The restructuring of the international coal industry
The international coal industry is now becoming a global industry emerging from a history of production for national purposes and isolated regional markets. The participants in the market are also changing; the oil companies have come and gone and production is now in the hands of specialist mining companies. This has implications for the way the industry is organised. Deregulation in the ...

Scrutinising the influence of the performance of Malaysia agricultural sector on energy use
Most sectors rely on energy as input to produce output. Though the use of energy by the agriculture sector is not as high as in other sectors, it is still necessary to study the links between the two. This is vital as there are only few studies that illustrate the bonds between them in Malaysia. This study resorts to input–output analysis to examine the link between the two sectors and ...

A long year in the life of the US coal industry
With concerns about climate change mounting, the era of coal-fired electricity generation in the United States may be coming to a close. In early 2007, a US Department of Energy report listed 151 coal-fired power plants in the planning stages in the United States. But during 2007, 59 proposed plants were either refused licenses by state governments or quietly abandoned. In addition, close to 50 ...

Coal and its future are fueling conflicts around the globe
"Coal Wars: The Future of Energy and the Fate of the Planet" (Palgrave Macmillan), by Richard Martin Fierce conflicts over coal are taking place around the globe, but author Richard Martin says the decline and ultimate demise of the fuel that powered the Industrial Revolution is inevitable and cannot be reversed. What he cannot predict, he says, is whether the transition to energy sources that ...

Comparison of employment potential of the coal and wind power industries
Australia, one of the world's largest producers of coal, is used as a case study to compare the employment potential in the coal and wind power electricity generation industries. It is revealed that, as a result of automation, employment in the coal mining industry fell by 45% between 1987 and 2002. Moreover, as a result of the restructuring of the electricity industry as a whole, employment in ...

King Coal’s Climate Challenge
Coal is emerging as a major topic of conversation at the United Nations climate-change negotiations currently taking place in Warsaw – and rightly so. Indeed, it is a discussion that the world needs to have. The latest findings of the Intergovernmental Panel on Climate Change conclude that we are quickly using up our carbon “budget” – the amount of carbon that we can ...
