coal future use, page-11

" Measured in terms of produced tons per miner, US productivity steadily increased until 2000, but has declined since, which also implies that ‘easy coal’ is running short.

The USA had passed peak production of anthracite (by far the rarest form) by 1950 and peaked in bituminous coal in 1990, but sub-bituminous coal more than made up for this decline in terms of tonnage. However, due to the lower energy content of softer coals, the total energy content of annual US coal production peaked in 1998.

The Energy Watch Group report gives projected production profiles showing that China is likely to experience peak coal production in the next 10-15 years, followed by a steep decline.

According to the Energy Watch Group, global coal production can increase for 10-15 years (mainly driven by China), but then production of anthracite and bituminous coal will peak around 2020 at a production rate around 30% higher than at present. Lignite production is predicted to peak somewhere between 2050 and 2060. However, as the quality of coal produced will be declining continuously the world coal energy peak is projected to come around 2025. It is also important to note that ‘peak coal exports’ should come even earlier, as lower-energy-density coals are not worth transporting long distances.
