This study examines and explains the long-term relationship between clean energy consumption (nuclear and renewable) and non-clean energy (fossil energy) and economic growth using panel data during the period 1980-2080. In order to investigate the relationship between variables in the long run, panel causality test has been used. Experimental results show that there is a collective relationship between the variables. According to the results, the revenue elasticity of nuclear energy consumption, renewable energy consumption and fossil fuel consumption is between zero and one, which indicates that nuclear energy, renewable energy and fossil fuels are essential commodities for countries. Also, with a one percent increase in nuclear energy consumption, renewable energy consumption and fossil fuel consumption, GDP will increase by 0.069 percent, 0.176 percent and 0.398 to 0.749 percent, respectively. Short-term causal analysis indicates a two-way causal relationship between fossil energy consumption and economic growth, nuclear energy consumption and renewable energy. The results also indicate a one-way causal relationship between renewable energy consumption and economic growth. Also, in the long run, there is a two-way causal relationship between economic growth, fossil fuel energy consumption and renewable energy consumption, and a one-way causal relationship from economic growth to nuclear energy consumption.

This study examines the interrelationships of clean energy, domestic and foreign capital, economic growth, and environmental quality in a group of developing countries during 1995-2018. In this regard, the GMM method has been used. To estimate the impact of domestic and foreign capital development, three different indicators such as foreign direct investment, stock markets, and credits allocated to the private sector have been used. The results show that the increase in clean energy by one to two percent, the emission of carbon dioxide by four, and the increase of foreign direct investment by one percent have increased economic growth. On the other hand, economic growth, while increasing clean energy consumption by an average of 11 percent, has also increased carbon dioxide emissions. Despite the positive mutual relationship between clean energy and economic growth, fossil fuels are still used more in the selected countries. Clean energy projects have lower efficiency and higher financing than other energy supply projects. Therefore, in developing countries, due to a lack of enough capital, few investments are made in these projects.

Although solar energy is one of the most important renewable energies in Iran that most areas of the country, especially the Central Desert, have considerable ability to use, but the random nature of this type of energy makes it difficult to predict its output power and may cause problems in the performance of the feed systems. For this reason, the use of energy storage systems for periods of less production than consumption is necessary to balance production and consumption. There are various technologies for solar energy storage, but before using them in Iran it is necessary to examine the capacity of these technologies in Iranian companies and decide on their basis. Absorption capacity is a process that helps organizations and companies in different industries and services to recognize the knowledge or technology and to attract, transfer and exploit it and achieve competitive advantage. In this study, it is tried to investigate the absorption capacity of existing technologies for solar energy storage and to select higher priority transmission technology by Grey Relational Analysis.

Foreign direct investment (FDI) and increased trade volume have been known as resources for capital accumulation and economic growth in developing countries. FDI and trade are also associated with  technology transfer, linkages with international markets, and transfer of management skills. However, increasing economic growth requires higher energy consumption, which leads to environmental degradation in these countries. This study probes the effect of foreign direct investment and trade openness on Carbon dioxide emissions (as an indicator of environmental quality) and clean energies in the selected developing countries using a panel-ARDL approach during 1971-2014. The findings of this study reveal that despite the positive and significant effects of direct foreign investment on economic growth and the use of clean energy, they have no significant effect on the environmental degradation in these countries. The results also show that trade openness has a positive and significant correlation with carbon dioxide emissions, while this variable has a negative and significant effect on clean energy consumption. Finally, the results of the study indicate that the speed of adjustment towards long-term equilibrium in this model is relatively slow.
