Energy poverty affects 2.6 billion people globally, with rural communities disproportionately impacted by lack of reliable electricity access. This research presents a comprehensive framework for designing and implementing renewable energy microgrids tailored to rural community needs. We developed optimization algorithms for solar-wind-battery systems and tested prototype implementations in three rural locations across Argentina, Qatar, and Kenya. Economic analysis demonstrates payback periods of 4-6 years while providing 99.7% system reliability. The study includes detailed technical specifications and community engagement strategies for successful microgrid deployment.
