Petroleum products accounted for two-thirds of the energy consumed in 1990, but Nigeria also had substantial resources in the form of hydroelectricity, wood, subbituminous coal, charcoal, and lignite. In the 1980s, most cooking was done with wood fuels, although in urban areas petroleum use increased. Coal, originally mined as fuel for railroads, largely had been replaced by diesel oil except in a few industrial establishments. Coal production fell from 940,000 tons in 1958 to 73,000 tons in 1986, only a fraction of 1 percent of Nigeria's commercially produced energy.

Tin and columbite output fell from the 1960s through the 1980s as high-grade ore reserves became exhausted. A fraction of the extensive deposits of iron ore began to be mined in the mid1980s , and uranium was discovered but not exploited. Almost none of these minerals left the country, however, as petroleum continued to account for virtually all of Nigeria's mineral exports.

Mining contributed 1.0 percent of GDP in FY 1959, on the eve of independence. This sector's share (including petroleum) stood at more than 14 percent in 1988. Mining's general upward trend since l959, as well as the fluctuations in the size of its contribution to GDP, can be attributed to the expansion and instability of the world oil market since 1973.
