The average price of coal fell five cents per million Btu from 2018 to 2019. The industrial sector price decreased 16 cents, and the electric power sector price fell three cents. The residential sector, the commercial sector, and the transportation sector had no reported prices.
The transportation sector price paralleled the commercial and industrial sectors' prices from 1970 to 1977 with the last reported price for the transportation sector in 1977. If coal was consumed in the transportation sector after 1977, the amount rounded to zero, so a price was not reported.
The commercial and industrial prices paralleled each other from 1970 to 1998 and again from 2001 to 2007.
If coal was consumed in the commercial and residential sectors in 1999, 2000, 2008 to 2019, the amount rounded to zero, so a price was not reported.
