1940s, the fuel remained the world’s most important source of fossil energy, and
hence the leading primary fuel, until 1964 when its contribution was surpassed
by crude oil. By 1970 coal and crude oil supplied, respectively, about 30% and
40% of all fuel energy, by 1980 the relative gap had widened marginally to
roughly 29% and 41% and by the century’s end the two fossil fuels provided,
respectively, about 25% and 37% of all fuel energies (Figure 2.14). Recall that
all of these comparisons exclude the non-energy products and hence the oil
shares presented here are lower than those calculated (commonly but inaccur-
ately) by using gross energy content of crude oil.
