The energy and economy interactions are so advanced that they are in today's economic literature, the amount of energy resources in countries, the amount of primary energy supply and consumption per capita and the per capita kilowatt-hours of electricity consumption have become one of the indicators for comparing the level of development of countries. Fossil fuels cause social costs through environmental pollution and the phenomenon of global warming; the average solar radiation of Kerman daily has 5.2 kilowatt-hours per square meter per day, which has the potential to use solar energy in various industrial and household sectors. The purpose of this article is to assess the economic and environmental assessment of photovoltaic systems in providing electricity to a commercial tower with an average consumption of 32000 kilowatt-hours of electricity per day in Kerman using a life-cycle cost method. In the first scenario, all system costs are paid by the consumer, and in the second scenario, it is assumed that 50% of the initial investment cost was paid by the government, and the rest would be in the form of a loan at a rate of 2% with the repayment period of ten years old. The results show that the use of photovoltaic systems in order to produce electricity under the first scenario does not have economic justification, but with the support of the government, this scheme has economic justification.

It is expected that fuel price increase for power plant uses would lead into an electricity price increase and consequently electricity production, emissions pollutions and greenhouse change. To quantify these effects we develop a system dynamics model for the electricity market in Iran consisting of demand, price and generation modules. The purpose of this paper is to investigate the effects of fuel reforming plants on emissions pollutions and greenhouse. To quantify these effects we develop a system dynamics model for the electricity market in Iran and this model is solved and simulated using POWERSIM software. According to the results, , if the subsidized prices for power plant fuel uses are still maintained, in the framework of the model Emissions pollutions and greenhouse, assuming growth rates at the end of period 5 and 8 percent, respectively, in the (-%1) and 3%. With modified fuel delivery price to power plants, the amount of environmental pollutants, assuming growth rates at end of period 5 and 8 percent, respectively, in the (-1) percent and (3) percent. In the final part of the paper, effect of increase on PowerEfficiency in the model has been studied, Assuming growth rates of 5 and 8 percent, emissions pollutions and greenhouse rate are expected to reach the end of the period to (-0.6) percent and (+0.4) percent compared with price reform, respectively.
