Abstract
This study examines hydropower's contribution to sustainable development through a
comparative analysis of international practices and national implementation strategies. A mixedmethods approach was employed, analyzing hydropower data from 45 countries over 2010-2023 and
conducting stakeholder interviews across five continents. Results indicate that hydropower accounts
for 16% of global electricity generation, with developing nations showing 68% higher growth rates
than developed countries. Norway leads in renewable energy integration (96% hydropower share),
while China dominates absolute capacity (370 GW). Environmental impact assessments reveal
significant variations in sustainability practices, with Scandinavian models demonstrating optimal
ecosystem balance. Economic analysis shows hydropower projects generate average returns of 8-12%
over 50-year lifecycles. The study identifies key success factors, including comprehensive
environmental planning, community engagement, and adaptive management frameworks for
maximizing sustainable development outcomes.
