HYDROELECTRIC ENERGY

Structure & Function

Advantage of Hydroelectric Energy1. Not dependent on fossil fuel such as oil,

natural gas, and coal.

2. Hydroelectric generators have longer functional life than fuel fired generators.

3. Renewable - dependent on the continuous water cycle.

4. Reduced carbon emissions.

5. Global accessibility.

6. Low operation and maintenance costs.

1. They disturb natural flow of rivers.2. Create holes beneath the dam where the

water falls.3. Smaller modules depend on the fast flowing

rivers. 4. Can impact the mobility of fish and other

wild life. 5. High investment costs6. Changes in water quality

Disadvantages

The Future of Hydroelectricity in the United States

I believe the U.S. will create more hydroelectricity dams because the U.S. wants to become less dependent on foreign oil and less oil drilling means fewer oil spills.

THE FUTURE OF HYDROELECTRICITY AROUND THE

WORLDI believe that the world will become more hydroelectric dependent.World hydroelectricity production progressed, in the 10 years between 1995 and 2005, by 18%.
