2. Hydroelectric power is one method of creating
energy by using water.
Uses water starting in a reservoir, and ends
with the energy in the form of light in a light
bulb.
Hydroelectricity is generated in a hydroelectric
power plant.
3. The dam, lake, or
reservoir stores
water
The water goes
through the
Penstock to the
turbines

works.html#Converting_Moving_Water_to_Electricity
4. The turbine (propelled
by the force of the
water being carried in)
turns the generator to
produce the electricity
This electricity is then
sent through power
lines to produce
energy in the form of
light in a light bulb.

5. Dam, Lake, or Reservoir
Kinetic energy stays the same
Gravitational potential energy high
Dam holds water against the force of gravity
Penstock
Gravitational kinetic energy rises
Gravitational potential energy decreases
Turbine
Gravitational kinetic energy becomes kinetic energy of motion
Gravitational potential energy stays the same

6. Generator
Kinetic energy of motion rises
Potential energy rises
The water transitions to energy
Power Lines
Kinetic energy of motion rises
Potential energy decreases
Light Bulb
Kinetic energy of motion stays the same
Potential energy stays the same
Kinetic and potential energy have reached equilibrium

8. The largest
hydroelectric power
plants in the United
States are located in the
northwestern states of
the country
This is because they are
closer to the ocean
Providing more water to
be used in the process of
creating electricity
9. Is Hydroelectric Power a sustainable source of
electricity?
Yes it is!
Hydroelectric power is a renewable source which
produces little to no waste while creating electricity
10. Why is hydroelectric power not the main
source of electricity if it is sustainable and does
not produce much waste?
Is there any way that the amount of waste can be
reduced to no waste at all? How?
