Senator BRANDIS (Queensland—Attorney-General, Vice-President of the Executive Council and Leader of the Government in the Senate) (14:56): There is only one party that takes an ideological approach to energy policy, and that is the Australian Labor Party. We saw the result of an ideological approach to energy policy in the state of South Australia last year, when the entire state was blacked out because the Premier, Mr Weatherill, and his government did take an ideological approach. They struck a 50 per cent renewable energy contribution with the electricity market in South Australia without backing it up, so there was no redundancy in the system. That is what an ideological approach gets you. We take a pragmatic approach. We take an approach based on economics and based on engineering, not on ideology, so as to ensure that we have affordable electricity and secure supply while meeting our international commitments. The PRESIDENT: A point of order, Senator Macdonald? Senator Ian Macdonald: I could barely hear the minister in that answer, because of Senator Wong's shouting, and I am wondering if you could declare a suspension of the Senate so that Senator Farrell could explain to Senator Wong how to properly lead the opposition. The PRESIDENT: There is no point of order.
