Energy

Renewable

Clean renewable electrical energy generation systems are becoming increasingly accessible to the average homeowner either installed at home and connected to the grid or purchased as GreenPower.  Download the Fact Sheet…

 Appliances

Household appliances and equipment account for about one-third of energy consumption and about 45% of greenhouse gas emissions in the average household. Download the Fact Sheet…

Heating and Cooling

Very little energy is needed to make a well-designed house comfortable. Appropriate insulation, which is essential for a comfortable house, combined with passive solar design and a draught-proofed building, can create low or even no energy requirements for heating and cooling (see Passive solar heating; Insulation). Highly efficient homes with no heating or cooling input are possible across much of Australia. Download the Fact Sheet…

Hot water service

Water heating is the largest source of greenhouse gas emissions from an average Australian home and the second largest segment of household energy use in Australia, after space heating and cooling. It accounts for about 21% of the energy and generates about 23% of the greenhouse gas emissions (DCCEE 2010). In Australia, about 48% of the energy used for water heating comes from natural gas, 45% from electricity, 3% from liquefied petroleum gas (LPG) and 4% from solar (DCCEE 2012). Electric water heaters in particular contribute to these emissions: only half of Australian homes use electric water heaters, but they contribute 80% of hot water greenhouse emissions. Reducing your hot water use and using renewable energy sources to heat water are great ways to reduce your environmental impact. Download the Fact Sheet…

Lighting

Lighting in homes consumes 8–15% of the average household electricity budget (or about 6% of its energy use) although the makeup of the installed lighting technologies, lighting design and user behaviour can make a difference. Efficient and well-designed lighting can yield household energy savings.  Download the Fact Sheet…
