Sample Answer 1
The first pie chart illustrates the average energy usage in a typical Australian family while the second pie chart shows the percentage of greenhouse gas emissions from this energy consumption. As is presented, water heating and heating & cooling consume the highest energy, producing the highest percentage of greenhouse gas in Australia.
According to the given data, water heating systems consume 23% of total energy consumption in an Australian household, while heating and cooling systems require 20% of energy. Refrigeration consumes 12% of energy which is larger than the energy required for cooking and lighting. Finally, 5% of energy is consumed in standby mode, and the remaining 24% is required for all other household appliances.
On the other hand, heating and cooling systems contribute to the highest percentage of greenhouse gas emissions which is 38%. Though they require more energy than heating and cooling, water heaters emit comparatively lesser greenhouse gas (25%). These two systems produce the highest percentage of greenhouse gas in Australia. Cooking, lighting and refrigeration generate 18% of total greenhouse gas, and all other appliances and standby modes generate 19% of such gas.
Sample Answer 2
The first pie chart compares the power consumption in a typical Australian house whereas the second one presents data on the percentages of greenhouse effects of these power-consuming equipment. As a general trend, the more energy a household appliance use, the more greenhouse gas it emits.
As can be seen, water heating, keeping the house warm or cool, consumes almost half of the energy required in an average Australian family. Cooking, standby and lighting utilise around 20% power, while refrigerators alone need 12% electricity. All other appliances consume the rest one-quarter energy share.
Interestingly, there is a correlation between the percentage of energy a particular device requires to run and the percentage of greenhouse gas this device produces, except for heating and cooling. Heating water, warming and cooling the rooms contribute to more than half of the total greenhouse gas emissions. Cooking, stand by and lighting combinedly contribute to 14% of gas production, which is almost the same as the amount produced by other appliances in a house.
In summary, heating and cooling devices emit the highest percentages of greenhouse gas though they consume less power than water heaters. Other devices contribute to dangerous gases based on the energy percentages required to function.
Sample Answer 3
The two pie charts represent the energy use in various segments of an Australian household and the resultant greenhouse gases as a by-product of that energy use in an unspecified period.
Heating and water heating accounted for the highest energy use in an Australian household, with 42% and 30% energy usage, respectively. Other segments like cooling, lighting and refrigeration’s combined energy utilization were more than one-tenth, whereas other appliances consumed 15% of energy.
Contrary to its energy consumption of less than a-fifth, other appliances produce nearly double the amount (28%) of greenhouse gases. Gas emissions by refrigeration and lighting also increased two-fold to 8% and 14% compared with their energy intake of 4% and 7%, respectively. Cooling, on the other hand, produces only 3% of greenhouse gas. Surprisingly, greenhouse gas emission by heating is significantly lower to 15% compared to its energy intake of more than two-fifths.
Overall, it is evident that heating and water heating accounted for significant energy use, whereas cooling, refrigeration, lighting and other appliances consumed less energy on average. However, the resultant greenhouse gases are given-off in large amounts by water heating and other appliances, while cooling, lighting, refrigeration, and heating produce lower amounts of gases.
Sample Answer 4
The first chart displays energy consumption in the average household in Australia, while the second chart illustrates the greenhouse gas emissions that come from this energy consumption.
Overall, while heating and water heating account for a significant proportion of energy use, most greenhouse gas emissions result from watering heating and other appliances.
Heating and water heating are the two most significant energy uses, at 42 and 30 percent of the total, respectively. Other appliances consume another 15 percent, which is roughly twice as high as the percentage of energy used for refrigeration. The proportions of energy consumed for lighting and cooling are both tiny, at 4 and 2 percent respectively.
Water heating is also a major source of greenhouse gas emissions, making up almost a third of total emissions. The second-largest amount of emissions come from other appliances, at 28 percent of the total. Heating, surprisingly, is only responsible for 15 percent of total emissions, and this figure is roughly the same as that for refrigeration. The remaining 11 percent results from lighting and cooling.
Sample Answer 5
The first pie chart illustrates the average usage of energy in housing in Australia. while the other provides information about greenhouse gas emission due to such energy consumption.
Overall, a significant majority of energy was consumed for heating in contrast with a trivial amount of it was used up for cooling purposes. Nevertheless, most of the harmful gases were emitted by heating water.
With regards to the usage of energy, heating took around 42% of energy, while water heating consumed just under one-third of the total energy. Cooling consumed the least energy, just 2 % which was half of the amount used for lighting. Refrigeration consumption was about 7% and the remaining contributed to other appliances.
