Emission factors of CO2, SO2 and NOx emitted from Irans thermal power plants are fully covered in this paper. To start with, emission factors of flue gases were calculated for fifty thermal power plants with the total installed capacity of 34,863 MW regard to the power plants operation characteristics including generation capacity, fuel type and amount and the corresponding alterations, stack specifications, analysis of flue gases and physical details of combustion gases in terms of gKWh-1. This factor was calculated as 640, 2.75 and 2.4 gKWh-1 for CO2, SO2 and NOx respectively. To achieve an accurate comparison, these values were compared with their alternatives in North American countries. According to this comparison, emission factor of flue gases emitted from Irans thermal power plants will experience an intensive decline if renewable, hydroelectric and nuclear types of energy are more used, power plants efficiency is increased and continuous emission monitoring systems and power plant pollution reduction systems are utilized.

Considerations & intergenerational justice has been of less value. The present research is conducted with the aim of determining and ranking energy consumption policy criteria in Iran to reach a intergenerational justice. Experts and professors working in the field of energy policy and planning from Ministry of Energy, Institute of International Study of Energy and the Sharif University composed the scope of the poll of this study. After studying the relevant literature, certain criteria for energy policy while bearing in mind ethical considerations and intergenerational justice were determined. The research method in light of goal is utilitarian one, from the content viewpoint is heuristic, and from the data gathering method is processing one. In all levels of the application AHP Technique, the software Expert Choice was resorted to. In this prioritization, the stability criterion with the relative weight of 0.488 acquired the highest weight, followed by that sufficiency with 0.240, participation with 0.139, and coherency, respectively. Ultimately, after mixing and comparing the options, renewable energies with the relative weight of 0.491 was the best option, followed by fossil fuels with 0.28, and nuclear energy with 0.229..

The present research aim’s to investigate of the relationship between the social acceptance of solar energy systems and their effective factors in Tabriz. The general view governing the research is quantitative and according to the purpose of research is type of applied and in terms of the amount of supervision and control is method of field and in terms of information collection is descriptive and causal, communication. And also, the methodology on the base of it’s nature is method of survey. For implementing this aim, 384 persons were chosen among the Tabriz citizen’s by using the single stage cluster random sampling. They were asked to response to the questionnaire of provided.The amount of influencing of effective factors in accepting of using solar system by people investigated through descriptive and inferential test. The results show that social acceptance of solar system of Tabriz citizen’s is affected by five factors such as: education, income, occupation, marital status and their knowledge.

The aim of this study was to identify effective barriers on using renewable energy in agricultural sectors of Iran. In order to collect the required information was used from interviews with experts and university professors, documents and internet search. Data collecting tools was questionnaire. In this study, barriers such as education, technical, economic, social and regulatory were investigated. Based on research findings and using path analysis some factors such as technical barriers, economic barriers and social barriers directly and factors such as education and regulatory barriers have influenced indirectly on using renewable energy by farmers.

The prevalence of coronavirus at the end of 2019, which continues to this day, has been charged in various respects around the world, some of which operate irreparably and others can compensate. compensate for the slow process. On the other hand, the global event known as the Corona crisis has painted a picture of the future of energy in the energy sector, it examines and analyzes the conditions and experiences of this crisis, resulting in faster and more alert emissions. Resist future changes in the global energy industry, sustainable development, and the economy. Therefore, this report has been approached by changing the energy change in the world, and finally looks at the state of energy during the Corona crisis and gives recommendations to face the picture. about the world's energy future. It is one of the most important agreements for the implementation of international agreements and treaties aimed at increasing the sale of more oil and natural gas, leading to increased government revenue and, ultimately, required capital gain. to invest in energy. On the other hand, reducing hidden energy subsidies could also reduce the dependence of some national industries on oil and gas and these subsidies in the areas of low carbon, research, and innovation to support growth. share of innovation, especially in transportation, power supply, heating, and navigation.

High energy consumption in Iran along with the high emission of air pollutants (local pollutants and greenhouse gases) are among the main problems in Iran's transportation sector. Nowadays, in the developed countries of the world, the use of low-consumption and low-emission cars, along with the use of fuel mixed with ethanol or the use of hybrid and electric cars, are on the agenda as ways to deal with the problems of the energy sector. In our country, due to the fact that most of the electricity produced is obtained from the burning of fossil resources, some believe that the use of electric cars will result in the emission of pollutants. Therefore, in this article, the analysis of wheel wells for all types of cars (internal combustion, electric and hybrid) in the country is discussed. In the discussion of electric cars, the amount of energy consumption and emission of pollutants in the production of lithium-ion batteries is also considered.
