The two pie charts illustrate the average energy usage and greenhouse gas emissions of Australian households. Overall, heating accounts for the highest proportion of energy usage at 42%, while greenhouse gas emissions are notably lower at 32%.
The first pie chart breaks down energy usage into several categories. Cooling, lighting, and refrigeration represent small proportions at 2%, 4%, and 7% respectively. Additionally, other appliances account for approximately 15%. The most significant categories are heating and water heating, which make up 42% and 30% respectively.
The second pie chart, which represents greenhouse gas emissions, shows that both cooling and lighting account for less than 10% of total emissions. However, heating and refrigeration have similar proportions, at about 14% and 15%. Moreover, water heating and other appliances together constitute nearly 35% of emissions.
In conclusion, the two pie charts display notable similarities, particularly in the low percentages for cooling and lighting, both under 10%. Additionally, both charts indicate that water heating accounts for a similar proportion of energy use and emissions, approximately 30% for energy usage and 32% for greenhouse gas emissions.
