[en] The fundamental concepts on energy and the different forms in which it is manifested are presented. Since it is possible to transform energy in a way to other, the laws that govern these transformations are discussed. The energy transformation processes are an essential compound in the capacity humanizes to survive and be developed. The energy use brings important economic aspects, technical and political. Because this, any decision to administer energy system will be key for our future life

[en] Object of sciences and technologies, energy plays a major part in economics and relations between nations. Jean-Louis Bobin, physicist, analyses the relations between man and energy and wonders about fears that delivers nowadays technologies bound to nuclear energy and about the fear of a possible shortage of energy resources.

[en] The energy demand during the next century due first of all to the expected growth of population necessitates more efficient technologies and huge investments. The production of nuclear energy requires higher safety as well as reduction of costs. A new form of partnership between the developed and developing countries is needed for transferring capital and technologies at special framework terms in order to avoid errors in the process of transition. The Energy Forum'99 highlights the current problems of Bulgarian energy branch and the projects for its future including better utilization of the existing energy resources, for development of new or renewable energy sources, not well utilized at present, and to harmonize the sector with better environmental protection. The most important problems discussed are: 1. Structure and restructuring strategy of the energy sector. Prices and tariffs. Privatization aspects. Construction of new replacement generating capacities; 2. Thermal power plants; 3. Nuclear power plants; 4. District heating and natural gas supply; 5. Efficient energy utilization; 6. Renewable energy sources; 7. Environmental protection and 8. Education

[en] The general equilibrium energy end use model proposed, uses linear programming as te basic and central element to optimization of variables defined in the economic and energy areas of the country related to a four factors structure: Energy, Raw Material, Capital and Labor, and related to the sectors: Residential, Commercial, Industrial, Transportation and Import/Export. Input-Output coefficients are defined in an input-output matrix of processes representing the supply of Electricity (generated by nuclear- not available in Chile-hydro, gas, fuel-oil and coal), Petroleum, Imported Natural Gas (transported and distributed) National Natural Gas, LPG, Coal, Wood and representing a demand of Residential, Commercial, Industrial, Transportation and Import/Export. There is an interaction of the final demand composition, the prices of capital, labor and taxes with the levels of operation for each process and the prices of goods and services. In addition to the prices of fuels for each annual period, to the supply and demand of energy and to the total demand it can forecast the optimum coefficients of the final demand. If the data to be collected result reasonably complete and consistent, the model will be useful for planning. A special effort should be placed in specifying a certain number of typical energy activities, the available options for fuels, the selection of them attending rational market decisions and conservation according to well known economical criteria of substitution. To simulate the process of options selection given by the activities and to allow substitutions, it is possible to introduce the logit function characterized by a Weibull distribution and the generalized substitution function characterized by the constant electricity. The model would allow, assuming differents scenario, to visualize general policies in the penetration of energy technologies. To study the penetration of electric energy generated by nuclear, in which the country does not have data, parametric perturbation could be introduced to foreign data (author)
