Its contents are therefore discussed aecording to the followingstructure: (a) prospects for the developnent of the energy resources of developingcountriest (b) constraints on the development of the energy resources of thesecountriesi and (c) national and international policies. rI. PROSPECTS FOR THE DEVELOPMEM OF ENERGY RESOURCES IN DEVELOPING COUNTRIES A. potential of energy resources 6. Any estinate of reserves of energy resources is based on the geologieal andtechnological knowledge prevailinq at the time the estinate is derived, and thisknowledge changes over time. But variations in estinates at a particular time eanbe very large as well. t,/ In the following seetions the potential of the differentenergJt sources will be discussed in terms of the estimated availabilitv ofresources. 1.

**Analysis**
The text appears to be discussing the development of energy resources in developing countries, focusing on the potential of different energy sources, constraints on development, and national and international policies. It seems to be concerned with the economic and environmental implications of energy resource development, as well as the financing and investment requirements for such projects.
