Abstract :
Background and objective: The extraction and excessive consumption of natural resources and the increase in the emission of waste and pollution threaten the national economy. In the past few decades, the contribution of renewable energies has increased due to a wide range of factors, such as government regulations to promote the use of renewable energies, reducing the cost of installing renewable energies and increasing production capacity, oil price fluctuations, and the positive effects of renewable energies in reducing emissions. Carbon dioxide gas and innovation processes in the energy sector have increased. In this regard, the main goal of this study is to compare the impact of renewable energy on carbon dioxide emissions as an indicator of environmental quality in Iran and selected countries.
Materials and Methods: The present study is an applied, causal and inferential research method. The method and tool of collecting information and statistical sources is also the method of written documents, electronic information and filing. In this article is using the panel data method in selection countries and comparing and time series model in Iran in the period 2000-2021.
Findings: The results using the fixed effects method in the group of selected countries showed that renewable energy, individuals using the internet as an indicator of information and communication technology, human capital and governance index have a negative and significant effect on carbon dioxide emissions as an indicator of environmental quality. But economic growth does not have a significant effect on the quality of the environment. The results of estimating the model using the generalized least squares method in Iran showed that renewable energies, economic growth and governance index have a negative and significant effect, and human capital and individuals using the internet as an indicator of information and communication technology have a positive and significant effect on the quality of the environment.
Discussion and Conclusion: The comparison of the results in the group of selected countries and Iran showed that Renewable energies have a negative and significant effect on the emission of carbon dioxide gas as an indicator of the quality of the environment in the group of selected countries and Iran. With an increase of one percent in the consumption of Renewable energy on average, assuming that other conditions are constant, the amount of carbon dioxide gas emission in the group of selected countries has decreased by 0.17 percent and in Iran by 0.14 percent
The impact of new energies on the emission of carbon dioxide gas in the group of selected countries is higher than in Iran. Expanding the use of Renewable energies in the world plays an important role in reducing pollution and reducing greenhouse gas emissions. Because when Renewable energies are produced, nothing burns conventionally, in other words, it does not oxidize, and toxic and harmful gases are not produced. Therefore, the quality of the environment improves.