Water heating, which was dominant in liberating greenhouse gas, released around 32%, approximately double the emission from refrigeration and heating. Cooling contributed to a minor proportion of emissions (about 3%), almost 5% less than that from lighting. The left out 28% came from other appliances.
Sample Answer 6
These two pie charts show information about household energy use in Australia and the resulting greenhouse emissions. While heating is the greatest use of energy, it is not the most significant producer of greenhouse gases. Greenhouse gases are produced by water heating more than any other source.
The first pie chart displays energy use in the average Australian house. Here, heating requires the most energy, at 42% of the total, followed by water heating at a little over a third. The smallest fraction is cooling at just 2% of the total energy use.
While heating uses 42% of the total energy, it only causes 15% of the total greenhouse gases. However, water heating is more or less proportional to its total use, producing a little less than a third of the greenhouse gases emitted by the average household. Refrigeration produces 14% of the total emissions, despite only using 7% of the house’s energy.
Sample Answer 7
The two pie charts describe the energy used by an average Australian household and greenhouse gas emissions from energy use. The first pie chart compares the power consumption of electronic appliances in a typical Australian house. In contrast, the second one shows data on these power-consuming appliances’ percentages of greenhouse effects. As observed, the more energy a household appliance consumes, the more greenhouse gas it emits.
As can be observed, water heating and keeping the house warm or cool consumes most of the energy required in an average Australian family, with 23% and 20%, respectively. Cooking utilises 5%, standby 5% and lighting 11%, with total utilisation of 21% of the power, while refrigerators need 12% electricity. All other appliances consume the rest 24% of the energy share.
Interestingly, the percentage of energy a particular appliance requires to run and the percentage of greenhouse gas this device produces is directly proportional except for heating and cooling device. Heating water produces 25% of greenhouse gases, and warming and cooling the rooms contributes 38%, with more than half of the total greenhouse gas emission.
Cooking, stand by and lighting combinedly contribute to 14% of gas production, which is almost the same as the amount produced by other appliances in a house.
Sample Answer 8
The two pie charts represent the energy use by an average Australian household and the emission of greenhouse gas as a by-product of this energy use.
At a glance, it is clear that the highest energy consumption is because of heating, whereas the highest greenhouse gas emission is due to the usage of water heating appliances.
At 42%, heating makes up the most significant proportion of household energy consumption, but its effect on greenhouse gas emission is only 15%; this is almost half of the emission rate caused by water heating which amounts to 32%. However, using other appliances is only 15% of the total energy, but its corresponding greenhouse gas emission is almost twice that of that source, i.e., 28%.
Moreover, it is prominent that although refrigerators and lighting use comparatively less energy – 7% and 4% respectively- they cause double the gas emission each. Furthermore, except for cooling, which uses the least energy of all, all the other appliances contribute to emitting significant amounts of dangerous gases based on the ratio of energy they require.
Sample Answer 9
The first pie chart gives information about the proportions of energy consumption in an average Australian household. Accordingly, the second pie chart illustrates the percentages of greenhouse gas produced by energy uses.
Overall, most of the energy in an average household in Australia is used for heating, but most greenhouse gas emissions come from water heating and household appliances. The amounts of greenhouse gas generated from refrigeration and other appliances are approximately twice as high as their percentage of energy consumption.
It is clear from the charts that heating makes up the most significant proportion of household energy use in Australia, with 42%, as opposed to only 15% of greenhouse gas produced by this usage. In contrast, almost a third of the energy consumed by an Australian household is used for water heating (30%). There is a similar figure for greenhouse gas emitted by this usage (32%). The figures for other appliances and refrigeration uses have the same tendency, in which the quantities of greenhouse gas generated (28% and 14% respectively) are around twice as much as the amounts of energy used (15% and 7% respectively).
Only a tiny minority of energy is used for cooling and lighting, accounting for 2% and 4%, respectively. These two usages also constitute the two lowest proportions of greenhouse gas emissions, with 3% and 8% in the same order as mentioned.
Sample Answer 10
The pie charts compare the percentages of energy consumed for various purposes and how much an average Australian family emits greenhouse gas.
Overall, heating accounts for the highest energy consumption, yet the most significant proportion of CO2 emitted belongs to water heating.
42% of the energy consumed in an Australian family is used for heating, the highest figure on the chart, followed by water heating, at approximately 30%. In contrast, the figure for other appliances makes up merely 15%, and the rest, including refrigeration, cooling, and lighting, occupy trivial proportions, under 7% each.
Regarding greenhouse gas released, water heating and other appliances are the major causes, with about 32% and 28% respectively. In comparison, the data for heating and refrigeration are lower, standing at about 15% each. Both cooling and lighting are responsible for producing one-tenth of total gas emissions.
