I hear those opposite interjecting. I mentioned 'economic insanity' before. The dumbest thing we could do as a country would be the policy proposal that the shadow Treasurer took to the last election, which was to spend hundreds of billions of dollars on nuclear reactors which would push energy prices up, not down. The difference between this side of the House and that side of the House is that we are working through these issues in a considered and methodical way to invest more in cleaner and cheaper energy; those opposite have gone absolutely crazy, and the economy would pay a price as a consequence.
