Senator Cormann asked the Minister representing the Treasurer, upon notice, on 18 August 2011: With reference to the Treasury carbon tax modelling, Strong growth, low pollution: Modelling a carbon price: (1) What is the expected share of Australia's electricity generation that will come from wind power in 2020 and in 2050. (2) How many wind turbines will have to be installed to achieve these generation shares (given available data on the actual average power output of wind turbines, relative to their rated output). (3) How many new wind farms do these figures correspond to, given the current typical size of wind farms, and in what regions, in the modelling, will these wind farms be located.
