Renewable energy plays an essential role in diminishing carbon emissions, which can be harmful to climate change and pose a threat to our lives. Therefore, this study has the main objective of examining the nexus of renewable energy consumption, trade openness, and climate change. The data used is panel data for emerging Asian countries in the period of 2010-2021. The Granger Causality Test and The Vector Error Autoregressive Model were employed to investigate the relationship among variables. The findings indicate a unidirectional relationship between renewable energy and inflation, and renewable energy consumption and CO2 emissions. The findings suggest carbon dioxide emissions can drive renewable energy consumption. It provides a signal that low carbon development benefits from globalization and that globalization stimulates renewable energy growth and helps to cope the climate change. The research results also confirm that there is a bidirectional relationship between trade openness and inflation. The impulse response analysis supports the notion that there is a robust negative correlation between a country’s trade openness and its inflation rate, both in the short and long term.

As a result of growing energy demand, shortage of fossil fuel resources, climate change, and environmental protection, the need for renewable energy sources has been growing rapidly. However, there is an urgent need to cope with intermittency and fluctuation of renewable energies. Various energy storage systems are considered as appropriate solutions to the above-mentioned problem. In the present manuscript, a novel compressed carbon dioxide energy storage system was proposed. Furthermore, an extra thermal energy storage with Therminol VP-1 as a working fluid, coupled with Parabolic Trough Collector (PTC), was added to the system. This integration is conducive to rising the inlet temperature of turbines and reducing the work load that should be done by the compressors. In the present study, a method based on software product including Engineering Equation Solver (EES) for determining thermodynamic characters per component and System Advisor Model (SAM) was employed to model the solar field for a desired location. Energy and exergy analyses were conducted to evaluate the whole cycle performance during charging and discharging periods. In this study, the city of Kerman located in the south-eastern part of Iran, with Direct Normal Incidence (DNI) of 950 , was selected for the present modeling. The results of a random day (June 22/2019) at time 15:00 represented the exergy efficiency of 66.98 % and the round trip efficiency of 93.14 %. High exergy efficiency and round trip efficiency of this system make this idea applicable to enhancing the total performance of the entire system.
