Energy conversion and supply losses
The energy conversion sectors accounted for approximately three-quarters (4,317 PJ) of total domestic energy use in 2005-06 (diagram 19.4). The energy conversion sectors (including electricity generators, petroleum refiners, operators of coke ovens and blast furnaces, and gas manufacturers) transform primary energy products into more useful, higher value-added derived energy products. For example, petroleum refiners transform crude oil into petroleum products such as petrol and diesel.
The electricity generation and petroleum refining sectors are the two main users of energy. In 2005-06 these two conversion sectors used 2,424 PJ and 1,432 PJ respectively (table 19.12). Since 2000-01, energy use by the electricity generation sector has increased by 12% and energy use by the petroleum refining sector has declined by 17%.
Derived energy products
In 2005-06 Australia produced 2,461 PJ of derived energy products (diagram 19.4). These products included thermal electricity (847 PJ), automotive gasoline (570 PJ), diesel (397 PJ), aviation turbine fuel (192 PJ) and coal products (164 PJ) (table 19.13).
The production of derived energy remained essentially the same in 2005-06 as it was in 2000-01 (2,461 PJ in 2005-06 compared with 2,454 PJ in 2000-01). While the production of thermal energy increased from 740 PJ to 847 PJ (up 15%) in this period, there was a fall in the production of all petroleum products - automotive gasoline (down 13%), aviation turbine fuel (down 11%), fuel oil (down 38%), diesel (down 25%) and briquettes (down 79%). Other coal products increased slightly - coke up 3.4% and coal by-products up 2.7%.
Significant energy losses are involved in the process of transforming primary energy resources into derived energy products and in the delivery of derived energy products to the market. In 2005-06, almost a third (1,856 PJ) of the total energy available for domestic use was lost through the conversion processes and through distribution and transmission systems (diagram 19.4).
Energy end-use by sector
In 2005-06 Australia's end-users of energy, comprising households and industries (excluding the conversion sectors), used 3,785 PJ of energy, an increase of 12% since 2000-01 (table 19.14).
The transport sector was the largest end-user of energy, using 1,316 PJ in 2005-06. In 2005-06 road transport accounted for 78% (1,021 PJ) of the transport sector's energy use, with the remaining contributors being air transport (202 PJ), water transport (58 PJ) and rail transport (35 PJ). The manufacturing sector was the second highest user of energy (1,209 PJ) in 2005-06. Together with the transport sector, these two sectors account for 67% of total energy end-use.
