Abstract

The need for development is increasing and the demand for energy is rising. The construction of new power plants has become necessary to meet this growing demand. To protect the environment and conserve finite fossil fuels, renewable energy sources are crucial to the transition to green energy production. Examining the impact of energy production on the environment is crucial, and not just in terms of financial, economic and geographical factors. The aim of this study is to understand the contribution of renewable and non-renewable power plants to the total emissions generated over a one-year operating period. The RETscreen analysis software was used to estimate the emission coefficient and a cost-benefit analysis method was used to evaluate the environmental impact. The value of each ton of carbon dioxide and the discount rate for environmental effects are key factors in estimating the emission coefficient of the different energy systems. Renewable energy systems have an emission coefficient of zero, while gas turbine systems, two-way gas engines, two-way biogas engines and coal-fired steam turbines have emission coefficients of 700, 747, 45 and 1,509 billion rials, respectively.
