The increasing reliance on renewable energy sources has become a global necessity to address climate change and meet the growing energy demand. Among these, wind and solar energy play a crucial role due to their sustainability and environmental benefits. However, the inherent intermittency of these sources poses significant challenges in ensuring a stable and reliable energy supply. This study investigates the optimization of spatial allocation for wind and solar power generation, utilizing Modern Portfolio Theory (MPT) as a framework to enhance efficiency and mitigate risk. By analyzing production patterns, capacity factors, and risk diversification strategies, this research provides insights into optimizing resource allocation for investors, policymakers, and grid operators. The findings contribute to advancing a resilient and sustainable energy infrastructure.
