Currently, over a quarter of the world’s primary energy supply comes from coal. Since the rich world has already created its coal infrastructure, the increased use of coal in China and India is now under scrutiny. In 1980, rich countries used over 65 per cent of the world’s coal; in 2000 their share was roughly 50 per cent. By 2005, this figure fell to 38 per cent as consumption in China and India grew.
