Concept
Peak coal
Résumé
Peak coal is the peak consumption or production of coal by a human community. Global coal consumption peaked in 2013, and had dropped slightly by the end of the 2010s.
The peak of coal's share in the global energy mix was in 2008, when coal accounted for 30% of global energy production.
The decline in coal use is largely driven by consumption declines in the United States and Europe, as well as developed economies in Asia. In 2019, production increases in countries such as China, Indonesia, India, Russia and Australia compensated for the falls in the United States and Europe. However, coal's structural decline continued in the 2020s.
Peak coal can be driven by peak demand or peak supply. Historically, it was widely believed that the supply-side would eventually drive peak coal due to the depletion of coal reserves. However, since the increasing global efforts to limit climate change, peak coal has been driven by demand, which has stayed below the 2013 peak consumption. This is due in large part to the rapid expansion of natural gas and renewable energy. Many countries have pledged to phase-out coal, despite estimates that project coal reserves to have the capacity to last for centuries at current consumption levels. In some countries coal consumption may still increase in the early 2020s.
Although reserves of coal remain abundant, consumption of coal has declined in many countries. In 2016, Scotland closed its last coal-fired power plant, accommodated by an increase in nuclear power generation (to 42.8% of 2016 output). Scottish renewable energy comprised 42.9% of 2016 output. The term "peak coal" is now used primarily to refer to a peak and subsequent decline in global and national coal consumption. In 2016 experts estimated that China, the world's largest coal consumer, reached peak coal in 2013, and that the world may have passed peak coal. However, in 2017, for the first time in four years, demand for coal rose.
As of 2015, China accounted for 50.0 percent of world coal consumption. Chinese coal consumption fell in 2014 and 2015.
