This study analyzes the integration of solar, wind, and hydropower systems across North America, Europe, Asia, and Africa, focusing on their performance, economic feasibility, environmental impact, and scalability. Solar energy contributed 40%, 50%, and 35% in North America, Europe, and Asia, respectively, while wind energy led in Asia at 45%. In Africa, solar energy contributed 40%, wind 30%, and hydropower 30%. Hydropower exhibited the highest efficiency rates at 85% across all regions, followed by wind (75%) and solar (60%). In Africa, the efficiency rates for solar, wind, and hydropower were 88%, 87%, and 91%, respectively. ANOVA results revealed significant regional differences in renewable energy performance (F = 5.21, p = 0.012), and regression analysis confirmed solar (β = 0.45), wind (β = 0.30), and hydropower (β = 0.25) as significant predictors of energy efficiency (R² = 0.82). Correlation analysis showed strong positive relationships between energy efficiency and solar (r = 0.85), wind (r = 0.80), and hydropower (r = 0.78). Carbon emissions were reduced by 3.2 million tons in North America, 2.5 million tons in Europe, 1.8 million tons in Asia, and 180,000 metric tons in Africa annually. Cost analysis revealed substantial long-term savings, with Levelized Costs of Energy (LCOE) for solar at $50/MWh, wind at $55/MWh, and hydropower at $45/MWh. In Africa, the initial investment for renewable energy systems was ₦900,000, with annual operating costs of ₦45,000 and total savings of ₦400,000 over five years. Scalability analysis indicated energy capacity growth rates of 10% in North America, 12% in Europe, 15% in Asia, and 14% in Africa. These findings emphasize the importance of region-specific strategies, hybrid energy systems, and technological advancements in enhancing the efficiency, reliability, and sustainability of renewable energy systems globally.
