答案 The pie charts illustrate how energy is consumed and the distribution of greenhouse gas emissions caused by different purposes in an ordinary Australian family. For an average Australian household, overall, heating uses the majority of energy, which occupies 72% of the total consumption, including heating for warmth (42%) and water heating (30%). By contrast, the least energy is spent on cooling and lighting with 2% and 4% respectively. In addition, over one fifth of the energy is taken by household appliances, especially the refrigerator, which accounts for 7%. As for greenhouse gas emissions, water heating takes the lead, which contributes 32%, and it is closely followed by other appliances with 28%. Heating (15%) and refrigeration (14%) are very similar with only 1% difference. Similar to the energy use, the emissions resulted from lighting (8%) and cooling (3%) are still the smallest, which totally comprise 11% of the greenhouse effect per Australian household. In conclusion, the proportions of greenhouse gas emissions for different purposes basically follow the energy use percentages with a difference in heating, which accounts for 42% of energy consumption, but produces 15% of the greenhouse gas emissions.
