Energy security concerns, resource depletion, and environmental degradation have resulted from the world’s reliance on fossil fuels; this is an urgent research issue that needs resolution. As an alternative to fossil fuels, the key focus of this study was to assess the viability of an extensive combination of renewable energy sources such as solar, wind, and hydropower. The other objectives included assessing the current state of renewable technologies, identifying strategies to promote extensive adoption, analyzing integration challenges, and determining their capacity to meet global energy demands. The study was conducted using a descriptive technique and quantitative analysis. The study population comprised individuals with expertise in renewable energy, such as policymakers and industrialists. Ten individuals were selected using the purposive sampling method; five were industrialists, and five were policymakers. The data was gathered via surveys, and Excel was utilized to perform the statistical analysis. The research findings highlighted a clear trend of increasing consumption of renewable energy sources over the years, particularly evident within the European Union. This information provides policymakers with valuable evidence of the union’s dedication to sustainability. Developed nations and developing nations both demonstrated increasing trends in investment, suggesting growing international recognition of the renewable energy industry. However, the most striking pattern here is that younger people are much more knowledgeable about renewable energy technologies and more familiar with their effects, indicating that the future of adoption lies in the hands of generations to come. The study’s findings indicate that despite the presence of obstacles, there is an increasing impetus for the worldwide integration of renewable energy sources to address energy requirements and mitigate emissions. Prominent suggestions encompass mitigating obstacles to integration, establishing policies that provide support, funding ongoing research, and encouraging collaboration among stakeholders to facilitate the pivotal shift towards a sustainable energy environment.
