Key: kWh = kilowatt hour; N = data do not exist; R = revised; P = preliminary.

Prior to 1984, the data in this table include the energy consumption of bus, heavy rail, light rail and trolley bus. Commuter rail, automated guideway, urban ferryboat, demand responsive vehicles, and most rural and smaller systems are excluded from the data during this period.

b Other nondiesel fuels includes consumption of propane (liquid petroleum gas) for years prior to 1984. For 1984 and after, other nondiesel fuels includes propane (liquid petroleum gas), liquefied natural gas, and other (bio/soy fuel, biodiesel, hydrogen, methanol, ethanol and various blends). Therefore, the data prior to 1984 are not comparable to the data for 1984 and after.
