ENERGY CONVERSION AND SUPPLY LOSSES
The energy conversion sectors represent an intermediate stage in the energy supply chain. These sectors transform primary energy products into more useful, higher value-added secondary (derived) energy products. Petroleum refiners, for example, transform crude oil into petroleum products such as petrol and diesel.
The main energy conversion sectors, comprising electricity generators, gas manufacturers, petroleum refiners, and operators of coke ovens and blast furnaces, are significant users of primary energy products. Of the conversion sectors, the petroleum refining and electricity generation sectors are the two main users of energy. In 2003-04 these two conversion sectors used 1,511 PJ and 2,334 PJ respectively (table 17.15). Since 1998-99 energy use by the petroleum refining sector has declined by 10% and energy use by the electricity generation sector has increased by 15% since 1998-99.
ENERGY END-USE BY SECTOR
In 2003-04, Australia's end-users of energy, comprising household and industry (excluding the conversion sectors), used 3,545 PJ of energy (table 17.16). This is an increase of 8.7% compared with energy end-use in 1998-99.
The transport sector (including household transport) is the largest end-user of energy, using 1,251 PJ in 2003-04. In 2003-04, road transport accounted for 80% (1,004 PJ) of the transport sectors energy use, with the remaining contributors being air transport (162 PJ), water transport (54 PJ) and rail transport (32 PJ).
The manufacturing sector is also a large energy end-user, using 1,138 PJ of energy in 2003-04. Together with the transport sector, these two sectors account for 67% of total energy end-use.
Energy end-use in the commercial sector and residential sector has grown by 11% and 9% respectively since 1998-99.
RESIDENTIAL ENERGY USE
Australia has a very high level of car ownership and use, and a high level of total personal travel. Table 17.17 shows, of people who work or study aged 18 years and over, the proportion driving to work or study has remained unchanged between 1996 (70.1%) and 2003 (70.3%).
The 1970s and 1980s saw an increase in the variety of energy-using home appliances available for purposes such as heating, cooling and cooking. Natural gas and electricity continue to be the key energy sources of space heating, water heating and cooking (table 17.18). In 2002, 81% of Australian residences had room heating, with the main energy source being natural gas for 34% of these residences (up from 31% in 1994), followed by electricity (31%) and wood (14%). Electricity is the major source of energy for both heating water (about 61% in 2002) and cooking (about 57% in 2002).
INDICATORS OF ENERGY USE
Australia's total energy consumption increased by 9% from 1998-99 to 2003-04. In this period the population increased by 6%, and gross domestic product (GDP) in chain volume terms increased by almost 18%. Consequently, there has been a continuing decline in Australia's aggregate energy intensity, that is, energy consumed per unit of GDP over the five-year period. While electricity use (up 19% in 2003-04 compared to 1998-99) marginally outgrew population growth over the period, it broadly matched growth in GDP (table 17.19).
