Asia) and the integration process is under way. The hypothesis of creation of the Global Electrical Network has been studied in the recent years [3]. Volumes of coal transported between regions is steadily increasing. Therefore, we can expect that the world-wide electric power, gas and coal supply and even nuclear energy systems will be created. The latter will include large international (inter-regional) projects for reprocessing and storage of nuclear fuel and long-term disposal of high-level actinides. This leads to the idea of possible integration of the indicated specialized energy- systems into the multi-product World Energy System [4], A somewhat similar idea has earlier been expressed by W. Haefele and W. Sassin [5], The concept considered below is a further step in this direction and differs from [5] in some aspects. It can be one of the possible options for the future global energy development. The multi-product World Energy System (WES) is expected to have the following features [4]: • WES is a single technically and technologically interconnected aggregation of power, gas, oil, coal, and heat supply systems; • WES integrates in fact the world power, oil, gas, coal and nuclear systems that already exist or may be installed in the distant future; • WES is viewed as a possible way of further development of centralized energy supply; • technological unity of WES is its most important property that requires the operation control and development management of WES as a whole; • WES can be created only on the base of international efforts and cooperation. Large energy centers (with the capacity of tens of GW) which are designed for production of electricity and heat, synthetic fuel, chemical and other products are basic elements of WES integrating specialized energy systems (of power, gas, oil and coal supply) into technological unity (see Figure 1). Each center (possibly located on a certain restricted territory) can provide several countries with energy, fuel and raw materials. Creation of such centers is possible on the basis of international cooperation only. The following examples of such centers can be pointed out: • gas-chemical complexes constructed in the Near East, North Africa, West Siberia, etc. for production of electricity, liquid fuels, chemical raw materials, etc.; • nuclear centers which can produce electricity, synthetic liquid and gaseous fuels as well as chemical and other products from coal, shales, bituminous sands, etc.; • energy complexes on the base of large coal fields (in Siberia, China, Australia, etc.) for production of electricity and synthetic fuels;
