The table below shows energy consumption by industry, total industrial added value and energy intensity unit data. The Australian economy's energy intensity unit declined by 1% from 2,650 GJ / $ m in 2008 - 09 to 2,613 GJ / $ m IGVA in 2009 - 10. This is usually reflected in the declining energy intensity of most industries in Australia between 2008 - 09 and 2009 - 10. For example, energy usage in the water and wastewater industry decreased by 5%, but IGVA increased by 5%. This will reduce energy intensity by 9%. Likewise, the energy use of the commercial and service sectors declined by 1%, but IGVA increased by 2%, and energy consumption unit decreased by 3%.
Differences in energy intensity between industries reflect the proportion of energy in a combination of different production processes and production inputs. This is shown in the lower energy intensity map, the manufacturing industry is the most energy intensive industry in the Australian economy, followed by transportation and mining. Business and service industries such as retail, health and education are non-energy intensive industries.
