Hydropower’s Contribution to Sustainable development
• What is Sustainable Development
• It is an economic development without polluting environment:
• economic development maintained within acceptable levels of global resource depletion and environmental pollution.
• Benefits of Hydropower developments.
• It is renewable source of Energy;
• It self is a source of Clean, renewable, reliable and affordable Electricity.
EAPIC 2008, 16-18 September, Nairobi, Kenya
Hydropower’s Contribution to Sustainable development
• Supports the development of other renewable energies.
• If well planned, developed & managed it provides;
• Quality of life (Leisure & Tourism)
• Transport facility (water way).
• Agricultural development (Irrigation)
• Safety (Flood protection)
• Health (Fresh water Storage)
• Education (Research center)
EAPIC 2008, 16-18 September, Nairobi, Kenya
Contd… sustainable ..
• Pease (Regional Stability)
• Power system stability and Reliability
• Creates price stability (It is Indigenous)
• Can reduce pollution and help fighting climate change.
• It is Flexible, available & sustainable.
“With good planning and management, hydropower is, therefore, a catalyst for sustainable improvement of people’s lives”.
EAPIC 2008, 16-18 September, Nairobi, Kenya
Contd…sustainable…
• It means that also, by doing so, we contribute & take part in the fulfillment of “UN’s Millennium Development Target”.
• Not only to think developing this sector but supporting those developing it is, therefore, highly important & necessary.

World’s Hydropower
Facts on global hydropower developments;
• Globally, hydropower recourses are still underdeveloped.
• Africa is the least, developed only 7% of its potentially to be developed.
• Hydropower supplies one-fifth of the worlds electricity.
• Only one–third of the world’s Potential Hydropower has been developed.
• Hydropower supplies 92% of electricity from renewable sources……
EAPIC 2008, 16-18 September, Nairobi, Kenya
Contd…World’s Hydropower
Highlights on World’s Largest Producer of Electricity.
• Developing a culture of being updated on what has been done and is being done globally helps to understand where we are.
• Our status (where are we?)
�Information in this regard (Top 9);
�Three Gorges, China, 22,400 mW
�Itaipu, Brazil, 14,000 mW
�Guri, Venezuela, 10,000 mW
�Tucurui, Brazil, 8,365 mW
