Iran, endowed with abundant renewable and non-renewable energy resources, particularly non-renewable resources, faces challenges such as air pollution, climate change and energy security. As a leading exporter and consumer of fossil fuels, it is also attempting to use renewable energy as part of its energy mix toward energy security and sustainability. Due to its favorable geographic characteristics, Iran has diverse and accessible renewable sources, which provide appropriate substitutes to reduce dependence on fossil fuels. Therefore, this study aims to examine trends in energy demand, policies and development of renewable energies and the causal relationship between renewable and non-renewable energies and economic growth using two methodologies. This study first reviews the current state of energy and energy policies and then employs Granger causality analysis to test the relationships between the variables considered. Results showed that renewable energy technologies currently do not have a significant and adequate role in the energy supply of Iran. To encourage the use of renewable energy, especially in electricity production, fuel diversification policies and development program goals were introduced in the late 2000s and early 2010s. Diversifying energy resources is a key pillar of Iran’s new plan. In addition to solar and hydropower, biomass from the municipal waste from large cities and other agricultural products, including fruits, can be used to generate energy and renewable sources. While present policies indicate the incorporation of sustainable energy sources, further efforts are needed to offset the use of fossil fuels. Moreover, the study predicts that with the production capacity of agricultural products in 2018, approximately 4.8 billion liters of bioethanol can be obtained from crop residues and about 526 thousand tons of biodiesel from oilseeds annually. Granger’s causality analysis also shows that there is a unidirectional causal relationship between economic growth to renewable and non-renewable energy use. Labor force and gross fixed capital formation cause renewable energy consumption, and nonrenewable energy consumption causes renewable energy consumption.

Renewable energy plays a crucial role in increasing economic growth while reducing carbon dioxide emissions. The aim of this study is to examine the interaction between renewable energy consumption, economic growth and carbon dioxide emissions for selected Middle East and North Africa countries. For this aim, panel vector autoregression approach are used in the study. The annual data used in this study cover the period from 1988 to 2010 for Middle East and North Africa countries. Firstly, second generation unit root test are used to investigate stationarity properties of the variables and second generation panel cointegration test is applied to the data under consideration because of the cross-sectional dependence. Then a panel causality approach is proposed to examine the causal relationship between the variables. Finally, panel vector autoregression model, impulse-response and variance decomposition analysis are applied using generalized moment methods. The finding of this study shows that there is a bi-directional causality between growth and renewable energy consumption, which is consistent with the feedback hypothesis in terms of the energy consumption-growth nexus. It is found the evidence of unidirectional causality from carbon dioxide emissions to renewable energy consumption and from growth to carbon dioxide emissions. It is also found that the responses of growth to a shock of energy consumption are positive and the impact of renewable energy consumption on carbon dioxide emissions is negative.

The main purpose of this study is to investigate the causal relationship among renewable energy, nuclear energy consumption, economic growth, and CO2 emissions for selected OECD countries over the period 1980 to 2013. All variables are found to be cointgrated.Results of Granger causality show long-run relationship from GDP, renewable energy consumption and nuclear energy consumption to CO2 emissions, from CO2 emissions, GDP, to renewable energy consumption, from emissions, GDP to renewable energy, and from CO2 emissions GDP and nuclear energy consumption.In short run, results show that there exists bidirectional causality between GDP and CO2 emissions, and unidirectional causality running from renewable energy consumption to GDP. Also unidirectional causality running from renewable energy consumption to CO2 emissions without feedback but no causality running from nuclear energy consumption to CO2 emissions was found. This evidence suggests that renewable energy can help to mitigate CO2 emissions, but so far, nuclear energy consumption has not reached a level where it can CO2 emissions.

Abstract Previous studies have done more research on the relationship between carbon emission reduction, energy consumption and economic growth in specific countries or regions, which rarely consider the issue of heterogeneity between countries or regions, and also lack the refinement of energy consumption categories. Using panel data from 2000 to 2017,this paper divided the top 28 global carbon emission countries into developed countries and developing countries, and explores cointegration and causality between renewable energy consumption,non-renewable energy consumption, economic growth and carbon emission. Results suggested that there is a two-way causal relationship between carbon emissions and economic growth in all economies. There is a two-way causal relationshipbetween economic growth in developed countries and consumption of renewable and non-renewable energy, while there is no significant relationship between economic growth and energy consumption in developing countries. There is a two-way causal relationship between carbon emissions and renewable energyin all economies, but there are significant differences; there is a two-way causal relationship between carbon emissions in developed countries and non-renewable energy, and only one-way causality exists in developing countries.
