Coal Facts

Coal is the world's largest source of energy for the production of electricity. Coal is converted to electricity by being burned in a furnace with a boiler. The boiler water is heated until it becomes steam, with the steam then spinning turbines and generators to create the electricity. Nearly 70% of China's electricity comes from coal.
