Extracted from text ... More than 77% of our total energy needsat a global level are currently satisfied bycoal, and we rely on burning carbon-releasing fuel (coal, oil, liquefied petroleum, natural gasesor wood) for a total of 97% of our energy needs. In South Africa, Eskom generates about 71% of itselectricity from coal-fired power stations. Not only are these conventional sources of energy nonrenewableand in dwindling quantities, but they threaten massive environmental disruptionthrough global warming. The continued exploitation of these resources at current consumptionlevels will also lead to its complete depletion and ultimately to massive industrial and socialdislocations.
