The two pie charts compare energy use and greenhouse gas emissions in Australian households. Overall, heating consumes the largest proportion of energy, while water heating and other appliances are the main sources of greenhouse gas emissions.
Heating accounts for 42% of total household energy use, making it the biggest category. Water heating is the second largest at 30%. Other appliances represent 15%, followed by refrigeration at 7%. Lighting and cooling use the smallest amounts of energy, at 4% and 2% respectively.
However, the pattern is different for greenhouse gas emissions. Water heating produces the highest share at 32%, and other appliances are responsible for 28%. Heating contributes only 15%, which is much lower than its energy consumption. Refrigeration accounts for 14%, while lighting and cooling make up 8% and 3% respectively.
