The bar chart compares information about the rate of energy used in an average Australian household and it provides data about the greenhouse gas emissions because of this energy use.
Overall, it is evident that heating accounts for the largest proportion of energy usage, resulting in the high percentage of greenhouse gas emissions. Meanwhile, water heating, as the second highest energy consumer, is the biggest contributor to greenhouse gas emissions.
In terms of energy consumption, heating accounts for 42% of the energy consumed by an Australian household, making it the most substantial figure in the chart. Water heating follows at 30%. In contrast, other appliances consume only 15% of the total energy, while refrigeration, lighting and cooling make up 7%, 4% and 2% respectively.
Further analysis reveals that in terms of greenhouse gas emissions, water heating constitutes 32% of the total emissions. Other appliances are responsible for 28% of the total emissions. By comparison, the percentages for heating, refrigeration and lighting are 15%, 14% and 8% respectively. Cooling, on the other hand, contributes just 3% to the overall greenhouse gas emissions.
