The impact of predicted demand on energy production

Abstract

Abstract. Energy is crucial for human life, a secure and accessible supply of power is essential for the sustainability of societies. Economic development and demographic progression increase energy demand, prompting countries to conduct research and studies on energy demand and production. Although, increasing in energy demand in the future requires a correct determination of the amount of energy supplied. Our article studies the impact of demand on energy production to find the relationship between the two latter and managing properly the production between the different energy sources. Historical data of demand and energy production since 2000 are used. The data are processed by the regression model to study the impact of demand on production. The obtained results indicate that demand has a positive and significant impact on production (high impact). Production is also increasing but at a slower pace. In this work, Morocco is considered as a case study. IntroductionThe energy demand should increase considerably in the coming years because of the increase of the population and the economic development (EIA, on 2007). Gradually as economics spend some concept of subsistence to that of industrial production or services, the lifestyles of numerous individuals will know of deep changes. The main increases of energy demand will be the fact of the developing countries where the percentage of the world consumption of energy should cross 46 to 58 percent between 2004 and 2030 (EIA, on 2007. It is planned that the energy consumption in developing countries will increase at an annual average rate of 3 percent between 2004 and 2020. In industrialized countries, where the state economies are mature and the population growth should be relatively weak, the energy demand will progress more slowly at the 0, 9 percent rate a year, although the starting point is much higher. The increase of the world demand for 2030 will be attributable in the electricity production and the fifth at the needs for transport, in particular in the form of petroleumbased fuels (EIA on 2007). The electrical energy can be an important element of any strategy wished to improve the environment provided that the consequences at the level of his production are mastered. Literature reviewThere are various types of conventional and no conventional sources of energy used for electrical power production. The system of solar and wind energy is one of the most important sources of energy. The exploitation of solar and wind energy became more and more necessary because of the nature modular and favorable to the environment [1]. The modeling of energy demand can follow either the approach with a variation of time or the approach with fixed coefficients. Nevertheless, he can be necessary to estimate the underlying statistical behavior of the parameters of energy demand before any significant inference. Z.

Effects of composition and pore evolution on thermophysical properties of Huadian oil shale in retorting and oxidizing pyrolysis

“…The important conclusions are as follows: (1) Montmorillonite transforms into kaolinite and illite in OP, and into illite to form an illite/montmorillonite mixed layer in AR. (2) The specific surface area and pore volume of semi-cokes are extremely low at low temperatures in AR, whereas numerous mesopores and macropores can be formed in OP, leading to significant increases in the specific surface area and pore volume even at low temperatures. (3) Variations in chemical composition and pore evolution of semi-cokes obtained via AR and OP affected their thermophysical properties.…”

“…The increase in energy demand and low levels of oil resources have necessitated urgent research on alternative energy [1,2]. Oil shale, a finegrained sedimentary rock containing organic matter (kerogen) that can be converted into shale oil and gas, has attracted considerable attention as an auxiliary energy source owing to its abundant reserves and wide distribution [3][4][5][6].…”
