Hydroelectric Power

What is hydroelectric power?

the power created by the movement of water

how is hydroelectric power created?

As the water falls from the sky, the water is moved through a turbine creating energy.

What are the major systems?

Run-of-the-river, Tidal and Water impoundment (Damps)

What are the advantages of hydroelectric power?

CO2 emmissions, Flood control, recreation

What are the disadvantages of hydroelectric power?

siltation, limited access, and disrupts the flow (fish)

Run of the river

• The water running through creates energy
• saves the siltation problem
• Only can create energy with movement

Water impoundment

• huge wall with a reservoir behind it, the water let through creates kinetic energy from potential energy

Tidal system

• the water is moved back and forth as the tides come in and out
• \

advantages of hydroelectric energy

• renewable energy
• irrigation
• flood control
• recreation
• reduces CO2

disadvantages of hydroelectric energy

• expensive
• destruction
• siltation
• fish spawning
• limited
