Krisis energi fosil di Indonesia yang menyumbang 85% bauran energi nasional mendorong perlunya pemanfaatan sumber energi terbarukan, salah satunya exhaust wind sebagai energi limbah industri yang memiliki kecepatan tinggi (5-7 m/s) dan kontinuitas aliran yang baik. Penelitian ini mengembangkan turbin Savonius vertikal dengan variasi jarak exhaust-turbin (20, 30, 40 cm) dan kecepatan angin terukur (5.3, 6, 6.4 m/s) untuk mengoptimalkan pemanfaatan energi tersebut. Hasil penelitian menunjukkan bahwa konfigurasi 20 cm menghasilkan performa terbaik dengan daya maksimum 5.98 watt pada kecepatan 6.4 m/s dan Coefficient Performance (CP) 0.16, yang 31% lebih efisien dibandingkan jarak 40 cm, membuktikan potensi exhaust wind sebagai solusi energi terbarukan yang aplikatif di industri dengan payback period kurang dari 3 tahun dan potensi reduksi beban jaringan listrik hingga 15%.
