Evaluating the role of renewable energy and smart city technologies in mitigating the impacts of climate change

This paper will discuss how the issue of renewable energy and smart city technologies can be used to reduce the effects of climate change, and how their diffusion influences the environmental sustainability and resiliency of the city. Data were gathered using quantitative research design in which structured surveys were conducted on energy experts, urban planners, environmental officers, ICT professionals and policymakers in selected cities. They were analytical techniques, such as descriptive statistics, correlation analysis, multiple regression, ANOVA, the variance inflation factor (VIF) tests, and the normality tests, structural equation modelling (SEM) to evaluate the relationship between renewable energy adoption and innovative city technologies and climate change mitigation outcomes.  
The results have shown that renewable energy technologies especially solar, wind, bioenergy, contribute to a high level of decrease in greenhouse gas emissions and improve the environmental performance. Such new city elements as smart grids, IoT-related monitoring, smart mobility, and automated energy management systems also play an important role in enhancing energy efficiency and minimizing carbon footprints. The SEM findings show that the integration of renewable energy and smart city technologies has a synergistic outcome, which creates more effective climate mitigation results than implementing either of the two strategies. The quality of governance, socioeconomic elements, and policy support were observed to mediate the success of these technologies in a significant manner.  
The paper finds that the adoption of renewable energy frameworks as a part of new urban development is a very potent avenue towards the realization of climate resiliency and sustainable city building. It advises to enhance institutional structures, invest in climate technologies more, and encourage collaboration between the public and the private to achieve the maximum benefits of climate mitigation. The study has a contribution to the literature as it provides empirical evidence and a multidimensional analytical framework that would bridge renewable energy, smart cities, and mitigation of climate change.
