The given pie charts provide information about the average energy used in an Australian household and the greenhouse gas emissions for the energy used, respectively.
Overall, it is shown that cooling, lighting, refrigeration, and other appliances use a low amount of energy, whereas they produce a large amount of greenhouse gas. On the other hand, heating has an opposite trend, and water heating’s energy use and greenhouse gas emission are almost the same.
The amount of greenhouse production from refrigeration, cooling, lighting, and other appliances is almost double that of their energy uses, which altogether contributes over half of the total gases. Heating uses two-fifths of the total energy, but produces only fifteen percent of greenhouse gases, which is the only sector where greenhouse production is lower than its energy uses. The energy uses and greenhouse gas emissions are almost the same for water heating, which accounts for nearly thirty percent of the total amount.
These figures represent the overall contribution to greenhouse gases from different sectors with their energy uses.
