South Australia’s Strategic Plan is comprised of 100 targets. These targets are specific and measurable and enable us to measure our progress towards achieving the Plan’s visions and goals.
Each target is reported on through this section of the website. Data is analysed and uploaded as it becomes available.
Target:60. Energy efficiency – dwellings:
Improve the energy efficiency of dwellings by 15% by 2020
(Milestone of 10% by 2014)
The Energy Efficiency Index (EEI) is defined as the number of average residential dwellings that can have their annual energy needs met by a given quantity of energy – in this case 1 terajoule (TJ) of energy.
In 2014-15, it is estimated that 26.71 average South Australian dwellings could have their total annual energy needs met by 1 TJ. This is 23.79% higher than the number recorded in the baseline year of 2003-04 (21.72) and exceeds the 2014 milestone and the 2020 target. This current trend is influenced by energy efficiency policies (such as Minimum Energy Performance Standards, buildings standards, the Residential Energy Efficiency Scheme and SA's water heater installation requirements), policies promoting the residential use of photovoltaic systems, and consumer responses to rising energy costs.
Note: there are minor differences in the EEI reported in some years due to revisions in historic energy use estimates reported by the Bureau of Resources and Energy Economics (BREE). BREE data accounts for 20% of energy use used to calculate the EEI. BREE has advised of further changes that will be reflected in future reporting. Whilst these changes affect the reported EEI, they are of a minor nature and do not effect the overall trends in energy efficiency improvement and exceedance of the target.
