Abstract
The increase in greenhouse gas emissions is one of the crises in today's world. Because it doubles global warming and environmental pollution. The increase in greenhouse gas emissions has encouraged many countries to substitute renewable energy instead of fossil fuel. The effective use of green energy such as renewable energy and nuclear energy is highly dependent on the technology used in the production of this type of energy. For this reason, the aim of this study is to investigate the impact of importing information and communication technology goods on renewable energy production in Iran. In this research, has been used the Computable general equilibrium model based on the social accounting matrix of 2014. The results show that in all scenarios, the production of fossil electricity in both peak and base times, as well as the production of ICT goods, will decrease because with the release of the import of these goods, foreign ICT goods will replace domestic ones and the production of these goods will be domestic. Also, the production of other sectors has increased and the largest increase is related to the gas sector. By applying the first scenario (10 to 100% change in tariff, without change in the productivity of production factors related to the production of renewable energies), with the further reduction of the tariff, the production of renewable electricity will also decrease in both peak and base times, but when The fact that the import of ICT goods is accompanied by a 3, 5 and 7 percent increase in the productivity of the production factors related to the production of renewable energies (scenarios two to four) will increase the production of renewable electricity in the base load. The production of renewable electricity at peak load has decreased in all scenarios and the results do not change with the increase in efficiency. By reducing the tariff on the import of ICT goods, the amount of CO2 emissions will decrease. Also, as the productivity of the production factors related to the sector of renewable energy production increases, CO2 decreases to a greater extent. It should be noted that with the reduction of the tariff on the import of ICT goods, the price of the goods has decreased in the investigated sectors. As a result, reduce the pollution caused by the consumption of fossil fuels and use them optimally.

Abstract
Promoting electricity generation from renewable energy sources has emerged as a cornerstone of sustainable development strategies worldwide to mitigate greenhouse gas emissions and address the pressing challenges of climate change. This study aims to investigate the nonlinear relationship between the Productive Capacity Index (PCI) and renewable electricity generation across a sample of selected developing countries during the period 2000–2022. To this end, the dynamic panel threshold model proposed by Kremer et al. (2013) is utilized, as it enables the analysis of nonlinear interactions among variables in panel data while addressing potential endogeneity. Our findings reveal a non-linear relationship between PCI and renewable electricity generation. Importantly, the influence of PCI on the share of electricity generated from renewable sources intensifies beyond a specific threshold value. This implies that as PCI levels increase, their impact on clean energy production becomes more significant, emphasizing the importance of advancing productive capacities to accelerate the transition to renewable energy. Furthermore, the results underscore the critical role of several key factors in enhancing renewable electricity generation. Rising geopolitical risks, improved financial development, greater trade openness, and an increased share of gross fixed capital formation in GDP are identified as pivotal drivers that positively contribute to the expansion of renewable electricity generation. Conversely, weak environmental policies can significantly hinder this progress. Furthermore, the Dumitrescu and Hurlin (2012) panel causality test confirms the existence of a bidirectional causal relationship between the share of renewable electricity generation and the other explanatory variables. This study highlights the critical need to build and strengthen productive capacity to support the growth of renewable energy. The findings provide a valuable foundation for informed decision-making by policymakers and planners in developing nations.
