The big mover in the first two years is wind. Small amounts of photovoltaic solar, geothermal and biomass are also added, helping to back-up the new wind power.
The combination of wind's massive growth, assisted by other technologies and immediate efficiency gains allows the first polluting coal plants to be retired. The capacity of other coal plants, including Hazelwood and Munmorah, is halved.
Several new technologies pick up pace, including concentrating solar power (CSP).
Australia's dirtiest power station, Hazelwood, closes in early 2013 after 42 years' operation. In NSW, wind and CSP combine to replace coal plants at Liddell and Munmorah. Other plants close down or reduce output in Queensland and WA.
Renewables are now making major headway in Australia's power sector. Ocean energy makes its first appearance supplying electricity to Victoria, while geothermal and solar continue to expand faster.
South Australia becomes the first state to phase out coal-fired electricity, as geothermal and wind power combine to replace Northern power station.
Ocean energy expands in Victoria, and begins supplying significant power needs for Tasmania, WA and SA.
Large-scale solar projects in SA and north-western Victoria help build the region's energy hub that geothermal power initiated.
Continued closures and phase-outs of coal plants, including Eraring in NSW.
The widespread deployment of CSP is the main source of around-the-clock electricity that replaces the remaining 10 coal plants.
By the end of 2020, Australia has replaced all of its coal-fired power stations with renewable energy.
