ABSTRACT
Coal is one of the many vital commodities that contributes on a large scale to energy supply and, unfortunately, to environmental pollution, including acid rain, the greenhouse effect, and allegedly global warming (global climate change) (Bell, 2011). Whatever the effects, the risks attached to the coal fuel cycle could be minimized by the introduction of new clean coal technologies (Chapter 22), remembering that there is no single substitute for coal fuel in the generation of energy.
