Digital Artefact 1 - Tiny Home Environmental Design
Gas versus Wind as an Energy Source - Nick
1. Unit 3 Environmental Science:
School Assessed Coursework for Area of Study 1
SAC 1B: A report in multimedia format
“Describe the principles of energy and relate them
to the contribution of one fossil fuel and one non-
fossil energy source to the enhanced greenhouse
effect.”
2. quick comparison
Mortlake Gas-Fired Power Plant
Fossil fuel
100 hectare total land
20 hectare site
550 Mega Watt capacity
$650 million
Peak load
Reliable – 6 minutes to turn on
Gas fuelled power
plants cover 20% of
Australia’s electricity
generation
Macarthur Wind Farm
Non fossil
10,000 hectare site
3 farms (dual use)
420 Mega Watt capacity
$1.4 billion
Base load
Unreliable – not always wind
Wind energy sources generate
2% of Australia’s electricity
3. introduction to gas & wind
gas energy
Gas is a fossil fuel, non-renewable
energy source.
Natural gas is formed as a result
of the combustion of
decomposed plants and animals
buried under layers of rock and
soil for millions of years.
Natural gas is found underground
in oil reserves.
wind energy
Wind is a non-fossil, renewable
energy source.
Wind is formed when sunlight falls
unevenly on the earth, heating
the air unevenly. The circulation
of the warm air rising and cool air
moving in to replace it, produces
wind.
Wind energy has
become more
and more
widespread over
the past 18 years.
4. extraction
gas
Origin Energy uses offshore
platforms to extract raw gas
from the two offshore gas
fields, Geographe and
Thylacine, located 55km &
70km south of Port Campbell.
5. transport
gas
After being extracted
offshore, gas is transported
through offshore and
onshore pipelines to the
Otway gas processing
plant. From there the gas is
piped to the Mortlake gas-
fired power plant.
The electricity produced
travels through large pipes
to a transformer and then
high voltage power lines.
wind
Turbine parts
transported by boat
and trucks
The electricity produced
is transported through
underground cables to
the substation. The
voltage is stepped up
and then the electricity
enters the high voltage
power lines.
This is the Tarrone
Substation, part of the
Macarthur Wind Farm
6. use
gas wind
Wind is used to generate
electricity
Wind turns the turbine blades
which turn a low speed shaft
The low speed shaft enters the
gearbox which connects to
the high speed shaft
The high speed shaft enters the
generator
The generator rotates and
produces electricity
Gas can be used for heating,
cooking or generating electricity.
The use of natural gas to generate
electricity is similar to the engine of
a car.
Air and gas are mixed together and
combusted within the turbine
This force causes the rotor of the
turbine to turn
A shaft connects the turbine to the
generator
The generator rotates and
produces electricity
7. economic impacts
gas
The Mortlake Gas-fired
Power Station cost
$650 million to
construct
The construction
created jobs, there are
10 staff altogether but
only 6 are required if
only one turbine is
turned on and
generating electricity
wind
AGL Macarthur Wind Farm
Community Fund Program
provides financial assistance to
community projects and
groups.
$5000 per turbine per year is
payed to the farmers that
have turbines on their land.
The Macarthur Wind Farm cost
$1.4 billion to construct
The construction created 400
jobs (250 for locals), there are
20 local staff currently on site
Other main costs include spare
parts and council rates
8. social impacts
gas
Origins commitment:
“Origin respects the rights
and interests of the
communities in which we
operate by working safely
and being mindful of, and
attentive to, the
environmental and social
impact of the resources,
products and services we
use or provide to others.”
People in the area do not
enjoy the look of the power
station
wind
Citizens that live near the wind
farm complain that the
turbines make a noise and that
they have become ill because
of the turbines, it has been
proved that this is a result of
anxiety and that the turbines
are not at fault.
Some people do not like the
look of the structures on the
wind farm
The Macarthur Wind Farm are
always happy to have school
students or visitors to take a
tour of the wind farm
9. environmental impacts
gas
The Mortlake Gas-Fired Power Station
takes up a 20 hectare site, but own the
100 hectare block of land around the site.
Origin have considered planning the
construction of another two gas turbines,
but other than that the remaining land is
being wasted
The Mortlake plant has been built on land
which native animals such as Emus and
Kangaroos are often seen and Origin have
done nothing to recreate more habitats
for them after taking away their home.
The combustion of natural gas emits
greenhouse gases such as carbon dioxide
and water vapour which contributes to
the enhanced greenhouse effect
Natural Gas is a fossil fuel and is being
used in much larger amounts than how
much is being produced
wind
The Macarthur Wind Farm
takes up 10,00 hectares, but
the land is dual use so the
landholders can continue to
run livestock.
Before construction, AGL
employed environmentalists to
observe the land to certify that
the proposed sites of the wind
towers did not obstruct native
animals habitats.
Animals can be effected by
wind farms. For example, birds
can fly into the turbine blades
and die.
The use of machinery during
construction emitted
greenhouse gases.
10. greenhouse effect
natural
Heat energy from the sun beams
onto the earth, some of it passes
through a blanket of gases in our
atmosphere and some is absorbed
by the blanket of gases.
This blanket of gases is made up of
greenhouse gases, without this
blanket all the heat energy would
escape and the average
temperature of the earth would be
-18°C
Natural greenhouse gases are
carbon dioxide, water
vapour, methane, sulfur dioxide
and nitrous oxides
enhanced
Human activities including
the burning of fossil fuels
(gas) are creating more
greenhouse gases, which
means more heat energy is
absorbed and the earth
gets hotter.
Man-made or unnatural
greenhouse gases are
hydrofluorocarbons (HFC’s)
and chlorofluorocarbons
(CFC’s)
11.
12. contribution to the
greenhouse effect
gas
Gas contributes to
the enhanced
greenhouse effect
by burning natural
gas and emitting
greenhouse gases.
wind
Wind farms only
contribute to the
greenhouse effect
during construction.
Wind farms are very
clean and a
sustainable source of
energy.
