1. Wind
Turbines!
A wind turbine is a device
that converts kinetic energy
from the wind into
electrical power.

2. Why do we need Wind Turbines?
• Wind power helps both combat climate
change and reduce reliance on fossil fuels.
Fun Fact!
Most wind energy comes from turbines that
can be as tall as a 20-story building and have
three 200-foot-long (60-meter-long) blades.
Smaller turbines erected in a backyard can
produce enough electricity for a single home
or small business.

3. Advantages:
• Wind energy is friendly to the surrounding environment, as no
fossil fuels are burnt to generate electricity from wind energy.
• Wind turbines take up less space than the average power
station.
• Newer technologies are making the extraction of wind energy
much more efficient.
• The wind is free, and we are able to cash in on this free source
of energy.
• Wind turbines are a great resource to generate energy in
remote locations, such as mountain communities and remote
countryside.
• Can you think of any more?

4. Disadvantages
• The main disadvantage regarding wind power is down to the
winds unreliability factor. In many areas, the winds strength is
too low to support a wind turbine.
• Wind turbines generally produce allot less electricity than the
average fossil fuelled power station, requiring multiple wind
turbines to be built in order to make an impact.
• Wind turbine construction can be very expensive and costly to
surrounding wildlife during the build process.
• NIMBYs – Not In My Back Yard! Many people don’t want the
countryside ruined by turbines or don’t want the noise
pollution that comes with them.
Fun Fact!
The slowly rotating blades can also kill birds and bats, but not nearly
as many as cars, power lines, and high-rise buildings do.

5. Poor Wind
Turbine!
People don’t
want me
around *sniff*
They said I look
ugly *sniff* >.<
Cheer up, it’s a
Fun Fact!
The wind energy
industry is booming.
Globally, generation
more than quadrupled
between 2000-2006. At
the end of last
year, global capacity
was over 70,000
megawatts! Wind
power is very popular
because it has a lot of
fans.

7. Quiz Time!
• Can you remember
like, anything, like, at all? Yeah, me too!
Let’s test that funky knowledge and get
down to the good stuff. Show off to all
your friends. Yes, it is I, victor of the
geography quiz! Your knowledge of
wind turbines is puny before mine!
Etc, etc.

8. Q1
• Why do we need Wind Turbines? At least 2
points please.

9. Q2
• Name Three advantages to Wind Turbines.

10. Q3
• Name Three disadvantages to Wind Turbines.

11. Q4
• Which 3 things kill birds and bats more than
wind turbines do?

12. Q5
• What was the global capacity for wind
turbines at the end of last year?

13. Q6
• How tall can wind turbines be?

14. Q7
• How many wind turbines do we need in order
to provide 20% of the UK energy demand?

15. 7 Questions!
• That’s right, 7 questions for the number of
blades you could find on three triple-bladed
turbines where one had been in a sad and
traumatic accident!
See?
Be happy I didn’t have a
question for every one of
the 231 wind farms in the
UK, okay?

18. Answers!
4. Cars, power lines, and high-rise buildings
5. Over 70,000 megawatts.
6. A 20-story building
7. 10,000 wind turbines. The same amount
of energy could be provided by 12 fossil
fuel power stations or 6 nuclear power
stations.
For those of you who got these last 3
incorrect, SHAME ON YOU. Pay attention
to my lovely Fun Facts!!!

19. What do people think about Wind
Turbines?
Olivia, self-proclaimed wind turbine
expert, said, ‘It’s that feeling when you drive
on holiday and you see a wind turbine and
it’s like, Oooooh! A wind Turbine!’
I was also going to include another opinion from
another equally valued expert such as Alison
Hill of the British Wind Energy Association but
then I decided that this expert point of view
was all we really needed to summarise this
personal and really quite complicated issue.

20. I thought it would be best to leave the
presentation there before I
descended into madness and started
spilling complete gibberish. How
considerate of me, I know.
I therefore leave you with this amazing
image I found online.
