This study investigates the dynamic, long-run relationship between renewable energy investments (REI) and economic growth (GDP) in Uzbekistan utilizing annual time-series data from 2005 to 2025. Employing the Autoregressive Distributed Lag (ARDL) bounds testing approach, the empirical framework estimates both short- and long-run elasticities while controlling for structural instability. The bounds test confirms a robust cointegrating vector between the variables, demonstrating that a 1% increase in renewable energy investments yields a 0.284% expansion in real output over the long term. Furthermore, the application of cumulative sum tests identifies a critical structural break in 2018, corresponding to institutional market liberalizations that amplified the capital multiplier effect within the domestic energy matrix. These findings offer empirical justification for the targets outlined in Uzbekistan's "Green Economy Strategy 2030" and Presidential Decree PF-60.
