A Year 12 student from Hawkesdale P12 College produced this slideshow as school assessed coursework for Unit 3 VCE Environmental Science.

3. Wind energy
(Non fossil and renewable)
Gas energy
(Fossil fuel and Non
renewable)
What is it?
• Wind energy is a non
fossil fuel
• It is created with the
wind turbines which are
basically really large fans
• It is a clean energy
source
• Gas fuel is a fossil fuel
• Once it is used it can not
be salvage for reuse
Where do you
find this energy
source?
• All wind energy in the
world comes from wind
turbines, there are over
225,000 turbines that
are operating wide
spread over 75
countries.
• Natural gas is extracted
from two different
locations, way under the
sea bed and also deep
underground. Mortlake
power plant collects its
gas from a dedicated
83Km wide spread
underground gas
transmission pipeline

4. Wind energy
(Non fossil and renewable)
Gas energy
(Fossil fuel and Non
renewable)
How does it
work?
• Air and gas mix together causing
a combustion within the turbine
• The force of the combustion
causes the rotors in the turbine to
spin
• The turbine is then coupled into a
generator
• The turbine is then coupled to a
generator
• As the turbine spins, the
generator rotates and produces
electricity
• Electricity from the generator is
passed through a transformer and
uploaded to the grid
• Wind causes the blades to
spin
• This causes a shaft to spin and
connected to the shaft there
are a set of magnets and
copper wire
• When they start spinning on
the shaft this causes the
generator to react in the same
way and when it starts to spin
it generates electricity

(Fossil fuel and Non

Transportation
• Connected to the
Mortlake gas plant there
is a dedicated 83 Km
Underground natural gas
transmission pipeline,
most gas plants use this
method because it is an
easy and effective way of
transferring the point of
origin to the location with
the highest gas energy
demands when ever it is
needed.
• Wind energy can not be
transported
• Although wind energy it
self can not be
transported the parts
had to be transported
to the wind farm area,
parts came from places
such a Denmark just to
get all the way to
Macarthur.

6. Usage

7. Worldwide installed wind capacity

8. Wind energy

Gas energy
(Fossil fuel and Non
renewable)
Why the location
and How is it been
affecting the land?
• The land of the Mortlake gas
comes to a total of 100
Hectares which is owned by
origins, there is 20 Hectares
which is used by the actual
gas plant that consists of the
facilities, roads for people to
navigate there way around
the gas plant, security fences
and the pipeline system. The
other 80 Hectares are
dedicated to farm life such as
cattle and sheep for grazing.
They will soon be
constructing more facilities
that push
• The Macarthur wind farm is
put across three different
properties which were
previously used for the
grazing of sheep and cattle
• The area across the 3 different
properties comes to a total of
5,500 hectors
• The wind farm is placed in an
area of which there is a
considerable amount of wind

Gas energy
(Fossil fuel and Non

What advantages or
disadvantages are
there for each
energy source?
Pros
- Natural gas energy can be
switched on and off
whenever you want in the
matter of 6 minutes
- It is near instant energy
source, it can be accessed
and used in minimum 6
minutes
Pros
- It is highly renewable
- Once it is up and running it
uses no green house gases
- Wind turbines are duel use
Cons
- CO2 is put into the
Atmosphere causing
greenhouse gas
- It is highly explosive
- Using gas energy can be
quite expensive
Cons
- During construction
There was a large amount
of green house gases was
released into the
atmosphere
- It is Unreliable due to the
fact that you don’t know
when it will be windy
- People of the community
often complain about the
wind turbines and the
“Harm” they are doing.

Green house gas
effect
• During the burning of gas there is
quite a substantial amount of CO2
is released into the atmosphere
• During construction there was
a lot of green house gases
released into the atmosphere
but what damage they did to
the earth and the Ozone layer
they repaid after 6 months of
clean energy once the wind
farm was up and running

11. Kyoto Protocol
• The Kyoto Protocol treaty was something that was created in
December 1997 in a city in Japan called Kyoto and came into force
February 16th, 2005.
• The Kyoto Protocol is a legally binding agreement under which
industrialized countries will reduce their collective emissions of
greenhouse gases by 5.2% compared to the year 1990 (but note
that, compared to the emissions levels that would be expected by
2010 without the Protocol, this target represents a 29% cut). The
goal is to lower overall emissions from six greenhouse gases -
carbon dioxide, methane, nitrous oxide, sulphur hexafluoride, HFCs,
and PFCs - calculated as an average over the five-year period of
2008-12. National targets range from 8% reductions for the
European Union and some others to 7% for the US, 6% for Japan,
0% for Russia, and permitted increases of 8% for Australia and 10%
for Iceland.

12. Social/economical/Environmental Impact
Competitors Points
Wind Energy • Wind farms can cost billions of dollars, the Macarthur wind farm came
to a total of $1,000,000,000
• During the construction there was a lot of green house gases emitted
but what damage they had done during construction of the Macarthur
wind farm they paid back in 6 months of energy saving wind power
• During the construction of the Macarthur wind farm there was a large
amount of damage done to the roads
• Farmers with a turbine/s on there property receive $12,000 a year per
turbine as compensation
• Wind turbines do not have the best reputation in everyone's eyes,
there are myths such as that they cause head aches, they can kill birds
in the area, they affect farmers cattle and that having turbines on
someone's property can affect there real estate value, but again they
are still just rumours and myths
• Wind turbines have been known to be noisy for people close to them
• Wind farms are often involved in community funds
Natural Gas energy • Origin gas is the only one who earns a profit from there line of work
• The Mortlake Gas plant has a high reading of green house gas that it
emits CO2
• During the construction of the Mortlake gas plant all the constructers
and engineers stayed in local motels which means the community was
earning a profit

13. And the winner is……..

14. Evaluation
• In conclusion to my presentation and after we have
studied all this facts and statistics it is hard to say the
wind power isn’t the superior energy source. Not only
is it a clean and renewable energy source but it is a lot
better for planet earth and it is also a lot cheaper to
run once constructed. AGL would also have the be the
superior competitor in the energy company brawl due
to the fact that they seem a lot more community
friendly the way they get involved with local things
such as schools and cricket clubs but they also make
generous donation to local community groups.
