Footnotes:

a Includes supplemental gaseous fuels that are commingled with natural gas.

b Beginning in 2013, includes biodiesel blended into distillate fuel oil. Beginning in 2021, includes biodiesel product supplied.

c Hydrocarbon gas liquids, assumed to be propane only.

d Beginning in 1993, includes fuel ethanol blended into motor gasoline. There is a discontinuity in the expenditure series between 2014 and 2015 because of changes in consumption estimates from the source. See consumption technical notes, Section 4.

e Includes small amounts of petroleum coke not shown separately.

f Wood, wood-derived fuels, and biomass waste. Prior to 2001, includes non-biomass waste.
