7 per cent, reaching 270 gfl in the year 2000. Geothermal power is likely to become increasingly important and to reach an aggregate capacity of 5 to 7 Gvt by the end of the century. Finally, it is expected that, with the possible exception of power generated by alcohol produced frorn sugar-cane in the energy-deficient developing countries, the other new and renewable sources of energy will not make a significant contribution in eitber group of developing countries within this century. 29. Since meeting energy needs will not be a problem for the energy-exporting countries , A/ discussion of the energy balance through the end of the century will focus on thienergy-deficient developing countries. Based on projections of energy consumption and production in this group of countries, donestic production of comrnercial energy, which in 1980 covered 48 per eent of total consumption needs, is expected to meet 63 per cent of requirements in the year 2000. It should be noted, however, that even with a higher ratio of energy self-sufficiency, the energy-deficient developing countries will still have to increase their imports frorn 5.3 mbdoe in 1980 to 12-7 mbdoe in 2000 (E/L983/9I and corr'l, table 15)' III. CONSTRAINTS ON THE DEVELOPMENT OF ENERGY RESOURCES IN DEVELOPING COUNTRIES A. Financial constraint 30. In order to realize the projected production increases in the various energy sources in developing countries during the period 1982-2000, an average annual investment need of $uS 92 billion (1982 values) has been projected (A/39/420 ancl Corr.1, table 1). Based on past trends of tbe relative contributions of the domestic energy enterprises of developing countries ry and foreign energy companies, U it has furtber been estimated tbat of the $92 billion needed $78 biflionlitt bave to be invested by domestic enterprises and $I4 billion by foreign companies (A/39/420 and Corr.1, table 2).
**Analysis**
The text discusses the energy needs and production of developing countries, highlighting the importance of domestic production and the need for significant investment to meet energy demands. It also touches on the role of international energy companies in supporting energy development. The text's focus on the economic aspects of energy production and the investment required to meet energy needs suggests that it is closely related to economic development and natural resources.
