Senator WO NG (South Australia—Minister for Foreign Affairs and Leader of the Government in the Senate) (14:58): I'll try and do my best. I'm not sure where you got to at the end of the question. But I think I understand the argument of the question, and if I don't then I'm sure the senator can follow it up with a supplementary question. But the proposition that we can simply stay with the old coal-fired power electricity generation and that that's going to give us cheaper energy is just no longer the case. And do you know how we know that? It is because no private sector entity wanted to invest in the new coal-fired power. An honourable senator interjecting— Senator WONG: Well, the private sector. An honourable senator: Only Senator Canavan. Senator WONG: I know Senator Canavan did! But my point is that the market showed us. Senator Babet, I do recall that in your first speech you talked about the benefits of the free market. What I'd say to you is that the free market has spoken on this. The free market has spoken on this, and it hasn't gone down the path Senator Canavan wanted. The PRESIDENT: Senator Babet, a second supplementary?
