sydney Basin, Australia encounters the problems of coal and gas outburst as the coal contains high concentration of CO 2 , where certain parts of the seam have been found to be especially hard-to-drain. In order to better understand these problems, the influence of temperature and moisture on sorption capacity of bituminous coal was investigated at ...

The influence of climate change considerations on energy policy: the case of Russia
To those working on climate change, it is obvious that energy policy should be influenced by climate change considerations. The question that this paper seeks to answer is, to what extent do they influence policy and what contribution can a careful analysis of the costs and benefits of climate change options have on the formulation of that policy? We seek to understand this by looking in some ...

Targeted opportunities to address the climate–trade dilemma in China
Abstract International trade has become the fastest growing driver of global carbon emissions, with large quantities of emissions embodied in exports from emerging economies. International trade with emerging economies poses a dilemma for climate and trade policy: to the extent emerging markets have comparative advantages in manufacturing, such trade is economically efficient and desirable. ...

A global clean fossil scenario
In this article, a so-called Clean Fossil Scenario (CFS) [1], valid for the year 2050, based on a bottom-up demand analysis, is described. It is proposed to mitigate the rise of atmospheric CO2 concentrations by disposing of the CO2 in deep sea and in other reservoirs to limit its liberation to the air. The scenario is clean, because emissions to the environment are reduced drastically compared ...

Prediction of demand trends of coking coal in China based on grey linear regression composition model
The scarce of coking coal resources in China results in its short supply. By establishing a grey linear regression composition model, this paper has greatly improved the inadequacy of grey system prediction model and regression analysis method in trend prediction and finished the prediction of demand trends of coking coal in China with this model. As result of the prediction, it is estimated that ...

Partition of regional types on rural household energy consumption of province-level regions in China
In order to classify regional types of rural household energy consumption (RHEC) in China, this paper selects the following as the characteristic indices for regional classification: per-capita available heat consumption for cooking and heating per day (PCAHC), annual per-capita electricity consumption for livelihood (PCEC), ratio of commercial energy in PCAHC (RCE), per-capita energy consumption ...

'Strong enterprise, weak government': energy policy making in China
China lacks a cohesive energy plan, but in light of its rapidly increasing energy consumption and low energy efficiency, it desperately needs one. Many different actors influence energy policy, with varying degrees of impact, as the methods of policy formulation are extremely ambiguous and fluid. Chinese energy policy has been characterised by bureaucratic overlap and competition, while free ...

POLITICO takes a hard look at the future of energy
In 2007, the investigative news site POLITICO launched and quickly became a go-to source for news about policy decisions coming from the nation’s capital. Now, the folks behind POLITICO are turning their lens to the U.S. energy sector with Future of Power, the inaugural special report of the Agenda, an online magazine launched this week that will be looking to “connect the dots ...

Rural energy in Jiangsu Province of China: survey of renewable energy source and energy consumption
In recent years, the structure and level of energy consumption in the rural areas of Jiangsu Province, a large province of China in terms of economic development and population, have been changing rapidly. Total energy consumption was about 61 Mtce in 1997, of which 63.0%, 9.7% and 27.3% were used respectively for rural industry, cooking and farming, and of which 44.0$, 26.2%, 7.5%, and 21.8% ...

Forecasting of commercial energy consumption in India using Artificial Neural Network
The forecasting of energy consumption is essential for any country to study the future energy demand and to introduce the necessary government policies. This paper presents the formulation of forecasting models based on the Artificial Neural Network (ANN) for the consumption of conventional energy sources. In India, the total energy consumption for coal, oil, electricity and natural gas would be ...
