The two pie charts demonstrate the energy consumption in an average Australian household and the release of greenhouse gas generated from this energy utilization respectively.
A close look at the charts reveals that other appliances cause considerably large amount of greenhouse gas while heating being the lowest contributor in terms of energy usage to generation of hazardous gas ratio. It is also clear that the proportion of gas discharged by lighting is twice the amount of energy it consumes.
Heating makes up the highest proportion of energy usage at 42% while water heating consumes 30% of energy. Energy utilized for refrigeration is 7% which is about half of that consumed by other appliances (15%). Lighting and cooling consumption of energy stand at 4% and 2% respectively.
The second chart illustrates that 32% of greenhouse gas emission is caused by water heating whereas heating releases only 15% of gas. Refrigeration causes 14% of emission while other appliances contribute twice that amount - 28%. Lastly, the amounts of greenhouse gas discharged by lighting, and cooling are 8% and 3% respectively.
