INTEGRATED NATIONAL ENERGY PLANNING (INEP) IN DEVELOPING COUNTRIES

Recent increases in energy prices have drawn attention to the importance of developing an integrated approach to energy sector planning, in contrast to the prevailing practice of uncoordinated planning in different energy sub-sectors. Integrated national energy planning (INEP) requires a clear definition of national objectives, in relation to which links between the energy sector, and activities in each individual sub-sector, may be analysed. Policy tools for achieving national goals include physical controls, technical methods, education and propaganda, and pricing. Use of these tools must be coordinated. The INEP procedure, which leads to an energy master plan, consists of several steps: determining the socio-economic background, supply and demand analysis, energy balance, and policy formulation. Initially INEP may be carried out at a relatively simple level, and later as data and analytical capabilities improve more sophisticated computerized modelling techniques could be implemented. The institutional structure should be rationalized by setting up a central energy authority (CEA) or ministry of energy (MOE), with its principal focus on energy planning and policy formulation. Les récentes hausses des prix de l'énergie ont révélé l'importance de l'élaboration d'une approche intégrée de la planification du secteur de l'énergie contrastant avec les pratiques courantes de planification non coordonnée qui existent dans les différents sous-secteurs de l'énergie. La planification nationale intégrée de l'énergie (PNIE) requiert une définition précise des objectifs nationaux à la lumière desquels on pourra analyser les liens existant entre le secteur de l'énergie et les autres secteurs de l'économie, les rapports entre les sous-secteurs à l'intérieur du secteur de l'énergie et les activités de chaque sous-secteur pris individuellement. Les contrôles directs, les méthodes techniques, l'enseignement, la publicité et la fixation des prix sont au nombre des moyens d'action dont dispose une telle politique pour parvenir aux objectifs nationaux. La procedure de la PNIE qui conduit â l'élaboration d'un plan-cadre en matière d'énergie comprend plusieurs étapes: détermination du contexte socio-économique, analyse de l'offre et de la demande, bilan énergétique et formulation politique. Dans une première étape, la PNIE peut être effectuée à un niveau relativement élémentaire et par la suite, au fur et à mesure que les donnés et les méthodes d'analyse s'améliorent, des techniques informatiques plus avancées en matiére d'établissement de modèlas pourraient étre utilisées. Le cadre institutionnel devrait être rationalise par la creation d'une autorité centrale de l'énergie ou d'un ministêre de l'énergie ayant pour tâche principale la planification de l'énergie et la formulation de politiques. Los recientes aumentos de los precios de energía resaltan la importancia de un enfoque integral en la planificación del sector de energía, en contraste a la practice generalizada de la planificación por subsectores de energía. La Planificación Energética Nacional Integrada (PENI) requiere una clara definición de objetivos nacionales en relación a los cuales pueden analizarse las relaciones entre el sector de energía y el resto de la economía, las inter-acciones entre los subsectores de energía y las actividades dentro de cada subsector. Las herramientas de política para alcanzar objetivos nacionales incluyen controles físicos, métodos técnicos, educación y propaganda, y precios. El procesco de PENI, que da como resultado un Plan Maestro de Energia, comprende varias etapas: determinación de las condiciones socioeconómicas, análisis de la demanda y la oferta, balance energético, y formulación de políticas. Al comienzo la PENI puede llevarse a cabo a un nivel relativamente simple; luego, cuando la información y la capacidad analítica mejoran se pueden implementar técnícas de modelización a base de computadoras. El marco institucional debe racionalizarse mediante la creación de una autoridad energética central o ministro de energía, encargado en particular de la formulación de políticas y la planificación energéticas.     

CONFLICTS IN ATTAINING NATIONAL GOALS FOR BOTH WATER QUALITY AND ENERGY PRODUCTION1

ABSTRACT: The “policy environment” is defined herein as the institutional setting in which planning is conducted and policy decisions are made with regard to meeting two of the Nation's high priority goals: water quality protection and energy independence. The simultaneous pursuit of these goals has resulted in numerous conflicts among the energy industry, environmentalists, and government. An analysis of selected energy development-water quality conflicts shows that these conflicts can be described in terms of one or more of the following policy environment characteristics: resource scarcity, sense of urgency, lack of experience, administrative complexity, uncertainty about future policies and regulations, technological complexity, and uncertainty about impacts. These characterics provide a useful framework for formulating potential strategies for the resolution of energy development-water quality conflicts.     

