The two pie charts demonstrate how energy is used in average Australian household and the ratio of greenhouse gas emissions into the environment as the result of this energy use.
Overall, the percentage of heating and water heating account for the majority of both energy use and greenhouse gas emissions , while cooling and lighting contribute the least.
In detail, the part of heating is the largest with 42% of household energy consumption and the second is 32% which belongs to water heating. Other appliances, refrigeration, cooling and lighting share remaining energy to use, with cooling is the lowest ratio at 2%.
Similarly, water heating produces highest amount of greenhouse gas with 32%, followed by other appliances at 28% and 15% of heating. Concurrently,cooling system and lighting make up to the smallest proportion again , at 3% and 8% respectively.
It is clear that amount of greenhouse gas released into the environment is more than the energy consumed by Australian household. However, heating is not directly proportional with the gas emissions, it uses much energy but emits a smaller amount of greenhouse gas.
