5.04 Hydroelectric and Wind Energy
Directions: Complete the following chart on hydroelectric and wind energy using the lesson.
Energy
Source
Is source always
available?
Advantage
Disadvantages
(at least 2)
How is the energy harnessed?
Hydropower
No
Hydropower does
not emit greenhouse
gases into the
atmosphere.
Dams can disrupt fish
migration.
Hydropower is dependent on
the water cycle.
By damming rivers to form large reservoirs or lakes.
Wind Energy
No
Wind energy does
not emit greenhouse
gases into the
atmosphere.
Wind turbines take up land
area.
The turbine blades can be
dangerous for birds and bats.
By wind turbines or windmills.
Directions:
Answer the following questions about hydroelectric and wind energy.
1.
In three to four sentences, describe how water is used to generate electricity and what energy conversions take place.
Water stored in a dam is a form of potential energy. When the water is released through the dam, it is converted to kinetic
energy. The moving water can then be converted to electrical energy within the hydroelectric power plant within the dam.
2.
List three factors that cause/create wind.
a.
Uneven heating of the atmosphere by the sun.
b.
Irregularities of the earth's surface.
c.
The rotation of the earth
3.
In two to three sentences, explain how wind energy is used to generate electricity.
Wind turbines are powered by the wind in the atmosphere. As the wind turbine blades turn, a generator within the turbine is
turned, converting the wind energy into electricity.
4.
Visit EPA Power Profiler linked on the task page to see what percentage of your power comes from hydropower, non-
hydropower, nuclear energy, coal, oil, and gas. When you get to this page, enter your zip code and click enter. Then choose
your electric utility company from the drop down box and click View Report. Scroll down and you can see the percentage of
your electricity that comes from each source by scrolling over the covered areas. Tell which source contributes the greatest
percentage of your power and describe how your area compares to the national breakdown.
Gas contributes the greatest percentage of my power with 51.5%. Compared to the national power percentage of 38.4%.
