These two pie charts show a comparison between the Australian household energy use and its greenhouse gas emissions respectively.
In general, from the first graph we can clearly see that heating accounts for the most substantial proportion of the household energy use in Australia, while the water heating is the biggest ratio regarding to the greenhouse gas emission in the second picture
It is evident that heating and water heating add up to 72% of the total consumption in Australian family energy, which represent the biggest ratio, on the contrary, the least part is cooling, which only contributes to 2% proportion. Following the cooling, lighting is seldom used in Australia, merely with 4%
With the second pie chart, the water is the biggest ratio and is more than 2% compared with the first graph. Similarly, the proportion of cooling in the greenhouse gas emission is
