If you are a residential customer and can't find a recent gas or electricity bill, and don't know how much electricity or gas you use or how much you spend you can still use IPART's myenergyoffers comparison website to get an idea of the energy offers available in your area and how much you might pay for energy each year under different offers.
Energy use varies throughout the year and depends on the number of people per household, the type of dwelling, and the number and age of appliances in use.
IPART periodically surveys households in New South Wales to learn more about residential resource use and to collect the socio-economic, demographic and behavioural data that inform and strengthen our pricing review process.
Based on the results of our 2010 survey of households in the Blue Mountains, Illawarra and Sydney, we know that larger households tend to use more electricity than smaller ones. Typically
Further, residents of freestanding houses tend to use more electricity than residents of semi-detached dwellings and flats, and the more energy-intense appliances a household of any type has - such as air conditioners, refrigerators, dishwashers and swimming pools - the more electricity it uses.
The results of our 2010 survey also indicate that gas use varies by household size. Typically:
But gas usage also depends on what it is used for, and households that use gas only for cooking only use about 500 MJ per quarter. Furthermore, residents of freestanding houses tend to use more gas than residents of semi-detached dwellings and flats, and households in cold climates tend to use more gas than those in warmer areas.
