The bituminous coal industry, its markets, and its production sites have changed over the past decade. An examination of the supply and demand situations, future potential coal energy supply areas in terms of total resources and sulfur content, and the effects environmental controls may have on the future demand-supply relationship for coal revealed that coal markets in the east will continue to decline, production from the western coal-producing region will increase at an excellerated rate, and western producers will expand existing coal markets and develop new ones, principally in the Midwest. Over the long run, all coal-producing regions should grow. This will be a consequence of (1) an economical stack gas system being developed, permitting the use of coals of higher than 1 percent sulfur, and (2) the desire for domestic sources of fuel rather than foreign sources.
