As coal is considered as a substitute for other fuels, more serious attention is being given to the environmental impacts of the whole coal fuel cycle: mining, transport, storage, combustion and conversion. This volume presents an up-to-date account of these environmental impacts and the recent developments to combat and control them. A feature of the book is the way in which it discusses not only the experience and developments in North America and Western Europe but also presents much information made available for this study on the developments in the socialist countries of Eastern Europe.

Coal in the International Energy Scene

Publisher Summary

This chapter provides an overview of coal in the international energy scene. Growing internationalization of coal will make it a more dependable source of energy with less reliance on a limited number of suppliers. Although coal deposits are regionally dispersed, an increasing concentration of control over production and trade may occur. A significant growth of trade will give rise to financing requirements equivalent to about 4% of overall investment requirements in Organization for Economic Co-operation and Development (OECD) countries. This can continue over a period of two decades or more, but sudden surges in financing requirements will compete with other industrial investment needs through increases in interest rates. In developing countries, financing problems are likely to be the most severe; therefore, emphasis will continue to be on private investment in export projects. Concentration of control will be encouraged by the more complex and coordinated planning required in international trade, including expertise in marketing, finance, transportation and, in particular, by the need to reduce the risks inherent in long-term coal infrastructure projects.

1 Introduction

The utilization of coal as an energy source, both by means of the steam engine and in the form of coke, was a major characteristic of the first Industrial Revolution. It was on coal that nations built their industrial power in the nineteenth and early twentieth centuries. As early as 1860, Great Britain was producing over 80 million tons of pit coal, and it is probably not an exaggeration to say that, with the control of the oceans and overseas dominions, coal made her the dominant industrial power for several decades. Until the First World War it was the main coal-producing nations that held the world’s key positions. In 1913 Great Britain, Germany, France and the USA between them produced almost 90 % of the coal extracted in the whole world, and this production accounted for virtually all the world’s energy supply. Throughout previous decades a 3 % annual growth rate bore witness to the vigour of the industrial boom. Oil, however, was beginning to appear on the American market, and its use as a fuel was inconspicuously preparing the way for what was later to be one of the great mutations of the energy market.

Subsequently, the world entered a long period of disorder and trouble. There were two World Wars, an unprecedented energy crisis, and a massive invasion of oil into the energy market of the United States, which became the leading producer and exporter. The result of this shift to oil was a reduction in the share of coal in the world’s commercial energy consumption from 61 % in 1950 to 51 % in 1960 and 35 % in 1970. The major transition took place in the mid-1960s. By 1967 oil had overtaken coal’s global market share. This pattern was not uniform throughout the world; in the USSR rapid industrial expansion continued to be founded on coal.

After the Second World War oil production began to develop mainly outside the industrialized world–in Latin America, the Middle East, and later in Africa. The USA became, like Western Europe, an energy importer. A new balance in the world energy market came into existence based on the transfer of the developing countries’ excess production to the deficient markets of the industrialized nations and by 1970 coal accounted for about 35% of the world’s total commercial energy consumption (UN, 1978).

There was an exceptionally rapid and regular growth in the wealth of both the CMEA (Council for Mutual Economic Assistance) and the OECD (Organization for Economic Co-operation and Development) countries. World energy requirements increased with this rapid economic progress at about 4 % per year in the 1950s and 1960s, but total coal production increased only 2 % per year over this period. Solid fuels now account for no more than 30% of the total world energy supply and only 21 % in Western Europe (AGIP, 1980). The leading role on the developing world energy scene was played by liquid hydrocarbons, with new discoveries being made and decreasing prices mirroring the abundance of supplies.

If this history of global primary energy substitution between 1860 and 1975 were used to project market shares into the future, coal would be credited with only 10% by the turn of the century (McDonald, 1981), but something of a crisis arose in the early to mid-1970s. Between 1973 and 1979 the market price of oil rose, in real terms, several-fold, producing a severe challenge to the energy balance which had prevailed for 20 years. Thus intense interest came to be expressed in forms of energy which could act as a substitute for petroleum. The large and diversified resource base of coal, as well as its relative cheapness in relation to other fuels, led to a belief in the return of coal following its postwar decline (IEA, 1978; Wilson, 1980; World Bank, 1979). A period of gradual reversion following its partial replacement by oil was expected.

These predictions of a rapid rise in coal demand have more recently been affected by industrial recession in Western countries and by increased conservation of energy. Industrial restructuring has suggested that a previously supposed link between economic growth and energy use was unfounded (Pindyck, 1979). Future trends in coal production, consumption and trade cannot be predicted accurately and extreme difficulties exist in distinguishing between temporary effects on the international energy scene and those which will result in long-term changes (Long, 1982; Prior, 1982). Coal has now been established as a relatively attractive fuel in many industrial applications, but its overall prospects will depend on economic growth in the major industrialized regions of the world and its acceptability from a social and management point of view. The timing, rate and extent of the introduction of new coal conversion technologies have become particularly uncertain because of trends in relative energy prices and industrial recession.

However, one important change which is occu...
