Hydroelectric and Tidal No polluting emissions in the air, no waste heat is rejected as thermal pollution

Pros: Dams can serve for multiple purposes water stored water stored for irrigation, flood control, municipal drinking water

Of the 180,000 mw potential in the US only 30% is developed, 70% more can be developed

The South American and African resources are 99% under developed

Hydroelectric facilities have life spans 50 to 200 years because of their storage volumes become filled with silt that is washed down stream by the rivers and fills the reservoirs.

SOLUTION: use streams overflowing rock bed so be could aim to use these to minimize this problem

The Bay of Fundy itself would be able itself to provide 15,000 mw and a similar amount to Canada

Estimated projection by 2000….Hydroelectric: 180,000 mw Wind: 46,000 OTEC-ocean thermal energy conservation: 25,000mw Geothermal: 20-60,000 Tidal 15,000

5.1-10 cents per kw/h nuclear 11-14 solar 15-30 c/kw/h. tidal 2-5cents kw/hr

Hydro is currently the only source of renewable energy making substantive contributions to global energy demand

Hydroelectricity eliminates the flue gas emissions from fossil fuel combustion, including pollutants such as sulfur dioxide, nitric oxide, carbon monoxide, dust, and mercury in the coal. Hydroelectricity also avoids the hazards of coal mining and the indirect health effects of coal emissions. Compared to nuclear power, hydroelectricity generates no nuclear waste, has none of the dangers associated with uranium mining, nor nuclear leaks. Unlike uranium, hydroelectricity is also a renewable energy source.
