The given two pie-charts displays the usage of energy for various purposes and greenhouse gas emissions in Australia in six categories: water heating, refrigeration, heating, cooling, lighting, and other usages. The data are calibrated in percentage.
In overview, in energy use chart , the most of the energy is consumed for heating purpose and least is used for cooling purpose. A similar trend is observed in greenhouse gas emissions, with heating again being the most significant contributor and lighting the least.
In detail, first chart depicts, 42% of energy consumed in an Australian family is emitted due to heating, which is the highest figure on the chart , followed by that of water heating at 30%, covering more than 70%. Meanwhile, the remaining less than 30% was divided into four other sectors : other usage 15% , refrigeration 7%, and lighting 4%. Cooling recorded the lowest percentage of energy consumption , with only 2%.
Furthermore, the second diagram is a detailed breakdown of gas emission from different energy-consuming activities. It shows that water heating had a highest share of gas emission which is 32%, followed by other appliances,28%. Additionally, refrigeration, heating, lighting’s share was 14%, 15%, and 3% respectively. Cooling, again had a minor share of gas emission of 3%.
