Coal production continues to grow globally due to the demand for low cost energy and iron and steel, as well as cement. Coal, based on the current extraction rates, will last about 115 years longer than conventional oil and gas reserves, with an estimated trillion tonnes of proven coal reserves worldwide. Ten countries are responsible for 90% of the total global coal production.

Coal is the most abundant fossil fuel on Earth. Its predominant use has always been for producing heat energy. It was the basic energy source that fueled the Industrial Revolution of the 18th and 19th centuries, and the industrial growth of that era in turn supported the largescale exploitation of coal deposits. Since the mid20th century, coal has yielded its place to petroleum and natural ...

The energy in the fossil fuels started by bonds formed from sunlight. Coal comes from ferns, plants and trees. Woody plants result in coal, slimy plants like algae produce oil, and both can result in natural gas. Burning these fossil fuels is reversing the process that stored all this carbon in Earth's crust for hundreds of millions of years.
