Global climate change requires climate-friendly low carbon energy options. Hydropower is a low carbon energy sources which is globally abundant and has a high potential. Hydropower has been used around the world for centuries. In recent years, both small and large hydropower developments have seen increased use.
This project evaluates the global geographic and economic potential and the costs of both small and large hydropower, the greenhouse gas emissions from large hydropower reservoirs, the long-term implications of large hydropower projects (social, economic and environmental) and the opportunities and barriers for specific small hydropower turbines. The study draws on case studies from various countries, such as Brazil, China, Egypt, Lao, Norway, Pakistan, Thailand, Turkey, USA, Zambia/Zimbabwe.