NUTRIENT BALANCES FOR THE EVALUATION OF NUTRIENT SOURCES IN WATER QUALITY MANAGEMENT1

ABSTRACT. This paper describes the methodology for a nutrient balance to evaluate the sources and distribution of nutrients in a small river basin. Loadings for total nitrogen and phosphorus are calculated from measured nutrient concentration and river discharge data. Using a special retrieval program and a data storage and processing system, loadings are accumulated over a given time period to allow for time of passage through the basin and seasonal changes in nutrient distribution. Nutrient balances are made with the accumulated loadings to obtain the relative contribution of each nutrient source and the retention of nutrients within the basin through sedimentation and aquatic growth. The methodology has been used to study nutrients in the Qu'Appelle River Basin, Saskatchewan, Canada.     

ENERGY DEMAND MANAGEMENT

The article sets out the global framework and the World Bank's current projections of future energy demand by the developing countries. It examines the role of energy pricing policies in achieving a reduction of this demand without a reduction in economic growth. The article then discusses the relative roles of government and the private sector in energy demand management and follows this with a discussion of potential energy savings through pricing and other means in the four major energy using sectors: the household sector, transport, industry and electric power. The paper concludes with an assessment of the overall impact of energy demand management in the next ten years. Cet article établit le cadre global et les projections actuelles de la Banque Mondiale concernant la demande future en énergie des pays en développement. II examine le rôle que joue la politique des prix dans la réduction de cette demande sans toutefois entraïner une diminution de la croissance économique. L'article traïte ensuite des rôles relatifs du gouvernement et du secteur privé en ce qui concerne la gestion de la demande énergétique et se poursuit par une discussion des économies réalisables en matière d'énergie par un système de prix et par d'autres moyens dans les secteurs utilisateurs d'énergie les plus importants: les ménages, le transport, l'industrie et l'electricité. L'article se termine par une évaluation de la portée générale de la gestion de la demande énergétique dans les dix prochaines années. El articulo expone el marco global y las proyecciones de demanda futura de energia realizadas por el Banco Mundial para los países en desarrollo. Examina el rol de la política de precios para alcanzar la reducción de esta demanda sin reducir el crecimiento economico. El articulo analiza luego los roles relativos del gobierno y del sector privado en la administración de la demanda de energía y continúa con la discusion del ahorro potencial de energia a través de política de precios y otros medios én los cuatro sectores mayores consumidores de energía: doméstico, transporte, industria y electricidad. El articulo termina con una evaluación del impacto general de la administración de la demanda en los próximos 10 años.     

GEOTHERMAL ENERGY IN TRANSITION

At a time when future sources of energy are under close scrutiny, both in terms of availability and suitability, geothermal energy ranks among the candidates for inclusion in any appraisal of alternative forms of supply. The use of geothermal energy for the production of electricity and for supplying domestic and industrial heat is a comparatively recent phenomenon, and its application remains closely constrained by favourable geological conditions. Yet exploration in several countries shows that geothermal energy may emerge as an important adjunct to total energy supply in many localities. McNitt outlines some of the economic and technological parameters of this energy source. Small scale geothermal power stations are more economic and less capital intensive than conventional plants, which make them of particular interest for developing countries with small electricity systems and competing demands on limited capital resources. The principal capital expenditures in the development of geothermal sources include exploration, steam production, installation of generating plant and the cost of effluent disposal. The wider use of low grade geothermal heat is also examined, in addition to the environmental problems occurring to the development of geothermal energy. The scope for technical co-operation in the development of geothermal energy is substantial, and it is likely that this source of energy will undergo more intensive development on the local scale in the future.     

THE LONG-RANGE ENERGY PERSPECTIVE

The author reviews general questions affecting energy projections and goes on to examine reserve forecasts for each type of energy. The last part of the paper considers consumption forecasts and makes an assessment of the likely situation in the year 2000.     

THE NATIONAL WATER COMMISSION REVISITED1

ABSTRACT: In 1973 the National Water Commission concluded its five-year study of national water policy by issuing a massive report containing over 200 recommendations for improvements in the way the Nation deals with its water resources. The Carter Administration is now engaged in another water policy review which incorporates many of the policies espoused by the National Water Commission. In this paper, presented at the 13th American Water Resources Conference in Tucson in November of 1977, the author describes the work of the National Water Commission and the actions taken on its recommendations.
