GRAPH NO. 10
The line graph shows the consumption of renewable energy in Australia from 1975-2000.
Renewable Energy Total Consumption and Major Sources, 1975-2000.
Write a 150-word report identifying the main trends and making comparisons where relevant.
The line graph shows growth in the consumption of renewable energy during the period 1975-
2000 in Australia. The results are also broken down by source.
The first thing to note is that the use of renewable energy has doubled over the period, with
particularly strong growth in biofuels. This sector did not exist in 1990, but experienced a
steep rise during the 2000s to over one quadrillion per year. This made biofuels a serious
challenger to both wood and hydroelectric power, which both saw only a limited overall
growth. The former grew steadily between 1985 and 1990, but then slipped back to around its
original level of 1.8 quadrillion Btu. The later began the period at the same level as wood, but
experienced more substantial growth. However, it also fell back to around 2 quadrillion Btu,
with a particularly sharp drop in the late 1995.
Finally, wind power emerged late in the period but showed a gradual rise to around 0. 5
quadrillion Btu, suggesting that it, along with other biofuels, will replace wood and
hydroelectricity as the main sources of renewable energy in the future.

GRAPH NO. 11
The diagram below illustrates the Carbon Cycle in nature.
Write a 150-word description of this diagram for the university lecturer.
The diagram shows how carbon moves through various stages to form a complete cycle. This
report will give a brief description of the main stages in this cycle.
First, we can see that energy from the sun is transformed into organic carbon through a
process in plants known as photosynthesis. This organic carbon is then transferred
underground when plants and animals that feed on them, die and decay. Some of this carbon is
trapped underground in the form of fossils and fossil fuels.
Carbon is also released back into the atmosphere, however, through various means. One is
when animals and plants respire, and another is when humans burn fossil fuels in cars
andfactories. All this carbon enters the atmosphere as CO2. It is then reabsorbed by plants
and the cycle begins again.
Overall, we can see that carbon moves in a natural cycle, although human factors may now be
affecting the balance.
