"Travel — Four categories of motorized travel (denoted by “T”
in the table) — cars and other passenger vehicles, air travel,
road pavement and recreational vehicles — account for just
over half (51%) of U.S. petroleum consumption. Auto and air
travel together account for more than half of the oil savings in
both plans.
Freight — The four major categories of goods movement —
trucks, ships, rail and air — together account for 17.5% of
U.S. oil use. Most of this sector lies beyond the reach of
behavior by individuals, and we target it only in the 10% Plan.
Heat — Just under 15% of the oil is burned to provide heat,
either as a means (factory or refinery process heat, or
electricity generation), or as an end in itself (space or hot
water heating). All four categories offer opportunities for
saving oil through personal conservation steps, as we discuss
below.
Miscellany — The remaining four categories — chemical
feedstocks, agriculture, military use and construction
machinery — total almost 16% of U.S. oil usage. Only in
feedstocks are there opportunities for immediate savings
through changes in behavior."
