The provided pie charts illustrate various types of energy used by an Australian family, as well as the greenhouse gas pollution produced by these energy sources.
Overall, it can be seen that the energy used and the greenhouse gas emissions produced by an Australian household are categorized into six different groups. While heating was responsible for the highest share in the former, water heating had the greatest percentage in the latter.
According to the first chart, heating ranked first with 42%. The contribution of water heating was twice as high as that of other appliances, which stood in second and third place (at 30% and 15%, respectively). Finally, refrigeration, lighting, and cooling together comprised less than 15%.
Looking at the second pie chart, there was a small difference between the share of water heating and other appliances in Australian household greenhouse gas pollution, with the former standing first at 32%. Similarly, there was a narrow margin of 1% between heating and refrigeration proportions, which together formed about 30% of gas emissions. Ultimately, the allocation of cooling was approximately 1/3 as high as that of lighting, with the former being responsible for the least at 3%.
