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 1.1 trillion tonnes of proven coal reserves worldwide. Ten countries are responsible for 90 of the total global coal production.
Production and costs. Germanys hard coal mines produced 41.3Mt in 1998, 39.2Mt in 1999, 33.3Mt in 2000 and 27.1Mt in 2001. By 2006, their combined output had fallen to 20.7Mt. Production costs are three or four times the world average, Ruhr coal costing an average of around 120t.
