End-use energy intensity in Australia

The new report "Australia's final energy intensity unit" is investigating the impact of the Australian economy's energy intensity unit and its energy productivity over the past 30 years. This report has revealed that since the 1980's, energy productivity has improved by economic expansion, changes in economic structure and energy efficiency technologies.

The decline in energy intensity unit shows improvement in energy productivity, and the report shows that Australia's energy intensity unit has been decreasing since the mid-1980s. This means Australia's energy usage growth rate is lower than economic production. Enhanced energy productivity will help promote economic growth and improve social welfare

The report noted that the improvement in energy productivity is brought about mainly through the conversion of manufacturing and transportation sectors, including industrial processes and energy intensive transport modes. Structural changes to the service industry of the economy also have resulted in lower energy consumption.

For example, as the extraction of marginal deposits has increased, the energy consumption in mining has increased, not all of the power generation has increased in all sectors.

The report also examines the progress of technology and the impact of government policy. Results announced at national and departmental level

Australia's end use energy consumption unit is available from the Chief Economist Office of the Ministry of Industry and Science.

Explaining the change in energy consumption per year does not mean that the industry's energy usage method has undergone a structural change. These changes in energy intensity units over the years may reflect "temporary" changes in the production process, or short-term changes in the level or combination of consumed energy products. It is only possible to start with a long-term review on the structural influences that may be attributed to changes in the energy consumption pattern in industry. A more detailed analysis of the energy intensity unit over time is stated in the Australian energy account 2008-09 and the final energy usage in the Australian economy.

In this report the term energy intensity is often used. The energy intensity unit is the energy usage rate per activity unit. Since energy intensity is a simple calculation method, data is readily available and is therefore often used as a representation of energy efficiency. However, this approach is misleading. In addition to pure energy efficiency, energy intensity may capture the influence of many factors influencing energy demand, such as weather and structure change. Because of the inherent disadvantages of measuring energy intensity, OEE tracks energy efficiency in a way that measures changes in energy demand due to changes in activity, economic structure, service levels, and weather. In summary, energy efficiency measurements calculate these items from energy intensity calculations.
