Economic Impact of Coal Mining in South Africa

Coal is South Africa’s third largest source of foreign exchange; platinum being the largest and gold second. Around 15% of the country’s GDP (2000 estimate) is spent on energy and 77% of that is derived from coal. In 2004, the coal and lignite mining industry generated a gross income of R39 billion and directly employed 50,000 people.
