The first pie chart demonstrates the power usage of a typical Australian household, while the second chart presents data on the percentages of greenhouse effects of the power-consuming equipment in this country.
Generally, the more energy a household appliance uses, the more greenhouse gas it emits.
As can be seen, the energy that was used for water heating and keeping the house warm is half of the energy required in an average family. Refrigeration, lighting, and cooling utilize around ten percent of energy, whereas all other appliances consume the rest of the almost one-quarter energy share in this state.
As the second pie chart suggests, water heating and other equipment contribute to the highest percentage of gas emission, which is respectively 32 and 28 percent. The lowest amount of gas emission belongs to cooling and lighting, that is nearly 10 percent, and this correlates with the amount of energy that these equipment use. Cooking, stand by and lighting combinedly contribute to 14% gas production which is almost the same as the amount produced by other appliances in a house.
