Abstract

[eng] A Forecast of Energy Consumption in 1985 - As a part of the preparation of the VIIIth Plan, the INSEE has used a number of what are called « regulation » scenarios to make a detailed forecast of energy consumption in 1985. The forecast predicts that growth will be based on limited use of imported energy. There are several reasons for this. First, although the use of coal will continue to decline, it will do so at a slower rate. However, the key factor will be a substantially reduced oil consumption. On the other hand, electricity will continue to represent a growing percentage of overall consumption, although its growth rate should fall off considerably. As far as the production system is concerned, the Propage model makes it possible to provide a detailed analysis of the extremely varied situations in some 36 sectors. This analysis shows, however, that most of the energy saving should come more from specific efforts within certain sectors, such as the chemical industry or the ore or iron industry, rather than from a redistribution of activities. Households should tend to increase their energy consumption as their standard of living grows, as in the past. However, it is likely that the rising cost of oil and specific measures favoring energy saving can encourage them to limit energy spending. [fre] Dans le cadre de la préparation du VIIIe Plan, l'INSEE a réalisé à partir de scénarios dits de « régulation » une projection détaillée des consommations énergétiques à l'horizon 1985. La croissance ainsi projetée apparaît particulièrement sobre en énergie importée. A cela plusieurs raisons : tout d'abord le déclin du charbon se poursuivrait, à un rythme ralenti toutefois; mais surtout, la consommation de pétrole se réduirait considérablement; en contrepartie, et bien que son taux de croissance fléchisse nettement, la consommation d'électricité accroîtrait largement sa part. En ce qui concerne le système productif, le modèle Propage permet une analyse très détaillée des situations des 36 branches, qui apparaissent très variées. Il ressort cependant que l'essentiel des économies devrait provenir davantage des efforts particuliers de certaines branches, comme la chimie ou les minerais et métaux ferreux, que d'une redistribution des activités. Quant aux ménages, leur tendance à augmenter leur consommation d'énergie avec leur niveau de vie se maintiendrait. Mais il semble que la hausse du prix du pétrole et des mesures spécifiques d'incitation aux économies puisse les encourager à limiter leurs dépenses énergétiques. [spa] Una proyección de los consumos energéticos en 1985 - En el marco de la preparación del VIII° Plan, el INSEE llevó a cabo a partir de scenarios llamados de « regulación » una proyección pormenorizada de los consumos energéticos a la vista del año 1985. El crecimiento proyectado así aparece particularmente moderado con relación a energía importada. Hay varias razones para ésto : el ocaso del carbon proseguiría a ritmo ralentizado no obstante; el consumo de petróleo sobre todo iría menguando considerablemente. En cambio, y si bien su tasa de crecimiento desciende netamente, el consumo de electricidad se incrementaría patentemente. Por lo que se refiere al sistema productivo, el modelo Propage facilita un análisis sumamente pormenorizado de las situaciones de las 36 ramas, las que aparecen muy variadas. Sobresale, sin embargo, que lo esencial de las economías debería de resultar más pronto de los esfuerzos particulares de algunas ramas, tales como productos químicos o minérales y metales férreos que de una redistribution de las actividades. En cuanto a hogares, su tendencia a incrementar su consumo energético al propio tiempo que su nivel de vida, se iría manteniendo. Mas, parece ser que el alza del precio del petróleo así como medidas específicas de incitación a ahorrar energía pueda animarles a limitar sus gastos energéticos.
