Coal is the largest source of energy for the generation of electricity worldwide, as well as one of the largest worldwide anthropogenic sources of carbon dioxide emissions.
Gross carbon dioxide emissions from coal usage are slightly more than those from petroleum and about double the amount from natural gas. Coal is extracted from the ground by mining, either underground or in open pits. The major coal exporting countries include Australia, Indonesia and South Africa. We are importing Coking Coal for Cookeries and Steam Coal for Power and Cement Plants in India.
