The first pie chart shown below represents the share of energy used by household appliances in Australia. The second chart depicts the percentage in which greenhouse gas is emitted while using these appliances.
Overall, we can see that majority of the energy is used for heating whereas the greenhouse gas emitted from the heating sources accounts for about 50 per cent. The least contribution on both accounts was by cooling activities in Australian homes.
A couple of energy applications consume more share of energy and emit a lesser percentage of greenhouse gases. Although heating uses the majority portion of the power at 42% in an average family, it contributes only 15% to emissions. Similarly, refrigeration accounts for 14% of energy usage but only 7% of emissions.
On the other hand, another couple of applications contribute to about twice as much greenhouse consumption as energy consumption. While other appliances and lighting share 15% and 4% of energy usage, their share in the emission is 28% and 8%, respectively.
Lastly, water heating and cooling had almost equal contribution on both accounts. They consumed 30% and 2% of the energy consumption whereas they emitted 32% and 3% of greenhouse gases respectively.
