Senator CORMANN (Western Australia—Minister for Finance and Vice-President of the Executive Council) (14:18): I have provided an answer on record in relation to this. I don't agree with that description. Renewable energy is a very important part of our energy mix. In order to ensure that we can deliver affordable, reliable energy supplies, we need to ensure that we continue to make sensible decisions about the entire energy mix, which will continue to also rely substantially on Australian coal. Relying on Australian coal and demonstrating to the world how we are able to lower emissions through higher efficiency, lower emissions coal-fired power station technology will help reduce emissions around the world. If we displace ground coal, which is more polluting, with high-quality Australian black coal into HELE plants, that is a good thing for the environment. That is perhaps something that the Labor Party used to understand. If they thought about it, they might get their head around it again. The PRESIDENT: Are you on a point of order, Senator Watt? Senator Watt interjecting — The PRESIDENT: The minister has concluded his answer, Senator Watt. Senator Watt: I seek leave for Senator Canavan to reply. The PRESIDENT: You don't have the call, Senator Watt. Good try. Honourable senators interjecting — The PRESIDENT: Order! Can I hear Senator Siewert, please.
