In 2018-19 energy use per household and aggregate industry intensity has continued to trend downwards:
- Energy use per household decreased 2.2% to 130.6 GJ/ Household
- Industry energy intensity decreased 1.4% to 1,600.4 GJ/ GVA
Defining energy intensity
Energy intensity is a ratio of energy consumed (GJ) per unit of economic output (GVA). Net energy use is used as the numerator as it represents final consumption.
Energy intensity changes can be caused by increased efficiency, structural change in industry contribution, or pricing variations.
Household energy patterns have shown that in 2018-19:
- Net household consumption was 1,268 PJ
- Annual energy costs per household were $5,255
