Ms LEY (Farrer—Deputy Leader of the Opposition) (14:51): My question is to the Acting Prime Minister. Is the Acting Prime Minister aware of a recent report from the US Department of Energy which shows that a renewables plus nuclear electricity grid is 37 per cent cheaper than a renewables-only grid. What is it that experts in the US and 19 out of 20 of the world's top economies know that the Acting Prime Minister does not know?
