What is hydropower?
Energy produced by moving or falling water.
100
Name the types of turbines.
The Pelton, the Kaplin and the Francis Turbine.
100
How much air pollution is produced and how is it produced?
Very little Static water increases rate at which organic material decays, causing carbon dioxide to be produced faster.
100
When did the Banqiao Dam collapse?
1975
200
Where and when was the first Hydroelectric Plant built?
Niagara Falls in 1881
200
Which rotates, the rotor or the stator?
Rotor
200
Name one method that is used to fix the fish migration problem with dams?
Fish ladders can be used.
200
What recreational activities can be done on a reservoir?
Canoeing, swimming, fishing, etc.
300
What are the two types of Hydroelectric Plants?
Fully manmade and partially manmade.
300
What is the energy transfer in a Hydroelectric Plant.
Gravitational --> Kinetic --> Mechanical --> Electrical
300
Under what circumstances will methane be produced from Hydroelectric plants?
If the organic matter decaying in the reservoir is in low oxygen water it will produce methane.
300
Name two initial damages after a collapse.
Collapse leads to flood which leads to: Settlements being destroyed, therefore, displacing people. People being swept away, harming or killing them.
400
For maximum energy production, what height of head is ideal for Hydroelectric Plants and why?
A high head, since it is raised higher it has more gravitational potential energy.
400
What are two factors in a Hydroelectric Plant's system that affect the amount of energy produced?
The amount of water intake and the velocity of the water.
400
How does a Hydroelectric Plant change the surrounding ecosystem?
It can turn a river ecosystem into a lake ecosystem. Its a barrier to fish and aquatic creatures. Clear cutting needed to build dam destroys forest habitats.
400
Are Hydroelectric Plants cost effective?
Depends, the initial cost and maintance cost are high, but can run for a long time.
