Sample Essay
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 largest uses of energy, 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 very small, 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 comes 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.

How To Vary Your Language
Greenhouse Gas Emissions
“Greenhouse gas emissions” is a common and well-recognized phrase. Don’t try to change it. For example, don’t change it to “the amount of greenhouse gases emitted/produced”. One way is to use just “emissions”. Once we’ve established the context that we’re talking about greenhouse gas emissions, ‘greenhouse gas’ becomes redundant, as it’s obvious we’re referring to that. Please read the last paragraph to see how I used only “emissions”.
We can also use the constructions below to vary our language:
- Most emissions result from watering heating and other appliances.
- Most emissions come from watering heating and other appliances.
- Water heating is the biggest source of greenhouse gas emissions.
- Heating is only responsible for 15 percent of total emissions.
