Ecological and economic efficiency of traditional and alternative methods of electrical energy production with the features of The Islamic Republic of Iran

Abstract

The problems of energy, environment protection and ecology play a major role in the development of economy strategy in any country. Most of the traditional power stations operating on organic fuels have a negative impact on the environment. Furthermore, there is a depletion of natural resources due to human activities. One of the ways to solve the problem of environmentally friendly energy production is to use alternative sources of energy. Based on the foregoing, the development of the strategy for the development of traditional and alternative energy must consider environmental and economic factors in a specific country. In the present work it was evaluated the environmental and economic efficiency of application of traditional and alternative energy with regard to the conditions of the Islamic Republic of Iran. The program packages RETScreen which is one of the most effective tools to accomplish the task was used. Calculations of cumulative cash flow from the operation of power plants using different types of primary energy are carried out using models of package RETScreen for assessing the input efficiency of various types of energy sources aiming to cover the intending growth in electricity demands and the environmental assessment with reference to different countries. The results of the study showed that the planning prospects of the development of energy systems in relation to the Islamic Republic of Iran to cover the expected growth in electricity demands it is advisable to use the alternative energy sources, and, first of all the generating capacity based on solar and wind energy.
