ENERGY SOURCES USED BY HOUSEHOLDS
Almost every household in Australia (99.8%) used mains electricity as a source of energy inside their dwelling. Nearly half (48%) used mains gas. Mains gas as a source of energy inside dwellings was most common in Victoria (82%). Furthermore, a higher proportion of households in capital cities used mains gas inside their dwelling compared with households outside capital cities (63% for capital cities and 23% for outside capital cities). Outside capital cities, LPG/bottled gas was more commonly used compared with households in capital cities (29% and 10% respectively). (Tables 6 and 7)
Just over half of hot water systems in Australian households were electric (52%) in 2011 while around a third were mains gas (36%). Of all hot water systems, less than one in ten were solar powered (8%). Northern Territory had the highest proportion of households with solar hot water systems (46%) followed by Western Australia (21%). (Tables 8 and 9)
