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 comb
