Coal in China - Wikipedia

China is the largest producer and consumer of coal in the world and is the largest user of coal-derived electricity. The share of coal in the energy mix declined during the 2010s, falling from 80% in 2010 to 60% in 2017. Domestic coal production also decreased with a year on year decline of 9% in 2016. However, imports of coal increased to compensate for the cuts to domestic coal production.
