The transportation sector consists of private and public vehicles that move people and commodities. Included are automobiles, trucks, buses, motorcycles, railroads, aircraft, ships, barges, and natural gas pipelines. Natural gas use reflects the fuel needed to move natural gas through a pipeline to end users in the residential, commercial, industrial, and electric power sectors. Since 1990, natural gas consumption also includes natural gas consumed as vehicle fuel.
Between 2018 and 2019, transportation sector energy use decreased less than one percent (0.13%) to 206.9 trillion British thermal units (Btu). Petroleum use increased 1.1 percent from 2018. Natural gas use decreased 24.2 percent and renewable energy use increased 1.8 percent. (Renewable energy consisted of ethanol.) If there was any consumption of coal, electricity, or residual fuel in 2019, the amounts were so small that the numbers rounded to zero in this table.
In 2019, nearly all of the transportation sector energy needs were met by petroleum products (93 percent). Natural gas met 3.7 percent, and ethanol met 3.4 percent of the energy consumed in the transportation sector.
Motor gasoline (51 percent), diesel fuel (46 percent), and jet fuel (2.5 percent) made up the majority of the petroleum products consumed by the transportation sector; each of the rest of the petroleum products comprised 1 percent or less of total petroleum products.
