SUPPLY AND USE
An overview of the supply and use of energy in Australia in 2004-05 is shown in diagram 17.4. Australia's total energy supply comprises primary energy production plus imports of energy. In 2004-05 Australia produced 17,524 PJ of primary energy products (including stock changes and statistical differences) and imported 1,470 PJ of energy products, mainly crude oil.
Australia's supply of primary energy products can be exported, converted into other (derived) energy products used by Australian households and industry, or stockpiled for future consumption. Most of the energy produced in Australia in 2004-05 was exported (13,153 PJ), the bulk of which was black coal (6,595 PJ) and uranium (5,287 PJ). More information on imports and exports of Australia's energy is provided in International trade in energy products.
In 2004-05, 5,841 PJ of energy was available for domestic use, of which, 4,465 PJ of primary energy was transformed into 2,446 PJ of derived energy. Losses from the production of derived energy, through the conversion process, distribution and transmission, accounted for 2,019 PJ of energy use. Australia's end users of energy, comprising households and industry (excluding the conversion sectors), used 3,822 PJ of energy, approximately one-fifth of the total energy supply.
