This study explores the energy efficiency, renewable energy, and economic growth nexus on CO2 emissions in the MINT countries of Mexico, Indonesia, Nigeria, and Turkey from 1990-2023. Despite the significance of energy efficiency in environmental policy formulation, the heavy reliance on fossil energy in these countries has led to significant environmental challenges due to climate change concerns. Previous studies have predominantly used the symmetric model, arguing for a linear nexus and neglecting possible asymmetric contributions between renewable and nuclear energy on economic growth and urbanization as CO2 emission stimulators. This study adopted the asymmetric panel non-linear autoregressive distributed lag (PNARDL) to argue for asymmetric nexus. The key findings revealed an asymmetric nexus indicating that green energy sources reduce CO2 emissions and improve ecological quality through energy efficiency and renewable energy. The economic growth and CO2 emission nexus support the Environmental Kuznets Curve (EKC) hypothesis, indicating that ecological quality reprobates during the early phase of economic growth and improves as the economy evolves to prioritise environmental quality. The negative nexus between nuclear energy and CO2 emissions highlights a deficiency in nuclear energy generation to mitigate CO2 emissions effectively. Based on these findings, the study recommends prioritizing renewable energy policies, streamlining the regulatory approval process for nuclear energy projects, and providing incentives for investment in the nuclear power infrastructure to achieve the 2030 Sustainable Development Goals (SDGs) for environmental quality and sustainability.

In Iran, due to the problems and constraints of fossil fuels and the need to maximize the use of solar potential, one of the best ways is the application of photovoltaic systems integrated with buildings. Due to the significant dependence of solar cell performance on the availability of radiation, it is necessary for architects to have an accurate assessment of the amount of electricity produced in different conditions. Therefore, in the present work, using HOMER software, the energy-econo-Enviro (3E) potential of a Building Integrated Photovoltaic (BIPV) in Abadan was studied. The effect of slope and azimuth of solar cells as well as cloudiness and system losses were investigated using sensitivity analysis. The results showed that the PV-grid system was the most economical option and after the azimuth angle of zero degree, the positive azimuth angle was the most economical. The results also showed that the slope of 30 degree and the angle of azimuth equal to zero was appropriate, for which the price per kWh of generated electricity was calculated to be $0.09. For the use of solar cells in the vertical wall of the building, the southwest direction was the most suitable and based on the results, it was suggested that the western wall of the building should be in the form of “inclined PVs with windows”. The authors of this paper hope that the results of the present work can be used by architects and energy decision-makers as a guide in developing the BIPV use in Iran.
